On August 14, 2017, the NRC issued Inspection Report 05000461/2017009 to Exelon Generation Company, LLC (EGC). The Inspection Report identified a preliminary finding defined as an Apparent Violation (AV) of 10 CFR 50, Appendix B, Criterion Ill, "Design Control." The AV was classified as self-revealing, low to moderate safety significance (White). The AV is related to the failure to evaluate the change in the actual drop-out relay voltages for the Division 1 Emergency Diesel Generator (EOG) room ventilation fan resulting in the EOG being declared inoperable. The Inspection Report provided EGC the option to attend a Regulatory Conference or submit the EGC position on the finding, in writing, within 40 days of the date of Reference 1. Additionally, the letter required a ten-day response to notify the NRC of the intended response. On August 23, 2017, EGC submitted the required ten-day response to notify the NRC that a 40-day written response would be submitted to provide EGC's position on the finding (Reference 2). The 40-day response is provided in the Attachment, "Exelon Generation Company's Position Concerning the Significance of Apparent Violation EA-17-098."

September 18, 2017 U.S. Nuclear Regulatory Commission Page2 The Attachment to this letter contains a description and conclusion of the additional analysis performed to evaluate the survivability of equipment in the Division 1 EDG room following a failure of the EDG ventilation fan 1VD01 CA. The additional analysis is enclosed with this letter. EGG recognizes that a performance deficiency occurred and does not dispute the AV or the assigned cross-cutting aspect. However, after reviewing new information provided herein, EGG has reassessed the safety significance and has concluded that the finding has very low safety significance (Green}. The very low safety significance is based upon additional analysis and factors beyond those initially provided to the NRC for use in assessment of the significance of the issue. EGC performed an evaluation to document reasonable assurance of continued operation of the EOG for 24 hours following a start failure of the EDG ventilation fan. The margins to the survivability limits for critical devices for the bounding case of a. Large Break Loss of Coolant Accident I Loss of Offsite Power with the doors closed (i.e., no operator action} scenario increased from the initial evaluation provided during the inspection period to the enclosed evaluation from ~ 11°F to~ 37°F. The margin was calculated in a manner that addresses uncertainties, and therefore provides "reasonable assurance" of EDG operation for the PRA mission time. With reasonable assurance of operation, EGC reviewed IMC 0609, Appendix A, "The Significance Determination Process (SOP} for Findings at Power," Exhibit 2 and could answer all the questions "No". EGC therefore concludes that the finding's significance meets the definition of having very low safety significance and should be characterized as Green. There are no regulatory commitments contained in this letter. If you have any questions, please contact Mr. Dale A. Shelton, Regulatory Assurance Manager, at (217) 937-2800. Theodore R.

Attachment Exelon Generation Company's Position Concerning the Significance of Apparent Violation EA-17 -098

Attachment Exelon Generation Company's Position Concerning the Significance of Apparent Violation EA-17-098 1.0 OVERVIEW NRC Inspection Report 05000461/2017009 documented a finding that has preliminarily been determined to be White, a finding with low to moderate safety significance, with an associated apparent violation of 10 CFR Part 50, Appendix 8, Criterion Ill, "Design Control," and Technical Specification (TS) 3.8.1, "AC Sources-Operating." This finding is associated with the failure to evaluate the change in the actual drop out voltages for replacement relays associated with the Division 1 Emergency Diesel Generator (EOG) room ventilation fan. Specifically, Engineering Changes (EC) 330624 and 366624 failed to evaluate the change in the actual relay drop out voltages on the operation of the Division 1 EOG room ventilation fan circuitry prior to replacing the X2 and X3 relays on May 18, 2016 and January 2008, respectively. The failure to properly evaluate the effects of the drop out voltages for both relays prevented the room ventilation fan from operating during an under-voltage condition, resulting in the Division 1 EOG being inoperable from May 18, 2016 to March 11, 2017, a period greater than allowed by the limiting condition for operation completion time provided in TS 3.8.1. During this inspection, Exelon Generation Company, LLC (EGC) provided the inspectors with a copy of EC 619834, "Evaluate Survivability of Equipment in the Division 1 Diesel Generator Room Due to Failure of EOG Ventilation Fan 1VD01 CA." The purpose of this evaluation was to demonstrate that the Clinton Power Station (CPS) Division 1 EOG would operate successfully during the 24-hour PRA mission time, as described in the NRC Risk Assessment of Operational Events Handbook (RASP), without the fan operating. The inspectors reviewed EC 619834 and concluded that EGC had not provided a reasonable basis to show the EOG would have been able to perform its function for the PRA mission time. Specifically, panel internal temperature would have reached approximately 240°F, a point where some of the key components would have been susceptible to failure. EGC subsequently reviewed the NRC's Inspection Report and performed additional analysis and is providing clarification and additional information associated with the facts and assumptions used to assess the significance of the finding. This additional information provides the basis for EGC's position that this finding is consistent with a finding of very low safety significance (i.e., Green). 2.0 EGC'S POSITION ON NRC INSPECTION REPORT CONCLUSIONS The NRC Inspection Report provides two statements associated with EC 619834 for which EGC is providing clarification and additional analysis to demonstrate that the Division 1 EOG would have performed its safety function during the 24-hour PRA mission time without the EDG room ventilation fan running. The two statements are: Page 1of4

Attachment Exelon Generation Company's Position Concerning the Significance of Apparent Violation EA-17-098 "The [NRG] inspectors reviewed Evaluation 619834 and concluded that the licensee had not provided a reasonable basis to show the EOG would have been able to perform its function for the PRA mission time. Specifically, panel internal temperature would have reached approximately 240°F, a point where some of the key components would have been susceptible to failure. Based upon this conclusion, the inspectors continued with the significance determination."

           "The potential to recover room cooling by opening doors to the diesel generator rooms was added to the base model. NRG staff reviewed the licensee's technical analysis [EC 619834] which included room heat-up calculations and component testing and concluded that if operators opened doors to the room within 30 minutes after diesel generator start and ventilation fan failure there was adequate justification to conc.lude the diesel generator mission would be met."

The additional analysis performed refined the GOTHIC model to increase the accuracy of the analysis and reclassified some components as not needed for the EOG to continue to function (i.e., Critical). EGC's position is that the additional analysis provides reasonable assurance the EOG would have continued to operate for the 24-hour PRA mission time without ventilation fan operation and without opening the rollup door and the personnel door. Note that the limiting component's temperature margin for the case where the operators opened the doors within 30 minutes under EC 619834 is 35°F. The limiting component's temperature margin obtained in the additional analysis (without doors open), EC 620632, is 37°F. 3.0 COMPARISON OF EC 619834 TO EC 620632 LIMITING TEMPERATURE MARGINS EC 619834 provided the bases for the NRC's determination that key components would have been susceptible to failure. In the NRC Inspection Report, it states that panel internal temperature could reach 240°F, a point where some of the key components would have been susceptible to failure. EGC reviewed EC 619834 and determined that the panel where this temperature could be reached is panel 1DG01 JA with a resulting internal temperature of 244 °F. Table 4.3.1, "Critical Devices," of EC 619834 provided the listing of the critical devices (category 1, 2 and 4) that were evaluated along with a summary of the basis for EOG continued functionality under the bounding scenario. In panel 1DG01JA there were two critical devices, both of which were transformers. EC 619834 indicates that these devices will function at a temperature 13°F above the temperature determined in the analysis for that panel (i.e., 13°F margin). However, in EC 619834 the components with the minimum temperature margin of 11°F are located on 1DG01 KA. The re-analysis, provided in the Enclosure (i.e., EC 620632), increases the temperature margin forthe critical components in panel 1DG01JA from 13°F to 41°F. The re-analyzed limiting components continue to be located on 1DG01 KA; their temperature margin was increased from 11°F to 37°F. Page 2of4

Attachment Exelon Generation Company's Position Concerning the Significance of Apparent Violation EA-17-098 Thus, the re-analysis performed in EC 620632 at least triples the temperature margin of the critical components located in 1DG01JA and on 1DG01 KA from that of EC 619834 for the bounding case Loss of Coolant Accident I Loss of Offsite Power (LOCA/LOOP) - Doors Closed case. 4.0 REFINEMENT OF THE GOTHIC ANALYSIS EGG developed an engineering report that evaluates the impact of refining the GOTHIC Model used in EC 619834 to develop a more realistic best-estimate prediction of temperatures within the Division 1 EDG room in order to determine more accurate equipment survivability margin. EGG determined that EC 619834 contained accumulated conservatism in the GOTHIC v. 8.2 model that biased the peak panel temperatures. EGG then re-evaluated the room temperatures by refining the GOTHIC analysis as described below:

1. The revised analysis used the generator heat load consistent with vendor provided information in lieu of 137%.

2. The panels within the room were modeled as enclosures (i.e., control volumes with thermal conductors and flow paths) to determine internal temperatures in lieu of using the maximum temperature the panel experiences on the hottest portion (e.g., the top).

