UNAS I DISCUSSION OF DIVERSION TUNNEL HYDRAULIC SLIDE GATES OPERATING SYSTEM YDROELECTR ROJECT The diversion tunnel control gate is normally closed and the guard gate is normally open. In the event of a substantial earthquake the reservoir must be drained rapidly for inspection/safety of the dam. Therefore, the highest degree of reliability must be incorporated into the design of gate operating system. The system has been designed with the following components: Ts Accumulator bank sized for one stroke (one-half cycle) with a small single phase motor/pump for charging the bank. 2. Diesel engine/pump sized for operation without the accumulator bank. Re Diesel engine-generator at the power tunnel gate house for operating the accumulator's motor/pump. 4, Facilities for hooking up a portable engine-generator for operating the accumulator's motor/pump. The operating system for the slide gate will be functional with the following level of failures: a £nQ Tr « Level 1: Loss of Line Power The accumulator bank will be fully charged at all times. To open the control gate would require engagement of a single solenoid valve. Level 2: Loss of line power and damage to the accumulator bank After isolation of the accumulator bank, the gate can be opened at normal speed with the use of the diesel engine/pump. Level 3: Loss of line power, damage to the accumulator bank, and the diesel engine/pump will not start. After isolation of the accumulator bank, the engine generator ‘at the power tunnel gate house is running, the gate can be opened slowly with the use of the small single phase motor/pump. Level 4: Loss of line power, damage to the accumulator bank, diesel engine/pump and the diesel engine-generator will not start. After isolation of the accumulator bank, a portable engine-generator will provide power for the small single phase motor/pump. The gate operating system will be controllable from the power tunnel gate house for a Level 1 failure. Level 2 through 4 will require operation from the diversion tunnel gate house. a eno rt a meet Re } a ad i te eal TABLE OF CONTENTS MENOCRIOUON.

Back Cover introduction Hydraulic Systems for Gate Operation Rodney Hunt hydraulic systems for gate control have for years provided advantages and economies in installa- tions all over the world. Operation of gates by hydraulic cylinders, together with the hydraulic operating system, should be considered for the operation of all gates just as manual and electric actuators are considered. There are many installations where the flexibility and reliability of hydraulic cylinder operation of gates would provide better performance than other methods of operating these gates. Where several gates are operated by a single hydraulic operating system, considerable cost savings can result. The purpose of this brochure is to provide basic information on hydraulic systems and to assist in the selection of the proper system and equipment to meet the desired performance requirements.

Copyright 1984 Rodney Hunt Company Orange, Massachusett Cover Photograph OD Two hydraulic cylinder operated 14 ft. x 16 ft. roller gates are used to control the cooling water in a nuclear power plant. The gates must open in a fail-safe situation. Two identical and redundant hydraulic systems provide the normal and emergency operation of these gates. 5 © Hydraulic Cylinder Actuators When hydraulic cylinders are used to operate sluice gates they are mounted in a vertical position directly above the gate and are connected to the gate by means of an operating stem. When self-contained sluice gates or slide gates are used, the hydraulic cylinder is mounted directly on the yoke of the gate and the piston rod is connected directly to the disc of the gate by means of a thrust nut. When the gates are not self-contained, the hydraulic cylinder is mounted on the floor above the gate or ona support bracket, and an extension stem is coupled to the piston rod of the cylinder and, in turn, connected to the gate. Hydraulic cylinders are standard products of a number of qualified manufacturers. The cylinder normally consists of steel heads, a steel barrel, a steel piston and a stain- less steel piston rod. Lip type seals are used to eliminate leakage past the piston, and “O” rings, or pressure actu- ated seals, prevent leakage of oil out of any part of the cylinder. Tie rod construction is most often used. The top and bottom heads of the cylinder are connected by high strength steel tie rods. A tail rod, which is connected to the piston and extends through the top head of the piston can be provided for position indication or emergency operation. Where the cylinders may be operated at relatively high speeds, a cushion is provided in the bottom head to slow the speed of the piston at the end of the stroke. Other options are available such as special materials and plating of the heads and cylinder barrel for additional corrosion resistance.

Hydraulic Fluids There are a variety of hydraulic fluids that can be used in hydraulic systems. The choice of the fluid will depend upon the type of application and the location of the system. The fluids can be grouped into two general categories; petroleum fluids and fire resist- ant fluids. The petroleum fluids should be used if possible because they are readily available and the least expensive. The advantages and disadvantages of each group of fluids are described below. PETROLEUM FLUIDS Petroleum fluids are the most common hydraulic fluids and are used in most systems. They are inexpensive and are compatible with most standard seals used in cylin- ders and valves. They are suitable for operation in a wide temperature range and have excellent lubricating qual- ity. They provide excellent corrosion protection, have a desirable specific gravity and good viscosity index. The disadvantages are that they have some toxicity and should not be used where leakage into drinking water may occur. They also have a relatively low fire resistance and should not be used where they may be exposed to an open flame. Rodney Hunt recommends a good grade of fluid designed specifically for hydraulic applications, simi- lar to Shell Tellus 23, Mobil DTE 24, or equal. FIRE RESISTANT FLUIDS It should be noted that the term “fire resistant” does not mean “fire proof”. Fire resistant fluids will burn but have a much higher ignition temperature than petroleum hydrau- lic fluids. There are two broad types of fire resistant fluids. Synthetic — these are man made fluids which are rela- tively expensive and have a limited compatibility with standard seals. They have a wide operating temperature range and excellent lubricating qualities. They also pro- vide excellent corrosion protection, but have undesirable viscosity and specific gravity characteristics. In addition to the higher material cost, these fluids often require additional costly modifications to the system. Where re- quired forthis application, Rodney Hunt recommends the use of Quintolubric #822, Houghto-Safe lil, or equal. Water Based — there are several types of water based fluids including water in oil emulsion, oil in water emul- sion, and water with chemical additive. These are gaining in popularity due to their low cost, excellent fire resist- ance, and seal compatibility. However, they have a num- ber of limitations. They have narrow operating pressure and temperature range, limited lubricating quality and provide poor corrosion protection. In general, they are not recommended for use in sluice gate applications. WATER AND AIR Water and air can be used in hydraulic systems that oper- ate gates. Both have the advantage that they are quite often readily available where hydraulic cylinders are be- ing used. They are also nontoxic. They are not used very frequently, however, because there are a number of dis- advantages to their use. The principal disadvantage of water is that it may corrode materials used in the system. As rust particles form they can lodge in various valves = and seriously affect the performance of the system. Also, where water from municipal systems is used, the pressure is usually less than 150 PSI. This low pres- sure results in large cylinders, piping and nonstandard valving. Air also has the disadvantage that it is usually available only in low pressure, 100 PSI or less, so large compo- nents are required. If moisture is not completely removed from the air, corrosion of the parts can result. Also, the compressibility of air may produce problems in operation and control of the cylinder. AWWA System Pressure The AWWA Sluice Gate Specification, AWWA C501-80, contains a specification for hydraulic cylinders for the operation of cast iron, bronze mounted sluice gates. The pressure selected for the operation of these gates is 2000 psi. This pressure allows the use of standard components which are suitable for 3000 psi for adequate factor of safety. This pressure allows the use of smaller components than would be possible with lower pressures, thus reducing system costs. Cylinder sizes, the reservoir, and the quantity of oil required are all reduced when the 2000 psi pressure is used instead of lower pressures. Hydraulic systems designed for 2000 psi operating pressure have been used success- fully for many years to operate gates. 