EC 424080 Revision 3 Page 2 of 19 Revision 2:

There were two major revisions in rev 2 of this EVAL EC:

1) The components within 2A EDG room were re-evaluated to determine if elevated temperatures could be tolerated during a 24-hr emergency operation. This resulted in the most limiting component(s) that are installed in 2A EDG Room having their maximum allowable temperature increase from 131°F to 139°F.

2) As a result of increasing the allowable 2A EDG room temperature from 131°F to 139°F, MPR performed additional analysis to determine what various outside ambient air temperatures would result in 2A EDG room reaching 139°F at the conclusion of a 24-hour emergency run.

A.3 Problem Statement This EVAL EC is in response to 2A EDG Room Ventilation issue summarized below and documented in NCR 2499589.

On January 2, 2024, during planned testing of 2A Emergency Diesel Generator (EDG), the 2A EDG room temperature increased from 81° Fahrenheit to 106° Fahrenheit with no clear signs of stabilizing. The decision was made to declare 2A EDG Inoperable because trending indicated room temperature would potentially exceed the 120° Fahrenheit maximum design basis room temperature within the 7-day mission time. The cause of the elevated room temperature was a failed room temperature controller 2VDTT7500 (damper controller for 2A1 VD Fan) with the 2A2 Emergency Diesel Generator Room Ventilation (VD) Fan removed from service for preventative maintenance. The failed room temperature controller prevented the outside and return air dampers from operating correctly. The 2A1 temperature controller 2VDTT7500 was replaced on January 3, 2024, after it was discovered failed to return the 2A1 train to fully functional status. The 2A2 fan motor was subsequently replaced with a new motor on February 6th, 2024 to return the 2A2 train to fully functional status.

Note: Throughout this document the term "recirculation mode" and "once-through ventilation mode" will be used. These modes of operation are defined as follows:

The emergency outside air supply dampers and the return air dampers design function is to modulate to maintain a EDG room temperature of 85 degrees. "Recirculation mode" of operation is defined as the emergency outside air supply dampers in the fully closed position and the return air dampers in the fully open position. "Once-through ventilation mode" is defined as the emergency outside air supply dampers fully open and the return air dampers fully closed.

Summary of normal 2A EDG Room ventilation operation:

The 2A EDG room is equipped with two VD Fans (2A1 and 2A2) that provide emergency ventilation for the 2A diesel generator. Each fan is 30 HP 600 VAC which develops 58,500 CFM +/- 30%. These fans are safety related and are located in the "Emergency" portion of the VD system to provide a suitable environment for diesel operation.

The two VD emergency fans will essentially start anytime the diesel receives a start signal to supply adequate ventilation during diesel generator operation. The fans are automatically stopped by a signal from the fire detection system in the event of a fire in the diesel building. The fans will also start on a Blackout or LOCA signal, which overrides any fire protection system signal that may be present.

When the outside air temperature is less than or equal to 89°F, the diesel generator is operable if one diesel generator fan is capable of operating when the diesel operates.

EC 424080 Revision 3 Page 4 of 19 Furthermore, when the outside air temperature is above 89°F and equal to or less than 93°F for less than 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months in a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months day, the diesel is operable with one emergency diesel generator fan capable of operating when the diesel operates. When the outside air temperature is above 93°F, both diesel generator fans must be operable for the diesel to be operable.

The Emergency Outside Air Supply Dampers supply outside air during diesel operation.

These dampers modulate as required between open and closed to maintain a room temperature of 85°F. As the space temperature rises, proportioning controls are provided to modulate the outdoor air dampers toward the open position and the return air dampers toward the closed position. Excess make-up air to the diesel enclosure is relieved through backdraft dampers. These dampers are QA-1 Nuclear Safety Related.

The Return Air Dampers remain in the failed (open) position while the emergency fans are not operating. With operation of the emergency fans the return air dampers are positioned by room temperature controllers to maintain room design temperature. As the room air temperature increases above the room design temperature setpoint, the return air dampers go to a closed position and the outside air dampers go to the open position to supply outside air to cool the room. As the room air temperature decreases below the design room temperature setpoint, the return air dampers and outside air dampers operate in the opposite way. During the summer the room temperature setpoint (85°F) is generally exceeded therefore the room temperature controllers will close the return air dampers and open the outside air dampers. As the return air dampers close excess air is exhausted from the diesel room through relief (backdraft dampers) to the exterior of the building. The return air dampers are QA-1, Nuclear Safety Related.

The pressure operated backdraft dampers are located at the exhaust end of the diesel building room. These dampers open to exhaust air from the Diesel Building to the outside atmosphere. These dampers are QA 1, Nuclear Safety Related and operate during normal and emergency operations.

Summary of 2A EDG Room ventilation performance during the event:

The 2A2 VD Fan was removed from service on November 13, 2023, for planned PM motor replacement. The 2A1 VD Fan was still available for operation; however, it had a degraded temperature controller (2VDTT7500) that caused the respective outside and return air dampers to operate in recirculation mode. With 2A2 VD Fan out of service, and 2A1 VD Fan operating in recirculation mode, there was not a sufficient amount of forced cooling from outside air to maintain 2A EDG Room below 120°F. The 2A1 VD temperature controller was replaced on January 3, 2024 after it was discovered failed to return the 2A1 train to fully functional status. The 2A2 fan motor was subsequently replaced with a new motor on February 6th, 2024 to return the 2A2 train to fully functional status.

Historical trending of 2A EDG Room temperature was completed and determined the same condition that occurred on January 2, 2024 also existed on December 5th, 2023 when the 2A diesel was run for its monthly surveillance test. A review of historical 2A EDG room temperature data prior to December 5th, 2023 determined there is no conclusive evidence that the controller 2VDTT7500 was degraded to the point where the 2A EDG was inoperable. Except for the period between December 5, 2023 and January 2, 2024 (Reference AR2499589-04). The failure of 2VDTT7500 and subsequent 2A

EC 424080 Revision 3 Page 5 of 19 EDG Room temperature increase during EDG operation, resulted in a Maintenance Rule Functional Failure and a License Event Report (LER) (Reference AR 2499589-02 & 25).

To determine the PRA Risk Significance of having 2A2 VD Fan out of service and 2A1 VD Fan operating in recirculation mode, an evaluation was completed to determine five things:

1) The maximum temperature the 2A EDG Room would reach during a 24-hour* assumed accident scenario with 2A2 VD Fan out of service and 2A1 VD Fan operating in recirculation mode from December 5, 2023, to January 2, 2024.

2) The maximum temperature the 2A EDG Room would reach during a 24-hour* assumed accident scenario with 2A2 VD Fan out of service and 2A1 VD Fan operating in recirculation mode from November 13, 2023, to December 5, 2023.

3) The most limiting components (by temperature) in the 2A EDG room that would impact the safety related operation of 2A EDG during the first 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of emergency operation.

4) Determine the outside ambient temperature that will result in a limiting steady state EDG room temperature to 120°F and 131°F with one emergency ventilation fan operating in the once-through ventilation mode.

5) Determine the outside ambient temperature that will result in the 2A EDG room temperature reaching the temperature of the most limiting component (139°F) during a 24-hour emergency run with one fan out of service and the remaining fan operating in recirculation mode.

Although the mission time for 2A EDG is 7 days, for appropriate risk evaluations the PRA team requested 24-hour evaluations vs 7-days.

2A EDG Load Determination:

To determine the maximum temperature the 2A EDG room would reach during a 24-hour period, first the accident loading (kW) of the 2A EDG had to be determined. This is because the largest heat load in the 2A EDG room during engine operation is the 2A EDG itself. The thermal output to the 2A EDG room from the engine is directly related to engine/generator load (kW).

Calculation CNC 1381.05-00-0290 revision 0 2A EDG Accident Loading Determination for MPR Analysis - NCR 2499589 was generated to determine the accident loading value between 11/13/23 and 1/2/24. The calculation determined the LOOP/LOCA loads were larger than just the LOOP loads. Since the LOOP/LOCA loads are bounding, they were used as the input into the MPR model for evaluating 2A EDG Room temperature response. The bounding accident loading value used by MPR as an input into their analysis (CNC-1211.00-00-0148 2A EDG Room Heat Up Analysis - NCR 2499589) summarized in Table 1 below was 4,448kW.

After MPR completed their analysis using the LOOP/LOCA load, it was determined that the PRA risk of a LOOP/LOCA is small and is therefore not considered risk significant. PRA results show the dominate cutsets/scenarios are LOOP. LOCA sequences do not dominate the results. Further, the LOOP/LOCA combination event is such a low probability that it is typically below the truncation (i.e. not included in the results). Therefore, exclusion of some EDG LOCA loads in the room heat-up analysis does not impact the overall PRA results (Reference CNC-1535.00-00-0269 Rev 1, Appendix A). Since the LOCA sequences do not dominate the results, the PRA scenarios for the degraded VD system event involves LOOP evaluation only.

With the shift to evaluating LOOP events only, it was also determined for PRA risk evaluation purposes, the evaluation time frame had to extend beyond 11/13/23 - 1/2/24. CNC 1381.05 0290 revision 1 was generated to re-evaluate the loads for both LOOP/LOCA and LOOP and for

EC 424080 Revision 3 Page 6 of 19 a longer time frame of 8/2/2022-2/6/2024. The revision identified a number of loads that could be removed because they are normally aligned to Unit 1 power source. For the purposes of this analysis, the normal plant alignment of Unit 1 power source to 1EMXG and A Control Room Area Chiller is credited. Therefore, the 1EMXG loads and A Control Room Area Chiller are not added to 2A EDG emergency loading. Revision 1 also conservatively added load group 13 to the 2A EDG accident loading. Load group 13 is not automatically loaded and requires manual operator action. Although it is understood that these loads may not be energized depending on the plant conditions and timing, they were all added for conservatism.

Revision 1 to CNC 1381.05-00-0290 determined the LOOP load to be 4,234 kW. This value is lower than the 4,448kW load used in the MPR analysis. Therefore, the 2A EDG loading values that MPR used for the analysis are bounding and conservative. It should also be noted that the MPR analysis assumed the EDG load is at 4,448kW for 24-hours and does not account for any load reduction that may occur during that 24-hour period.

A.4 Solution For item 1) MPR Associates was contracted to develop an analytical model (GOTHIC) of 2A EDG room to determine the maximum temperature the 2A EDG Room would reach during a 24-hour period with the 2A2 VD Fan out of service and the 2A1 VD Fan operating in recirculation mode. Using the known environmental conditions during the period of 12/5/2023 to 1/2/2024, MPR determined the maximum temperature the 2A EDG would have reached during a 24-hour period during the worst-case outside air temperature conditions. The maximum room temperature the 2A EDG would have reached during the worst case 24-hour period between December 5th,2023 and January 2nd, 2024 is 125.9°F with no operator mitigating action to open the EDG room doors (Reference 1).

For item 2) Using the known environmental conditions during the period of 11/13/2023 to 12/5/2024, MPR determined the maximum temperature the 2A EDG would have reached during a 24-hour period during the worst-case outside air temperature conditions. The maximum room temperature the 2A EDG room would have reached during the worst case 24-hour period between November 13, 2023 to December 5, 2023 is 132.8°F with no operator mitigating action to open the EDG room doors (Reference 1).

For item 3) A multidisciplinary team was used to complete a review of all safety related components to determine which component had the lowest maximum allowable temperature.

There are multiple components that have the lowest maximum allowable temperature of 139°F.

These components are listed in detail in the conclusion section A.9 (Table 5 - Most Limiting Components (by temperature) in 2A EDG Room).

For item 4) Using the already developed GOTHIC model of the 2A EDG room, MPR ran additional cases to determine what outside ambient temperatures will result in a steady state 2A EDG room temperature of 120°F and 131°F with one fan fully functional in once-through ventilation mode and one fan out of service.

For item 5) Using the already developed GOTHIC model of the 2A EDG room, MPR ran additional cases to determine what outside ambient temperatures will result in a 2A EDG room temperature reaching 139°F at the end of a 24-hour emergency run with 2A2 VD Fan out of service and 2A1 VD fan operating in recirculation mode. This analysis also refined the way the

EC 424080 Revision 3 Page 7 of 19 outside air was modeled to more accurately reflect the temperature variations during a typical day.

A.7 Bounding Technical Requirements The following documents were reviewed to understand the basis for 120-degree Fahrenheit Operability limit:

UFSAR Section 9.4.4 Revision 23 VD System DBD. CNS-1579.VD-00-0001 Revision 22 EDG Specification. CNS-1301.00-00-0002 Revision 4 VD HVAC Calculation. CNC 1211.00-00-0013 Revision 29 EQCM. CNLT-1780-03.03 Revision 39 VD TAC Sheet. CNTC-2579-VD.M001-01 Revision 3 VD TAC Sheet. CNTC-2579-VD.M002-01 Revision 1 PRA HVAC System Notebook VD. CNC-1535.00-00-0176.16 Revision 4 From the above list of documents, they all reference back to either the EDG Specification CNS-1301.00-00-0002 and/or the VD HVAC Calc CNC 1211.00-00-0013. The EDG Specification states the maximum room ambient temperature of the Diesel Room will be 125-degrees Fahrenheit, and all equipment located in this room shall be capable of operating under these conditions for a continuous period. The Diesel Generator Building HVAC Calculation provides supporting information for the 120-degree Fahrenheit room temperature limit. The calculation determines the maximum allowable outside air temperature with the diesel in operation, while maintaining the maximum diesel room design temperature of 120 degrees F, with only one emergency fan operating in 100% once-through ventilation mode, and the second emergency fan shut off and its associated dampers in a recirculation alignment (Reference CNC 1211.00-

EC 424080 Revision 3 Page 8 of 19 00-0013 Rev 29 Attachment 20). However, the calculation also provides supporting information for short term excursions up to 125 degrees F for up to 10hr/day for 7 days (Reference CNC-1211.00-00-0013 Rev 29 Attachment 33). Although the Diesel Generator Building HVAC Calculation CNC-1211.00-00-0013 Rev 29 Attachment 33 has provisions that allow operation up to 125°F for up to 10 hour1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months s/day for 7 days, all other design basis documents (UFSAR, EQCM, TAC Sheet, etc) state the maximum room temperature is 120°F. Therefore, the design basis for maximum room temperature is 120 degrees F.