3. Credit for air gaps (e.g., gaps around doors, penetrations to the outside, and other penetrations) to the outdoors were modelled.

4. The engine combustion air inlet piping was credited as a heat sink.

5. The GOTHIC model was re-benchmarked to align to the test data more closely.

6. Outdoor air was modeled using a diurnal cycle and using a more representative peak daytime temperature during the exposure period.

7. For the air flow split associated with the tank room exhaust fan (1VD02CA), a more realistic air flow split was utilized.

When the model was refined and two of the limiting critical component's temperature limits were reevaluated, the resulting minimum component survivability temperature margin is 37°F. 5.0 EQUIPMENT SURVIVABILITY LIMITS REVIEW The Equipment Survivability List provided in EC 619834 identified equipment that is critical for the proper functioning of the Division I EOG during its 24-hour PRA mission time. Under EC 620632 the critical component's survivability temperature limits were reevaluated. As identified on EC 620632 Table, "Margin to Survivability of Critical Components," the generator (G-1 ), exciter (G-2), and engine mounted governors (A9/A9a) survivability temperature limits were increased. The generator and exciter are the most limiting components for exposed elevated temperatures. The increase in their survivability temperature limits aided in the increased margin of 37°F. Page 3of4

Attachment Exelon Generation Company's Position Concerning the Significance of Apparent Violation EA-17-098 6.0 ADDITIONAL RISK INSIGHTS As discussed in EC 620632, temperatures above -175°F are not reached in the LOCA/LOOP-Doors Closed scenario until almost 20 hours into the event. During the LOOP-Doors Closed scenario, room temperatures remain less than 175°F during the 24-hour mission time. This provides additional time for:

1. Restoring functionality to the ventilation fan (and thus restoring cooling to the EOG room). This is very likely, given that highly skilled personnel will be onsite, a simple drawing review would identify the problem, given the chattering relay, and that restoration requires no more than the removal of control power fuses and manual fan breaker closure.

2. Opening area doors or providing alternate cooling (fans located in doorways, etc.).

This "defense in depth" situation provides multiple opportunities for success and provides additional confidence that the EOG would have operated for the PRA mission time.

7.0 CONCLUSION

S: The analysis (EC 620632) evaluated the impact of refining the GOTHIC model for the purpose of generating a more realistic best-estimate prediction of temperatures within the Division 1 EOG room in order to determine equipment survivability margin. The refined analysis resulted in reduced room temperatures and along with increased equipment survivability limits resulted in an increased survivability margin for the limiting critical device(s) for the LOCA/LOOP - Doors Closed case from ~ 11°F to ~ 37°F. As described in the Enclosure, the GOTHIC analysis is still judged to be biased slightly in the conservative direction and the uncertainty in the analysis is judged to be less than 5°F. This uncertainty is small relative to the bounding margin to the survivability limits of 37°F noted above. EC 620632 demonstrates that there is reasonable assurance that sufficient margin exists between the environmental temperatures and the equipment survivability limits for the critical components associated with maintaining the EOG functional for the PRA mission time. As a result, using NRC's IMC 0609, Appendix A, Exhibit 2, this issue should be characterized as Green. Therefore, after consideration of this new information, the appropriate classification for the AV should be changed from White to Green. Page 4 of 4

This EC refines the GOTHIC model developed in NAl-2007-003, R/2 and removes some of the conservatism that was biasing the peak panel temperatures more than required for reasonable assurance. The initial evaluation done in EC 619834 showed 0::11°F margin for the doors closed bounding case 10. The NRC in Ref. 27, enclosure page 7, did not accept the EC 619834 doors closed cases as not providing sufficient margin to provide reasonable basis for DG function during the 24 hour mission time. This EC 620632 subsequently increases the survivability margin and provides additional facts and assumptions in support of a response to the Preliminary White finding to establish reasonable assurance of EOG operation without operator action (i.e. doors closed) for the 24 hour mission time. This EC subsequently supersedes EC 619834. This EC also provides information which may be used as input into PRA analysis to

• assess the severity of the NRC findings, as applicable.

2.0 BACKGROUND

The following event is documented in IR 3982792 and the associated Root Cause Analysis. On 3/7/17 during Operator Rounds, the 'C' Area Operator heard a clicking sound coming from Unit Substation 1A (1AP11 E). The sound was coming from relay 427X2-41A, which was cycling every 10 seconds, which is also the design value for the delay timer associated with the relay. 427X2-41 A (X2 relay) is an Agastat Time Delay Relay (TOR) that provides the signal to reset the Load Shed and Resequencing Circuit for Diesel Generator Room Vent fan 1VD01 CA. Troubleshooting determined that the 1VD01 CA fan was unable to respond to a demand signal following an actual under voltage condition, resulting in Division 1 Diesel Generator being declared inoperable on 03/09/2017. The cycling of the X2 relay was caused by an interaction between the X2 relay and relay 427X3-41A (X3 relay). The X3 relay had been replaced with a different model relay in 2008 due to an obsolescence issue. Replacement on 03/11/2017 of the X3 relay with a Gould J13 relay (original design) allowed the circuit to be restored to operable and exit the Emergency Diesel Generator (EOG) 14 day LCO Action Statement. The station is taking actions to

1. Determine the maximum expected temperatures for the room under LOOP/LOCA and LOOP scenarios with a loss of the room cooling function (this EC 620632)

2. Evaluating equipment in the room to confirm it would not result in an inadvertent shutdown of the EOG within 24 hours (this EC 620632)

3. Evaluate potential recovery actions.

The root cause analysis determined that the X2 (Agastat) relay, which would cause a failure of the 1VD01 CA fan to start during a loss of offsite power (LOOP), was replaced in May 2016. The impacts of variations in the drop-out voltage of the relays used in this circuit were not previously recognized. The reduction in drop out voltage operating margin remained undetected until occurrence of the subject event. The time duration the Division 1 EOG was inoperable was -10 months (between May 2016 and March 2017).

Clinton Power Station EC 620632 RIO EVAL DETAILS Page2 of20 However, the X2 relay did not affect the function of the DG Oil Tank room fan 1VD02CA that would continue to run during a LOOP. This fan pulls in cooling air from the outside through various paths and provides some cooling to the DG room. 3.0 EVALUATION SCOPE The scope of the technical evaluation is to determine the peak temperature of the Division 1 EOG room after loss of room cooling fan 1VD01 CA for 24 hours. This mission time is required by the NRC Risk Assessment of Operational Events Manual (RASP) [Ref. 14]. The equipment in the Div. 1 DG room is evaluated at the elevated temperature to determine if they will impact continued operation of the EOG following a loss of the Division 1 EOG room cooling. This evaluation was performed by

• Using the GOTHIC Model, to determine ambient heat-up temperature
• Determining equipment survivability by performing individual equipment heat-up evaluations and/or testing
• Determining operations response to the EOG vent fan failure by performing table top exercises and a simulator scenario.