5 Advantages of Hydraulic Actuation Some of the advantages of hydraulic cylinder actua- tion of gates and valves are listed below: 1. Hydraulic cylinders are inexpensive compared to any other type of actuation, other than manual. 2. There are standard hydraulic cylinders available for operation of sluice gates in almost all applications. 3. There is a large number of high quality cylinder manu- facturers from which to choose. 4. The sluice gate can be designed to open or close at different speeds. Simple speed control valves allow speed of operation from very slow to approximately 10 ft. per minute without danger to the sluice gate. Faster speeds can be achieved if necessary. 5. Since there are no screw stems used there is no nut wear involved for gates that must open or close fre- quently or are used for modulating service. Cylinders can be used for this type of difficult service without concern for wear. : £ 6. A number of sluice gates can be operated from the same hydraulic system resulting in substantial cost re- duction. 7. The hydraulic systems can be designed for many functions. The systems can vary from the very simple pushbutton station for open and close operation, to the most complex systems using remote computer controlled positioning. 8. Emergency gate closing and opening in the event of power failure, high water level or other emergencies are easily obtained with hydraulic cylinders. 9. Using the normal 2000 psi oil pressure, all of the components of the hydraulic system are standard and readily available, thus minimizing the problems and costs of maintenance. Because the systems are proven at this pressure, leakage is not a problem. Where there is con- cern about leakage of the fluid into the water, special hydraulic fluids can be used that have low toxication. 10. Hydraulic cylinders can be used in very difficult appli- cations where they are submerged, exposed to severe corrosive atmosphere, installed in regulating chambers under the street and in similar applications by providing corrosion resistant materials in the construction of the cylinder or by providing coatings for the cylinder. Chrome plated stainless steel piston rods are recommended so Q™ pitting or corrosion of these rods does not occur. 11. Hydraulic actuation is ideally suited for areas requir- ing explosion proof equipment. The cylinder can be mounted in the hazardous area with the hydraulic system mounted remotely in a safe environment. SINGLE SOURCE RESPONSIBILITY Rodney Hunt has the unique capability to design hydraulic systems, provide the necessary drawings for customer approval, manufacture the systems and test them at the factory prior to shipment, and pro- vide expert start-up service. This capability provides the consulting engineer, the contractor and the end user with single source responsibility for the gate equipment and the hydraulic system. It is not neces- sary for the contractor or purchaser to coordinate the various suppliers of the different equipment. If there are problems in the proper operation of the system, Rodney Hunt designed the system, built it, tested it and can best solve these problems.

ELECTRIC AND PNEUMATIC CONTROLS The control system used in a hydraulic system can be either electrically or pneumatically operated. In most ap- plications, the use of the electrical controls will be simpler and less expensive. Electrical controls allow greater flexi- bility, are easier to install and are more reliable. Where electricity cannot be used for the control system, the pneumatic system is a practical option. The pneumatic system can respond to pneumatic signals, can operate the necessary directional valves and provide most of the same options available with the electric system. The air used in the pneumatic system must be clean and dry. An advantage of the pneumatic system is that it is possible to store air under pressure to provide control during periods of power failure. Symbols Used on Hydraulic Schematic Diagrams be 2 © RESERVOIR The container or source of the fluid being pressurized. PUMP The pump raises the fluid pressure from at- mospheric to the desired system pressure. It can be fixed or variable displacement and is usually motor driven. Hand pumps are often used as part of the emergency back-up sys- tem. FILTER A device installed between the reservoir and the pump and in the discharge line to the reServoir to remove impurities from the hy- draulic fluid. The filters may be provided with a bypass to allow flow of oil when the system is clogged to prevent damage to the system. PRESSURE RELIEF VALVE A valve which allows the oil to flow directly back to the reservoir when a predetermined pressure is reached. This prevents system pressure from exceeding this predetermined setting. PRESSURE GAUGE The gauge indicates fluid pressure at vari- ous points in the system. PRESSURE REDUCING VALVE A valve that reduces the system pressure to a lower pressure. In sluice gate applications it is desirable to have the pressure used to close the gate lower than the pressure avail- able to open the gate because of the differ- ence in area between the top of the piston and the underside of the piston where the rad ic attachad FLOW CONTROL VALVE A valve that consists of a check valve and a throttling valve. The check valve allows flow in one direction and prevents flow in the op- posite direction. The flow in the opposite di- rection is forced to pass through a needle valve or other type of control valve which can throttle the flow. In this way the speed of operation of the cylinder can be controlled in both the opening and the closing direction. CHECK VALVE Avalve used to allow flow in one direction but stop the flow in the opposite direction. PILOT OPERATED CHECK VALVE This type of valve involves two check valves in a single body. The line pressure from one valve causes the opposite valve to open. DIRECTIONAL CONTROL VALVE A two-position or three-po- sition valve which is actu- ated either manually, elec- trically or pneumatically. It directs the oil under pressure to either the top or the bottom of the cylinder and returns the oil from the opposite end of the cylinder to the reservoir. PRESSURE SWITCH A switch that is actuated by pressure, norm- ally used to start and stop the pump at prede- termined pressures. ACCUMULATOR An accumulator is used to store oil under pressure. It is normally precharged with an inert gas, which is separated from the oil by either a bladder or a piston. It is used to provide emergency operation when the pump and motor are not operating and also used to prevent frequent operation of the niuimn 3 Hydraulic Systems i 2 yc ee PUSHBUTTON OPERATION TYPICAL APPLICATION Hydraulic Systems it i= aa PVCS felts vo) aa: TYPICAL APPLICATION myaraulic systems RODNEY ) Cay) TYPICAL APPLICATION OPTIONS mMyaraulic system Specifications The Specifications for hydraulic systems should consist of two sections.