The bounding technical requirements for Operability will remain that a maximum 2A EDG room temperature is 120°F. However, for this evaluation, the FUNCTIONALITY of equipment above the 120°F limit will be reviewed to determine if the 2A EDG will continue to operate at a temperature greater than 120°F.

A.8 Evaluation Room Temperature Determination:

To determine 2A EDG room temperature during various conditions, MPR Associates was contracted to develop an analytical model of 2A EDG room. The analysis was performed using a detailed model of the 2A EDG room that was developed in the GOTHIC software. The model includes the volumes associated with the EDG room, the VD system interconnections and damper alignment, along with key structures in the room. The model simulates the heat loads in the room including the EDG heat load, heat transfer to the walls and structures, air flows created by the fan and other means, etc. The model determines the time-dependent increase in the temperature in the room.

The completed MPR analysis included multiple cases to assist with the Duke Energy operability and PRA evaluations. Some cases used the actual ambient temperature time histories during the period of degradation, simulated the heat-up of the room, and determined the maximum temperatures that would have been reached at the end of 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of emergency operation.

Other cases calculated the maximum constant ambient temperature that would result in the EDG room temperature reaching the limit of 131°F in 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . The limit of 131°F was set by Duke Energy based on an initial evaluation of components in the 2A EDG room that need to remain functional (Revision 0 of this EC).

An additional evaluation was completed to demonstrate that the components that were the drivers for the 131°F limit could tolerate higher temperatures, up to 139°F (Revision 2 of this EC). Hence, the 131°F limit is conservative and higher temperature of 139°F in the EDG room is acceptable. Therefore, Duke Energy requested that MPR analyze additional cases and calculate the new maximum ambient temperature that will result in the room reaching the new higher limit in 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

The various scenarios provided to MPR Associates to model are defined in Table 1. Results of this analysis are shown below in Table 2, Table 3, and Table 4 as well as Reference 1. and Reference 7.

Component Maximum Allowable Temperature Determination:

To determine functionality of all required components in the 2A EDG room at temperatures greater than 120°F, first an applicable list of components had to be created.

To compile the list of components, a mass export of all Engineering Database (EDB) components with a location of *D2A* for 2A EDG room and a documented QA type (no blanks) was completed.

With the EDB list compiled, all the equipment that was not safety related (QA-1) was excluded.

The remaining safety related components were then reviewed to determine the maximum allowable temperature of each component. All individual QA-1 components were evaluated and independently checked by qualified design verifiers to determine the maximum temperature at

EC 424080 Revision 3 Page 12 of 19 which these components can operate, and subsequently this review determined the most limiting components (the components that had the lowest maximum allowable temperature).

This review of all QA-1 components along with all supporting information and evaluations is documented in the e-folder (

Reference:

Review of Components in 2A EDG Room Rev 2.pdf and supporting attachments).

A.9 Conclusion Maximum 2A EDG Room Temperature Evaluation for Past Operability:

Scenarios 1 through 4 were ran to support past operability during the period the 2A2 fan was out of service and/or 2A1 VD Fan was operating in recirculation mode only.

From observation of the outside air temperature between November 13, 2023 and January 3, 2024, MPR performed multiple evaluations to determine which outside air temperature resulted in the highest 2A EDG room temperature. The outside air temperature profiles were provided from Catawba Met Tower data. Sensitivity studies were performed by MPR to determine the worst case temperature profiles during the past operability period that would maximize room temperature. These sensitivity runs were performed as a function of how long the temperature was at the elevated temperature and when the diesel could have started to maximize room temperature. The maximum room temperatures were determined to occur between December 9th - 10th 2023 (Reference 1 Figure 8-2) and November 17th - 18th, 2023 (Reference 1 Figure 8-10). The worst case scenarios were modeled for at 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months time period using a GOTHIC model of the 2A EDG room. The maximum 2A EDG room temperature remained below the most limiting 2A EDG component temperature limit of 139°F for all four case runs. The model results for maximum 2A EDG room temperature for scenario 1 was 125.9°F and the model results for scenario 3 was 132.8°F after the 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months time period. Scenarios 1 and 3 were limiting since no operator action to open the doors were simulated in the model.

Note: The GOTHIC model of the 2A EDG room was benchmarked against the December, January and February EDG tests performed by Duke Energy. The temperatures measured at multiple locations during February 14, 2024 test showed that the OAC EDG room temperature indicators C2A0937 (Diesel 2A Room Temp #1) and C2A0943 (Diesel 2A Room Temp #2) slightly overpredict the average EDG room temperature (by about 2°F). The benchmarking effort based on December 5, 2023 and January 2, 2024 tests showed

EC 424080 Revision 3 Page 13 of 19 that the EDG room temperatures calculated from the GOTHIC model are comparable to the temperature measurements associated with indicators C2A0937 and C2A0943. Therefore, the temperatures reported above for all the cases are slightly conservative.

Maximum Outside Ambient Air Temperature Limit with One Operable VD Fan:

The purpose of scenarios 5 and 6 was for information only purposes to determine the maximum allowable outside ambient air temperature that will result in reaching component temperature limits with one ventilation fan out of service and the alternate ventilation fan fully functional in once-through ventilation mode. The maximum steady state outside ambient air temperature limit with only one operating ventilation unit in service had historically been calculated to be 89°F to maintain a room temperature less than the room design temperature of 120°F (Reference 3 Attachment 20).

Scenario 5 determines the maximum outside ambient temperature for the 2A EDG room to reach 120°F since the design temperature of the room was previously documented as 120°F.

Scenario 6 determines the maximum outside ambient temperature for the 2A EDG room to reach 131°F. The component allowable temperature limit was initially evaluated at 131°F prior to re-evaluating the component allowable temperature limit up to 139°F. This scenario was not re-ran at the revised 139°F component allowable temperature limit.

The scenario 5 model result for maximum outside air temperature is 95°F and the scenario 6 model result for maximum outside air temperature is 105.5 degrees. The results from both scenarios 5 and 6 indicate that the temperature in the 2A EDG room will reach a steady state value beyond the first few hours of continuous engine operation. Therefore, the limiting outside air temperature to prevent reaching 120°F and 131°F in a 24-hour period is the same for a 7-day period.

EC 424080 Revision 3 Page 14 of 19 Maximum Outside Ambient Air Temperature for a Maximum Room Temperature Limit of 139°F:

To understand the potential impact of having 2A1 VD fan in recirculation mode and 2A2 VD fan removed from service at any other time during the year, MPR performed additional analysis to determine what outside air temperature would result in the 2A EDG room reaching 139°F (Reference 1). This information was used as an input into the PRA model to calculate the risk increase with a degraded ventilation system.

Scenarios 7 and 8 determine the maximum outside ambient air temperature with a constant air temperature for a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months period. This is conservative since there is a true variation in temperature throughout the day. Scenario 7 assumes no action to open the diesel room doors and Scenario 8 assumes the 2A EDG room doors are opened as a mitigating action 60 minutes after the 2A EDG room reaches the 110°F room temperature alarm.

Scenarios 9 and 10 determine the maximum outside air temperature in a two step process assuming the outside ambient air temperature is at the maximum temperature for 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months and at a low temperature for 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months . Assuming the outside air temperature is at a maximum value for 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months is conservative since there is a variation in temperature over the 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months period. It is also conservative to assume a variation of only 10°F from the high to low temperature since historical data indicates that the variation in temperature exceeds 10°F. Scenario 9 assumes no action to open the EDG room doors and Scenario 10 assumes the EDG room doors are opened as a mitigating action 60 minutes after the EDG room reaches the 110°F room temperature alarm.

Component Temperature vs Room Temperature:

Scenarios 1 and 2 were ran to support data from December 5th, 2023 to January 3rd, 2024.

The maximum 2A EDG room temperature remained below the most limiting 2A EDG component temperature limit of 139°F. The 2A2 fan was out of service and the 2A1 fan was failed such that it would only operate in recirculation mode. The model results for maximum 2A EDG room temperature for scenario 1 with no operator action to open doors was 125.9°F and the model results for scenario 2 was 123.6°F which credits operator action to open the 2A EDG room doors within 30 minutes after receiving a high temperature alarm at 110°F room temperature.

Scenarios 3 and 4 were ran to support data from November 13th, 2023 to December 5th, 2023.

The maximum 2A EDG room temperature remained below the most limiting 2A EDG component temperature limit of 139°F. The 2A2 fan was out of service and the 2A1 fan was assumed to be operating in recirculation mode. The model results for maximum 2A EDG room temperature for scenario 3 with no operator action to open doors was 132.8°F and the model results for scenario 4 was 130.5°F which credits operator action to open the 2A EDG room doors within 30 minutes after receiving a high temperature alarm at 110°F room temperature.

Scenarios 5 and 6 were ran for information only to determine what the maximum outside ambient air temperature could be that will result in reaching room or component allowable temperature limits with one fan fully functional in once through ventilation mode and one fan out of service. The results from both scenarios 5 and 6 indicate that the temperature in the 2A EDG room will reach a steady state value beyond the first few hours of continuous engine operation. Therefore, the limiting outside air temperature to reach 120°F and 131°F in a 24-hour period is the same for a 7-day period. The model results determined with one fan operating in once-though ventilation mode and one fan out of service, an outside ambient temperature of 95°F would result in a steady state temperature in 2A EDG room of 120°F. An outside ambient temperature of 105.5°F would result in a steady state temperature in 2A EDG room of 131°F.

Scenarios 7 and 8 were ran to determine the maximum outside ambient air temperature that would result in a maximum 2A EDG room temperature of 139 degrees. These scenarios assumed a constant outside ambient air temperature for a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months period. This is conservative since there is a true variation in temperature throughout the day. The 2A1 Fan was modeled operating in recirculation mode and 2A2 fan was modeled out of service. Scenario 7 assumes no action to open the diesel room doors and scenario 8 assumes the 2A EDG room doors are opened as a mitigating action 60 minutes after the 2A EDG room reaches the 110 degree F room temperature alarm. The maximum outside ambient air temperature results for scenario 7 was 78.9°F and the maximum outside air temperature results for scenario 8 was 82.2°F.

Scenarios 9 and 10 were also ran to determine the maximum outside ambient air temperature that would result in a maximum room temperature of 139°F. Scenarios 9 and 10 however;

EC 424080 Revision 3 Page 18 of 19 determine the maximum outside air temperature in a two step process assuming the outside ambient air temperature is at the maximum temperature for 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months and at a low temperature for 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months . Assuming the outside air temperature is at a maximum value for 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months is conservative since there is a variation in temperature over the 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months period. It is also conservative to assume a variation of only 10 degrees from the high to low temperature since historical data also indicates that the variation in temperature exceeds 10 degrees. The 2A1 Fan was modeled operating in recirculation mode and 2A2 fan was modeled out of service. Scenario 9 assumes no action to open the 2A EDG room doors and scenario 10 assumes the 2A EDG room doors are opened as a mitigating action 60 minutes after the 2A EDG room reaches the 110 degree F room temperature alarm. The maximum outside ambient air temperature results for scenario 9 was 70.8°F for the first 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months and 80.8°F for the second 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months . The maximum outside ambient air temperature results for scenario 10 was 74°F for the first 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months and 84°F for the second 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .

2A EDG Fan Motor 2A1 Starter and Interposing Relay The 2A Emergency Diesel Generator Vent Fan Motor 2A1 is assumed to be running during the 24-hour postulated situation. This fan motor is energized by a size 3 Joslyn Clark starter (P/N T13U033-76) and an Eaton interposing relay (P/N 9575H3A000) which are identified as "M" and "CR" on CNEE-0220-05.01-

02.

The size 3 Joslyn Clark starter has an allowable abnormal peak temperature of 122°F (50°C) for 100 days total during its qualified life of 40 years, but not to exceed more than five consecutive days per of EC 401157. This starter was installed on 8/8/2019 per WO 20271993.

The interposing relay is an open electromagnetic style relay with DPDT silver cadmium oxide gold flashed contacts. The relay has a documented operating range of -22°F (-30°C) to 131 °F (55°C) per Volume 7 of Eaton's catalogue for Logic Control, Operator Interface and Connectivity Solutions dated September 2020. This relay was installed on 6/13/2017 per WO 20122714.

The worst-case temperature during the postulated situation is 139°F (59.4°C). Both of the subject components have documented temperature ratings below this worst-case temperature. It should be noted that the temperature limitations are provided to ensure that the components are capable of operating for the full duration of their rated service lives. The relay is approximately 7 years old, while the starter is 5 years old. The relay does not have a documented service life, but the expected life of the starter is 40 years. As each of these components are relatively new, it is reasonable to assume that the provided temperature limitations are conservative, and the components would be expected to perform their required design function during the 24-hour postulated scenario. To validate this assumption, a test was performed at the McGuire Metallurgy Lab.

To emulate the postulated situation, a new interposing relay (9575H3A000) and starter (T13U033-76) were wired in a similar configuration to the 2A Emergency Diesel Generator Vent Fan Motor 2A1 (CNEE-0220-05.01-02). A 120 VAC source was configured to provide power to both the starter coil and relay coil in parallel. The neutral side of the relay coil was wired in series with the starter overload. The neutral side of the starter coil was wired in series with a normally open contact on the relay. See Figure 1 below.

Figure 1 Figure 2 120 VAC CR.

