U Bolt allowable loads will be based on finite element analyses using the criteria for bolts given in ASME Code Case 1644-4.

Rod hangers are generally single acting vertical supports, in the upward direction they are susceptible to an early buckling condition. Capacities therefore, in the upward direction are minimal. Consideration of this condition will be made within the evaluations of hangers. Capacities in the downward direction will continue to be obtained from applicable load capacity data sheets.

For component standard supports which do not have certified LCDS, the catalog allowable load at the time of manufacture will be prorated for the various loading conditions by the same factor used for the same component with a LCDS. The prorated load shall serve as the maximum load for the given loading condition.

Supports Fabricated from Non Catalog Items The stress limits for supports fabricated from non-catalog items shall be based on allowable stresses from ASME III, ANSI or ASTM material used. If the material is not known, it is assumed to be A-36 carbon steel.

' - "CONTROL ROOM HVAC -.

CONTROL ROOM EMERGENCY AIR TREATMENT SYSTEM (CREATS) AND EMERGENCY- COOLING SYSTEM MODIFICATION P & ID."

WITHIN THIS PACKAGE D-O1

Sequence of operation - CREATS, PCR 2000-0024 1.0 Modes of Operation:

1.1 NORMAL

The existing Control Room HVAC system will provide heating, cooling, and fresh air to the Control Room.

1.2 EMERGENCY

Upon receipt of a EMERGENCY signal (see section 3.2.1) the Control Room Emergency Zone (CREZ) will be isolated, and each new 100% capacity train of Control Room Emergency Air Treatment System (CREATS) will filter and recirculate 6000 CFM (+/-10%) of Control Room air. The CREATS fans will be 1E powered and will start from a manual pushbutton isolation signal, toxic gas signal, radiation monitor signal, Safety Injection (SI) signal, or from the manual hand switch for the fan. The new trains of CREATS will not have a pressurized mode of operation, but the CREATS system duct and damper design preserved the capability of adding this mode of operation in the future, if required. The existing CREATS filter and fan will be disconnected and may be removed or abandoned in place as part of the modification.

1.3 EMERGENCY HEATING/COOLING:

Two new 100% capacity Emergency Heating/Cooling Systems will automatically heat or cool the Control Room, as needed, whenever the associated CREATS fan is in operation. Emergency Heating/Cooling Systems will be 1 E powered, and will strip upon SI.

1.4 PURGE

This mode is the same as the NORMAL mode of operation, except that the maximum amount of fresh air and exhaust air will be provided. This mode will be over-ridden by an EMERGENCY signal which isolates the CREZ and trips the NORMAL mode fans. However, with local operator action a purge flow can also be established from a different outside air source (Relay Room Annex) while in the EMERGENCY mode of operation.

2.0 Arrangement of Controls & Indication:

Control panels on the Auxiliary Benchboard (ABB) where the existing CREATS controls are located will be reconfigured. The new controls arrangement is shown on the attached ABB layout drawings.

2.1 NORMAL 2.1.1 Similar to the existing arrangement; the Auxiliary Benchboard (ABB) will have a pistol-grip switch for the Control Room NORMAL supply & return fans, and red & green lights indicating fan status.

2.2 EMERGENCY 2.2.1 At the ABB two pushbuttons will provide the manual CREATS actuation feature. Each pushbutton will start ONE train of CREATS fan, and close ALL of the Control Room Emergency Zone (CREZ) isolation dampers.

2.2.2 At the ABB, each train will have a pushbutton to provide isolation reset for that train. To re-open the Page 1 of 5

isolation dampers both reset pushbuttons must be pushed (independently or simultaneously).

2.2.3 Lights on the ABB will indicate position of isolation dampers in each of the three flowpaths isolated by dampers AKDO2, AKDO3, AKD21, AKD22, AKD23, AKD24. Lights will be controlled by end switches installed on each damper. To minimize the number of lights on the ABB a single green light for each damper will indicate when the associated damper is closed.