The position transmitter shall be located at the cylin- der and shall transform the linear motion of the gate to a variable electrical signal. b. The receiver, which is located remotely from the cylinder, shall receive the transmitter signal and indicate the position on a dial. c. The position indication system shall be as manufac- tured by DeLaval-Gem Sensors Division; Celesco, or equal. ‘Engineering Information OIL FLOW CAPACITY OF PIPES Where hydraulic systems are used to power hydraulic cylinders to open and close gates and valves, it is neces- Sary to install piping between the system and the cylinder. The size of the pipe depends upon the amount of fluid to be transmitted and the velocity that will be allowed within the pipe. For most hydraulic systems using 2000 psi oil pressure, Schedule 80 (extra-strong weight) pipe will be used. The amount of oil to be transmitted is determined by the speed of operation of the gate required and the cylinder size. Using the chart on page 17 it is possible to deter- mine the amount of oil required in a cylinder for each inch of travel. If the gate is to travel at 24” a minute, the total gallons per minute of oil required can be determined. Once the flow of oil has been determined, the chart below can be used to determine the pipe size using the recom- mended range of oil flow velocity within the pipe for the different uses. The pipes may be pump suction lines, pressure lines or fluid return lines. FACTS AND FORMULAS An example of the use of the chart would be a require- ment for 25 gallons per minute of flow in the pressure line between the system and the hydraulic cylinder. Accord- ing to the chart, a 9/4” diameter pipe could be used. Pipe size should be selected on the basis of oil flow veloc- ity. Undersizing results in high pressure losses and sys- tem overheating. Oversizing reduces pressure and power losses but may increase the cost of the piping. PUMP SUCTION LINES Size chosen should keep oil velocity within the range of 2 to 4 feet per second. PRESSURE LINES Size chosen should keep oil velocity within the range of 15 to 20 feet per second. OIL RETURN LINES Size chosen should keep oil velocity within the range of 10 to 15 feet per second. Schedule 80 SIZING THE HYDRAULIC CYLINDER The size of the hydraulic cylinder depends upon the out- put thrust required to open the gate and the pressure that will be available at the cylinder. The thrust necessary to open the gate can be calculated using the Hoist Bulletin of the Rodney Hunt catalog, Section WCE78-5. The cal- culated thrust necessary to open the gate should be in- creased by 25% to provide a factor of safety. The result- ing thrust is the force used to determine the size of the hydraulic cylinder. The pressure available at the cylinder depends upon the system pressure and the amount of losses between the pump and the cylinder. The system pressure that is most often recommended is 2000 psi. The chart indicates the output thrust of various cylinders at different operating pressures. The force on the push stroke is when the piston rod is being extended and the full area of the piston is acting. On the pull stroke when the piston rod is being contracted, the area of the piston rod must be subtracted from the area of the piston to de- termine the available area acting. There are several rod diameters available for some of these cylinder sizes. The output force for operating pressures not indicated in the chart can be calculated using the ratio of the actual operating pressure to the operating pressures given in the chart. An example of cylinder sizing is as follows: With an operating thrust, with the 25% added, of 21,100 Ibs. and a system pressure of 2,000 Ibs., a preliminary se- lection of cylinder size would seem to indicate a 5” diame- ter bore cylinder with a 3” diameter piston rod. At 2000 psi this cylinder will have a pull stroke of 25,180 Ibs. This is more than the required thrust so the 5” diameter cylinder is adequate. craemenrrersre sm mptiet: Questions and Answers In what types of applications is it advanta- geous to use hydraulic cylinder actuated sluice gates? There are many applications where the hydraulically ac- tuated sluice gate with a suitably designed system are advantageous. A partial list is as follows: 1. Applications where the sluice gates are for modulating service or are frequently operated 2. Applications where a number of gates can be oper- ated from a single system 3. Applications where the ability to change operating speed is desirable 4. Applications requiring fail-safe or emergency closing or opening 5. Applications where the actuator must be submerged 6. Applications where the actuator is required to be explosionproof What makes hydraulic operation suitable for explosionproof or submerged appli- cations or where the atmosphere is poor? The cylinder actuator can be submerged or safely placed in a poor atmosphere while the hydraulic system is lo- cated in a dry area remote from the cylinder actuator. The cylinder has no exposed moving parts except the piston rod and can be made of corrosion resistant materials or can be adequately coated to resist corrosion. Can a single hydraulic system be used to operate more than one gate? Yes. As many as necessary. If three or more gates are op- erated from a single system, depending upon the com- plexity of the system, the actuator will probably be cheaper than using electric motor driven actuators. Is it possible to adjust the speed of closing or opening where several gates are oper- ated from a single system? Yes. The speed of operation of each gate is controlled in- dependently for both opening and closing. Are hydraulic cylinders and controls readily available? There are a large number of hydraulic cylinder manufac- turers who make cylinders suitable for sluice gate opera- tion. There is also a very large selection available of all of the components for the hydraulic system. Rodney Hunt uses only widely known brand products that have a repu- tation for good quality and are widely available in all parts of the country. How reliable is the cylinder and system? Very little can go wrong because of the few moving parts in the cylinder. All parts of the system are standard off- the-shelf items that have proven to have long life. What prevents the gate from drifting closed when it is operated with a hydraulic cylinder? Lip seals are placed on the cylinder piston and the piston rod, and leak-tight pilot operated check valves are pro- vided on the power system unit. Piston Piston Cylinder Lip Seals Barrel Cylinder Heads Cutaway view of a hydraulic cylinder How far from the cylinder can the power sys- tem be located? Normally, up to 100 yards, but by specially designing the system this distance can be increased. Should the power system equipment be ina housing? Where the power system is located within a building, a separate housing is not required. If, however, the system is to be outdoors or exposed to corrosive atmosphere, then the system should be in its own separate housing. Where the atmosphere can be hazardous, it is desirable to enclose the complete system within an explosionproof housing. A better solution is to install the hydraulic sys- tem outside of the hazardous area. What pressure is recommended for system operation? A system pressure of 2000 psi offers a comfortable mar- gin of safety for readily available equipment rated for 3000 psi and is a high enough pressure to result in rea- sonably sized hydraulic cylinders and controls. Are there any parts of the total system that Rodney Hunt will not furnish? Yes. Rodney Hunt will not furnish the tubing or piping that interconnects the hydraulic cylinders to the power sys- tem, nor will they provide the electric wiring necessary to bring the power to the control panel. What are the normal and maximum speeds of operation? The gate opening and closing speed is usually between 12” per minute and 36” per minute. For those applications requiring fail-safe opening or closing in an emergency speeds as high as 15 ft. to 20 ft. per minute can be obtained. What type of fluid is recommended for these systems? In most cases, any good grade of hydraulic fluid is ac- ceptable. Rodney Hunt normally uses Shell Tellus 23 hy- draulic fluid in standard applications. Where a fire retard- ant fluid is required, Quintrolubic 822 is recommended. In