2A EDG Fan Motor 2A1 Starter and Interposing Relay As discussed above, the worst-case ambient temperature in the 2A Emergency Diesel room is expected to be 139°F (59.4°C). Temperature inside the associated MCC cubicle (2EMXE/F04A) will be higher as a result of temperature rise. A typical temperature rise assumed for MCCs is 18°F (10°C) per IEEE 649-2006, which would result in an ambient temperature inside the cubicle of 157°F (69.4°C). However, for conservatism, a temperature of 170°F (76.7°C) was selected for the environmental chamber test temperature, which allows for a diesel room ambient temperature of up to 152°F (66.7°C). The duration of the test was 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months to match the required run time of the Emergency Diesel Generator. To monitor the functionality of the relay and starter, contact resistance was monitored across each of the three starter contacts to ensure that it would have been capable of keeping the 2A1 Vent Fan Motor energized throughout the test.

The starter and relay were then placed inside an environmental test chamber and energized. The test was started after the ambient temperature inside the chamber reached 170°F and concluded after 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . Throughout the test, the contact resistance of the starter was monitored. The contactor contacts remained closed during the entire test, which would keep the fan operating throughout the 24-hour period.

It is therefore reasonable to assume that based on the robust electromechanical design of the starter and relay, the relatively young age of the installed components, and the results of the experiment performed at the McGuire Metallurgy Lab, that the components can be expected to function throughout the postulated 24-hour scenario.

2A Diesel Generator Battery Charger (2DGCA) Evaluation to Support EC 424080 Rev. 2 6/26/2024 Page 1 of 6

1. Purpose/Problem Statement The scenario described in EC 424080 is that during a postulated event, due to 2A2 VD fan out of service and 2A1 VD Fan operating in recirculation mode, it was determined that temperatures in the 2A EDG room could exceed the design maximum temperature of the 2DGCA battery charger of 55°C (131°F) as stated in CNM 1356.08-0003.001, Section 1. During the time periods stated in EC 424080, it is postulated that, worse-case, the design maximum temperature would be reached in approximately 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months following a diesel start and temperatures would increase to a temperature of 60°C (140°F) at the end of the 24-hour period.

The purpose of this evaluation is to assess with reasonable assurance, the ability of the 2DGBA battery charger to continue to perform for the entire 24-hour period that includes a prescribed temperature excursion beyond its maximum design temperature in the 2A Diesel Room after 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months .

2. Proposed Solution Utilizing Solidstate Controls letter provided to Oconee Nuclear Station on February 11, 1997 for a 600 Amp Battery Charger (model BCS12600), evaluate the applicability of the letter to the 2DGCA 75A battery charger (model BCS12075) by performing a general comparison of components. If found applicable, the document would provide reasonable assurance that the CNS Diesel Battery Charger would continue to perform while operating during the ambient temperature excursion above its maximum designed temperature of 55°C (131°F).

The letter was a response to an inquiry from ONS requesting SCI to evaluate the ability of their battery charger to operate for a period up to 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months at a temperature of 60°C (140°F). The letters conclusion states that SCI is confident that the equipment will perform during this excursion. See Attachment 1 for complete response.

2A Diesel Room will exceed 2DGCA design maximum temperature of 55°C (131°F) 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months following a diesel start in response to a postulated event.

2A Diesel Room will not exceed 60°C (140°F) during the 24-hour period.

2DGBA has performed its 2-hour discharge and has been fully charged prior to reaching 2DGCA design maximum temperature. Per CNC-1381.05-00-0050,

2A Diesel Generator Battery Charger (2DGCA) Evaluation to Support EC 424080 Rev. 2 6/26/2024 Page 2 of 6 the diesel battery charger can complete within 8-hours. (2-hour discharge + 8-hour recharge)

2DGCA subcomponents required to be replaced on a 10-year basis per CNM-1356.08-0003.001 Revision 8 are not at the end of service life. PM history for the 2DGCA battery charger was reviewed and the major component replacement PM was last performed on 9/15/2016 and is not due to be performed again until 9/13/2025.

5. Evaluation The referenced ONS battery charger models evaluated by SCI are sized much larger than the CNS Diesel Battery Charger, but the components of the chargers are similar and in many instances are the same. For example, all of the identified components required to be replaced on a 10-year basis (denoted by an

are the same part with the exception of the power fuses (F301 - F303).

2A Diesel Generator Battery Charger (2DGCA) Evaluation to Support EC 424080 Rev. 2 6/26/2024 Page 4 of 6 Basis for Acceptability of differences:

1. The Manufacturer and Part Number are identification attributes and do not affect the design/function of the item, therefore, these differences do not impact the evaluation.

2. The Input and Output current value differences due to the ONS battery charger being designed to carry significantly more loading than the CNS diesel battery chargers. Therefore, these differences do not impact the evaluation.

3. The ONS battery charger B301 input breakers are rated for a higher continuous amperage than the CNS battery charger breakers, but both are considered to be similar in construction/materials and would be applicable to the ONS letter from SCI.

4. The ONS battery charger B302 output breaker is rated for a higher continuous amperage than the CNS battery charger output breakers, but both are considered to be similar in construction/materials and would be applicable to the ONS letter from SCI.

5. The ONS Parts list provides the part number for the R301, R302 Float/Equalize Potentiometer as 80-221400-90, but the replacement schedule and Service Bulletin listed in OM 320.--0179.001 Rev. 12 suggests that the actual part number is the same as CNS as 80-221401-90. There is reasonable assurance that the design/construction of the component from ONS is similar to that of the CNS battery chargers.

6. There is reasonable assurance that design/construction of the component is similar across multiple SCI battery charger designs. Majority of the differences is associated with the load each charger is designed to supply. Therefore, using engineering judgement, the ONS letter from SCI is still considered applicable.

7. The Shunt, G301, is shown on 2DGCAs schematic (CNM-1356.08-0002.001) and provides the ability to monitor the output charging current via ammeter A301. The shunt is rated for 150A, which is 2X higher than charger nameplate rating of 75A and provides substantial margin from overheating and failure of the shunt. The ONS charger similarly indicates a shunt included in their design as shown on their charger schematic in OM 320.--0179.001 Rev. 12. Therefore, it is not expected that the combination of rising ambient temperature and output current would cause excessive thermal stress that would result in failure of the shunt.

8. The D305 is shown on battery charger schematic, CNM-1356.08-0002.002, and acts as a blocking diode with the intent to prevent a failed charger from acting as a load on the batteries. The diode is rated for 165A, which is greater than 2X higher than charger nameplate rating of 75A and provides substantial margin from overheating and failure of the blocking diode. The construction materials of diode would be expected to be similar to other diodes utilized throughout the construction of the CNS diesel voltage regulator (evaluated on the component spreadsheet of EC 424080 and are rated above 140°F.

9. The S301 switch on the battery chargers is the switch that allows the customer to change the charger mode to FLOAT or EQUALIZE. The difference between the ONS and CNS battery charger toggle switches is that the ONS switch is momentary while the CNS toggle switch is either in the FLOAT or EQUALIZE position. There is reasonable assurance that the design/construction of the component from ONS is similar to that of the CNS battery chargers.

10. The 150A Fuses are the power fuses for the CNS Battery Charger and would be comparable to the design of the 800A Fuses that are utilized in the ONS Battery Charger. Therefore, using engineering judgement, the ONS letter from SCI is still considered applicable.

11. The L302 utilized on the CNS Battery Charger design is another smoothing inductor that would be considered similar to the components discussed in Note 12.

12. The purpose of the Choke L301 is to smooth the rectifier output as described in CNM-1356.08-0003.001, Section 4.1 prior to the output feeding through the output breakers to the battery and other DC connected loads. It is considered a passive element. The part is an inductor which is similarly used on the ONS battery charger, L301. ONS battery chargers L301 part is p/n 80-314047-90 and is also an inductor. Therefore, there is reasonable assurance that the design/construction of the component from ONS is similar to that of the CNS battery chargers

13. These resistors are assumed to be of similar construction and design as the other resistors utilized in the construction of the ONS Battery Charger listed in the comparison chart. Therefore, using engineering judgement, the ONS letter from SCI is still considered applicable.

14. The Ammeters used on the battery charger is indication only of the battery charger output current and would not impact the operation of the charger if it failed. The only difference between the two items is the range of current that can be measured

2A Diesel Generator Battery Charger (2DGCA) Evaluation to Support EC 424080 Rev. 2 6/26/2024 Page 6 of 6 due to the difference in size of both battery chargers. Therefore, there is no concern about the difference in components.

The SCI response to ONS dated 2/11/1997 (Attachment 1) is broadly based upon SCIs testing performed on similar inverters and battery chargers to the ONS battery chargers and their own experience history on the equipment. Thus, it is deemed applicable that the document can be expanded to the CNS 2A Diesel Generator Battery Charger (2DGCA) given its own similarities to the ONS Battery Chargers referenced in the Fax sent from ONS to SCI on 11/201996 as shown above.

The scenario proposed by ONS is such that the battery chargers would be expected to operate in an environment at 60°C (140°F) continuously for a period of 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months . This CNS evaluation is assuming that temperatures will not exceed 60°C (140°F) during a 24-hour period and that the charger will only operate above its maximum design temperature of 55°C (131°F) for 14 hours1.62037e-4 days 0.00389 hours 2.314815e-5 weeks 5.327e-6 months .

The 2A Diesel Battery Charger is sized for a rated output of 75 amps with a current limit of 86 amps per CNM-1356.08-0003.001. The diesel battery charger sizing calculation, CNC-1381.05-00-0050 Revision 12, determined that the charger is required to be sized for a minimum output current of 58.95 amps which includes continuous loads (50.24 A) and non-continuous loads (8.71 A). The continuous load includes the current required to recharge the diesel battery over an 8-hour period (approximately 6.74 A) which is expected to be complete prior to operating beyond the design maximum temperature. Leaving this value in the minimum requirement provides margin to any increase in charging current required of the diesel battery associated with electrolyte temperatures. At 58.95, the battery charger would be loaded just under 79% of its rated output current of 75A. This would result in less operational induced thermal stresses imparted on internal components of the 2DGCA.

6. Conclusion Based on the similarities between the ONS battery chargers and the CNS diesel battery charger (2DGCA) designs and components used, the letter form SCI to ONS, and the approximate charger output current at less than 79% of the rated 75A; there is reasonable assurance that 2DGCA will continue to operate and provide 125VDC to the required loads during the entire 24-hour period of the postulated scenario provided in EC 424080 Rev. 2.

Dear Rick,

Dennis E. Dellinger 875 Dearborn Dr.

800-635-7300 Project Engineer

Columbus, Oh 43085 Fax 614-885-3990 First let me apologize for the delay in g~tting the information that you requested last year.

I have evaluated the time and temperature profile that you have included for the postulated room temperature on accident conditions. A comparison was made to determine the temperature rise on components within the battery chargers and inverters based on the final temperature after 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months .

While the temperature rise on some component's is more that what we can recommend, SCI has performed tests on similar inverters and battery chargers and the equipment has survived the elevated tempe'rature levels equal to that which is postulated. In some cases the temperature level's are higher.

Based on the evaluation of the components, actual testing and experience history, SCI is confident that the equipment will perform during this excursion.

If you have any other needs or comments, please contact me.

2DGCPA Breaker 19 Load Evaluation Breaker 19 (15 A) in D/G-2A Generator Control Panel (2DGCPA) provides protection for certain voltage regulator, governor, field flash, and miscellaneous relays for D/G-2A (References 9

&10). The breaker is a GE THED breaker (References 6 & 11).

Assumptions:

1) A 10°F temperature rise is assumed for 2DGCPA.

2) Inrush current is not a concern since all changes in state of the various control components occurs early in the event when Diesel Room temperature is still at or below the maximum Diesel Room Design Temperature of 120°F.

3) Though DC voltage is typically 132 VDC, the steady-state current is calculated using 125 VDC, which provides a conservative result.

The GE THED breakers were previously evaluated by Brunswick Nuclear Station per Qualification Data Package QDP 67A (Reference 8). One concern with breakers is the possibility of the thermal trip unit actuating on elevated temperature. Section 3.5.2.2 of QDP 67A (page 48) states that these breakers are ambient compensated up to 50°C (122°F). Table 3.5.2.1 (page 49) provides percentage derating of the breakers for ambient temperature correction. Based on Table 3.5.2.1 of QDP 67A, a THED breaker should be derated to 72% at 80°C (176°F).

The worst-case ambient temperature in the Diesel Room during the postulated situation is 139°F (59.4°C) plus a 10 F° rise assumed in 2DGCPA resulting in 149°F at the breaker. However, the breaker is evaluated below for a derating at 176°F (80°C), which would allow for a Diesel Room ambient temperature as high as 166°F (74.4°C) for conservatism.

Breaker 19 Derating @ 176°F = 15 A (0.72) = 10.8 A By evaluating the components fed from Breaker 19 per References 9 & 10, initial Steady-State Current is documented in the table below:

Based on the above, current through Breaker 19 in 2DGCPA remains below 1 A, which is < 10%

of the 15 A breaker rating. Since the breaker load of 1A is well below the derated breaker rating of 10.8 A, Breaker 19 in 2DGCPA is not expected to trip or mis-operate during the evaluation period; therefore, D/G-2A operation is not affected.

Page 1 of 6 Valve 2RN846A and Valve 2RN847A Evaluaon On 1/2/24, the 2A1 VD fan/controller was iden"ed to be failed and not controlling the 2A EDG Room temperature during 2A EDG Operability test (PT/2/A/4350/002A). The Diesel Generator Emergency Venlaon poron of the VD System is required to maintain the Diesel Building temperature between 60°F and 120°F during any Design Basis Event (such as a LOCA) coincident with a Loss of Osite Power (LOOP), Reference CNS-1579.VD-00-0001. During the 2A EDG Operability test on 1/2/24, the 2A EDG room temperature increased from 81°F to 106°F with no sign of stabilizing. It is expected that the 2A EDG room temperature would have increased > 120°F due to the failed 2A1 VD fan/controller if the 2A EDG had not been secured.