Each of these items is evaluated in the following sections: 4.1 Evaluate the DG room temperature through EOG room heat-up evaluations (GOTHIC) 4.2 Determine survivability for equipment essential for DG function by performing individual equipment heat-up evaluations or actual testing and comparing the results to the area temperatures calculated above. 4.3 Determine Operations response to the EOG vent fan failure 4.0 DETAILED EVALUATION: 4.1 Evaluate the EOG functionality through DG room heat-up evaluations (GOTHIC) As discussed in section 2.0, the subject condition would prevent normal operation of the EOG room supply fan 1VD01 CA. The Division 1 EOG Room supply ventilation fan 1VD01 CA would not auto or manually start to provide ventilation to the EOG Room during an auto-start of the EOG following a LOOP scenario [Ref. 2]. Other equipment, including the DG Oil Tank room fan 1VD02CA, was not directly affected by the issue and therefore will operate normally [Ref. 5.c]. A heat-up evaluation of the EOG room was performed, using GOTHIC computer code, to develop temperature profiles of the room during the 24 hour PRA mission time to establish baseline temperatures to determine the survivability of the equipment in the room. The GOTHIC code is general purpose software for transient thermal hydraulic analysis. The GOTHIC model that was developed was benchmarked to actual test data from a recent EOG run. GOTHIC has been used in the nuclear industry for the following items, among others [Ref. 6]:

• Peak Pressure and temperature response during design basis accidents
• ECCS gas bubble accumulation and migration
• Equipment environmental qualification
• HVAC system performance
• Control room habitability due to heat loads or dispersion of toxic/radioactive gases
• Room heat-up analysis

Clinton Power Station EC 620632 RIO EVAL DETAILS Page3 of20 The following critical parameters that affect EDG Room temperature without the normal 77 ,000 CFM Diesel Room Ventilation (VD) air flow were modeled in the analysis:

1. Hot Metal surfaces, e.g. engine exhaust manifold, engine turbo

2. Warm Metal surfaces, e.g. engine block, cooling pipes

3. Generator air cooling (i.e. heat load to the room) fan flow rates

4. Lighting

5. Engine exhaust pipe

6. Overall room air volume and temperature initial conditions, outside air temperature.

7. Wall, Ceiling, Floor areas and materials to absorb heat

8. Diesel oil tank room exhaust fan flow rate and distribution (i.e. dampers and duct configuration)

9. Personnel door and rollup door size and location to evaluate natural circulation (for door open cases)

10. Control building temperature initial conditions through doors to hallway Locations of interest in the EDG Room that are affected by temperatures calculated in the GOTHIC model are:

Panels:

• 1PL12JA
• 1PL92JA/1PL93JA
• 1DG01JA
• 1DG06SA
• 1DG01KA 12cyl
• 1DG01 KA 16cyl
• Area: Near doors when opened On April 27, 2017, test data was taken during the normal DG monthly surveillance at full load [Ref 1O]:

Outside air temperature, room initial temperature, Inlet and outlet temperatures for the room, Inside room local air temperatures at 4 places, at shoulder height

1. Near the roll up door (near panel 1PL12JA),

Thermography:

       - Warm Metal surfaces, e.g. engine block, cooling pipes at approximately 160°F average [Ref. 23]

The initial model was developed by MPR based on design drawings and field walk-downs as documented in MPR calculation 0065-0061-CALC-001 [Ref. 7]. The model was refined in calculation NAl-2007-003 [Ref. 3]. The model was further refined in calculation NAl-2007-004 [Ref. 21]. Adjustments were made to the GOTHIC model to facilitate benchmarking to the test results as follows.

       -    Total heat load was adjusted to match the exit air temperatures from the EDG room
       -    There are variations on hot metal temperatures and warm metal temperatures from the thermography. The GOTHIC model split these into 2 groups, with representative surface areas [Ref.

23], and solved for an appropriate local heat transfer coefficient that preserves total heat load and local temperature distributions.

        -   Generator metal was taking longer to heat up than engine block and engine exhaust manifold &

turbo. Therefore, a slower ramp of heat addition was applied to the remaining heat load representing the generator.

        -   In the NAI model the surface temperature for the warm engine area was conservatively increased from a weighted average of 167°F [Ref. 23] to 172°F and the surface temperature for the hot engine area was conservatively increased from an average of -600°F [Ref. 23] to 700°F (which bound thermography uncertainties per Reference 23).
        -   The NAI model also included more refined sub-division of the Division 1 EOG room.
        -   Refer to Reference 3 and 21 for discussion of additional enhancements of the model.

Several different EOG operating scenarios with doors closed and doors open (roll-up and entrance doors) were evaluated in Reference 3. Based on Reference 3 the bounding cases that constitute the limiting room heat-up for the Division 1 Diesel Generator room following a loss of ventilation include: Case Operating Scenario Door Position 10 LO CA/LOOP Closed 12 LOOP only Closed 7 LO CA/LOOP Open The analysis in Reference 3 contained several conservatisms that were biasing the peak panel temperatures higher than required for reasonable assurances, some of which were subsequently removed in Reference 21, such as:

1. Approximately 137% of the theoretical generator heat load was used in the analysis.

2. Average panel temperatures or internal panel temperatures were not credited. The maximum temperature the panel experiences on the hottest portion (e.g. the top) is applied to component testing limits

3. No credit for air gaps in the room allowing hot air to escape, e.g., gaps around doors, penetrations to the outside, and other penetrations.

4. Some cool surfaces not credited: DG combustion air inlet pipe

5. Conservative application of benchmark penalty of 7°F

6. Design basis 96°F hot summer day outside air and no credit for 24 hour temperature swings to

                -17°F [Ref. 25] cooler at night

7. Diesel Oil Tank ventilation fan flow of 3,020 CFM was conservatively split at 50% from the EOG room and 50% from outside (calculated flow from the EOG room was much greater than 50%).

To refine the EOG room temperature, the GOTHIC model was refined by removing the conservatisms listed above [Ref. 21]. The resulting model was benchmarked to the test data and the GOTHIC model conservatively (i.e. higher) calculated the room area temperatures by 1.6°F to 7.4°F as follows: Measured GOTHIC Calculated Temperature Location Description Temperature Temperature Difference

Clinton Power Station EC 620632 RIO EVAL DETAILS Page 5 of20 indicating that the analysis was biased in the conservative direction . The heat load from the GOTHIC benchmark model was higher (conservative) than the test results [Ref. 21] . The exhaust and inlet temperatures were in close agreement with the GOTHIC Benchmark as shown in Figure 2 from Reference 21 .

The refined model was used to re-analyze the cases from the original analysis as Cases ?a, 10a, and 12a. Temperature profiles are provided for each panel area located in the room for the cases in Attachment 2. A summary of the results are provided below from Reference 21, Table 5-3 for area temperatures and Table 5-4 for internal panel temperatures from the GOTHIC Analysis. I J

• Case ?a is 31°F lower than Case 7
• Case 1Oa is 28°F lower than Case 10
• Case 12a is 43°F lower than Case 12 It should be noted that the original [Ref. 3] Case 7, 10, and 12 models did not model a separate control volume for the panels . The comparison provided is between the control volumes developed in Reference 21 and the hottest cell temperature reported in Reference 3 based on cell temperatures. Compared to the results of Reference 3, the maximum temperature of the hottest panel for each case based on internal panel temperatures compares as follows:
• Case ?a is 39°F lower than Case 7
• Case 1Oa is 37°F lower than Case 10
• Case 12a is 49°F lower than Case 12

Clinton Power Station EC 620632 RIO EVAL DETAILS Page 7 of20 Of particular significance is the fact that all the original Case 7, 10, and 12 simulations predict closure of the fire dampers (at a set-point of 165°F) associated with the modeled ductwork early in the simulation . Cases 7a and 12a do not predict closure of the fire dampers and Case 1Oa predicts closure of the fi re dampers in the last 4 hours of the simulation (Case 10 shows closure in the first 4 to 8 hours). As long as the dampers are open circulation through the DG Oil Tank room via fan 1VD02CA will provide benefit to the Division 1 diesel generator room. The dampers stay open for a much longer period of time as compared to the original cases in EC619834. Attachment 2 shows the resulting temperature profiles. Uncertainties in the GOTHIC Analysis: Although the new analysis removed some of the conservatisms noted above the model is still judged to be conservative. For example, the uncertainties associated with thermography of +/-3.6°F, or +/-2% [Ref. 23 & 24], would result in an uncertainty of-4°F for the engine warm areas and -14°F for the hot areas of the engine. These were accounted for in the analysis by increasing the engine area temperatures by -5°F for the warm area and -100°F for the hot area as follows:

1. Uncertainties associated with thermography potentially under predicting the hot and warm engine temperatures were eliminated by:

a. Increasing the hot engine temperatures by -100°F from the average temperature of 600°F determined during the test (to 700°F).

b. Increasing the warm engine temperatures by -5°F from the average temperature of 167°F determined during the test (to 172°F).

c. These two increases resulted in an associated bias of -4°F conservative based on the sensitivity analysis performed in NAl-2007-004, Attachment C, page C12 , Case 10b [Ref.