applications where the hydraulic cylinder is to be used in the vicinity of potable water, Rodney Hunt normally rec- ommends Ucon FDC 300 manufactured by Union Carbide. What about air and water as pressure mediums? Air has the disadvantage that it is not compressible and, therefore, it is difficult to obtain smooth motion of the pis- ton in the cylinder. It also has the disadvantage that it is normally low pressure so that large cylinders are re- quired. Air must also be clean and dry, which adds to the expense of the system. Water is normally used at pressures of 150 psi or below and, therefore, large components are required. It also has the serious disadvantage that it will corrode parts of the system and small rust particles will cause the valves to become inoperable. Air and water when used as pressure mediums, have the advantage that they are quite often available where the cylinders are used and they are nontoxic. RODNEY HUNT How is local position indication obtained? If a tail rod is provided with the cylinder, then local position indication can be by means of a clear plastic pipe cover mounted over the tail rod with mylar markings on the pipe cover, or by means of a graduated scale installed beside the tail rod. If no tail rod is furnished then a rod attached by a bracket to the stem can be used. Is remote position indication available? Remote position indication can be obtained in several ways. A tape or cable can be attached to the gate or toa bracket attached to the stem. This cable passes over a pulley wheel which drives a potentiometer. There is also a fully encapsulated position indicator using magnetically operated reed switches which is advantageous for sub- mersible or explosionproof applications. t Continuous position transmitter and external limit switches activated by the hydraulic cylinder tail rod Will Rodney Hunt accept total system responsibility? Yes. Rodney Hunt will size the hydraulic cylinder and the complete system, design the system to meet the perfor- mance requirements, test it prior to shipment and guaran- tee its performance. oT aye, Wistalation and Maintenance STORAGE Hydraulic cylinders should be filled with the hydraulic fluid that is going to be used in the system and stored vertically to prevent damage to the seals. If the cylinders are too long to be stored vertically, they may be stored on their sides but must be rotated once a month to prevent seal damage. Hydraulic systems should always be stored indoors prior to installation. INSTALLATION Extreme care should be used in the movement and han- dling of the hydraulic system. Many of the components are sensitive and easily subject to damage if not pro- tected. Most units are provided with lifting eyes for han- dling with overhead facilities, or are designed to be lifted by a forklift truck. Electrical Connections — Electrical connections for the power unit are all made at a terminal strip located in the enclosure. The terminal strips are clearly marked with the proper voltage. Each unit is shipped with the complete system schematic diagram located in the enclosure. Proper rotation of the motor is indicated by an arrow on the motor. This should be checked by jogging the motor when the connections are made. Reversing any two power leads will change the direction of rotation of the motor. Hydraulic Connections — All hydraulic connections made to the hydraulic power system are made at the out- let end of ball valves. The ball valves are marked to clearly indicate which ball valves should be connected to the top of the hydraulic cylinder and which to the bottom of the cylinder. The piping connection to the hydraulic cyl- inder should include a valve on each pipeline at the cylin- der and a union so that the connection can be broken easily. It is recommended that air bleed valves be in- stalled at the highest point in the lines. If the system has separate accumulators, they should be connected to the designated ball valve port. RODNEY HUNT COMPANY ORANGE, MASSACHUSETTS 01364 U.S.A. Filling the System — The system should be filled with the recommended fluid by filling the reservoir and pump- ing the oil through the system. As the system is filling it will be necessary to refill the reservoir as required. With the system completely filled the reservoir should be at approximately the midpoint of the gauge glass on the reservoir. Important When filling the system with oil the connections at the cylinder should be disconnected and oil be al- lowed to flow out of both pipes in sufficient quantity to insure that the pipes are flushed clean. The con- nections to the cylinders can then be remade and the cylinder filled with oil. The cylinders should be cy- cled several times to insure that all air is discharged from the cylinder. MAINTENANCE Proper maintenance of the hydraulic cylinder is simple but crucial. The filters and strainers in the system should be changed at least once a year. Any loss of fluid over time should be replaced periodically with the same hydraulic fluid. The fluid should always be - in the mid-area of the gauge glass when the gates are closed. All Rodney Hunt systems are thoroughly tested at the plant, but if leakage should occur while the system is in use, the joints should be tightened to prevent the loss of oil and the possibility of air getting into the system.

Criteria calls for 2 1/2 ft/day drawdown limit, allows for 40 to 45 day drawdown period, with 1500 cfs inflow (includes Middle Fork inflow and high-two month summer flow during drawdown). Limitation was based on dam drawdown (critical for dam face stability). Dave Eberle was concerned about joint use of Diversion Tunnel and Power Tunnel for drawdown, therefore need tight operational control in project operating criteria. Explained why steel penstock was used instead of gate and open tunnel; and the gate hydraulic accumulator system. Discussed why accumulator system instead of positive displacement pump: more reliable and only 10% of power demand. Mr. Eberle wants SWEC to prepare letter on options and discusssion thereof and cost of standby portion of system. Gates and penstock concept accepted. - Access: spiral stairs will be usually used - for annual inspection only. Offset gatehouse so crane can access. Will raise lid and shaft collar about 3 ft. - Contracting: Anticipate one vendor for entire gate and operating system - performance specifications only, just like a crane with specifications on usable materials and speeds, etc. Estimate 4 serious vendors minimum, interest to date from: Mitsubishi Heavy Industries Johnson Machine Works, Inc. OLD ACTION ITEMS DISCUSSED (continued) SEQUENTIAL ACTION ITEM: ACTION Lakeside Bridge & Steel Trowbridge Industries Stewart Machine Company Allis Chalmers Corp. Dravo Wellman Piping anticipated to be all exposed, then unistrut mounts with covering in shaft. Pipe size = 1 in. diameter. Explained why bonnetted gates. - Metal seal gate - stainless and bronze. High tech bearing surfaces considered, but tend to creep - these gates will be static, not much chance, for recovery gf materials. Gates now 75 ft”, were 120 ft”. Gate vent pipes sizing conceptual only at this stage. - Penstock design with couplings and sliding saddles. Fish by-pass will manifold into individual nozzles. Will discuss amount of wasteage from system likely to occur (with 40 cfs/100 cfs fish release compensation flow requirements) in later letter. Manifold handles compensation flow requirements, reduced flow would save mostly on lost energy costs, not capital cost. - Explained butterfly valve and nozzle, ball valve and expansion cone alternatives for for manifold. Gate valves and nozzles considered for design. Sump set to discharge above the tailwater. Cone would allow free draining but nozzles do not. - Downstream: - showed rating curve, about = 10,000 cfs to start inundation. 6,000 cfs is about 5 ft below 1077 deck. Control valves all on/off. Will use manual valve operation for guard values. Emergency release gates are manual only. Fish by-pass operation is only automatic system at diversion tunnel. Mr. Eberle says OK on concept, look at economics of accumulators. No on-site maintenance provision for gates - OK. Gate = 10,000 1bs each. = Main gate shaft very similar to diversion tunnel, just a bit larger. = Put options for emergency operating system on FERC agenda for presentation.