This evaluaon will review the impact on valve 2RN846A 2A Diesel Generator HX Return to SNSWP Motor operator (MOV) and valve 2RN847A 2A Diesel Generator HX Return to Lake Motor operator (MOV) due to the 2A EDG room temperature increasing > 120°F.

The MOV for valve 2RN846A is powered from the 600V Motor Control Center 2EMXE COMPT# F01B

2) TM Starter (Design Max Allowable Temperature 122°F)

8) Tefzel wire (Design Max Allowable Temperature 228°F)

The MOV for valve 2RN847A is powered from the 600V Motor Control Center 2EMXE COMPT# F01C

1) Breaker - HFB3020 (Design Max Allowable Temperature 257°F)

2) TM Starter (Design Max Allowable Temperature 122°F)

7) Type MTW wire (Design Max Allowable Temperature 194°F)

8) Tefzel wire (Design Max Allowable Temperature 228°F)

As referenced above, the TM Starter has a maximum design temperature limit of 122°F and Primary P-FU Fuses have a maximum design temperature limit of 120°F for valves 2RN846A and 2RN847A. It can therefore be assumed that valves 2RN846A and 2RN847A would not be able to operate during a design basis event with the failed 2A1 VD fan/controller.

During normal RN system operaon, valve 2RN846A is closed and 2RN847A is open discharging to Lake Wylie. If an Emergency Low Pit Level (either pit) is received, the RN System sucon and discharge will swap from Lake Wylie to the Pond (SNSWP). This evaluaon assumes that the pit swap occurs aer the 2A EDG room has exceeded its design temperature limit of 120°F and the 2A EDG cooling water outlet valves, 2RN846A and 2RN847A, do not correctly posion.

The RN System Fathom Flow Model (Reference CNC-1223.24-00-0027) was used to determine the impact on the RN System if valves 1RN846A and 1RN847A do not swap during an Emergency Low Pit

Page 2 of 6 Level (Loss of Lake Wylie), Unit 2 Loss of Coolant Accident (LOCA), and Dual Unit Loss of Osite Power (LOOP) event.

Figure 1: Fathom Model of the RN System The Fathom model was run in the following scenario:

Dual unit LOOP event, all four Emergency Diesel Generators and RN pumps will start. Due to variaons in frequency and voltage, the Fathom model has adjusted all four of the RN pump speeds to 101.945 percent, reference CNC-1223.24-00-0027 Atachment 8. All of the KD HX outlet throtle valves 1(2)RN236 and 1(2)RN296 locked in their throtled posions as set by the RN system "ow balance. All of the KC HX RN outlet throtle valves 1(2)RN291 and 1(2)RN351 are failed in the full open posion. The model was run with the 2B NS HX in operaon with valve 2RN836 failed to the full open posion since Unit 2 is the LOCA unit. Flows through the 1A, 1B, and 2A NS HXs are isolated. The B YC Chiller is in service with its outlet throtle valves 1RN304B and 1RN305 failed to the full open posion. Flow is isolated to the A YC Chiller. Flow is isolated to the Unit 1 and Unit 2 Non-Essenal headers by the automac closure of the supply header crossover valves 1(2)RN47A and 1(2)RN48B. RN is supplying the 2B CA Pump with 510 gpm.

Page 3 of 6 The Fathom model scenario has the RN pump sucon aligned to the SNSWP. The SNSWP level used in the Fathom model was determined by a review of the OAC/PI point C1A1013 (SNSWP Level). The lowest pond level iden"ed during the me period between 10/1/22 through 1/2/24 was 573.23 feet which occurred on 11/15/23. This pond level was used in the Fathom model scenario.

Figure 2: SNSWP Pond Level 11/13/23 - 1/2/24 The Fathom model scenario had all of the RN system discharge "ows aligned to the SNSWP except for the 2A KD HX since valves 2RN846A and 2RN847A could not be relied upon to swap due to the 2A EDG room temperature > 120°F which exceeds the design temperature limit of the valves MOV TM Starter and Primary P-FU Fuses. This scenario results in the SNSWP pond inventory being discharged to Lake Wylie through the 2A KD HX through valve 2RN847A.

The Fathom Model output for the scenario described above is as follows:

The 2A EDG has a 7 day mission me; therefore, the calculated loss of SNSWP inventory to Lake Wylie through the 2A Diesel Generator Jacket Water Cooler would be 11,158,560 gallons of water.

The calculated volume in acre-is calculated as follows:

Page 5 of 6 The total loss of SNSWP during the 7 day period is a total of the losses to Lake Wylie and the total of the design consideraons above.

TOTAL Volume = 34.247 + 17.132 = 51.379 acre-feet From CNC-1150.01-00-0001 (SNSWP Thermal Analysis During One Unit LOCA and One Unit Shutdown),

The SNSWP volume at the 573.87 elevaon is calculated to be 576.7 acre-feet.

The resulng SNSWP Volume based on the inial SNSWP Pond Level of 573.87 elevaon minus the total volume from the lost through 2RN-847A to Lake Wylie and other analyzed losses is calculated as follows:

The "nal volume results in a SNSWP level of 572.166. This level is greater than the required level of 571 feet from Tech Spec 3.7.9.

Conclusion:==

Through the me period of October 1, 2022 and January 2, 2024, the minimum SNSWP level was 573.23 feet. If a design basis event had occurred with the failure of 2RN-846A to open and 2RN-847A to close, the discharge of the 2A Diesel Generator Jacket Water Cooler RN system would have been aligned to Lake Wylie. This would result in an unanalyzed loss of inventory from the SNSWP during the 7 day diesel generator mission me. Combined with the analyzed SNSWP losses per CNC-1150.01-00-0001, the total loss of SNSWP inventory during the 7 day mission me of the 2A EDG would be 51.379 acre-. The SNSWP pond level would have decreased from 573.23 to 572.166 which is greater than the required minimum SNSWP pond level of 571 per Tech Spec 3.7.9 and the level aer the "rst 7 days of the event 570.26 per SNSWP pond analysis calculaon CNC-1150.01-00-0001 Revision 19.

This evaluaon assumes that valves 2RN-846A and 2RN-847A would not have been able to electrically operate due to exceeding the maximum design temperature limit of 122°F for the TM Starters and 120°F for the Primary P-FU Fuses. Although the valves could not have been relied upon to electrically operate, it should be recognized that the valves could have been manually operated. Both valves have Limitorque SMB-000-2 actuators. Valve 2RN-846A could have been manually opened and valve 2RN-847A could have been manually closed by depressing the actuators declutch lever and rotang the

CNS EDG Room 2A Heat-up Analysis - EDG Surge Suppressor Capacitor Evaluation

Dear Mr. Stewart:

The purpose of this letter is to forward the requested revision to the evaluation of the Catawba Nuclear Station (CNS) Emergency Diesel Generator (EDG) surge suppressor capacitor temperature rating and its suitability for its application, given the maximum EDG room temperature resulting from the subject analysis. The previous revision provided an evaluation that bounds the potential maximum EDG room temperature of 140°F. This revision incorporates minor changes to reflect final calculation references and a revised Attachment 2 (removed unrelated text from email attachment).

Our evaluation concludes that the CNS EDG surge suppressor capacitor supports the EDG safety related operation at the maximum calculated EDG room temperature for an EDG start with one of the emergency ventilation fans out of service and the other fan remaining in the recirculation mode of operation.

Please feel free to contact me, at (703) 519-0255, or Frank Del Campo, at (860) 440-9843, with any questions you may have on this letter and the enclosed evaluation.

MPR CELEBRATING 60 YEARS

Enclosure to 2079-0070-LTR-002, Rev. 3 MPR Letter Dated July 30, 2024 Evaluation of CNS EDG Surge Suppressor Capacitor 1.0 Purpose The purpose of this evaluation is to demonstrate that the Catawba Nuclear Station (CNS)

Emergency Diesel Generator (EDG) surge suppressor capacitor supports the EDG safety related operation for the maximum calculated EDG room temperature.

2.0 Background

CNS utilizes two EDGs per Unit that are in dedicated rooms that each have their own safety related HVAC systems. After a Loss of Power, the EDGs provide electrical power to the components in the plant that are critical for safe shutdown. The EDG mission is to provide uninterrupted power to these components in accordance with the CNS licensing basis.

To facilitate the EDG safety functions and the functions of other supporting equipment in the EDG rooms, the temperature in the rooms needs to be maintained at or below certain limits, as discussed in Reference 1. The diesel building ventilation system is designed to maintain the building temperature between 60°F minimum and 110°F maximum when the EDG is not operating, and between 60°F minimum and 120°F maximum when the EDG is operating. The current plant design analysis and calculations are based on the EDG room temperature that is limited to be below 120°F during EDG operation. Duke Energy has determined that the supporting equipment in the room can operate adequately and perform its function at temperatures greater than 120°F as documented in Engineering Change Number 424080 (Reference 2).

A recent equipment issue discovered during monthly surveillance tests of EDG 2A has prompted the need to perform an analysis that simulates the EDG room heat-up that is expected after an EDG start with one of the emergency ventilation fans out of service and the other fan remaining in the recirculation mode of operation. MPR previously completed this analysis and showed that the maximum temperature in the EDG room is a function of multiple parameters driven largely by the outside air ambient temperature during the course of the EDG run. MPR analysis indicates a maximum peak room temperature of 132.8°F during the evaluation period (November 17, 2023 to December 10, 2023). However, other date ranges may impact EDG PRA analysis so an evaluation to allow all components to operate at 140°F is being pursued. This peak temperature challenges the operability of the EDG. Duke Energy is using the results of MPRs revised analysis to evaluate the past operability of the EDG and for PRA evaluation. Duke Energy previously requested MPR to assist with their past operability determinations, specifically with

2079-0070-LTR-002, Rev. 3 the evaluation of the EDG surge suppressor capacitors ability to support the EDG safety related function while being subjected to the peak EDG room temperature predicted by MPRs analysis.

The MPR evaluation of the capacitor for the peak temperature of 132.8°F is documented in Revision 0 of this letter report. This revision evaluates the capacitor for the higher peak temperature of 140°F.

3.0 Evaluation 3.1.

Equipment Description Each CNS EDG includes voltage surge protection from a surge suppressor capacitor connected to its output terminals as shown on Reference 3. The EDG surge suppressor capacitor is located at the bottom section of the EDG A.C. Outlet Box Assembly, as shown in Reference 3 and Figure 3-1. A photograph of the associated nameplate is provided via Figure 3-2. The nameplate indicates that the EDG surge suppressor capacitor was manufactured by Westinghouse and is a three pole Type DV Surge Protection Capacitor per part number 1NO2180A01A, containing Wemcol Non-PCB combustible fluid and rated 7200/4160V, 60 Hz, and 0.5 uF.

2079-0070-LTR-002, Rev. 3 Figure 3-2. CNS EDG Surge Suppressor Capacitor Nameplate The EDG surge suppressor capacitors installed at CNS are no longer available from Westinghouse. This surge suppressor capacitor type was later supplied by ABB, and now is supplied by Hitachi Energy. Per Hitachi Energy, the Westinghouse 1NO2180A01 capacitor was replaced by ABB the 2GUS031803A1 capacitor, now supplied by Hitachi Energy. Hitachi Energy cannot confirm that the ABB version is fully identical to the older Westinghouse version, however they did state that the electrical output is identical (See Attachment 1).

3.2.

General Function The stator winding insulation systems for electrical machines, such as EDGs, have a relatively low impulse strength that are subjected to normal stresses from steady state operating voltages as well as the more damaging stresses caused by steep-fronted surges (high rate of rise) of high voltage (A steep fronted surge has a rise time of less than one microsecond). The voltage surges in electrical systems can be caused by events such as lightning strikes, circuit breaker operation, and the switching of power factor correcting capacitors to name a few. For the EDGs, the greatest and most common cause for voltage surges is from the switching action of circuit breakers within the electrical system. The basic arc-quenching techniques of the vacuum circuit breakers give rise to current chopping and multiple re-ignition events that generate the voltage surge, especially when the connected load is inductive in nature. The voltage surge travels away from the initiating source (the breaker) and when an impedance change occurs, such as at the

2079-0070-LTR-002, Rev. 3 terminals of the EDG, the surge wave gets reflected back and results in a travel/reflection cycle that is repeated multiple times that can cause the voltage of the system to rise to several times the rated voltage. A surge suppressor capacitor is used to limit the effects of the voltage surges thus providing protection for the EDG insulation systems (References 4 through 7).

Per IEEE C62.21 (Reference 5), conventional practice prior to 1981 was to reduce the rate of rise of the voltage surge by lengthening the surge voltage wave front so that the time to reach peak was ten microseconds or more. This was considered the safe time to reach surge withstand voltage for the machine. Since 1981, a surge front as short as five microseconds has been accepted as safe for most machines. In the case of modern large machines, such as EDGs, surge fronts of three or four microseconds might be safe. However, the extent to which successive impulses may age machine insulation is not known with certainty. Conservatism is advisable in dealing with the protection of vital machines such as EDGs and the conservative five microsecond front for all machines is desirable for this reason. It permits a standardized method of surge protection. There is historical experience behind this approach whereby capacitor values have been established that achieve the five microsecond surge front for different voltage applications. Per References 5, 7, and 8, an accepted practice is to use a capacitance of 0.5 microFarad (uF) for machines rated from 2400 to 6900V, 0.25 uF between 11.5 to 13.8kV and 0.125uF for ratings 14.4kV and above.

3.3.

Design and Safety Functions The design function of the surge suppressor capacitor is to limit the over-voltages in the electrical system that is associated with the EDG to a level lower than the withstand voltage of the generator insulation systems.