2.2.4 At the ABB two white lights will indicate high temperature sensed at either train's charcoal filter inlet and outlet (TAH-5153A/B and TAH-5154A/B). Two other white lights will indicate a low flow condition from either CREATS fan (FS-5150A & FS-5150B).

2.2.5 At the ABB the CREATS fans AKF1OA & B will each have a manual switch (PS/STOP/AUTO/START) with a green and a red light indicating fan status. A red & a green light will also indicate status of the associated fan's discharge damper.

2.2.6 Defeat of an isolation signal, if required, will be performed at the associated monitor's control panel (toxic gas monitors on the Turbine deck, or radiation monitors R-45 & R-46 at the RMS rack in the Control Room). There will be no switch for defeat of the isolation signal from SI or the manual isolation pushbuttons.

2.2.7 Area radiation monitor R-1 will provide indication only. Alarm of R-1 will no longer provide an EMERGENCY signal, CREATS fan start, isolation damper closure, or override of the PURGE mode.

2.3 EMERGENCY HEATING/COOLING 2.3.1 At the ABB two pushbuttons will allow reset of power to the Emergency Cooling and the electric heaters, following reset of the SI signal. This prevents automatically loading equipment on the D/Gs when SI is reset.

2.3.2 Emergency Heating/Cooling Systems will be controlled by thermostats located in the Control Room. Since it employs the airflow from the CREATS fan, a low flow signal (FS-5150A & FS-51503B) indicates loss of both the CREATS filtration and the Emergency Heating/Cooling functions for that train.

2.4 PURGE 2.4.1 At the ABB a switch labeled 'NormaVPurge" will initiate the purge mode of operation.

3.0 Alarms & Operator Interface:

3.1 NORMAL 3.1.1 The pistol-grip switch and red/green status lights are self explanatory.

3.2 EMERGENCY 3.2.1 An EMERGENCY signal originates from any of the following circuits, each of which has two trains: SI, radiation monitors (R-45 & R-46, not R-1), toxic gas monitors, or manual isolation. An EMERGENCY signal will:

1. Close isolation dampers AKDO2, AKDO3, AKD21, AKD22, AKD23, & AKD24.

2. Start the associated train of CREATS fan, AKF1OA or B (except radiation monitors, which will start both CREATS fans)

3. Trip the normal CR HVAC supply, return, and lavatory fans and heating elements (AKFO3, Page 2.. of 5

AKFO8, AKFO9, & AKA03).

4. Energize Main Control Board (MCB) annunciator E-1 1; "Control Room HVAC Isolation".

3.2.2 One or both CREATS fans may be secured in the pull stop position at the discretion of the Control Room operator any time after the fans automatically start.

3.2.3 Existing damper AKDO2 and new dampers AKDO3, AKD21, AKD22, AKD23 & AKD24 are all normally open and will close upon any EMERGENCY signal. All of these dampers will fail closed upon loss of power or instrument air, as applicable, and green lights for each flow path will operate as described in section 2.2.3.

3.2.4 Dampers AKD35A & AKD35B are back draft dampers that are normally closed, their motor actuators will allow the damper to open when the associated fan receives a start signal, or upon loss of power to the actuator.

3.2.5 If FS-515iA or FS-5150B indicates low flow when it's associated CREATS fan has a start signal, then the white low flow light at the ABB, and the new Main Control Board (MCB) alarm E-8 will be energized, to alert operators to the potential loss of a SR function. A 10 second time delay after the fan start signal will allow flow to be established before this alarm is enabled.