Stafford DATE: July 11, 1986 Deputy Project Manager/Bradley FILE NO.: TELEPHONE NO.: SUBJECT: SWEC/APA 794 Peter N. Hansen h Wa Rural Systems Engineer Reference letter SWEC/APA 554, drawing FJ-2202B: It is recommended that SWEC specifies an emergency generator with a remotely mounted radiator with an electrically driven fan. The radiator should be placed in a closed plenum with a separate air intake and with a gravity damper on the air outlet. The radiator fan should be directly driven by a two speed motor controlled by a AMOT 2340E thermostatic switch installed in the coolant return line. The generator room should be provided with an exhaust fan and an intake air filter. These items should be sized for ventilation adequate for removal of radiated heat and heat from generator cooling. It is recommended that SWEC specifies an insulated exhaust system. Reference SWEC/APA 641: A flat plate heat exchanger is still recommended for the flowing reasons: 1. Part load characteristics of flat plate heat exchangers are fully adequate for this purpose and can be specified. 2. Tube and shell heat exchangers are definitely not more reliable than flat rate plate heat exchangers. Tube and shell heat exchangers rely on the integrity of the tubes as well as the tightness of the tube-to-end wall con- struction. A leak in a tube and shell heat exchanger can only be detected through an apparent loss/addition of fluid in the closed cooling Toop. A Yeak in a flat plate heat exchanger can occur in two ways: Either through a hole in a plate (very rarely seen) or through a rubber seal leak. A rubber seal leak is always drained to the exterior of the heat exchanger and thus it is easily detected. Such leaks are, however, also very rare. 3. Fouling is normally less of a problem in a flat plate heat exchanger due to the uniformity of flow velocities throughout the heat exchanger. Also, on flat plate heat 5134/618/1 exchangers, the fouling problem can easily be handled through correct specification. If SWEC feels comfortable with using penstock water in the generators in an emergency, one heat exchanger will be sufficient. 4. Space requirement. A flat plate heat exchanger needs only 1/5 of the space needed for a tube and shell ex- changer when space required for dissasembly is con- sidered. Reference: Pressure loss. The statement made by SWEC that a higher pressure loss results in additional cost savings is simply incorrect. It may result in a slightly reduced installation cost; however, these savings become absolutely insignificant when the added pumping costs are con- sidered on a life cycle cost basis.

Eberle Reviews Project Manager As a result of separating the powerhouse construction from the general civil construction, the recent 60% design submittal (which was based upon the "turn-key" concept) did not provide a meaningful opportunity to review the contract specifications intended for the General Civil Contract. This, coupled with the fact that many changes to the specifications have already been made, will result in a 90% contract specification which will bear only limited resemblance to the 60% submittal. In an effort to expedite the review process and avoid extensive modifi- cations to the contract documents after the 90% issue, I have requested Stone & Webster to provide an interim issue of the complete contract specifications. The interim issue will be limited to only the contract specification portion (including bidding instructions, bid schedule, etc.) and will not include the drawings. To the maximum extent possible it will include changes and comments provided to SWEC through October 14, 1986 and those "punch list" items reviewed on October 16, 1986 for which contract language is readily available and provided to Stone & Webster before October 22, 1986. Some changes, although acknowledged, may not be included until the 90% submittal. Attached is a letter from Stone & Webster outlining their revised schedule for the General Civil Contract review submittals. In summary: . The interim issue will be distributed on November 14, 1986. Some portions may be delayed until November 24. i The formal 90% issue will be distributed on December 15 and will include the design drawings. It is imperative that the Power Authority's and Bechtel's review of these documents be accomplished in a timely fashion. In order to incorporate comments from the interim submittal into the 90% submittal, it will be necessary to provide comments to Stone & Webster no later than December 1, 1986. Any comments not received by that date must be made Tater as comments on the 90% submittal. The objective of having an interim issue of the documents has three purposes: 1. To speed up the final review process by providing an opportunity to review the complete specification in advance of the 90% submittal. 6587/655/1 2. To issue a 90% document which truly represents a level of comple- tion equal to 90%. 3. To avoid extensive changes to the 90% documents. This objective can only be accomplished by timely review and construc- tive commenting on the part of all reviewers. It is imperative that we avoid the reoccurence of another review marathon similar to the Site Preparation Contract.

Possible contaminants include glacial silt and algae growth originating from penstock water, algae growth in the clean water sump, and brackish water from Kachemak Bay. As briefly discussed in the May 5, 1986 design meeting, four alternatives have been considered. 1. Alternate No. 1 Supply service water system with penstock water. This alternate would use the penstock tap as the primary source of water. Cooling systems would be designed to minimize glacial silt effects; and, algae and seawater would be eliminated from the systems. 735 Alternate No. 2 Provides service water with collection troughs and penstock water. i Collection troughs would provide service water to the clean water sump except during high tides when the collection troughs would be closed by valves. Service water would be provided during high tide periods from penstock taps. Algae growth would be controlled with chlorine and cooling systems would be designed to minimize glacial silt contamination. Alaska Power Authority Urey eee ve SG Alternate No. 3 Closed loop cooling system. Water for equipment cooling would be provided by clean and treated well water in a closed loop system. Heat would be exchanged with water from the clean water sump at a heat exchanger. Contaminants would be limited to a _ short heat exchanger loop then discharged to the tailrace. The heat exchanger would be designed for operating with the contaminants. Equipment cooling would be provided by treated clean water, circulated through the equipment with a circulation pump and rejecting heat at the heat exchanger. 4, Alternate No. 4 Provide a brackish water resistant cooling system. Piping, valves, instrumentation, and equipment cooling systems would have wetted parts made of brackish water resistant materials. Cooling system would be designed to minimize glacial silt effects and algae would be controlled with chlorine. Alternate No. 2, is not recommended because of reliability and environmental impact. Malfunctions in the system controlling penstock water/collection trough water or chemical feed, and algae from the penstock can contaminate the generator and turbine cooling systems. Requirements for treating algae in the sump, flushing algae and glacial silt from the cooling system and handling: chemicals make this Alternate more operator intensive and environmentally unsound. Alternate Nos. 1 and 4 are not recommended because of high cost without providing complete contamination control. Alternate No. 3 has the advantage of supplying clean water to purchased equipment and associated control systems. Contaminated water is limited to a small heat exchanger loop where high velocities, easy access for cleaning, and special materials eliminate the need for chemical treatment. Stone & Webster recommends that Alternate No. 3 be accepted by the_ Alaska Power Authority to reduce maintenance, fouling, and corrosion in the plant service water system.