This is not a safety function but rather a protective function provided by the surge suppressor capacitor. Due to its application in a safety related electrical system, the surge suppressor capacitor, as an associated component, is required to be qualified as a safety related component in order to ensure that the EDG and electrical system safety function is not adversely affected.

Therefore, the EDG surge suppressor capacitor has no active safety related function. However, the EDG surge suppressor capacitor does have a passive safety related function to not fail in a way that affects the safety function of the EDG.

3.4.

Temperature Related Failure Modes and Affects The EDG surge suppressor capacitor can fail in an open circuit state or a closed (short) circuit state. However, the failure condition of a failed capacitor is generally a short-circuit condition.

If the EDG surge suppressor fails in an open circuit state, the EDG would be subjected to any voltage surge condition. Existing EDG protective relaying settings are likely not adjusted to provide any protection to this condition, especially when the EDG is performing its safety related function.

If the EDG surge suppressor capacitor fails in a short-circuit condition, the affected phase will have a connection to ground. Either the short circuit will convert to an open circuit (due to

2079-0070-LTR-002, Rev. 3 damage to the capacitor from the fault current) or the existing EDG protective relaying will detect a short circuit condition and trip the EDG output breaker, adversely affecting the safety related function of the EDG.

Subjecting the EDG surge suppressor capacitors to temperatures above their ratings may degrade their dielectric properties. Degraded dielectric properties could affect the performance of the capacitors or reduce their life. It is therefore concluded that frequent operation at temperatures above the ratings of the capacitors will shorten the life expectancy of the capacitors and may result in the capacitors failing in a state that adversely affects the safety related function of the EDG.

3.5.

CNS EDG Surge Suppressor Capacitor Temperature Rating The EDG surge suppressor capacitor temperature rating will be established using industry operating experience (OE) and technical inputs obtained from datasheets for similar equipment, as well as from discussions with Hitachi Energy. The EDGs at V.C. Summer (VCS) include voltage surge protection for Westinghouse surge suppressor capacitors very similar to those installed at CNS. Vendor documentation associated with the specific Westinghouse part numbers used for the VCS and CNS EDG surge suppressor capacitors is limited. A very exhaustive search for temperature ratings was performed, with no published ratings found.

VCS EDGs include surge suppressor capacitors that are very similar to that of CNS (same Westinghouse type, but single pole with different voltage and capacitance ratings). A photograph of the associated nameplate is provided via Figure 3-3. The nameplate indicates that the VCS EDG surge suppressor capacitor was manufactured by Westinghouse and is a single pole Type DV Surge Protection Capacitor per part number 1NO2180A03A, containing Wemcol Non-PCB combustible fluid and rated 13800V, 60 Hz, and 0.25 uF.

2079-0070-LTR-002, Rev. 3 Figure 3-3. VCS EDG Surge Suppressor Capacitor Nameplate The VCS EDG surge suppressor capacitors are installed in the Exciter Magnetics Enclosure, as shown in Figure 3-4. Per Reference 9, the VCS EDG Exciter Magnetics Enclosure is qualified for operating in a maximum EDG room temperature of 66.7°C (152°F). The VCS EDG surge suppressor capacitors are located above the exciter power current transformers and power potential transformers, as shown in Figure 3-4, which are significant heat sources within the enclosure. The equipment specification for the VCS EDG Exciter Magnetics Enclosure (Reference 10) required the exciter equipment to be designed and rated for a maximum EDG exciter room temperature of 40°C (104°F). Based on MPRs experience with exciter cabinet temperature rise analysis and testing, properly vented exciter cabinets will maintain the internal cabinet temperature rise within 20°C during rated conditions. Therefore, it is concluded that the maximum temperature qualification for the VCS EDG Exciter Magnetics Enclosure (66.7°C) bounds the VCS application (60°C). It is noted that MPRs experience with exciter cabinet temperature rise has observed values much higher than that assumed for the CNS EDG A.C.

Outlet Box assembly, due to the significant heat generating components (i.e., transformers and rectifiers).

2079-0070-LTR-002, Rev. 3 Figure 3-4. VCS EDG Exciter Magnetics Enclosure The temperature withstand capability of the VCS EDG surge suppressor capacitors has been proven over decades of operations. Per Refence 10, VCS experiences EDG exciter continuous operation in EDG exciter room temperatures of 101°F to 111°F. Per Reference 9, VCS has monitored temperature during EDG 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months runs and collected data, which included an EDG exciter room temperature of 101°F when the outside temperature was 83°F. Per Reference 12, the VCS Diesel Generator Building Ventilation System is required to maintain the EDG exciter room temperature below 104°F (40°C). As such, the VCS EDG surge suppressor capacitors have been subjected to internal cabinet temperatures resulting from the continuous operation of the EDG exciter in an EDG exciter room temperature of 104°F (40°C). The original capacitors have remained installed at VCS, with no recorded issues related to performance or condition.

Considering the expected temperature rise within the VCS EDG Exciter Magnetics Enclosure, it is concluded that the capacitors have been subjected to steady state temperatures near 140°F (60°C).

Per Reference 13, the later version of the Type DV surge suppressor capacitors manufactured by ABB (part number 2GUS031803A1) is rated 60°C. Hitachi Energy is not able to state that the Westinghouse versions are also rated 60°C, based on changes to materials, manufacturing processes, and factories where the units were manufactured. The ABB units still use all-film metalized polypropylene dielectric material, however Hitachi Energy indicated that the properties and suppliers have changed over time. In addition, the fluid type used in the Westinghouse versions was Wemcol and the ABB versions use Faradol 810. Note that both fluids are a synthetic aromatic oil.

Surge Suppressor Capacitors

2079-0070-LTR-002, Rev. 3 The EDG surge suppressor capacitor temperature rating, derived from the VCS EDG exciter equipment qualifications and operating history, and the published ratings of similar ABB capacitors are used to establish a temperature rating for the CNS EDG surge suppressor capacitors. Although different voltage/capacitance ratings and number of poles, the VCS and CNS capacitors are very similar (both Westinghouse Type DV surge suppressor capacitors). As concluded above, the Westinghouse Type DV surge suppressor capacitors have been subjected to steady state temperatures near 140°F (60°C) with no adverse impact to performance or condition.

Although the later ABB version of the Type DV surge suppressor capacitors is not identical to the Westinghouse version, it is a similar device (both are capacitors with the same electrical output and use all-film metalized polypropylene dielectric material with fluids that are synthetic aromatic oil). Based on the above, MPR concludes that the CNS EDG surge suppressor capacitors are rated for 140°F (60°C).

The EDG surge suppressor capacitor temperature withstand rating will be established using technical inputs obtained from datasheets for similar equipment, as well as from discussions with Hitachi Energy and Vishay. In February 2019, MPR supplied spare EDG surge suppressor capacitors to VCS. These surge suppressor capacitors were manufactured by Vishay and supplied from Basler. Basler indicated that the Westinghouse part number 1NO2180A03A was obsolete and selected an alternate per Vishay type Phafso 12/0.25uF, with part number 5964-71398-02 (see Attachment 3). The Vishay type is very similar to the legacy Westinghouse type, however not identical. The Vishay type has a slightly higher voltage rating, is rated 50°C, and is physically smaller, serving as a direct replacement for the legacy Westinghouse type. Note that per Attachment 3, the Vishay type also uses an all-film metalized polypropylene dielectric material with fluids (oil). With regards to the lower ambient temperature rating provided (50°C),

Vishay stated that the losses of surge capacitors are rather low and dont lead to increased hot spot temperature against ambient temperature, so an ambient temperature range of 60 °C is not a problem for the supplied Vishay surge suppressor capacitor. Vishay also stated that the ambient temperature conditions for the Vishay type surge suppressor capacitor shall not exceed 70 °C for longer periods (qualified as days) or 85 °C for shorter periods (qualified as hours). Based on the similarity of the Vishay and Westinghouse surge suppressor capacitors, it is reasonable to conclude that the CNS surge suppressor capacitors have a temperature withstand rating of 70 °C for longer periods (days) and 85 °C for shorter periods (hours).

3.6.

CNS EDG Surge Suppressor Capacitor Design Suitability Review The maximum CNS EDG room temperature, temperature rise within the enclosure that houses the capacitor, and the capacitor temperature rating established above, will be considered to determine if the CNS EDG surge suppressor capacitor is suitable for its environment in terms of temperature.

Per Reference 1, the maximum CNS EDG room temperature during the analyzed period is expected to reach 132.8°F (56°C) when the EDG is started with one of the emergency ventilation fans out of service and the other fan remaining in the recirculation mode of operation. The temperature profile showing the maximum EDG room temperature is provided via Figure 3-5.

2079-0070-LTR-002, Rev. 3 Figure 3-5. CNS EDG Calculated Room Temperature Subsequent to completion of the analysis documented in Reference 1, Duke Energy defined additional scenarios for the EDG room heat-up. These scenarios were analyzed and documented in Reference 15. For some of the scenarios, the EDG room temperature reaches approximately140°F, as shown by the temperature profile in Figure 3-6 below.

2079-0070-LTR-002, Rev. 3 The temperature rise within the enclosure that houses the capacitor is a function of the EDG load. The EDG power cables are the primary heat source within the EDG A.C. Outlet Box Assembly. Per Reference 3, the EDG A.C. Outlet Box Assembly houses three instrument current transformers (CTs), EDG power cables, and the surge suppressor capacitor, and is 72 high, 36 wide, and 24 deep. The instrument CTs provide a low ampere output (less than 5A).

This is considered insignificant compared to the heat given off by the power cables. As shown in Figure 3-1, there are three power cable conductors per phase. Per Attachment 2, the power cables are three conductor 500 MCM. Assuming all conductor lengths of 6 feet (height of the enclosure), the temperature rise in the enclosure is expected to be approximately 4°C during the EDG mission time or 8°C when operating at the rated output of the EDG. The temperature rise in the enclosure is significantly less during the EDG mission time due to EDG loading lower than the EDG rating. The EDG rated output current is 1214A per Reference 14. Per Attachment 2, the worst case EDG loading for the mission time is approximately 730A.

The EDG is a standby system, and therefore the EDG is normally not running. The diesel building ventilation system is designed to maintain the building temperature at a maximum of 110°F (43.3°C) when the EDG is not running. With no EDG load, there is no temperature rise in the A.C. Outlet Box Assembly, thereby normally subjecting the EDG surge suppressor capacitors to 43.3°C, which is considered well below its temperature rating. Therefore, the EDG room temperature will not present any age-related degradation concerns for the EDG surge suppressor capacitors when the EDG is not operating.

The EDG is routinely operated to conduct surveillance testing. The current plant design analysis and calculations are based on an EDG room temperature that is limited to be below 120°F (48.9°C) when the EDG is operating and both emergency ventilation fans are operating as designed. Surveillance testing includes running the EDG at full load, resulting in the maximum temperature rise within the A.C. Outlet Box Assembly (8°C as assumed above), thereby subjecting the EDG surge suppressor capacitors to 56.9°C during EDG testing, which is considered below its temperature rating. Therefore, the EDG room temperature will not present any age-related degradation concerns for the EDG surge suppressor capacitors when the EDG is operating during surveillance testing.

Per Figure 3-6, the EDG room temperature remains near or below 132.8°F (56°C) for the first 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months of the 24-hour mission time. Per Figure 3-6, the EDG room temperature gradually increases to approximately 140°F (60°C) during the last 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months of the 24-hour mission time with one of the emergency ventilation fans out of service and the other fan remaining in the recirculation mode of operation. Using 4°C temperature rise for the A.C. Outlet Box Assembly as assumed above, the last 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months of the 24-hour mission time may subject the EDG surge suppressor capacitor to a steady state temperature as high as 64°C (at the end of the mission time). The 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months of operation above the steady state long time rating of the surge suppressor capacitor (60°C) is well below its temperature withstand capability (70°C for days). Therefore, the EDG room temperature will not present any age-related degradation concerns for the EDG surge suppressor capacitors when the EDG is operating during its mission time.

Design margin was considered for the capacitor suitability review. The above indicates 6°C of design margin at the end of the last hour during the mission time (ambient temperature is at

2079-0070-LTR-002, Rev. 3 64°C) at the end of the mission time, which is below the temperature withstand rating of 70°C for days. Subjecting the capacitor to a steady state temperature above its steady state long time temperature rating and below its temperature withstand ratings with margin is considered acceptable with no significant age-related degradation. This conclusion is based on the infrequent occurrence of this EDG operating condition, the magnitude of margin between the maximum EDG room temperature and withstand temperature ratings of the device (70°C for days and 85°C for hours), and the short period of time the device may be exposed to the maximum temperature above its steady state long time rating (60°C). Therefore, any potential minor changes in the calculations and assumptions for the maximum EDG room temperature and/or enclosure temperature rise (i.e., actual measurements that indicate the temperature rise in the enclosure is slightly above the assumed value), will not result in any significant degradation.

As such, the EDG surge suppressor capacitors are adequately rated for their temperature environment and maximum EDG room temperature (140°F), as required to prevent equipment failures (i.e., shorting to ground) and support the safety related function of the EDG.

4.0 Conclusion The CNS EDG surge suppressor capacitor supports the EDG safety related operation at a maximum EDG room temperature of 140°F for the infrequent and relatively short period of time considered in this evaluation.

RE: 2GUS031801A3 temperature rating questions 2GUS031803A 1 (Datasheet - EN imperial).pdf Do you see any flaws in this logic?

Yes, because materials and manufacturing processes have changed considerably.

Factories have changed multiple times since Westinghouse.

... but for 2GUS031803Al.

Attached Does that mean that the 2GUS031803Al uses the same dielectric type (all film-metallized polypropylene) and fluid type (Faradol)?

We do still use all-film PPP as insulating material - but its proprieties and suppliers have changed, which differs between units.

Also, the fluid type is different between Westinghouse units and our current ones.