21]. The model was benchmarked to the test data and the GOTHIC model calculated the area temperatures conservatively by 1.6°F to 7.4 °F. The margin between the GOTHIC model and the test data exceeds the instrument uncertainty of approximately 0.54°F [Ref. 23 & 24] for the fluke thermometers that were used to measure the area temperature, showing that the analysis was biased in the conservative direction. As part of the analysis, a sensitivity run was also performed assuming an increase in delta T of 0.8°F [Ref. 23], which covers the SRSS of the instrument uncertainty of the fluke thermometers used to measure air temperatures of the EOG room supply and return air. The resulting area and internal panel temperatures, for the bounding LOCA/LOOP case, increased by 3°F to 5°F, respectively, based in NAl-2007-004, Attachment C, Page C12, Case 10c [Ref. 21]. The physics for this scenario predominantly involve heating of air in a large room and heat transfer from the engine and generator. The majority of the heat is from the generator which is an accurate value at a given load . The other major heat load is from the engine and was validated during benchmarking . The analysis methods used by GOTHIC for this type of scenario are based on well understood and accepted concepts and equations. It is not affected by more complicated mechanisms such as those that predominate in a containment LOCA analysis. The analysis for this type of scenario would subsequently be very accurate. A measure of the uncertainty or bias can be determined by looking at the conservatisms in the model and the results as reflected by the benchmarking . Even though several conservatisms were removed in the updated analysis, conservatisms such as the use of elevated temperatures for the warm and hot area temperatures remained . Also , the hottest day night temperatures of the entire 10 month relay failure period was conservatively used . Another indication of the conservatisms in the model can be seen Reference 21, Table 5-2 where the vendor supplied engine heat load at design area temperatures (122°F) was compared to the benchmark based value (i.e. for engine =6.15 Btu/hr-ft2). The GOTHIC based heat load at 122°F was 19% conservative [Ref.21] relative to the vendor supplied value. The resulting model was subsequently benchmarked to the test data and as one might anticipate the GOTHIC model over-pred icted the area temperatures by 1.6°F to 7.4°F. As such the analysis was judged to still be sufficiently conservative such that additional uncertainties need not be applied to the analysis approach.

Clinton Power Station EC 620632 RIO EVAL DETAILS Page 8 of 20 The overall uncertainty based in instrument accuracy investigated in NAl-2007-004, Attachment C, Case 10c [Ref. 21] as discussed above, is therefore expected to be less than approximately 5°F which is small fraction relative to the margin to the survivability limits as discussed in the sections that follow. 4.2 Determine equipment survivability by performing individual equipment heat-up evaluations or actual testing Electrical Equipment: The equipment that is most susceptible to failures that could cease DG function under elevated operating temperatures is electrical equipment. Elevated temperatures can impact the functionality of equipment in several ways . Over time, elevated temperatures can increase the degradation of organic materials in electrical devices. Elevated temperatures can also prevent voltage sensitive devices (e.g., electrical devices with coils) from picking up at desired voltages as it is an established phenomenon of most electrical circuits that the resistance of a current path will rise as temperature is increased, resulting in an increase in the pick-up voltage (and subsequently earlier drop-out) of devices with coils. To determine the scope of electrical equipment that needed to be evaluated, a review of the electrical design drawings [Ref. 5, E02s and E03s] was performed and approximately 250 devices were identified that were associated with the EOG room and required additional evaluation. The detailed evaluation of this equipment is included in Attachment 1 of this EC. The detailed evaluation considered the function and the failures modes of the devices to determine those devices that could prevent the EOG from performing its required function during the 24 hour mission time. For critical equipment the threshold temperatures for survivability was determined based on evaluation or testing . The panel temperature rise (e.g. 23°F for panel 1PL12JA) was also considered . The following provides a summary of how critical equipment was identified . Refer to Attachment 1 for additional details. The Equipment Survivability List identified equipment that is critical for the proper functioning of the Division I Emergency Diesel Generator. The "Critical" components were defined as devices whose failure due to exposure to elevated temperature could prevent the EOG from performing its function by, for example, direct tripping the EOG or causing an associated device to trip the EOG. These components are further divided into those components classified as "critical active" and "critical passive". The critical active components are capable of direct tripping or causing a trip of the EOG. The critical passive components are capable of indirect tripping of the EOG due to a passive failure (e .g. loss of continuity) . The Equipment Survivability List was divided into five categories based on function and criticality of the components, and their ability to impact continued operation of the EOG as follows :

1. "Yellow"; this group of components contains devices that can potentially trip the EOG and are not blocked by the presence of a "LOCA bypass signal". The "LOCA bypass signal" is generated when conditions indicative of a LOCA are detected or when manually activated by operators. This list includes instruments and supporting devices designed for protection of the EOG. There are a total of 35 components in this group with 5 considered "critical active" and zero "critical passive".

2. "Pink"; this group of components contains devices that can potentially trip the EOG but are blocked by the presence of a "LOCA bypass signal". This list includes instruments and supporting devices designed for protection of the EOG . There are a total of 21 components in this group with 5 considered "critical active" and zero "critical passive".

3. "Green"; this group of components contains devices required for starting the EOG. After the EOG starts, these devices cannot provide any tripping function and will not be considered as being affected by the effect of high temperature. There are a total of 42 components with no "critical active" or "critical passive" function .

4. "Blue"; this group of components contains devices that are required for power delivery or regulation .

None of these components can directly trip the EOG but, however, can cause a trip by one of the protecting devices. There are a total of 38 components with 11 considered "critical active" and 10 "critical passive".

Clinton Power Station EC 620632 RIO EVAL DETAILS Page 9 of20

5. "White"; this group of components contains devices that have no direct impact to the EOG operation. There are a total of 123 components in this group with no "critical active" or "critical passive" function.

In summary, 21 components have been classified as "critical active". Ten of these devices were functionally tested at elevated temperatures, in direct support of this evaluation . Ten components were classified as "critical passive" . Each of these 31 components where evaluated considering their failure modes and effects. For example:

• Failure Mode: A typical electro-mechanical relay failure mechanism due to elevated temperature is a "failure to energize".
• Effect: A normally de-energized relay will not cause an EOG trip because the relay is already in the failed state .

A description of the device function and potential impact caused by their failure mechanism is described in the table below. Note that Agastat relays had been previously identified as having "low margin 1" to survivability limits because, although one had passed testing at 238°F, another Agastat relay had failed at 245°F. Per Failure Modes and Effects Analysis in Supplement A, it has been determined that these relays are no longer classified as critical and have no impact on EOG operation under the subject scenario . As a result, these components were removed from the Critical Components List. The following table summarizes the results for the 21 components that have been classified as "critical active" based on the evaluations in Attachment 1. Attachment 1, Table V-2 provides the evaluations for the 10 "Critical Passive" components. See Attachment 1 for additional details on the methodology, design inputs, additional references and component testing temperature vs time profiles used to perform the evaluations.

The relay was tested at 225 °F for 24 hours followed with an exposure to 245°F for 8 hours. The relay did not provide a false trip. Therefore, the relay will not impact the normal operation of the EDG at 245°F. Accounting for a 23°F panel temperature rise, the relay will not impact the EDG normal operation in a room ambient temperature of 222°F . 1PL12JA-A4 Wood- 2301A Governor Control Assembly - This device controls the EDG speed, ward receiving feedback from the magnetic pickup speed sensor (AS) and inputs from the speed adjustor (Rl l). The governor control assembly was tested at 207°F for 24 hours, 225 °F for 8 hours and 245 °F for 8 hours. The output of governor control did not drift from the operating condition (remained at 0 YDC for 60HZ operation). Therefore, the governor control will maintain the normal operation of the EDG at 245°F. Accounting for a 23 °F panel temperature rise, the governor control assembly will not impact the EDG normal operation in a room ambient temperature of 222°F . 1DG01KA-A9/A9a Wood- EGB-13P Actuator Governor (Mounted on Engine) - The function of the governor 1 The associated equipment ambient temperature limit (Tiim;i) would be 238°F minus the 23°F measured panel (1PL12JA) temperature rise or 215°F. In the initial evaluation done in EC 619834 the room ambient temperature near the subject panel was 204°F resulting in 11°F margin.