Critikos Deputy Project Manager Attachment TC/JW ec: Mr. John Longacre, w/att DISCUSSION FOR THE OPERATING SYSTEMS DIVERSION TUNNEL HYDRAULIC SLIDE GATES BRADLEY LAKE HYDROELECTRIC PROJECT BACKGROUND The Alaska Power Authority requested that provisions be made at the Main Dam Diversion tunnel for unwatering the Bradley Lake reservoir. In response to this request, a flow control system is being provided within the tunnel to drain the reservoir in 45 days. The flow control system will consist of two hydraulic operated high head sluice gates and the gate operators and controls. The two gates are positioned within the tunnel in line with the flow. The upstream gate, which is normally open, acts as a guard or maintenance gate. The downstream gate, which is normally closed, is the main control gate. SYSTEM REQUIREMENTS The utmost requirements for the gate operating system are reliability and the ability for activating the system, especially after a major earthquake. To achieve these attributes requires a ready source of stored energy for gate operation and the ability to access the system for initiating its operation. Further enhancement to reliability can be realized by keeping the gate operating system simple and by providing operating flexibility. 2 Ano otter 4 ALTERNATIVES CONSIDERED Several energy sources are available for ennai danation, These include: (1) the electrical cable from the permanent housing facilities; (2) combustion engine-generators; (3) combustion engine-pump hydraulic power packs; (4) use of high pressure gas/oil accumulators; or (5) a combination of these energy sources. Of these, the most reliable energy sources are gas/oil accumulators. However, these can also be the most expensive. The least reliable is the electrical power cable, especially following a major earthquake event. Utilizing the above energy sources in singular or in combination we have considered the following gate operating systems. Alternative No. 1 This alternative is the simplest and lowest cost system. The gate operating equipment under this alternative would consist of two high volume high pressure motor/engine driven oil pumps, a sump tank and the associated piping, valves and controls. Because of its simplicity the system can be made very reliable and can be easily designed to resist high earthquake forces. However, the weakest link in this alternative is the energy source to the pumps, Two pump energy sources were considered: (1) electric energy from the "microwave" power cable; and (2) a combustion engine. The power cable source, however, has several limitations. The capacity of the cable is limited to supporting motor(s) up to a total of 15 horsepower. Also, the cable is vulnerable to damage or failure over its 20,000 feet of length. Combustion engines considered were diesel fuel or propane. Both fuel types offer good attributes as well as recognizable problem areas. Diesel fuel is considered safer than propane but is prone to "gelling", algae, and difficult ignition. Propane presents a safety problem but is a more dependable fuel source. We believe that both fuel sources are acceptable, recognizing their shortcomings. Because of the above described shortcomings and the absence of any means of energy storage, neither the cable nor the combustion engine(s) can be considered as a 100 percent reliable energy source. Therefore, the subsequently discussed alternatives are preferred since each provides a ready source of stored energy for gate operation. Alternative No. 2 This alternative would provide for a bank of 48 high pressure gas/oil accumulators vessels, piped as an integral system, to separately operate each of the two sluice gates. The system would also include a sump tank piping, valve and controls. The accumulators would consist of 16 oil filled and 32 gas filled vessels. All accumulators would be designed for a 2,000 psi working a aan oe > pressure and the gas would be nitrogen rather than air to eliminate moisture problems and reduce combustibility. This accumulator system would provide the stored energy needed to operate each ai through one full cycle, open-close or close-open, depending on gate, for a total of four strokes on a gate operating cylinder. Recharging the accumulator system would require the use of a low volume high pressure motor/engine driven oil pump. For this accumulator system, however, two such pumps are recommended for reliability. The one advantage of this alternative is that sufficient gas/oil stored energy is provided to operate both gates, each through one full cycle. However, this system has the following disadvantages: 1. System reliability. is poor. The failure of one vessel or connection pipe would disable operation of both gates due to loss of oil or gas pressure. 2. The 48 vessels required by the integral system, makes it difficult to provide the restraining support required against earthquake forces. a High cost. Alternative No. 3 This alternative would provide for two separate banks of high pressure gas/oil accumulators. Each bank would serve one gate and would have 8 oil vessels and 16 gas vessels. Sufficient energy is available within the bank to provide one full cycle of operation at the gate hydraulic cylinder, i.e., close-open for the upstream gate and bal bleep for the downstream gate. A motor/engine driven oil pump is needed for recharging the system; however, two pumps are recommended for reliability. The advantages provided by this alternative are: , Sufficient gas/oil stored energy is provided to operate each gate through one full cycle. as The separation of accumulator banks’ results’ in better reliability. In the event of failure of a vessel or pipe within a bank, the other bank is still available to operate its gate. a Provisions can be made to manually allow cross-over from one accumulator bank to the other as additional back-up. 4, Smaller number of accumulator vessels to supports against earthquake forces. The disadvantages for Alternative No. 3 are: 1s Difficult system restraining and support requirement against earthquake forces, 2. High cost. 4_9nQ_ TW 5 Alternative No. 4 This alternative is similar to Alternative No. 3. However, the number of gas/oil vessels available for energy storage is reduced to a total of 12 for each bank. Four vessels are provided for oil storage and 8 for gas. This reduced number of vessels provides only for half-cycle operation at each gate hydraulic cylinder; i.e., closing of the upstream gate and opening of the downstream gate. In our opinion, this operating mode represents the "fail safe" condition required from each of the two gates. Should a major earthquake occur, requiring dewatering of the reservoir, the downstream gate’ will be opened. Following reservoir drawdown or in the event the drawdown operation has to be stopped, the upstream "guard" gate is available for closure. The motor/engine driven oil pump requirements remain the same as for Alternative No. 3. Alternative No. 4 offers the same advantages as Alternative No. 3. Although the number of accumulator vessels has been reduced to allow only a half-cycle operation, this is not considered a disadvantage because the "fail safe" operation for each gate is still available. Design for earthquake is better because of smaller number of vessels. The cost for this system is also lower than that of Alternative No. 3. Alternative No. 5 Alternative No. 5 considers only one bank of 12 accumulator vessels for storing energy to operate the downstream gate through its opening eyele. Four of the vessels are used to store oil and 8 for gas. In addition, the system includes one high volume, high pressure motor/engine driven oil pump. This pump would be available to singularly operate the hydraulic cylinders of each gate; to operate the downstream gate in the event of accumulator loss; and, to recharge the accumulator system after use. We consider Alternative No. 5 the minimum acceptable "base" systen. COST Our approach in evaluating the cost of the previously described systems is based on cost-differentials. This approach allows for a better evaluation of each system and recognizes that "a system", regardless of selection, will have to be purchased for gate operation. Further, this approach is supported by the fact that several component parts of each system are common to all (i.e., feed and return pipes to the gate hydraulic cylinder; oil sump requirements; valving and piping within the system; operating controls). In determining the differential cost for each system, we have considered the major cost related equipment, which consists of the motor/engine driven pumps and/or the gas/oil accumulator vessels, based on the following cost values for these components. is Low volume, high pressure motor/engine driven oil pump at $3,000 each. ee High volume, high pressure motor/engine driven oil pump at $15,000 each. 3h High pressure (2000 psi) oil accumulator vessel at $6,000 each. 1 High pressure (2000 psi) nitrogen gas filled accumulator vessel at $1,000 each. Using the above cost values, each of the alternatives is ranked as follows: Alternative Alternative No. 1 - Two high volume oil pumps ($30,000) Alternative No. 2 - 16 oil vessels, 32 gas vessels plus two low volume oil pumps ($134,000) Alternative No. 3 - 16 oil vessels, 32 gas vessels plus two low volume oil pumps ($134,000) Differential Cost Base $104,000 $104,000 Alternative No. 4 - 8 oil vessels, 16 gas vessels plus two low volume oil pumps ($70,000) $ 40,000 Alternative No. 5 - 4 oil vessels, 8 gas vessels plus one high volume oil pump ($47,000) $ 17,000 REMOTE OPERATION To further enhance the reliability of the gate operating system, we recommend that means be provided at the power tunnel gate house to allow for the "manual-remote" operation of the diversion tunnel main control gate system. This "manual-remote" control capability will allow for gate operation in the event access to the Diversion Tunnel area is not available. This "manual-remote" is in addition to the manual-local control provided at the diversion tunnel area. It is estimated that installation of the "manual-remote" control system and its appurtenances would be about $10,000. CONCLUSIONS AND RECOMMENDATIONS Reliance of either the electric cable or of a propane/diesel fuel to provide power for the motor/engine driven oil pumps for operating the hydraulic slide gates at the Diverstion tunnel is not acceptable as the primary energy systems for gate operation. These energy sources can, at best, be considered only as secondary back-up systems. The reliability of the hydraulic slide gate operating system is greatly improved by the use of stored energy through an gas/oil accumulator vessel system. Fail-safe requirements for the downstream main control gate can best be met with an gas/oil gas accumulator system using a bank of 12 accumulator vessels. Fail-safe conditions for the upstream guard gate can be met either by the use of a bank of 12 accumulator vessels or by a high volume high pressure motor/engine driven oil pump. System reliability is further enhanced by providing totally separate operating systems for each gate, with provision for local and manual-remote operation of the main control gate. In consideration of the above, we recommend Alternative No. 5 as the most suitable installation for the project. This alternative would provide the reliability and flexibility required from system for operating the hydraulic slide gates at the Diversion Tunnel.