3.2.6 If there is no EMERGENCY signal (as defined in 3.2.1), and any Si signal has been reset, then pressing both Control Room Isolation reset pushbuttons will:

1. Open the isolation dampers; AKDO2, AKDO3, AKD21, AKD22, AKD23, & AKD24

2. Clear MCB alarm annunciator E-1 1; "Control Room HVAC Isolation"

3. Secure both trains of CREATS in auto

4. Allow re-start of normal HVAC; AKFO3, AKF08, AKFO9, & AKA03 3.2.7 One or both CREATS fans may be manually started at any time by taking the fan switch to the 'START' position, in which case Control Room isolation will not occur. However, new Main Control Board (MCB) alarm E-8 will be energized to indicate the off-normal condition, direct the logging of charcoal filter run-time, and prevent redundant heating/cooling.

3.2.8 In addition to energizing ABB indicating lights, an alarm from temperature switches TAH-5153A/B or TAH-5154A/B will alarm MCB annunciator K-31 in the Control Room.

3.2.9 The outside air damper control valve for use in the EMERGENCY mode (located in the Control Room Kitchen) will no longer function, and will be removed or abandoned in place. Except for room thermostats, all Control Room HVAC system controls, including CREATS controls, will be located on the ABB.

3.3 EMERGENCY HEATING/COOLING 3.3.1 Operator interface with the Emergency Heating/Cooling system is limited to thermostats in the Control Room, and alarms that indicate a problem with the system. These features are described in section 4.3.

3.4 PURGE 3.4.1 The outside air damper control valve for use in the fire mode (located in the Control Room Kitchen) will no longer have a function and will be removed or abandoned in place.

3.4.2 Switching to the PURGE mode will energize the new MCB alarm E-8 to make operators aware of the off-normal system alignment.

Page 3 of 5

4.0 Automatic Controls / Interlocks:

4.1 NORMAL 4.1.1 Temperature control will continue to be automatic via thermostats & zone dampers.

4.1.2 Heater staging and instrument air pressure interlock of the electric heaters will be re-configured to improve temperature control and ensure a fail-safe condition upon loss of IA. Permissive flow switch FS-5154 will be maintained to ensure electric heaters are not energized without airflow.

4.2 EMERGENCY 4.2.1 Each train of Emergency Heating/Cooling System will strip upon an SI signal in the associated SI train.

Re-energizing these components will require SI reset and subsequent Emergency Heating/Cooling reset at the ABB.

4.2.2 If carbon filter temperature switches TAH-5153A/B or TAH-5154A/B sense a high temperature then the associated CREATS fan AKF1 OA/B will trip, the associated CREATS discharge damper AKD35A/B will close, an ABB indicating light will be energized, and MCB annunciator K-31 will alarm.

4.3 EMERGENCY HEATING/COOLING 4.3.1 Each train of Emergency Heating/Cooling system will strip upon an SI signal in the associated SI train.

Re-energizing these components will require SI reset and subsequent Emergency Heating/Cooling reset at the ABB.

4.3.2 A low or high refrigerant pressure will trip the Emergency Cooling System compressor(s) & condenser cooling fan, and energize the new MCB alarm E-8. The high & low pressure alarms will be operable even when Emergency Heating/Cooling is secured, in order to indicate a potential refrigerant leak and inoperability of the equipment.

4.3.3 Each Emergency Heating/Cooling System train will have a thermostat that controls heating & cooling to maintain suitable room temperature. An Emergency Heating/Cooling System will be energized only if:

1. Associated CREATS fan is running,

2. Low flow switch FS-51 5OA/B is not in alarm

3. High and low refrigerant pressure switches are not in alarm (interlock for cooling only)

4. No SI signal is present (SI must reset at MCB and at the new ABB SI reset pushbuttons)

5. Necessary to satisfy room thermostat TC-51 5OA/B.

4.4 PURGE 4.4.1 The PURGE mode of operation will open existing dampers AKDO1 & AKDO4 to their limit stops, providing up to 2000 CFM of fresh air and an equal amount exhaust air from the Control Room.

4.4.2 The function of the PURGE mode is lost when an EMERGENCY signal isolates the CREZ, trips the NORMAL fans, and starts CREATS. A manually initiated alternative is described in section 5.4.2.