Clinton Power Station EC 620632 RIO EVAL DETAILS Page 10 of20 COMPONENT MFG PART NO. EVALUATION ward is to modulate and control engine fuel flow in accordance with system load. The Governor is located on the cool side of the engine (i.e. opposite the turbo chargers) between the engine and the jacket water cooler. It will therefor tend to be in a cooler area. Based on VTIP K2861-0002-B, R/87 (Woodward EBG- Proportional Governor Actuator, #82340C), the Governor is used on both steam and engine prime movers. Based on VTIP K2861-0002-B (page 9), the recommended operating range of the unit is up to 250°F with synthetic oil . Significant aging of the oil in the Governor would not occur for minor excursions in temperature for a short duration in time. The Governor, once the engine was up and running at steady state (which occurs early in the event), is not heavily loaded (i.e. it does not need to move much) and therefor would not develop significant heat in the oil. Based on NSED Standard MS-01.00, R/46 (Equipment Lubrication Standard), the device is to be lubricated with MOBIL 1 SW-30. MOBIL 1 SW-30 is synthetic oil that has better performance in high heat applications than conventional motor oils (Attachment 0). Therefore, the governor would be expected to operate for short periods of time (less than 6 hours) at the end of the scenario at elevated ambient temperatures (-250°F) with MOBIL 15W-30 lubricant. IDGOlJA-CTl -6 GE,JCS- JCS-0/687X6 Current Transformers (CT) - These current transformers provide current 0 signal to various protecting devices such as the Current Differential Relay, Overcurrent Relay, Reverse Power Relay, Loss of Field Exciter, and Governor. CT's are robust devices that have no electronic components. Under the scenario by the time the room sees significant heating the EDG will be functioning properly at a steady state and significant challenge would not be expected . The CT insulation was aged at 257°F. The function of the devices depends on the integrity of the insulation system. The CT insulation was aged at 257 °F and functionally tested before and after aging. Accounting a panel temperature rise of 23°F, the component will function at 234°F room ambient temperature. 1PL12JA-32 GE 12GGP53BlA Reverse Power Relay - The function of this device is to shut down the EDG upon detection of reverse power to prevent motorizing the generator. The relay was tested at 225°F for 24 hours and 245°F for 8 hours. The relay did not provide a false trip. Therefore, the relay will not impact the normal operation of the EDG at 245 °F. Accounting for a 23 °F Panel temperature rise for panel 1PL12JA, the relay will not impact the EDG normal operation in a room ambient temperature of 222°F. 1PL12JA-40 GE 12CEH51AlA Loss of Excitation Relay - The function of this device is to shut down the EDG upon detection of loss of excitation on the generator. The relay was tested at 225°F for 24 hours followed with an exposure to 245°F for 8 hours. The relay did not provide a false trip. Therefore, the relay will not impact the normal operation of the EDG at 245 °F. Accounting for a 23 °F cubicle temperature rise for panel IPL12JA, the relay will not impact the EDG normal operation in a room ambient temperature of 222 °F. 1PL12JA- 51V-l ,- GE 12IJCV51A12A Voltage Restrained Overcurrent Relays - The function of these devices is 2,-3 to shut down the EDG upon detecting overcurrent condition. The relay was tested at 225°F for 24 hours followed by 245°F for 8 hours. The relay did not provide a false trip. Therefore, the relay will not impact the normal operation of the EDG at 245°F. Accounting for a 23°F

EVALUATION Panel temperature rise, the relay will not impact the EOG normal operation in room ambient temperature of 222°F . 1PL12JA-Al Basler SR8A2B01B3A The device regulates the EOG output voltage and takes input from CTs and PTS and A2 (Series Boost Option) and AlO (Under Frequency and Over Voltage Assembly). The voltage regulator was tested at 225°F for 24 hours followed by 245 °F for 8 hours. The voltage regulator performed its desired function and did not provide any false trip signal to the EOG throughout the 32 hours of test run. Accounting for a 23°F Panel temperature rise, the voltage regulator will not impact the EOG normal operation in a room ambient temperature of 222 °F. 1PL12JA-A2 Basler 90-3 7100-100 Series Boost Option - The function of this device is to boost the exciter voltage to maintain rated voltage during EOG operation. This device has passive components such as resistors, capacitors, transformer and inductive coil. As the components were aged at 257°F for -44 days [Ref. SQ-CL0070] and were functionally tested before and after aging and there are no moving parts and electronics, the device will function for an operating temperature of 257°F. Accounting for cabinet temperature rise of 23°F, this device will be functional at a panel ambient temperature of 234 °F . 1PL12JA-Al0 Basler 9-1051-00-100 The device detects under frequency and over voltage conditions and provides feedback to Al (voltage regulator) regulate the voltage. The UFOV was tested at 225°F for 24 hours followed by 245°F for 8 hours. The UFOV performed its desired function and did not provide any false trip signal to the EOG throughout the 32 hours of test run. Accounting for a 23°F Panel temperature rise, the UFOV will not impact the EOG normal operation in a room ambient temperature of222°F . lDGOlJA-CCT GE JCS-0/687X6 The current transformer provides line current input to the Al voltage regulator. CT's are robust devices that have no electronic components. Under the scenario by the time the room sees significant heating the EOG will be functioning properly at a steady state and significant challenge would not be expected. The function of the devices depends on the integrity of the insulation system. The CT insulation was aged at 257°F for -93 days [Ref. SQ-CL0046J and functionally tested before and after aging. Accounting a panel temperature rise of23°F, the component will function at a room ambient temperature of234°F . lDGOIJA-CTI0-11 Basler BE-02463-001 The current transformers provide line current input to the series boost option (A2). CT' s are robust devices that have no electronic components. The CT insulation was aged at 257°F for -82 days [Ref. SQ-CL0055]. The function of the devices depends on the integrity of the insulation system. Accounting a panel temperature rise of23°F, the component will function at a room ambient temperature of234°F . 1DG01KA-Gl/G2 IDEAL Generator and The Generator provides 3875KW at 4160 volts. The limiting material in Exciter the generator is judged to be the insulation. The Insulation is rated for 155°C (Class F). The minimum thermal life of Class F insulation is more than 1000 hours at 200°C operating temperature (NUMARC 87-00, Rv. 01). The temperature rise at full load is 70°C (See Section 5.12 of Ref. Vill.2). Based on TODI-CPS-17-025, the peak load on the EOG during the LOCA/LOOP case is 3721.2 KW and the peak load for the LOOP case is 3334.8 KW. The EOG is rated for 3900 KW continuous rating (OWG E02-1AP12, Sheet 031, Rev. J), the corresponding load for the LOCA/LOOP and the LOOP is 95.4% and 85.5% respectively. Therefore, the generator temperature rise at 95.4% rated load is 63.7°C

             *== =--*~

[70*0.954*0.954 = 63 .7°C] . Assuming the same temperature rise, the

Clinton Power Station EC 620632 RIO EVAL DETAILS Page 12 of20 COMPONENT MFG PART NO. EVALUATION generator will be exposed to 173.7°C when operating in an ambient temperature of230°F (110°C) [i.e., ll0°C + 63.7°C = 173 .7°C) . The generator temperature will be 18.7°C above its long term rating of 155°C. However, the generator is rated for 20,000 hours of operation at 155°C and this life will be reduced by a factor of 3.66 using the 10°C rule for a long term life of more than 227 days. Therefore for a short term operation of 1 day, the impact on the generator thermal capability when operating at 230°F is negligible. The minimum thermal life of 1000 hours at 200°C from the NUMARC 87-00 report also exceeds the EDG thermal stress for 1 day by a large margin. Rotating Brushless Exciter - The function of the brushless exciter is to maintain a nearly constant voltage of 4160 volt out of the generator through elimination of brushes, collector rings and carbon dust. The insulation degradation due to high temperature has been evaluated to be the limiting parameter of interest. Insulation is rated for 155°C (Class F). The minimum thermal life of Class F insulation is more than 1000 hours at 200°C operating temperature (NUMARC 87-00, Rv. 01 ). The temperature rise of the exciter is 80°C (See Section 5.11 of Ref. Vill.2). The insulation life is 20000 hours at 155°C. For an operating environment of230°F (110°C), the exciter temperature will reach 190°C. The life at this temperature is 1767 hours (73 days) using 10°C rule. Therefore for a short-term operation of I day, the impact on the exciter thermal capability when operating at 230°F is negligible. The minimum thermal life of 1000 hours at 200°C from the NUMARC 87-00 report also exceeds the Exciter thermal stress for I day by a large margin. (See Attachment I , KCI Evaluation Report) . 1PL12JA-Kl5 P&B MDR137-8 The relay protects the CCT on loss of power by shorting the CCT terminals. The relay shorting also can prevent the CCT output to Al (voltage regulator). The tested relay was aged at 225 °F energized at 125 VDC for 24 hours followed by 245°F while energized at 125 VDC for 8 hours. The coil maintained the circuit integrity and open contacts did not short circuit throughout the 32 hours of test run. Accounting for a 23 °F panel temperature rise, the relay will not impact the EDG normal operation in a room ambient temperature of222°F. lDGOlJA-PTl, PT2 GE JVM-3/643X92 The potential transformers provide input to the voltage regulator (Al). PT' s are robust devices that have no electronic components. Under the scenario by the time the room sees significant heating the EDG will be functioning properly at a steady state and significant challenge would not be expected. The function of the devices depends on the integrity of the insulation system. The PT insulation was aged at 257°F for 87 days [Ref. SQ-CLD016] and functionally tested before and after aging. Accounting a panel temperature rise of 23 °F, the component will function at a room ambient temperature of234°F. lDGOUA-Tl Basler BE-13487-001 Voltage Regulator Power Transformer - This transformer provide voltage information signal to the UFOV assembly (AlO). Voltage transformers are robust devices that have no electronic components Under the scenario by the time the room sees significant heating the EDG will be functioning properly at a steady state and significant challenge would not be expected. The function of the devices depends on the integrity of the insulation system. The insulation was aged at 257°F for -82 days [Ref. SQ-CLD079] and functionally tested before and after aging. Accounting a panel temperature rise of23°F, the component will function at a room ambient temperature of 234°F . Additional details are provided in the EOG Survivability tables in Attachment 1.