In partial fulfillment of our requirements, we submit our responses to comments on letters, SWEC/APA * 528, 530, 531, 612 and BEC-L-APA 120.? Vs Reference Letter SWEC/APA 528 - Construction Planning Comments provided by Bechtel; Mr. H. Elwif. a. Comment: Main Dam Diversion, Structural Design Criteria, Part B, Section 1.2.1, item f. The project schedule which has been in use for months shows the cof ferdam work starting in July, 1987. Prerequisite is completion of the diversion tunnel and allowing the lake to reach equilibrium. If the completion of the diversion tunnel becomes delayed increased inflows into Bradley Lake will result in increased times for the lake to reach equilibrium level. How long will it take for the Lake to reach equilibrium level if the diversion tunnel is finished in April, May, June or July? This information should be provided the CM. Response: The lake drawdown discharge rate can not exceed 1.5 times the average discharge of the Bradley River measured at Riffle Reach USGS Gauge after the completion of the diversion tunnel. The time required to reach equilibrium of the pond elevation during an average year is estimated as follows: Alaska Power Authority APA 782 Completion Date Duration April 1 35 days May 1 18 days June 1 10 days July 1 7 days Bb. Camment: Part B, section 1.2.1, Phase II, items a through i, also comment/response to SWEC/APA 530 comment item No. 1 and 2. Phase II describes completion of diversion tunnel gate shaft and features being done with bulkhead gates installed and removed. The Hydraulic Design Criteria, Section 2.0, page 3 indicates that a depth of water above 10' upstream of the gate might prevent its opening. This criteria indicates the gate will be removed by barge. If the lake level will rise more than 10' during this period these criteria have a conflict. Also contractor may not be able to lift gate. If not the construction scenario for the Phase II may not work. We are concerned that it may not be possible to lift gate under water level attained while performing Phase II work. Gate is about 13'x26'6". May need fixed wheel gate. Use of gate during operations also needs to be identified. If for some reason control and service gates would not close, it might be impossible to close bulkhead gate due to hydrostatic forces. Will O&M staff have a barge? Response: The Hydraulic Design Criteria divides the project into two phases, Phase I & Phase II. Phase I is the Site Preparation, which is scheduled to start July 1, 1986. Phase II is the Civil Construction Contract scheduled to start June 1, 1987. The bulkhead gates for the diversion tunnel have separate operating conditions for Phase I & II. The gates have been designed to close against flow and removed against an unbalanced head of 10.0 feet during Phase I. The gates will be installed and removed by a mobile crane located on bench whose elevation is 1096.0 During Phase II the bulkhead gates will be installed with the slide gates fully closed. The gates will be removed under a balanced head established by the refill valves located in the gate shaft. The bulkhead gates will be removed and installed by a barge when the pond elevation is above 1096.0. In the unlikely event that both the hydraulic control gate and the hydraulic guard gate can not be closed completely, the bulkhead gates could be installed under low flow (approx. 100 cfs) without excessive flow induced drawdown, 2. Reference Letter SWEC/APA 531 - Diversion Tunnel Design Comments provided by Bechtel, Mr. T. L. Oxman. a. Comment: In the October 8, 1985 study for lowering of Diversion tunnel and improvements to downstream Bradley River channel (SWEC Action Task #3), four diversion tunnel configurations were considered. Based on technical considerations, two schemes were studied further and the concept as presented February 27, 1986 was chosen as the preferred arrangement. The study indicated that this choice was made from a technical standpoint since from both the construction and cost standpoints, the two schemes were essentially equal. Because the chosen concept as currently developed now contains two hydraulically operated gates, it appears that the only advantage scheme 1 has over scheme 2 is the better use of rock formation to resist loads. From the constructability viewpoint, we feel the construction of an 18 foot diameter, 110 foot deep concrete lined shaft would be more difficult and therefore more costly than either an open cut excavation or an enlarged tunnel section at the downstream end of the Diversion Tunnel despite the need for additional restraints which may be required to improve the stability of an outlet control structure. With an outlet control arrangement, the entire Diversion Tunnel need not be exposed to the approximately 60 psi hydrostatic head (a disadvantage listed for scheme 2). The downstream end of the tunnel could be lined or the steel penstock arrangement could be retained with the gates at the downstream rather than the upstream end of the penstock. With either arrangement, it appears that the service gate may need to be a fixed wheel type as originally proposed in order to operate as a low level discharge under full reservoir head rather than a slide gate as currently shown. Response: The arrangement and design of the diversion tunnel during the Phase II work considered all these aspects mentioned in Bechtel's canments during the Action Task which was carried out from August through September 1985. The presently used scheme was based on the conclusion of that task. We feel that rock stresses and necessary reinforcement of a scheme with gates at the end of tunnel is unfavorable and offsets savings from the elimination of the shaft. Slide gates were used to allow a dry well, which was considered superior to the originally proposed wet well. b. Comment: The Fishwater Bypass is shown as a 28 inch diameter pipe. The pipe through the intake structure constructed in the Site Preparation Contract is shown as 26 inches. If a larger pipe is Aaaona fuNcL AULUUL ALLY APA (62 required to maintain flows, suggest that the Phase I contractor be requested to provide a 28 inch pipe to correspond with the current design requirements. Response: The preliminary calculations for sizing of the fish flow by-pass system concluded a 26-inch pipe would be adequate for 50 cfs. However, with the changes in the inlet conditions (36-inch diameter trash rack and other minor losses) the 26-inch pipe was determined to be undersized. The design of the inlet portal was essentially complete; a check was made to determine if the short section (approximately 65 feet) could be tolerated. After analysis it was concluded the short section of 26-inch pipe could be tolerated, thereby not requiring a design change. If a 28-inch pipe is substituted for the 26-inch pipe the shear strength of the section which passes through the pipe would be reduced by 10 percent. Therefore, further analysis for the concrete in the pipe zone would be required. Cc. Comment: also comment/response to SWEC/APA 530 by the State of Alaska, P. Hansen. A turbine generator was originally proposed for use with the hydraulic gate scheme. A diesel generator with battery charger might possibly be more cost effective and require less maintenance than the oil/air accumulator system currently shown. Response: Prior to October 8, 1985 a small turbine generator was being considered at the diversion tunnel exit. After further study it was determined that the turbine generator would not be cost effective. To provide permanent power at the dam site a single phase power cable would be provided, with a diesel engine-generator for back-up. For operation of the high pressure gates five alternatives were presented to APA for the gate operating system. Alternative 5 was selected. Reference SWEC/APA 679. 