5.0 Manual Features:

5.1 NORMAL Page 4 of 5

5.1.1 The existing switch located on column F12, on the Turbine deck outside the Control Room, will be disabled. This is because of concern for a switch located in a Non-vital area controlling an ESF ventilation system, and because it's use during a postulated Control Room fire would not conform with the fire response procedures that normally trip equipment at it's associated breaker, instead of a control switch.

5.2 EMERGENCY 5.2.1 Upon high temperature sensed at TAH-51 53A/B or TAH-51 54A/B a fire response procedure will direct operators to verify a high temperature and, if required, connect a fire hose to the charcoal filters deluge system header in order to douse the fire.

5.2.2 Dampers AKD30A/B and AKD31A/B will be low leakage dampers that can be secured in the closed position. Along with their associated discharge dampers AKD34A/B & AKD35A/B they will provide an isolation boundary that allows opening of the filter systems' pressure boundary without compromising integrity of the Control Room Emergency Zone.

5.2.3 The need for the manual heat control currently used in the EMERGENCY mode of operation will be eliminated.

5.3 EMERGENCY HEATING/COOLING 5.3.1 Emergency Heating/Cooling can be manually actuated, without closing the CREZ isolation dampers, by starting a CREATS fan, otherwise Emergency Heating/Cooling have no manual features.

5.4 PURGE 5.4.1 The PURGE mode will be manually actuated via a switch on the ABB and will be over-ridden by any EMERGENCY signal.

5.4.2 In the EMERGENCY mode of operation an alternate source of outside air can be provided by the local operator action of removing the blind flange(s) adjacent to dampers AKD32A/B and opening the door(s) of the Relay Room Annex.

Overview of Electrical Information

1. Single Line drawing of Power cables for new 480 volt MCCs and equipment A marked-up copy of 33013-2539 showing where new MCC's N and P will be connected to the rest of the 480 volt system is included. Two one-line sketches labeled A480 and B480, show one line and cable routing from MCC's C and D to new MCC's N and P, and to new loads.

2. Tray Drawings showing separations for 480 volt power Circuit schedules C5618 and C5619 show cable routing for the A and B train 480 volt power cables respectively. These circuit schedules demonstrate that no trays are shared. Drawing 33013-3002 sheet 2 have been issued for construction, they show the cable trays utilized in the battery rooms and demonstrate the separation maintained between the two trains. This drawing also shows equipment location of MCCs, transformers, and panels in Relay Room Annex, and displays that all 480 volt cable in the Relay Room and Annex is routed in conduit.

3. Diesel Generator Loading Analysis, including new Fan acceleration Preliminary evaluation of the new loads versus existing diesel generator loading calculations indicates that there is adequate margin for the addition of the new CREATS emergency fans.

New CREATS heating units and cooling units will trip on SI, so have not been included in' evaluations against short term diesel loading. For long term operation, preliminary evaluation indicates that there is adequate margin for adding the new heating and cooling system after initial SI loads have been reduced. We are awaiting speed torque curves from the fan vendor, to demonstrate that acceleration time and loading will be appropriate to allow loading of the fans on the diesels at SI time = 0.

4. Damper Isolation Actuators Th actuators on the isolation dampers are all power to open, with spring return close on loss of power. Included is a cutsheet for the SURE 100 electric actuator Our final configuration is awaiting input from the vendor as to mounting which will determine clockwise or counterclockwise rotation, and wiring connections will be made for the configuration that ensures that the damper will close to the isolation position for all failure modes. Likewise, solenoids for the air operated dampers will close the damper when de-energized and on loss of air. Elementary wiring diagrams 10905-0825 sheets A and B illustrate that the damper actuators (MO/AKD21 thru 24, and solenoids 14922S and 14930S) are all de-energized by the R81AX and R81BX relays. The breakers supplying these devices will be sized to provide adequate capacity to preclude unnecessary trips while providing adequate protection to the cable. Specific calculations and formal calculations demonstrating these points will be prepared as part of the modification process and will be completed before installation.