In the past they were using Wemcol, today is Faradol.

We are also looking at knowing more about the 2GUS031803Al temperature rating. The attached data sheet for 2GUS031801A3 indicates 60 degrees C and we are expecting the same for 2GUS031803Al. Can we get the same type of datasheet attached for the 2GUS031803Al?

Attached and confirmed.

Also, it is not critical for our surge suppressor capacitor to work. It is more critical that it does not fail to ground and affect the output of our generator. Is there a maximum temperature that we should not exceed to prevent a catastrophic failure (capacitor shorts to ground due to high temperature) of the 2GUS031803Al?

The failure condition of a failed capacitor is generally a short-circuit condition.

You may detect if the unit begins to fail by using a current transformer - should current raise above normal value, this is a sign of elements inside the unit failing.

If you would like for the failed capacitor to not affect your generator, a monitoring CT is recommended.

Some customers also connect the capacitor through fuses, but we are against this practice as the fuses may disconnect the surge capacitor from the system and, without a monitoring system in place, your generator could be unprotected from surges.

Let me know if you have any question.

Patrick, Thanks for the detailed response. This was very helpful.

It is understood that, although the electrical output is identical, Hitachi cannot confirm if the 2GUS031801A3 and 2GUS138250A215F are fully identical to the older Westinghouse version (I.e., dimensions, mounting). We plan to do a qualitative evaluation that concludes the temperature ratings of the old Westinghouse units are the same as that of the 2GUS031801A3 and 2GUS138250A215F, based on the similarity of the design. Do you see any flaws in this logic?

Also, I did reach out to Roanna Pastor with the same question, so you may see this come your way. I am looking for another data sheet, like the one attached, but for 2GUS031803A1. This was for another plant that uses a 3 pole Westinghouse Type DV surge suppressor.

Below are the questions I asker her, with answers based on your recent feedback in red. Could you provide help with the items in yellow?

ABB Surge Suppressor Capacitor Questions At our plant we have surge suppressor capacitors per Westinghouse Part Number 1NO2180A01A, Westinghouse Type DV Surge Protection Capacitor, 7200/4160V, 60 Hz, 0.5 uF, contains WEMCOL Non-PCB combustible fluid.

It is our understanding that the 2GUS031803Al is the electrical equivalent, based on the attached cross reference chart. Is that true? Yes Does that mean that the 2G US031803Al uses the same dielectric type (all film-metallized polypropylene} and fluid type (Faradol}?

We are also looking at knowing more about the 2GUS031803Al temperature rating. The attached data sheet for 2GUS031801A3 indicates 60 degrees C and we are expecting the same for 2GUS031803A1. Can we get the same type of datasheet attached for the 2G US031803Al?

If we operate above 60 degrees C we will affect the life of the capacitor? Yes Do you have a typical derating curve for this type of capacitor for operating at temperatures above 60 degrees C and how it may affect life. Yes, provided.

What is the rated life of the 2GUS031803Al? Under normal use, life expectancy of our capacitors can go beyond 20 years Also, it is not critical for our surge suppressor capacitor to work. It is more critical that it does not fail to ground and affect the output of our generator. Is there a maximum temperature that we should not exceed to prevent a catastrophic failure (capacitor shorts to ground due to high temperature) of the 2GUS031803Al?

Hi Frank, The 1NO21080A03Awas indeed replaced with 2GUS031801A3 which was replaced with 2GUS072500A215F.

2GUS031801A3 and 2GUS138250A215F are identical - only the part number was changed.

Unfortunately, we cannot confirm that these are fully identical to the older Westinghouse version - the electrical output is identical, this is confirmed: 0.25 uF - up to 13.8 kV.

The latest version temperature range is -50 to +60C.

We do not have data for temperature above +60C, however, per experience, above this temperature, the oil molecules may start to break, and the dielectric proprieties will degrade.

Since this is a capacitor for surge application, having degraded dielectric proprieties could greatly affect the performance of the unit.

Under-normal use, life expectancy of our capacitors can go beyond 20 years.

The failure condition of a failed capacitor is generally a short-circuit condition.

You may detect if the unit begins to fail by using a current transformer - should current raise above normal value, this is a sign of elements inside the unit failing.

In any case, you should not exceed 60C as the life expectancy of the unit will suffer.

Please let us know if you have any question.

Josh, Here is the follow-up questiOns I sent to Hitachi.

Note that we no longer ne-ed any inputs from Vishay, since Hitachi's respol\\Se provided the tempttature withstand/deratirg info directly applkable to our capacitors.

I did hear back from Vishay, and they assigned my questiOn to an ergineer. So,t won't hurt to let that continue, as it could contain technical information that could be used to strengthen our conclusions.

It Is our understandiog that the 2GUS031803A1 Is the eJecttical equivalent, based on the attached cross reference chan. Is that true? Yes Does that mean that the 2GUS031803Al uses the same dielectric type (all film-metallized polypropylene and fluid type (Faradol))

We are also looking at knowing more about the 2GUS031803A1 temperature rating The attached data shHt for 2GUS031801A3 indicates 60 degrees C and we are expecting the same for 2GUS031803Al. Can we get the same type of datasheet attached for the 2GUS031803A1?

If we operate above 60 degrHS C we will affect the life of the capacitor? Yes Do you have a typical derating curve for this type.of capaotor for operating at temperatures above 60 degrHS C and how it may affect life. Yes, provided What ls the rated life of the 2GUS031803A1? Under normal use, hfe cxpec:tancy of OIX capacilorS can go beyond 20 years Also, it is not critical for our surge suppressor capacitor to work.

Hello Mr. Del Campo, thanks for your mail.

Please "nd bellow the answers.

If we operate above 50 degrees C we will aect the life of the Vishay capacitor. Do you have a derating curve for operating at temperatures above 50 degrees C and how it may aect life?

The losses of surge capacitors are rather low and dont lead to increased hot spot temperature against ambient temperature, so ambient temperature range of 60 °C is no problem.

What is the rated life of the Vishay capacitor?

Life time of capacitors is > 20 years - for surge capacitors it mainly depends on frequency and amplitude of transient voltages.

Also, it is not critical for our surge suppressor capacitor to work. It is more critical that it does not fail to ground and aect the output of our generator. Is there a maximum temperature that we should not exceed to prevent a catastrophic failure (capacitor shorts to ground due to high temperature)? We would like to show that this temperature is way above the maximum we will see in the room.

In every case the temperature shall not exceed 70 °C for longer (some days) or 85 °C for short periods (hours).

Thanks.

Vishay Surge Suppressor Capacitor Type Phafso 12/0.25uF Question Good morning Peter, Back in 2018, Vishay supplied the attached surge suppressor capacitors to Basler, and MPR (Bruce Hunt) witness testing at the factory. I believe you also interfaced with Paul Heaney.

I am looking for some help.

We are using the attached Vishay surge suppressor capacitors to replace the installed Westinghouse Part Number 1NO2180A03A, Westinghouse Type DV Surge Protection Capacitor, IL39-211-1, Fluid Volume: 1 gallon, single pole,.25 MF per pole. We believe that this capacitor is rated -50 degrees C to 60 degrees C. The Vishay capacitor is rated -25 degrees C to 50 degrees C. This meets the needs of the application, but the temperature in the application may be increasing above 50 degrees C in new EDG room calcs being developed. So we have the following questions:

If we operate above 50 degrees C we will aect the life of the Vishay capacitor. Do you have a derating curve for operating at temperatures above 50 degrees C and how it may aect life?

What is the rated life of the Vishay capacitor?

Also, it is not critical for our surge suppressor capacitor to work. It is more critical that it does not fail to ground and aect the output of our generator. Is there a maximum temperature that we should not exceed to prevent a

4 catastrophic failure (capacitor shorts to ground due to high temperature)? We would like to show that this temperature is way above the maximum we will see in the room.

Thanks in advance for any help you can provide.

CNS EDG Room 2A Heat-up Analysis - Interim Results for New Cases

Dear Mr. Cox:

MPR recently completed a heat-up analysis of the Catawba Nuclear Station (CNS) 2A Emergency Diesel Generator (EDG) room to assist Duke Energy in evaluation of a past operability concern associated with the 2A EDG. Due to a faulty temperature controller for 2A emergency ventilation fan 2A1, the fan would have remained in recirculation mode if called into service after an accident which requires operation of the EDG. As a result, the fan would not have provided a normal amount of forced cooling and the EDG room temperatures would have increased. There is a concern that the temperature could have challenged the operability of the equipment in the EDG room.

The completed MPR analysis included multiple cases to assist with the Duke Energy operability and PRA evaluations. Some cases used the actual ambient temperature time histories during the period of degradation, simulated the heat-up of the room, and determined the maximum temperatures that would have been reached at the end of 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of emergency operation.

Other cases calculated the maximum constant ambient temperature that would result in the EDG room temperature reaching the limit of 131°F in 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . The limit of 131°F was set by Duke Energy based on evaluation of components in the room that need to remain functional.

Duke Energy has recently been able to demonstrate that the components that were the drivers for the 131°F limit could tolerate higher temperatures, up to 145°F. Hence, the 131°F limit is conservative and higher temperatures in the EDG room are acceptable (e.g., 139°F or higher).

Therefore, Duke Energy requested that MPR analyze additional cases and calculate the new maximum ambient temperature that will result in the room reaching the new higher limits in 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

MPR has completed the analysis of the newly defined cases to develop preliminary results. The analysis inputs and results have been checked and reviewed. The documentation of the results in MPR calculations is currently underway and will require several weeks to complete. To facilitate progress of the Duke Energys PRA evaluation and timely communication of the findings to the NRC, the preliminary results are provided in this letter.

MPR CELEBRATING 60 YEARS

Mr. Trey Cox 2079-0070-LTR-003, Rev. 0 July 2, 2024 Note that the results can only be considered final once all the analysis calculations are signed by MPR personnel (preparer, checker, reviewer, and approver), and the Duke Energy Owners review is complete. Until that time, these results should be treated as high-confidence but preliminary results.

Results The new analysis cases defined by Duke Energy are summarized in Table 1. For all cases, the 2A2 fan is out of service and the 2A1 fan remains in the recirculation mode. All cases use the same heat load in the EDG room. The parameters that vary between the cases are as follows:

Selected EDG room temperature limits (131°F, 139°F, and 145°F).

For some cases, the outside ambient temperature is assumed to remain constant and equal to the daily maximum temperature. For other cases, a bounding two-value step function is used to capture the diurnal variation of temperature in a 24-hour period.

For some cases, no operator action is assumed to take place. For others, operator action to open the stairwell doors AX306A and AX306B is credited. The action to open these doors are assumed to be completed 60 minutes after the EDG room reaches the 110°F room temperature alarm.

Table 2 provides the calculated maximum outside temperature to achieve the EDG room temperature limit for each case in this parametric study. A few relevant observations from the results in the table are as follows:

Mr. Trey Cox 2079-0070-LTR-003, Rev. 0 July 2, 2024 For a given EDG room temperature limit, use of a two-value step function instead of a constant ambient temperature increases the maximum acceptable ambient temperature by slightly less than 2°F.

Increasing the limiting temperature in the EDG room has significant benefit. For example, raising the limit by 14°F from 131°F to 145°F increases the acceptable maximum ambient temperature by slightly more than 20°F.

Compensatory action to open the stairwell doors provides a source of cooling. As a result of this action, the maximum acceptable ambient temperature increases by slightly over 3°F in comparison to no such action.

EMERGENCY DIESEL ROOM 2A CABLE & WIRING TEMPERATURE EVALUATION Field Cables (Power, Control, Instrumentation)

The power cables purchased and installed in Emergency Diesel Room 2A are crosslinked polyethylene (XLPE) or Ethylene Propylene Rubber (EPR) insulation (CNS-1354.01-00-0001 & CNS-1354.01-00-0003). XLPE and EPR cables are manufactured to operate continuously at a maximum conductor temperature of 90°C, or during emergency operation at 130°C (ANSI/NEMA WC70/ICEA S-95-658-2021, Appendix C ).

Operation during emergency overload temperatures shall not exceed 100 hours0.00116 days 0.0278 hours 1.653439e-4 weeks 3.805e-5 months in any twelve consecutive months, nor more than 500 hours0.00579 days 0.139 hours 8.267196e-4 weeks 1.9025e-4 months during the lifetime of the cable. XLPE and EPR insulation are categorized as thermosetting material. Thermosetting material will age more rapidly in response to higher than rated temperatures. As the insulation experiences elevated temperatures, it can soften, but does not melt (EPRI Power Plant Electrical Reference Volume 4, Wire and Cable, 12/1991 Edition).

Because the thermosetting materials retain their physical integrity at elevated temperatures, they are not expected to short or ground due to elevated operating temperatures.

The cable and wiring temperature ratings are associated with the maximum allowable conductor temperature, which is a function of the amount of current the cables are carrying, and ambient temperature. While the actual conductor temperatures are unknown, this evaluation conservatively assumes that the cables are operating at their maximum allowable design temperature of 90°C (194°F).

ICEA standards assume a 40°C ambient (for cable in air), which allows a 90°C - 40°C = 50°C rise in conductor temperature. License Renewal Evaluation DPS-1274.00-00-0006, Rev. 3, documents bounding service condition values for Catawba & McGuire, including both ambient temperature and ohmic heating (heating due to carrying current). Table 4-3 documents a design temperature of 110°F (43°C) plus ohmic heating of 162°F (72°C). This is a 29°C (72°C - 43°C) temperature rise, well below an allowable 50°C rise; therefore, assuming a maximum cable operating temperature at 90°C is very conservative. Furthermore, the cables can operate continuously up to their emergency operation temperature of 130°C (266°F) for up to 100 hours0.00116 days 0.0278 hours 1.653439e-4 weeks 3.805e-5 months (for cable in air), which provides additional margin above their continuous operation rated temperature.