3. Reference Letter SWEC/APA 612 - Operating System for the Hydraulic Slide Gates Comments by the State/of. .AlaskajP.:\ ‘Hansen. a. Comment: My review of this item has produced the following canments: I do not believe that any of the 5 alternatives listed are satisfactory. This is caused by the nature of the assumptions made concerning the situation likely to be experienced following a major earthquake. Little consideration seems to be given to the fact that the design criteria is the ability to empty the reservoir in 45 days. Alaska rower autnorlty APA [82 This time frame greatly reduces the need for complicated, expensive, and in real life, not very dependable, redundant, automatic and/or remotely operated systems. It would seem more than likely that even in the event of a very major earthquake, access could be secured to the gate area by helicopter in less than one day. It appears that Alternative 5, as preferred by SWEC, is unnecessarily complicated and expensive without providing the desired reliability. I can not agree with the idea that in the event of a major earthquake, which breaks the powerline to the gate house in addition to making the gate house inaccessible, we can rely on a remotely controlled system using 2,000 psi pressure cylinders. Alternative 5 does not address: 1) What powers the control system when the power line is down? 2) How well does the remotely operated hydraulic system perform if we try to operate it after the power line has been down for a couple of days and the building temperature has dropped to ambient temperature? 3) How does a major earthquake affect a system with heavy high pressure cylinders and high pressure piping? Response: 1) In the event of major earthquake or other event causing structural damage in the dam or spillway, the first few hours are most critical. After the first few feet of static head is removed, the stability of the structure is greatly improved by reestablishing freeboard. In the event of major main dam settlement or freeboard loss drawdown of the reservoir will be necessary. 2) We wish to clarify the 45 day criteria, it is not a maximum time limit. At maximum pond elevation (El 1180.0) it represents a safe drawdown duration utilizing the maximum drawdown rate (ft/day). 3) Controls are powered by a backup battery system. 4) Hydraulic operating system will be heat-taped with the power being provided by the diesel engine generator at the power tunnel gate house, 5) Hydraulic operating system will be design for a .75g earthquake. If a larger magnitude earthquake is experienced the diesel engine/pump system will be activated. 6) There should be no maintenance requirements for the gas/oil accumulator. b. Comment: I believe that the following solution would be simpler, cheaper, and most likely, also more reliable: Alaska Power Authority APA 782 1) Reduce the power/energy need by providing a pulley/ counter-weight system for each slide gate. Basically, only friction forces will be left to deal with. 2) Provide power for the resulting lower pressure/higher volume hydraulic pumps through a power line. Use a few smaller pumps limited to 3-5 hp and operated in parallel for reliability and for limitation of power needed. 3) Provide a small, air-cooled back-up diesel generator (10-15 kW) for use in case of a powerline failure. 4) Provide a small gasoline driven emergency generator sized to operate one pump only, in addition to emergency lighting. 5) Provide a manually operated hydraulic pump for emergency use. Besides costing money to design, construct, heat, and maintain, what is the purpose of the 30'x20' building shown over the gate shaft? The equipment needed to raise/lower the gates could easily be housed in the gate shaft itself if the above mentioned solution was used. Response: 1) Friction accounts for 96% of the forces experienced by the gate lifting mechanism. 2) A diesel engine - generator will be provided at the power tunnel gate house. 3) We have received directives from APA not to use gasoline or LPG as a fuel source. 4) A manual pump will deliver approximately .75 cubic inches per stroke. The volume of the hydraulic oil is approximately 120 gals (27,600 cubic inches). Therefore the number of strokes for fully opening the gates would be approximately 37,000 strokes, with 30 strokes per minute the gate will take over 20 hours to open. 5) The arrangement of the gate shaft allows a direct lift of the large hydraulic equipment (gates & hydraulic cylinder). If the operating equipment is installed in the shaft it would have to be removed if the gate leaf or the hydraulic cylinder is removed. Comments by the ‘State'of Alaska; MMSE? Morris. 6. Comment: Is there a requirement to dewater the Bradley Lake reservoir below the natural water level? If so, how long a period can it take? The design to take 45 days to dewater the system does not seem to correlate to an emergency lowering of a reservoir level. Alaska Power Authority APA 782 If the time to start lowering the reservoir is not critical, why not rely on controls driven by on-site generation. What is the cost of flying in a replacement unit compared to the cost of the other proposals? If time is important, have gravity operated systems been considered? A local generator or the "microwave" power cable could be used for the electric operator to place the gravity weight in position for a half cycle operation. Unfortunately, I am not a mechanical engineer and cannot be sure of reliable "non-operation" during an earthquake. Any proposals for a half cycle trip as above or in alternatives 4 and 5 do not provide for an immediate recovery from a misoperation. What are the consequences or costs involved so that the half cycle operation proposal can be compared to the full cycle proposal? Response: 1) See response to P. Hansen comments. 2) The closing cycle can be provided by the following: ° Engine generator powering the small pump to recharge the bank. ° Diesel engine/pump. ° Portable engine-generator powering the small pump _ to recharge the bank. 4, Reference Letter *BEC=L-APA=120-D%version Tunnel Hydraulic Slide Gates Comment: In our review comments concerning the Diversion Tunnel gate shaft and fish bypass (BANC/L/APA/100 dated May 8, 1986), we suggested the possibility of using a diesel generator as an energy source for operation of the subject gates. After reviewing the referenced transmittal, we have concluded that the use of a diesel generator provides adequate reliability for operation of the gates. The diesel engine can be periodically exercised from a remote location and would not require maintenance or inspection any more often than a gas/oil accumulator system. In the event that unwatering of the Bradley Lake Reservoir is necessitated due to a major earthquake, an operator would undoubtedly be dispatched to the dam to verify that the gate was in fact open. In the unlikely event the equipment malfunctioned and the gate had not opened, the operator could open the gate manually. Alaska Power Authority AFA [02 Based on a 45-day draining period, the additional time required for repair of the system or manual operation of the gate would be insignificant.