Clinton Power Station EC 620632 RIO EVAL DETAILS Page 13 of 20 4.3 Determine Operations response to the EOG vent fan failure The failu re of the Division 1 VD fan to start was presented to Operations crews once in the simulator and table-topped twice. The simulator performance had members of multiple crews due to Operations staffing being re-aligned for the upcoming refueling outage. All 3 times, the decision was made to open the roll up door and personnel door to the hallway for Division 1 EOG room . The Shift Operations Superintendent (SOS) questioned some of the crew members separately and got responses from individuals that they would have, individually, come to the same conclusion. There were discussions concerning the opening of doors that would create divisional separation issues, but no opposition to opening the two doors of interest. The Shift Operations Superintendent, therefore, has a very high degree of confidence based on his discussions with the crews that any crew would come to the same conclusion to open the doors. Some of the crews addressed opening additional doors but not all of the crews were willing to, so he was not comfortable assuming that additional doors would be opened . The scenario is:

• The plant is at power.
• Off-site power is lost.
• Div. 3 starts and is available for loading
• Div. 1 DG starts but the vent fan does not
• Div. 2 DG does not start Operators were united in leaving Division 1 DG running and opening the personnel door and rollup door to the hallway to get whatever cooling it would provide while pursuing restoration of the Division 2 DG . If Division 2 were operating , Division 1 would likely be shut down as the room heats up.

In order to establish a reasonable time to complete these actyions, a timed walkdown was performed . A qualified Equipment Operator/Safe Shutdown Qualified (SSQ) Operator performed the evolution of opening the roll up door and blocking open the personnel door to the hallway. The SSQ had to obtain tools and a blocking device as part of the timed evolution. These items are readily available in the EOG rooms. A previously licensed SRO walked the path that represents the longest time it would take to get from the most remote place that the SSQ could be expected to be (Division 3 SX pump room) to the Division 1 EOG room. Ample cues would be present on a loss of off-site power to cause the SSQ to report to the EDGs as required . The combination of these two evolutions was under 30 minutes. 5.0 RESULTS AND CONCLUSIONS: Results: The engineering report in Attachment 2 provided an accurate prediction of maximum area temperatures for the subject scenario within the Division 1 EOG room in order to determine equipment survivability margin . The refined analysis improved the precision of the model which resulted in increased margin to equipment survivability limits. The margins to survivability of critical components can be determined by comparing the threshold temperatures from table V-1 and V-2 from Attachment 1 to the applicable panel or area temperatures from as shown in the following Table.

== Conclusions:==

1) Margins to the survivability limits for critical devices increased from Ref. 3 to Ref. 21 as follows:

a) The margin for the LOCA/LOOP- Doors Closed (case 1Oa) increased from ;:::11°F to ;:::37°F i) The new margin of 37°F for the bounding door closed case (1 Oa) exceeds the margin of 35°F for the LOCA/LOOP-Door Open case (7) that was determined in the original evaluation [Ref. EC 619834] ii) The worst case margin for critical equipment that is located inside panels (1PL12JA & 1DG01 JA) was 41°F. The worst case margin for critical devices that were recently tested in support of this evaluation was also 41°F iii) Note that the ambient temperatures for the LOCA/LOOP- Doors Closed at the end of approximately 20 hours was similar to the LOOP-Doors Closed at 24 hours. (1) The resulting margins (58°F) shown below for the LOOP Case would therefore be applicable for the LOCA/LOOP case for approximately 20 hours, with significantly elevated temperatures present for only the last 4 hours of the scenario due to closure of the dampers at 165°F. (2) It is expected that the operators will open the roll-up door or the fan will be able to be started, within 20 hours, well before peak temperatures are reached, by performing corrective maintenance {for example by pulling a fuse to the suspect relay) as directed by the ERO. b) The margins to the survivability limits for the LOOP-Doors Closed (case 12a) increased to

                 ;:::sa°F c) Although it is expected that the dedicated SSQ Operator(s) will open the Division 1 EOG room doors when it is recognized that the HVAC has failed or when the area is becoming uncomfortably warm, even if the operators fail to open the roll-up door and personnel access door the Division 1 EOG will meet its mission time.

2) The overall uncertainty in the Ref. 21 analysis is judged to be less than 5°F, based on sensitivity runs performed in NAl-2007-004, Attachment C, which is small relative to the bounding margin to the survivability limits of 37°F noted above.

The results demonstrate that the margin between the expected maximum local area temperatures in the diesel generator room after 24 hours for the subject scenario results in a local temperature much lower than the component survivability limits for critical devices. The margin is sufficient to conclude that the diesel generator will in fact continue to operate successfully for the entire PRA mission time without fan cooling or any operator action. The equipment survivability margin was calculated in a manner that addresses uncertainties, and therefore provides "reasonable assurance" of diesel generator operation for the desired time period. Based upon the survivability analyses provided, it can be concluded that the increased likelihood of diesel generator failure due to room heat-up is in fact virtually zero, even with the doors closed for the entire mission time. The robust nature of the diesel generator and supporting components ensures its operation for the duration of the PRA mission.

Clinton Power Station EC 620632 RIO EVAL DETAILS Page 16 of20 In addition opening the roll up and entrance doors or restoring functionality to the VD Ventilation fan (and thus restoring normal cooling to the diesel generator room) prior to reaching relatively high temperatures (at -20 hours) are both highly likely, given that dedicated operators will be present in the EDG room and additional highly skilled personnel will be onsite to assist with fan recovery. Note that opening of doors is a very simple activity and fan restoration requires no more than the removal of control power fuses, and manual fan breaker closure. These provide additional measures of defense in depth, thereby providing extensive assurance that the diesel generator will operate for the PRA mission time. The combination of analysis and actual station conditions and responses virtually eliminates a risk level above baseline for the condition described and the associated safety significance is therefore very low (i.e. Green).

Clinton Power Station EC 620632 RIO EVAL DETAILS Page 18 of20 Supplement A: Evaluation of Agastat Timing Relays Used In The EOG, Division I. The Agastat timing relays provide time delay for different types of control functions. In the application of the EOG control system, there are various uses of the Agastat timing relays, but none of them can be considered critical for the proper functioning of the EOG. There are three different configurations of Agastat timing relays: One in category 1 (Yellow) One in category 2 (Pink) One in category 4 (Blue) Category 1 AGASTAT TIMING RELAY (K41) provides a 2-second window to open the contact of relay K41X to remove the tripping signal for the over speed trip solenoids (L03 and L03A). The solenoids L03 and L03A trip the mechanical over speed trip mechanism on both engines (12 cyl and 16 cyl). The purpose of the Agastat timing relay is to remove the tripping signal after 2 seconds because the over speed trip mechanism latch up closed and will not require the presence of any signal to remain closed. Should the Agastat fail to energize, the tripping signal will still reach the over speed trip solenoids through the normally close contact of the Agastat relay and carryout the intended function of the over speed actuation switches (S9 and S9A). Note that under the subject scenario the EOG is running correctly and at steady state well before significant room heat-up occurs and therefor an over speed condition is not postulated. Category 2 AGASTAT TIMING RELAY (K5) provides a 50 seconds time delay to allow the various engine systems to stabilize at their normal operating levels. After the 50 seconds time delay lapses, the following protecting devices will be able to trip the engine upon detection of abnormal condition: Low Oil Pressures (S19, S19A), and High Coolant Temperatures (S25, S25A). Should the Agastat timing relay fail after the engine is operating, these four devices will not be able to trip the EOG. However, the failure of the Agastat relay by itself will not trip the EOG. Note that these four devices are among the various instruments that are bypassed by the presence of a LOCA bypass signal. They have also been evaluated for the expected room temperatures during the subject scenario. Category 4 AGASTAT TIMING RELAY (K6) provides a 1.5-second time delay to allow Field Flashing. Field Flashing is required to ensure that sufficient residual magnetism will exist to allow the generator to build up voltage during startup. Relay K6 also allows remote adjustment of engine speed during startup. Since these functions are required only during startup when the EOG room temperature is still low, there will be no impact to the EOG operation under the subject scenario at elevated room temperatures.