OAC data of Emergency Diesel Room 2A temperature from November 2023 to January 2024 varied from ~ 80°F to 97°F, with temperatures for the most part below 90°F. As previously discussed, the cables can tolerate temperatures up to 130°C (266°F) for 100 hours0.00116 days 0.0278 hours 1.653439e-4 weeks 3.805e-5 months during any twelve-month period. The temperature profile during the postulated situation ranges from a maximum room temperature of 97°F (32.2°C) to 139°F (59.4°C) over a 24-hour period. The change from this room temperature value to the maximum expected temperature of 139°F is gradual over the 24-hour period. Even if it is conservatively assumed that an ambient room temperature 139°F is sustained for the full 24-hour period, the cable rating of 90°C (194°F), as well as the emergency operating temperature of 130°C (266°F), provide substantial margin. Consequently, the power cables would still be able to perform their required design functions at the projected worst-case ambient temperature during the postulated period at 139°F (59.4°C).

Since I&C cables have much lower ohmic heating and subsequent temperature rise, they are enveloped by the preceding power cable evaluation.

EMERGENCY DIESEL ROOM 2A CABLE & WIRING TEMPERATURE EVALUATION Internal Hookup Wiring Vendor control wiring in Diesel Generator Control Panel 2A (2DGCPA) is a minimum # 14 AWG SIS Type wire (CNS-1301.00-00-0002, Rev. 4; CNM 1301.00-0058.001, Rev. 4). Type SIS wire has an operating temperature of 90°C and is insulated by flame-retardant thermoset insulation (National Electrical Code, 2023 edition). Vendor wiring in Diesel Engine Control Panel 2A (2DECPA) is minimum # 14 AWG wire with 105°C insulation (CN -2777-01.01, Rev. 33, Note 7).

Duke-supplied wiring meets Electrical Installation Spec CNS-1390.01-00-0017, Rev. 22. This specification requires wiring in electrical cabinets & panels to be # 16 AWG wire, unless otherwise specified.

Purchasing Specification CNS-1354.04-00-0006, Rev. 0 (Shielded and Unshielded 600 Volt Switchboard and Hook Up Wire) applies, which requires wiring to be able to withstand an ambient temperature of 200 F for 100-days for Loss-of-Coolant Accidents (LOCA) & Main Steamline Breaks (MSLB). Though the Emergency Diesel Rooms are not exposed to LOCA or MSLB conditions, the same wire is used in the Emergency Diesel Rooms.

Assuming an ambient room temperature 139°F in the Emergency Diesel Room 2A for 24-hours, and based upon the significant positive margin in the wiring insulation temperature ratings, along with other information above, the internal cabinet wiring in the Emergency Diesel Room is not expected to fail during the evaluation period; therefore, the control wiring in Emergency Diesel Room 2A is capable to perform its required design functions at the projected worst-case ambient temperature during the postulated situation of 139°F (59.4°C) for a 24-hour period.

1. Problem Statement The scenario described in EC 424080 is that during a postulated event, due to 2A2 VD fan out of service and 2A1 VD Fan operating in recirculation mode, it was determined that temperatures in the 2A EDG room could exceed the design maximum temperature of the 2DGCA battery charger of 55°C (131°F) as stated in CNM 1356.08-0003.001, Section 1. During the time periods stated in EC 424080, it is postulated that, worse-case, the design maximum temperature would be reached in approximately 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months following a diesel start and temperatures would increase to a temperature of 60°C (140°F) at the end of the 24-hour period.

2. Purpose The purpose of this evaluation is to assess with reasonable assurance, the ability of the 2A EDG battery, 2DGBA, is adequately sized to supply the necessary equipment loads during the prescribed duty cycle (LOCA and/or Blackout loads) for a total of fourteen (14) hours, in the event that 2A Battery Charger fails after 2A Diesel Room temperature rise above the chargers maximum design temperature of 55°C (131°F).

4. Assumption:

2A EDG 2DGBA was fully re-charged following the initial two-hour coping duration and prior to the 2DGCA battery charger exceeding maximum design temperature at approximately 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months into the event.

This evaluation will use the LOCA/Blackout duty cycle loads defined in CNC-1381.05 0050 R12 for the initial two hours followed by steady-state loading, assumed to be equal to the 12-119-minute duty cycle, for an additional twelve (12) hours. The entire duty cycle is this evaluation is fourteen (14) hours.

2A Diesel Room will not exceed 60°C (140°F) during the 24-hour period. IEEE Std 485-1983, does not have a temperature correction factor for 140°F. The highest temperature available on the temperature correction factor chart is 125°F (0.850).

As shows in Attachment 4, when the temperature increase the correction factor multiplier decrease; therefore, a correction factor of 0.850 (125°F) is considered conservative and will be used in this evaluation.

Conservatively added an Aging Factor of 1.25. As shown in Attachment 3, 2DGBA continues testing over 100% capacity at its current age with the last test performed on 7/31/2023.

Conservatively added a Design Margin of 1.15 as recommended per IEEE Std 485-1983.

5. Methodology The methodologies established in IEEE 485-1983 (Battery Sizing) as described in CNC-1381.05-00-0050, R12 are used to determine the capacity of 2A EDG battery 2DGBA and the terminal voltage (IEEE 485-1997).

This evaluation duty cycle is based on the LOCA/Blackout duty cycle defined in CNC-1381.05-00-0050, R12 with an additional time period of twelve (12) hours.

The new time period assumes to be equal to the 12-119-minute duty cycle loads for twelve (12) hours. The total duty cycle is fourteen (14) hours.

This is addressed by multiplying the computed cell size or number of plates by an adjustment factor that will consider this temperature. This factor is a function of the discharge interval. The values for the various time interval are tabulated in Table 2.

Table 2 list the Kt and Rt factors for GNB NCN-9 lead calcium battery (2DGBA) for the various time intervals required for this evaluation, which are used to compute the Kt and Rt capacity factor methods. The Kt and Rt factors for the GNB NCN-9 lead-calcium battery (2DGBA) for the various time intervals that are not listed in the manufacturer data sheets were linearly interpolated from given values.

The cell sizing worksheet shown in Table 3 and Table 4 use the equations below to size the GNB NCN-9 lead calcium battery (2DGBA).

The battery (2DGBA) terminal voltage profile in this evaluation is calculated by the method described in IEEE 485-1997 using the curves in Attachment 1. The battery profiles consider one cell jumpered, load growth and the cell jumper resistance (as described in CNC-1381.05-00-0050). Refer to Table 5 for the battery terminal voltage profile.

Rrte5 24QR1 RevR Alff There was another type o that just got corrected, attached be one to use. The 8hr to 1.84vdid not match to the published cutsheet for this rating.

There was testing to 1.85v as well as various other end voltages that isnt listed and probably how some of the contusion started when information was transposed onto the extended rate sheet.

This information was 1st provided by Stryten in 2018 using NCN 17 and NCN 35 cells to populate the extended rates, the person that lead that projec t at the time is no longer with Stryten and was never followed up on until now based on your inquiry.

The Design product engineer from Stryten that we deal with consistently, while he was involved with performing the testing on this to establish data points, but he was not involved with providing the extended rates as you see in the attached, never the less he was up half the night digging through all the old files on this double checking everything to confirm the accuracy ot the extended ra tes.

All, Apologies for the contusion, but the attached is corrected revised extended rates we just received during the night from our point of contacts atStryten (formally GNB).

The rates listed that was originally for 1.85vpc is in fact tor 1.84vpc. Was noted as a type-o when Stryten created the extended rates and was never followed up on until your request.

EVALUATION OF CTs IN D/G-2A AC OUTLET BOX ASSEMBLY Prepared By: Thomas E. Robinson Date: 4/25/2024 The concern with the CTs in the D/G-2A Generator Outlet Box Assembly is proper operation in a higher than normal Diesel Room temperature. These CTs provide the neutral-side input to the 87G Generator Differential protection. The line-side input to the 87G comes from CTs in the Switchgear Room. The 87G trip is active during emergency operation of the D/G; therefore, it is imperative that the 87G does not trip if temperature in the Diesel Room causes the CT output to change, causing an imbalance, thus actuating the 87G Relay.

The CT Rating Factor (RF) provides the CT overload capability, or it expresses the amount of current the primary of the CT must not exceed to prevent the CT from exceeding its allowable temperature rise. As long as the CT is operated within the RF value, accuracy of the CT is not affected, and there is no concern with tripping the 87G relay with the CTs in-question operating at a higher temperature.

The CTs are ITE MCB-5A:

Ratio = 1200:5 RF = 1.33 @ 30°C Diesel Room temperature is analyzed to be 132.8°F from vendor calculations. Diesel Room temperature (TDGRoom) will be rounded to 140°F.

Assume a 10°F temperature rise in CT cabinet compared to ambient room temperature.

TNEW = TDGRoom + 10°F = 140°F + 10°F = 150°F (65.6°C)

RFNEW = {[(85 - TNEW)/55]*RFRATED2}1/2 = {[(85 - 65.6)/55]*(1.33)2}1/2 = 0.79 ICTmax = (ICTrated)*(RFNEW) = 1200*0.79 = 948 A From CNC -1211.00-00-0148, the maximum load occurs during B/O-LOCA with a load of 4432 kW, which occurs at 4165 V & 59.93 Hz (steady-state voltage and frequency from recent D/G-2A trending data and instrument accuracy considerations; reference CNC -1211.00-00-0148).

Ploca@V&F = 4432 kW (@ 4165 V & 59.93 Hz)

Power Factor (PF) = cos Calculation CNC -1211.00-00-0148, Appendix A documents expected loading during the evaluation period. Per this calculation, the worst-case power factor occurs during Blackout conditions compared to LOCA conditions; therefore, power factor value will be calculated from the Blackout values in CNC -1211.00-0148. Grand Total Equivalent Loading (p. A22) is 4597.73 kW and 5245.49 kVA. Since power factor (PF) = kW/kVA, PF = 4597.73 kW/5245.49 kVA = 0.877. The power factor of 0.877 would cause increased current from the generator passing through the CTs. A power factor value of 0.85 will be assumed since this will provide a more conservative value compared to 0.877.

EVALUATION OF CTs IN D/G-2A AC OUTLET BOX ASSEMBLY Prepared By: Thomas E. Robinson Date: 4/25/2024 P (in kW) = (3)VI(cos)/1000 I = (P*1000)/[ (3)V(cos)] = (4432*1000)/[ (3)(4165)(0.85)]

I = 723 A Since 723 A < 948 A, there is no concern with the CT exceeding its temperature rating.

ILl]\\.""EAR REACTOR E VALCA TIOK

!Temperature limit is not referenced in our design documentation; however, N""E'.\\IIA Standard ST 20 for Dry-Type

!Transformers for General Applications is referenced in the manufacturer's documentation for the linear reactor.

!The lowest rated winding insulation systems specified in 1'-'EYL.<\\ S T-20 is 105°C. A winding rated for 105°C (221°F) per

~""E:\\1A ST-20 is base.don a 40°C ambient with a Hottest-Spot Temperature Rise of 65°C (40°C + 65°C =105°C). If the

~bient is 140°F, or 60°C, the maximum temperature-rise all owed is 105°C - 60°C = 45°C.

!The most-recent thermography data w as taken on 9f23i2022. The thermography results are stored at the following location:

!From review of the thermography data from 9 '23/2022 for D. G-2A, the Linear Reactors were operating at a ma,.imum emperature of 167°F (75°C). Diesel Room 2A temperature at the time per OAC data was 86°F (30°C). The temperature rise

~or the Linear Reactors is calculated as follow:

75°C - 30°C = 45°C temperature-rise

.<\\ssumptions:

1. The linear reactors are assumed to be manufactured at the lowest temperature r ating specified in N""EYL.<\\ Standard ST-

20.

2. The same temperature rise occurs at different ambient temperatures.

3. Instead of using the r esults in kW from Calculation CKC -1211.00-00-0148, the,*alues in loading table for Grand Equivalent Total Loading of Appendix A,.,.rn be used since these values are higher than the results of the calculation, W..1tl ct1c. Llu:1d'u1e, 1nu1 e t.:OU!>C'l v citiv e.

4. Temperature-rise when the OAC data was taken on 9l23!2022 occurred at full-load and 0.98 lagging power factor.

Calculation CNC - 1211.00-00-0148, Appendix A, Rev. 0 documents expected loading during the evaluation period.

Per this calculation, the worst-case power factor occurs during Blackout conditions compared to LOCA conditions.

Grand Total Equi,*alent Loading (p. A22) is 4597.73 kW and 5245.49 k\\.A. Since power factor (PF) = k\\\\.lkVA, PF=

4597. 73 kW/5245.49 kV A = 0.877. The power factor of 0.877 would cause increased load (and heat) passing through the reactors; however, the lower k\\V load would tend to counteract this increase. An expected load of 4597.73 k\\V translates to 80% of the derated 5750 k \\V load, or 66% of the machine rated load. It is assumed that these differences between increased power factor loading and decreased k W loading will counteract each other, and the results of this calculation are not impacted.

~tan ambient of 140°F (60°C) and a 45°C temperature rise, the linear reactor temperature is calculated as follows:

60°C - 45°C = 105°C reactor temperature Since an ambient room temperature of 140°F (60°C) results in a linear reactor temperature 105°C, it can be concluded that the

!maximum allowable room temperature is 140°F (60°C).

1 2A D/G SHUTDOWN DE-ACTIVATION RELAY (R10)

Cutler Hammer/Eaton D26 Tommy Robinson Bryan Grau Yes Relay failure will enable Non-Emergency Trips (assuming R9 also fails). Power to the Non-Emergency Trip Panel A/C Cooling Unit will fail on a LOOP. 120 VAC power to Non-Emergency Trip Panel is on non-safety inverter power. Power will still be available to the panel on a LOOP-Only, in this case, but not to the A/C Unit. On LOOP-LOCA, batteries will eventually deplete, and power to the Non-Emergency Trip Panel will be lost, immediately enabling a lube oil pressure trip. If both R9 & R10 fail, a non-emergency trip will occur when the first of either a card failure due to loss-of-cooling to the panel, or the panel loses power when the batteries for the inverter fail.