5. Elementary wiring diagrams for the main isolation logic and controls for the main CREATS equipment are attached. These elementaries reflect the operation of the equipment in accordance with the Sequence of Operations document and auxiliary benchboard layout drawings that are also included with this submittal.

I Pat: 5 SAFETY FIRST Pay soflo Inthe maintenance and operation of mechanical equipment, sAFmEY isthe basic factor which must be considered at all times. Through the use of the proper clothes, tools and methods of handling, serious accidents causing injury to you or your fellow worker can be prevented.

Throughout this manual are listed anumber of safety precautions. Study them carefully and follow them; also insist upon those working for you do the same. Remember, an accident isusually caused by someone's carelessness, neglect or oversight.

A To prevent ignition of hazardous atmospheres, do not remove actuator cover while circuits are live.

CAUTION CAUTION ]

A CAUTION Loaded spring inside actuator. Do not attempt to repair actuator below top gear plate, unless properly trained on repair methods.

A CAUTION 1

j INSTALLATION

1. Operate device manually before installing actuator and orient into the same position as actuator spring would drive.

2. It device is equipped with mechanical position stops they should be removed, but care should be taken not to damage or remove necessary parts.

3. Care should be taken to maintain proper alignment between the actuator and device shaft. If actuator is not in correct alignment with the device shaft, repeat operation number one (1) with correction as required.

4. Mount the actuator to the device. Tighten all bolts and nuts evenly, taking care to center the actuator on the drive shaft or stem. It is often a-good idea to cycle the actuator while the mounting bolts are somewhat loose. This will allow the unit to center itself.

5. Remove the cover bolts located about the control cover flange of the actuator.

6. Wire per diagram, or if actuator is of special design, wiring diagram is included with unit. Use ,.18AWG stranded wire or better, for field hook-up.

7. Special Note: All Surepowr models can be factory built for clockwise or counter-clockwise spring drive rotation, as viewed from top of actuator. Extra care is advised to insure correct wiring diagram/actuator use.

8. Run unit from one extreme to the other several times.

9. Cam adjustments (if required), as follows: CLAMPIGC >VCTS;rEWS To set open travel by adjusting cams: 5 M/

(a) Loosen clamping screw on cam "E" to give the cam a finger tight grip on shaft, rotate cam clockwise away from switch.

(b) Manually operate device to the proper "open" position. CAM 'E-(c) Rotate cam 'E" counter-clockwise against switch roller until switch swum 0 just "breaks". You should hear alight clicking.

(d) Tighten clamping screw. If travel is not correct, repeat steps (a).

(b) and (c), or use the micro-adjustment cam.

To set close travel by adjusting stop screw and cam:

(a) Loosen clamping screw on cam "D" to give the cam a finger tight CAWC UIACRO ADJJST grip on shaft, rotate cam counter-clockwise away from the switch.

(b) With power off, adjust shaft close position with end of travel stop on outside bottom of actuator.

(c) Rotate cam VD" clockwise against switch roller until switch just "breaks". You should hear a light clicking.

(d) Tighten clamping screw. If travel is not correct, repeat steps (a), (b) and (c). or use the micro-adjustment cam.

FORM NO. 6005 12193

A t To prevent ignition of hazardous atmospheres, do not remove actuator A cover while circuits are live.

CAUTION CAUTION Note: In the event that the above procedure does not give the necessary travel control, the micro-adjustment cam has to be repositioned as follows: EGSDP-9nOi1-144 To set travel by adjusting switch plate: Revision IAuahrnent:I 0

Part:SI (a) Loosen pivot and micro-adjustment screws. Pg 6 f s (b)In the event of actuator under travel, rotate micro-adjustment cam to swing switch outward from the cam post.

(C)Inthe event of actuator over-travel, swing switch into cam post.