Clinton Power Station EC 620632 RIO EVAL DETAILS Page 19 of20 Supplement B: Assessment of Impacts per CC-AA-102, Design Input and Configuration Change Impact Screening. If no impacts exist, state so. The purpose of this evaluation is to provide reasonable assurance of continued EOG operation for the 24 hour mission time following a failure of the Division 1 DG Room Cooling Fan 1VD01CA to start on a LOOP signal. It may also be used to develop inputs for PRA analysis to address the severity of an NRC finding relating to the failure of the Division 1 DG Room Cooling Fan 1VD01 CA to start on a LOOP signal. Therefore there are no configuration changes made as a result of this evaluation. The CC-AA-102 checklist will be used as a guide to determine items that are evaluated for the PRA analysis. 4.1.4.1 - IDENTIFY Basic SSC Functions The design functions of the Division 1 DG Room Cooling System are described in USAR Section 9.4.5.1 and subsequent sub-sections, "Each diesel-generator facility ventilation system is designed to limit the maximum - temperature to 130°F corresponding to a summer design outside temperature of 96°F in the diesel-generator room." 4.1.4.2/4.1.4.3 - IDENTIFY Configuration Change safety classification and Seismic Classification. This evaluation serves to provide reasonable assurance of operation of the EOG for a condition that is no longer in place (i.e. historical). It is subsequently classified as non-safety related and non-seismic. 4.1.5 - PROVIDE the performance requirements and design conditions (including margin) of the SSC needed to evaluate the change from the existing to the modified systems, structures, or components: The 1VD01 CA fan is required to supply cooling flow to the Division 1 DG room to maintain room temperature below 130°F for reliable operation. However, due to the relay failure, the fan was not able to perform this function. This evaluation determines the temperature in the Division 1 DG room with no room cooling and evaluates if the associated equipment in the room can still function for 24 hours following loss of room cooling. 4.1.9 - DETERMINE changes required to existing Design Analysis or new parameters that require new calculations or calculation revisions that are used to assess the acceptability of a system or a component function in meeting various physical requirements. Much of this evaluation is based on calculations from vendors including Zachary Group, MPR Associates and KCI. These inputs are not intended to be design basis analyses, but instead to inform the PRA model. 4.1.11 - IDENTIFY any Failure Effects requirements. The root cause evaluation determined that the failure of the Division 1 DG Room Fan to start was caused by the failure to recognize the variations in the dropout voltage and associated impacts of the relays used in this circuit. 4.1.14 DETERMINE environmental conditions and impacts. The Division 1 DG room temperature due to the failure of the room fan to start is determined via GOTHIC analysis as described in Attachment 2. L

Since the information in this evaluation will be used to address the severity of an NRC finding and may be used as input to risk evaluations, the PRA group will review this evaluation. See 4.1.42 for Interfacing Department reviews. 4.1.19- EVALUATE if System Operational Requirements have changed. System operational requirements have not changed. However, operator actions to mitigate the loss of room cooling event are described in this evaluation. 4.1.33 IDENTIFY Mechanical System Characteristics where design limits are placed on the mechanical properties of a system or component.

Operability of Class 1 E Equipment in DG Rooms as a Result of a Loss of the Diesel Ventilation VD Fan I Purpose The purpose of this report is to perform an operability assessment of Class IE equipment in DG rooms (DIV 1) exposed to higher-than-expected temperatures resulting from a loss of diesel ventilation VD fans. II Summary of the Review As a result of the loss of the diesel ventilation VD fans, all the Class IE equipment required for DG operation and located in the DG rooms will remain operable during the elevated DG room temperatures for a maximum 24-hour period. III Background On Tuesday, March 7, 2017, an Equipment Operator observed a relay cycling every IO seconds from the Division I 480V Unit Substation lA (lAPI IE). This relay is part of a logic circuit in the 480V Unit Sub IA and supports the under-voltage load shed and restoration of the Division 1 Diesel Generator ventilation. The logic would initially shed the DG fan on under-voltage, preclude the fan from restarting, then after IO seconds, once voltage is restored, allow the ventilation to be restored either by the EDG start or return of the safety bus. The ventilation is sequenced on at I 0 seconds after power restoration per the sequential start strategy. The troubleshooting efforts determined the relay 427X3-41A (an interposing relay that acts as a seal-in circuit, in the undervoltage relay logic for IAPl IE) operates outside of allowable circuit parameters, causing the cycling of timing relay 427X2-4IA. Troubleshooting attachments identified both the X2 and X3 relays operated contrary to their expected transient on de-energization resulting in the X2 relay changing contact states before the X3 relay contacts. This condition has two impacts: (I) Associated DG room fan (1 VDOlCA) would be unable to start either automatically or manually when required, and (2) Ability of Division 1 DG to properly load shed on a bus undervoltage condition is affected. As a result, Division 1 DG was declared Inoperable at 03 I9 on March 9, 20I7. Page 5 of83 I

Operability of Class 1 E Equipment in DG Rooms as a Result of a Loss of the Diesel Ventilation VD Fan As part of the investigation, it was determined that the identified relay cycling was initiated. by a bus undervoltage condition. Historical surveillance testing was reviewed. DG integrated surveillance procedure 9080.21, which tested Division 1 ECCS system response to a simulated LOCA I LOOP signal, does test the affected relay logic in a manner to detect this condition. However, the fast performance of 9080.21 was in October 2013. The X2 timer relay was replaced in May 2016. Separate testing of the time delay relay function ONLY was last performed in May 2016, satisfying the 48 month periodicity requirement for the time delay function. However, this testing does not initiate a bus undervoltage condition and would not have been sufficient to detect this condition and fully validate proper function of the affected circuit. In the event of a LOOP, the Division 1 EDG would have started and the Generator's output breaker would have closed providing voltage to the safety related buses. However, the suspect relays would have prevented the VD Vent Fan from running and there would have been no cooling to the EDG Room. Without further evaluation and justification, the EDG would not have been able to meet its mission time. The analysis presented herein is a collaborative effort between Clinton Power Station (CPS) and Kiran Consultants, Incorporated (KCI). IV Evaluation Parameters This analysis evaluates operability of equipment in the DG Room for a duration of 24 hours at maximum temperature values as follows:

• Panel lDGOlJA 225°F
• All Remaining Components in the DG Room 215°F Justification for operation is provided for equipment that cannot meet the above parameters.

Operability of Class 1 E Equipment in DG Rooms as a Result of a Loss of the Diesel Ventilation VD Fan V Operability of Class lE Equipment in DG Rooms as a Result of Loss of Diesel Ventilation VD Fan V.1 General Discussion on the hnpact of Elevated Temperature on Equipment Elevated temperatures can impact the functionality of equipment in several ways. Over time, elevated temperatures can increase the degradation of organic materials. Elevated temperatures can also prevent voltage sensitive devices (e.g., electrical devices with coils) from picking up at desired voltages as it is a well-known phenomenon of electrical circuits that the resistance of a current path will rise as temperature is increased, resulting in an increase in the pick-up voltage of devices with coils. The analysis presented herein will generically address methods for determining the impact of elevated temperatures on organic materials and then specifically address the effects of elevated temperatures on voltage-sensitive devices. This analysis will also specifically address the impact of elevated temperatures on normally open relays. V.1.1 Determining the hnpact of Temperatures on Organic Materials V.1.1.1 Arrhenius Methodology Arrhenius methodology has been shown to be a valid means of modeling temperature effects and for evaluating thermal degradation of non-metallic materials. Note that metallic materials are virtually unaffected by environmental conditions associated with temperatures experienced in nuclear plant environments, therefore, the impact of elevated temperatures on metallic materials is insignificant. The following form of the Arrhenius equation is typically used when relating service temperature and duration to a shorter duration at a higher temperature used for accelerated (thermal) aging of non-metallic materials at actual laboratory test conditions. Equation 1 Where: Page 7 of83 I