Since relays have an operating range of -40C to +65C (+149F), at an ambient temperature of 139 F, and assuming a 10 F rise in 2DECPA where R10 is located, the relay is not expected to fail; thus, non-emergency trips will remain blocked, and D/G operation is not affected.

1 2A D/G SHUTDOWN DE-ACTIVATION RELAY (R9)

Cutler Hammer/Eaton D26 Tommy Robinson Wally Green Yes Relay failure will enable Non-Emergency Trips (assuming R10 also fails). Power to the Non-Emergency Trip Panel A/C Cooling Unit will fail on a LOOP. 120 VAC power to Non-Emergency Trip Panel is on non-safety inverter power. Power will still be available to the panel on a LOOP-Only, in this case, but not to the A/C Unit. On LOOP-LOCA, batteries will eventually deplete, and power to the Non-Emergency Trip Panel will be lost, immediately enabling a lube oil pressure trip. If both R9 & R10 fail, a non-emergency trip will occur when the first of either a card failure due to loss-of-cooling to the panel, or the panel loses power when the batteries for the inverter fail.

Since relays have an operating range of -40C to +65C (+149F), at an ambient temperature of 139 F, and assuming a 10 F rise in 2DECPA where R9 is located, the relay is not expected to fail; thus, non-emergency trips will remain blocked, and D/G operation is not affected.

3 2A DIESEL GENERATOR CHARGER AMETEK SOLID BCS 12075 Aaron Beekman Jim Glasser Yes The design allowable ambient temperature rating accounts for the charger being continuously loaded to at least at the nameplate value of 75 amps (may be up to the current limit value of 86 amps). It is expected that the actual charger average load current will be less than the namplate rating under design basis conditions; therefore, there is likely some margin above the design allowable ambient temperature rating. Additional analysis will be required to evaluate what margins may be available.

With the 800 A breaker, this is only 13% of rating. Using engineering judgment, there is enough margin to safely state that operation at the higher temperature will not impact the current-carrying ability of the breaker.

1 2A DIESEL ENGINE DELAVAL/TRAN DSRV-16-4 Trey Cox Jim Glasser Yes There are no concerns with 2A EDG room exceeding 120F when it comes to 2A Diesel Engine. During normal operation the engine itself operates at approximately 150F. From OEM Shop testing, approximately 2% of heat loss from the engine is due to radiant heat. The rest of the heat generated by the engine is removed via KD and LD to RN. The environmental conditions of the 2A EDG room would have negligable impact to overall 2A EDG temperaure. The most temperature dependedent component on the 2A EDG is the pre-turbo exhasut temperature which must be limited to less than 1200 degrees. During summer at full load the pre-turbo exhast temperaure reaches approximatley 1050F. There is 150F margin remaining to the 1200F limit. JDG comments: Concur with reviewer. Exhaust temperatures are primarily influenced by combustion air intake temperature, which is primarily affected by outside air temperature. Consequently, exhaust temperatures would not be expected to be appreciable affected by room ambient temperature.

Maximum room temperature at the time of thermography was 103 deg F. Maximum SCR current was 63.3 A (SCR1) at no-load (SCR currents are higher at no-load, and therefore, more conservative for this evaluation). With a room temperature of 150 F, SCR temperatures will be higher, but not expected to exceed 239 F, the derated SCR maximum case temperature (based on ~ 65 A @ 90 degree conduction angle). Margin when the thermography data was taken was 239 - 153.7 = 85.3 F. The expected change in room temperature is 150 F - 103F = 47 F. The SCR temperature margin, as calculated above, is 85.3 F. Based on engineering judgment, it is not expected that SCR temperature would have exceeded 239 F since the expected change in room temperature is less than that change in SCR temperature margin (47 F < 85.3 F). Furthermore, SCR degradation is gradual, provide the maximum temperature rating is not exceeded; however, it is expected that the service life of the SCRs would have reduced with operation at the elevated temperature. Failure of the SCRs is not expected during the 24-hour mission time.

Average Room Temperature at the time was 103 F. With a room temperature of 150 F, diode temperature will be higher, but not expected to exceed 320 F, the derated diode maximum case temperature (based on 120 A @ 60 degree conduction angle). Margin when the thermography data was taken was 320 - 192.7 = 127.3 F. Based on engineering judgment, it is not expected that diode temperature would have exceeded 320 F based on the margin available, plus the fact that D/G-2A would be at a reduced load compared to load on the diesel during the 24-hour run when the thermography data was taken, which would have reduced current through the diode, reducing diode operating temperature. Furthermore, diode degradation is gradual, provide the maximum temperature rating is not exceeded; however, it is expected that the service life of the diodes would have reduced with operation at the elevated temperature. Failure of the diodes is not expected during the 24-hour mission time.

3 DIESEL GENERATOR CONTROL PANEL FANS (2DGCPA) Westinghouse BAB2020 Wally Green Bryan Grau Yes Section 4.1.3 of CNC 1381.05-00-0279 identifies that BAB breakers are rated for a normal ambient maximum of 40C (104 F), and that derating is required for higher temperatures. of CNC 1381.05-00-0279 contains derating information provided by Eaton for the BAB breakers. The breakers are qualified to operate up to a maximum ambient temperature of 80C (176F) when derated from a nominal 20 amps (at 40C) to 10.0 amps.

The normal operating current for the fans is 4.8 amps, which is less than the maximum allowed current of 10.0 amps. Assuming that cabinet temperature rise is 10F, the maximum allowable ambient temperature in the diesel room for BAB breakers is 166F (74.4C).

Fans are not required for AVR operation for ambient temperatures up to 120°F per evaluation in EC416966. EDG VR evaluation should address operation at higher temps.

The fan is not required if the room is less than or equal to 120 deg F.

1 2A D/G ENG LUBE OIL INLET PRESSURE ROSEMOUNT 1153GB7P Trey Cox Jim Glasser Yes JDG comment: Concur with the qualified life statement made by the reviewer; however, temperature effects on transmitter setpoint should also be considered. Per data on pdf page 572 of CNM 1210.04-0262, the total error (span and zero) for a range code 7 transmitter is +/-1.25%

span/100°F. Per EDB, the span is 100 psig; therefore, the temperature effect is +/-1.25 psig/100°F. I don't have access to the setpoint calc., so I'm not sure what was assumed for max. temperature in terms of incorporating the temperature effect in the loop undertainty (SRSS) calc. (assuming one exists). Assuming a reference temperatue of 120°F, the additional error from the temperate effect alone at 150°F would be +/-0.375 psig [=(150-120)*1.25/100]. The effect on overall error would be less when all of the other error terms (drift, accuracy, etc.) are factored in. The net worst-case impact would be to slightly increase the potential for a premature emergency trip; however, considering the normal operating lube oil pressures (i.e. >40 psig), the effects are deemed neglible.

TC Comments to JDG Comments: CNC 1210.04-00-0073 assumes 120F which creates an error for the temperature term of 1.65% of span. using 167F vs 120F takes the uncertainty for temperature to 2.94% span which equates to.294 psig. This additional uncertainty is negligible considering normal operating pressure (>55psig) is 20 psig greater than low low lube oil pressure trip setpoint of 35psig CNM 1210.04-0262.001 Figure 1 167 N/A CN 2

Temperature Rating above 150 deg F Based on field walkdown this is a V27S root valve that is suitable for 250 deg F at 300 psig.

Valve tag in the field shows 2YDIV7891. Previous EC (CD200107) was completed to change nomenclature from 2RNIV7891 to 2YDIV7891, however in this case the field tag was updated but the EDB record for 2RNIV7891 was not retired. EAR 02509059 has been generated to resolve the EDB discrepancy.

Valve Model type can be a 2S,4S or a 5S bases on CN-1499-MI12-04. Based on CN-1499-MI.12.00 the 5S is limiting and has a maximum temperature of 250 deg F at 300 psig.

Per CNS-1574.RN-00-0001, with 2RN232A open and incapable of closing, operability of the RN system and DG2A is not affected. Valve 2RN232A is closed during normal unit operation to isolate RN flow to diesel generator engine jacket water cooler 2A, since the diesel generator is not in operation.

2RN232A will open during the first 76 seconds of an accident/diesel start. Therefore any elevated room temperature will not adversly impact 2RN232A.

CNM 1301.00-0450.001 CNM 1301.00-0445.001 CNEE-0220-07.01-01 N/A On a D/G Emergency start, the K1 Contactor Reset Coil energizes immediately to provide a permissive to the FF Contactor, and to unblock the PPT/PCT outputs for generator field excitation. Immediately upon energizing the Reset coil, Contacts 13,14 open to remove power from the coil. The contactor stays latched in this state until shutdown. On shutdown, the Set Coil energizes to place the contactor in the shutdown state.

Initial room temperature is not above the component ratings. When room temperature exceeds the component ratings, the K1 Contactor is latched in the reset (latched) state throughout the mission time. Based on how the contactor operates, exceeding the ratings of the Latch Block

& Aux Contacts is not expected to degrade the function of K1.

The Max temperature Column "AC" that is used to sort results was dentoed as N/A due to the function of the component being completed early in the EDG start, and hence the component would not have to actuate when the room temperature is high.

During the dates of 8/2/2022 to 1/3/24 the RN system was NOT in Single Header Operation. Therefore, the WN system is not needed. Reference CNS-1609.WN-07-0001, UFSAR Section 9.5.9.1 Additionally, as documented in CNC-1223.59-07-0006, the WN pumps are not required to operate to maintain EDG operability. There is sufficient capacity in the WN sump and pit to capture any expected leakage, or there is sufficient time for postulated inputs from YM into the sump to be isolated. The time to isolate leakage from YM assumes the 2WNLS5030 operates correctly. As such 2WNLS5030 will be evaluated for max allowable temperature.

For the purposes of this evaluation, the level switch has to operate for 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months for the 2A EDG to meet its PRA mission time. Average 2A EDG room temperature is 90°F so there is no expected degradation to the level switch due to normal standby ambient temperature of 2A EDG room. Although the EQ testing was performed at 212°F, Engineering will document a max allowable temperature of 150°F for conservatism.

Based on the completed EQ testing, there is reasonable assurance that 2WNLS5030 can operated for at least 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months at a 2A EDG room temperature of 150°F. Reference CNM 1210.04-0369.001 CNM 1210.04-0369.001 150 N/A CN 2

CT: GE Model 5RBT-201 Ratio = 200:5 From the CT ratio, the CT is rated for a primary current of 200 A, which produces a secondary current of 5 A. Per an email from a GE rep dated 4/23/2024 (attached), the maximum allowable ambient at the CT (New Amb) can be calculated using the below formula.

( )2

( @ 30)2

= (85 )

55 In order to calculate "New Amb", we must first determine the maximum allowable rating factor (New RF at New Amb).

The subject CTs measure Voltage Regulator rectifier diode current of Diodes CR2, CR4, &

CR6. The CT current is used by the Voltage Regulator to generate the firing currents for the SCRs to control generator output voltage.

The current diodes on D/G-2A were installed and diode currents measured on 2/3/2021 per PM W/O 20363121-04. Full-load current for Diodes CR2, CR4, & CR6 are as shown below. A diode current of 110 A encompasses these values. This data was taken with D/G-2A at a full-load of ~ 5750 kW @ 0.98 power factor (PF) lagging. The worst-case loading calculated for the evaluation period is documented in CNC-1211.00-00-0148 and occurs under LOCA Loading compared to Loss-of-Offsite Power (LOOP) loading, which is 4432 kW. This load is lower than the 5750 kW that occurs when diode current readings are taken; therefore, the diode currents 2/3/2021 will be used since it encompasses the diode currents that would occur if D/G-2A would have operated during an event during the evaluation period.

CT Primary Current = 110 A Maximum Allowed Rating Factor =

110 200 = 0.55 Using the maximum allowable rating factor of 0.55 and an RF at 30 of 1.0, we can now determine the corresponding maximum allowable ambient temperature inside the Diesel Generator Control Panel (New Amb).

(0.55)2 1.02

= (85 )

55

= 68.36 = 155 Assuming that temperature rise inside the Diesel Generator Control Panel is 10, it can be concluded that the maximum allowable Diesel Room ambient is 145.0.

image.png image.png image.png image.png Hi Bryan, As discussed on the phone, lets go ahead and assume a 65C ambient.

The 200:5 has a rating factory of 1.0 @ 30°C.

At 65°C (149°F) average ambient temperature the rating factor would be about 0.6 @ 65°C.

Ryan, The 65.6C (150F) is the maximum for the 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months period, but we are using that as a bounding value for the entire 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months period to be conservative. This temperature is the result of running one of our Emergency Diesel Generators for a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months period of time with no ventilation in the room.

Therefore, temperature in the room increases throughout that 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months period.

EXT: RE: [EXTERNAL] Duke Energy - 5RBT-201 The 131F ambient temperature is located outside the enclosure. Our measured temperature rise inside the enclosure is approximately 10F. Would you be able to provide the de-rating factor for an ambient of 61C? At 61C, RF is at about 0.7.

We have a similar question with a separate GE transformer (9T28Y5611) which the label plate shows has a temperature rise of 80C. Do you have any literature on the 9T28Y5611 and what its rated ambient temperature is? Ive attached a picture. Unfortunately, I do not have any information on this transformer Sincerely, Bryan Grau, P.E.

Bryan, The 5RBT-201 has a rating factory (RF) of 1.0 @ 30°C (86°F).

At 55°C (131°F) average ambient temperature the RF should be de-rated to 0.75 @ 55°C.

Hope this helps.