(d)Tighten pivot and micro-adjustment screws.

Note:Adjusting the switch plate will move the "motorside"endof the travelposition only. The spring return side'position is controlled by the travel stop on the bottom of the actuator.

10. Replace cover and tighten all flange bolts.

11. Unit is now ready for automatic operation.

Attauchment: 1 Pan:

OPERATION: Page 8 - of 10 POWER ON: The electric motor drives the gear train, which in turn winds the spring and turns the device. An internal limit switch de-energizes the motor and energizes the brake, which holds the return spring and device in position.

POWER OFF: When the current is interrupted by either a control signal or a power failure, the return spring drives the device to its original position.

Note: It is recommended that the actuatorbe driven electrically in both directions for normal operation to prolong cycle life.

MAINTENANCE Gear train is permanently lubricated at the factory for the average life of the actuator. Brake gap is set at the factory. No further attention is required.

THERMAL OVERLOAD The internal thermal overload switch de-energizes the motor and prevents overheating of the motor windings due to excessive operation, stalling or high ambient temperatures.

DUTY CYCLE The maximum duty-cycle to be expected without interruption by thermal cut-off at an ambient temperature of 150 Fis 25%. (3 'OFF" times for every 1 "ON' time), for the 10 second design, and 50%, (1 "OFF" time for every 1 "ON time), for the 30 second design.

STORAGE The Surepowr actuator must be stored in a clean, dry, temperature controlled building which is protected from the weather.

Precautions shall be taken to prevent condensation inside or outside the actuator. If there is insufficient external temperature and humidity control, internal heaters must be installed and energized to protect the unit against condensation from extreme temperature variations. The actuators shall be stored off the floor on suitable pallets and must be covered with an unsealed dust protector allowing side and bottom ventilation.

TROUBLESHOOTING Note: Mostactuatorproblems occur due to incorrect cam/travel limit switch setting, or the use of an external travel stop on the device that the actuator is operating.

Problem 1: Actuator is receiving electric power but the motor does not respond.

Instructions: la. Check actuator nameplate to insure correct model, voltage type and sprng return direction.

- lb. Check all wiring against installation wiring diagram.

Uc. Measure live voltage to insure that actuator isreceiving full rated voltage.

1d.Check cam/travel limit switch position to insure that motor control switch isnot made and that the actuator is within its normal open-close rotation limits. This check can be made using a volt meter connected between one side of the incoming line (common) and one leg of the motor or capacitor. This check should show power between common and one leg only. Power at the common and both legs or no power at all, would indicate cam and or wiring adjustment(s) are required.

Problem 2: Actuator is receiving electric power but the motor only hums.

Instructions: 2a. Perform steps la through Id listed above.

2b. Check to insure brake is completely disengaged when power is applied.

Problem 3: Actuator runs but operation is erratic.

Instructions: 3a. Perform steps la through 1d listed above.

3b. Check ambient temperature. Standard Surepowr actuators have a maximum ambient operating temperature rating of 150'F.

3c. Check duty cycle (frequency of operation). See above for details.

3d. Check to insure actuator is not running into a continuous stall condition.

Problem 4: Motor runs continuously in spring return direction after actuator output shaft has stopped.

Instructions: 4a. Adjust spring return side travel cam/switch so that the cam trips the switch before shaft stops motion.

Note: Al Surepowr actuators are manufactured with built-in thermal overload motor protectors.

Should any of the above cause the protector to open, it will automatically reset when the motor temperature is lowered to asafe level.

Reference:

Sure 100 with manual override.

At your request, I am forwarding drawing 90-857 showing the SurelO0 with a manual override wormgear-operator.

The arrangemem shown allows the customer to manually override the Sure 100 during powcr failure. The actuator can be manually overriden to any position between fully open and fully closed, and it will remain in that position until manually returned to fully closed. In other words, the actuator will spring return to the manual override position, not to its fail-safe position.

As an added note, the manual override will function only if the actuator is mouited to the valve Without the spring in the Surel00, the manual override can be used to open the valve, not to' close it. If your customer wants a manual override for contol while the actuator is off of the valve for maintenance, then this arrangement will not work.

If you have any additional questions, please let me know.

Attachment 2 Justification of Locked Rotor Failed Fuel Assumption

LOCKED ROTOR FUEL FAILURE EVALUATION BACKGROUND The Westinghouse accident analyse for the locked rotor event, assumes that fuel failure occurs at the onset of DNB, even though the rods may be in a film boring condition for a very short period of time. In fact, for rods going into DNB for a short duration, fuel failure may not occur. Also, alternative methods of evaluation, such as utilizing the fuel rod enthalpy as a measure of fuel failure, would reduce the conservatism inherent in the use of the DNB or Critical Power Ratio methods.

The application of the Westinghouse locked rotor DNB analysis, to a 2-loop plant, tends to result in high fuel failure, e.g., >70%. A review of non-Westinghouse locked rotor analyses, for other 2-loop plants (Kewaunee and Prairie Island) found that relatively small amounts of fuel failure are predicted.

Rather than base Ginna's locked rotor dose analysis on the results of a conventional DNB-based fuel failure analysis, Ginna's assumed percent failed fuel will be conservatively based on the failed fuel results of other similar plants.

The factors that may lead to DNB (fuel failure), following a locked rotor, event include:

• reduced reactor coolant flow rate

• increased power production in fuel The following data describes the reduction in core cooling as a result of a locked rotor, the overall NSSS power and the distribution of power within the core.

• Only 2-loop NSSS - The selection of only 2 -loop plants provides data that reflects a loss of 50% of the total reactor coolant flow.

• NSSS Power - The power produced by the plant. Increased fuel power density may result in failed fuel following a locked rotor event.

• F. limit - The hot channel factor is the ratio of the maximum rod linear power density to the average linear power density. Higher powered rods are more likely to fail following a reduction in reactor coolant flow.

• FAH limit - The radial peaking factor is the ratio of power produced by the highest powered (fresh fuel) rod to the average rod. Higher powered rods are more likely to fail following a reduction in reactor coolant flow.

DATA The data, in Table 1, was obtained by searching publically available documents, through the NRC's ADAMS document system. All 2-loop Westinghouse NSSS plants (Ginna, Point Beach, Prairie Island and Kewaunee) were searched. Search terms included: Reload Safety Evaluation, RSE, locked rotor, COLR, NDR, Nuclear Design Report, and failed fuel.

Inspection of the data shows the following:

• Power Level -The plants have similar power levels (Kewaunee and Prairie Island produce 8.5% more power than Ginna).

• FAH - The FAH limit assumed by Kewaunee is constant. As such there is no observable trend with respect to failed fuel. Ginna's FAH limit is in the middle of the range: about 3% higher than Kewaunee and about 1% less than Point Beach.

• Fq - The Fq limit assumed by Kewaunee shows a decreasing trend. Ginna's Fq limit is outside the range: about 9% higher than the Kewaunee Cycle 25 value and about 2% higher than Point Beach's.

RESULTS Two-loop core power parameters were compared. The results of the comparison shown that the Ginna data is bounded by some of the values and exceeds others. However, in all cases, the values are comparable. The percent failed fuel ranges from 40 percent (Kewaunee Cy 23), to 15.5 percent (Point Beach Cy 21).

The Kewaunee data shows a trend of decreasing failed fuel (40% for Cy 23, 19.3% for Cy 25).

GINNA FAILED FUEL ASSUMPTION The most conservative application of this failed fuel data is to use the highest observed value. In addition, margin is added for additional conservatism. The percent failed fuel proposed for the Ginna locked rotor dose analysis is 50%.

This is based on the highest reported value of 40% (Kewaunee Cycle 23) with an arbitrary 25% conservatism added.