V.1.1.2 10°C Rule Another model for assessing the time-temperature effects on non-metallic materials is the 10°C rule. This rule simply states that chemical reaction rates double and the material life decreases by one-half for every 10°C increase in temperature. For example, a material with a thermal life of 20 years at a service temperature of 40°C will have a thermal life of 10 years at a temperature of 50°C. V.1.2 Determining Impact of Elevated Temperatures on Voltage Sensitive Devices The DC relays pickup (change state from de-energized to energized with aux contacts changing state) when the magnetic force generated by the coil current compresses a spring and the plunger travels decreasing the air gap in the iron core to almost zero. The coil current is directly proportional to the voltage across the coil divided by the coil resistance (Ohm's Law). The coil resistance is dependent on the ambient temperature given the by the following equation (Equation 2-9 of Attachment R): 234.4 + t 2 Rt2 = Rt1

• 234.4 +ti Where: Rn= Coil Resistance at Room Temperature of tr Rt2 = Coil Resistance at tz tr= Room Temperature (typically 20°C (68°F))

t2 = Operating Temperature Therefore, using the above equation, the pickup voltage at any temperature t2 can be calculated from the pickup voltage at room temperature tr by using the following equation:* Page 8 of 83 I

V.1.3 Determining Impact of Elevated Temperatures on Normally Open Relay A relay is an electromechanical switch made of 4 basic parts: electromagnet, mechanical switching element (that can be attracted by the electromagnet), spring, and set of electrical contacts. The three principle failure modes of a relay are (1) failure to trip, (2) spurious trip, and (3) short. Relevant mechanisms by which these failure modes can occur are contamination (metallic and non-metallic) and mechanical wear of the internal switching element. ,Relays are less likely to unintentionally close when configured with normally open contacts. Therefore, the task for this configuration is to determine whether or not abnormal elevated temperatures can cause the unwanted closure of the normally open relay. For the subject relay switches, the non-energized state is normally open, meaning that the relay coil is de-energized and the contacts are open, however, due to applied voltage, the relay may experience some amount of leakage current across the contact. As such, the only credible failure mode under abnormal elevated temperatures (that would lead to closure of the contacts or enable the relay to carry sufficient current so as to close the relay circuit) would be degradation of the nonmetallic materials of construction or significant leakage current across the contacts. Each failure mode is discussed separately. The non-metallic materials of construction under consideration are the materials of the contact block. Note that metallic materials (i.e., the spring and contacts in the relay) are virtually unaffected by environmental conditions associated with exposure to abnormal elevated temperatures. Typical materials of a relay switch contact block include phenolic, wood flour phenolic, diallyl phthalate, Durez (brand name phenolic), and Page 9 of 83 I

Operability of Class 1 E Equipment in DG Rooms as a Result of a Loss of the Diesel Ventilation VD Fan polycarbonate. The results of a System 1000 query on these materials (Reference VIII.4, Attachment R) indicate that the highest aging temperature is a minimum of 140°C or the temperature rating is a minimum of 1 l5°C, meaning that the materials have been subjected to these temperatures without significant loss of material properties. As such, any thermal degradation experienced at l 15°C (239°F) is not expected to significantly impact the functionality of contact blocks constructed with these typical materials. Opened contacts will always experience some minute amount of leakage current at applied voltages. At elevated temperatures, there may be some increase in leakage current, however, that increase will be insignificant. Elevated temperature conditions coupled with humidity/moisture conditions may also increase leakage current, however, resistance in these circuits are sufficiently high such that any resulting leakage current across the open contacts remains insignificant when the relay is exposed to elevated temperatures and humidity/moisture conditions. Additionally, the CPS diesel generator equipment is located in a room where humidity conditions are less than 100% RH during normal and accident conditions (i.e., there are no pipe breaks postulated for the diesel generator room under accident conditions) when the equipment is operating. Therefore, failure due to leakage current is not a credible failure mode for the normally open relay switches installed at CPS. In summary, there is no credible failure mode for a normally de-energized relay switch exposed to abnormal elevated temperatures in less than 100% RH environment. V.2 Testing Performed at FAl Several components were subjected to baseline functional tests per KCI Test Specification 424-008-TSP2 (Reference VIII-3). Table V.2-1 summarizes the test results.

The control assembly was subjected to abnormal temperature exposure of 207°F for 24 hours, 225°F for 8 hours and 245°F for 8 hours. V.3 Impact of Elevated Temperatures on the CPS Emergency Diesel Generator The Emergency Diesel Generator (EDG) is designed to operate at an ambient temperature of 122°F (50°C) when the EDG is running and delivering the required power to the safety related equipment (Reference VIII. I). The DG room heat is removed by the VD fans and the fans are designed to keep the ambient temperature below 122°F. With the loss of the VD fan, the DG room ambient temperature is expected to rise above 122°F as the forced ventilation to remove the EDG heat is lost. The operability of all Class IE equipment required to function when the EDG is operating was evaluated for ambient temperatures of more than 122°F and documented in Reference VIII.2. It was previously established in Reference VIIl.2 that all Class lE equipment required for EDG operation will remain operable during the elevated DG room temperature of 140°F for a maximum period of 12 hours.

Operability of Class 1 E Equipment in DG Rooms as a Result of a Loss of the Diesel Ventilation VD Fan All the components located in the Division 1 EDG room has been identified and documented in Reference VIIl.5. All these components in Reference VIIl.5 are categorized as follows:

• Components in Yellow are identified as tripping interlock for the Div. I Diesel Generator (Not affected by LOCA Bypass) *
• Components in Pink are identified as tripping interlock for the Div. I Diesel Generator (Blocked by LOCA Bypass)
• Components in Light Green are identified as Starter interlock for the Div. I Diesel Generator (Not affected by LOCA Bypass)
• Components in Light Blue are identified with power regulation
• Components in White will not prevent EDG Operation After the EDG starts and runs continuously to supply _the power demand of all loads connected to the EDG, this report evaluates the impact of abnormal ambient temperature on the EDG to maintain its power production for 24 hours. Therefore, no other electrical faults are postulated during this period. Not all components in Yellow, Pink and Blue are required for the continuous operation of the EDG under the abnormal ambient temperature environment. These components are further divided into those components classified as "critical active" and "critical passive". The critical active components are capable of direct tripping or causing a trip of the EDG. The critical passive components do not cause a trip of the EDG but are capable of indirect tripping oftheEDG.

Table V-1 lists the temperature threshold for tripping interlock and power regulation components (Yellow, Pink and Blue) those are considered as "critical active" for a maximum duration of 24 hours. Table V-2 lists the temperature threshold for tripping interlock and power regulation components (Yellow, Pink and Blue) those are considered as "critical passive" for a maximum duration of 24 hours. Table V-3 lists the temperature threshold for non-critical components required EDG operation for a maximum duration of 24 hours, if applicable. Table V-4 lists non-critical components (White) not required for EDG operation. Components required for start-up (Green) and components that will not prevent EDG operation (White) are not required for continuous operation ofEDG. These components are re-evaluated and Table V-3 lists the temperature threshold for these Page 12 of 83

Operability of Class 1 E Equipment in DG Rooms as a Result of a Loss of the Diesel Ventilation VD Fan components for a maximum duration of 24 hours, if applicable. When reviewing Tables V-1, V-2 and V-3, note the following:

• The 23 °F cabinet temperature rise noted for various equipment types in Table V-1, V-2 and V-3 is based on actual measurements taken inside the DIV II (1PL12JB) control panel in 1991 when the ambient temperature was 74.5°F. This measurement is documented in calculation IP-Q-396 (Reference VIIl.2). Out of all the panels inside the DG room, Panel 1PL12JB (or 1PL12JA) is considered to have the maximum temperature rise. Components in three Panels (1PL92JA, 1PL93JA and 1DG06SA) are not required to function after the EDG starts. The remaining panels (lDGOlJA, lDGOlKA - 12 cyl EDG, lDGOlKA - 16 cyl EDG) have either very few components or components that are not normally energized. The major heat producing components (such motors, solenoids) in panels lDGOlKA are de-energized after the EDG starts. There are a few indicating lights that are energized in this panel. Therefore, the temperature rise inside this panel will be negligible, but assumed conservatively l 8°F in our analysis. The 10°C (18°F) temperature rise inside panel is taken from IEEE 649-1980 (IEEE Standard for Qualifying Class lE Motor Control Centers for Nuclear Power Generating Stations). This temperature rise for cubicles those are more compact have continuous energized contactors, control relays, control transformers, and circuit breakers. The CT/PT panel (lDGOlJA) has transformers, but these CTs and PTs do not dissipate significant power.

Therefore, a 23°F cabinet temperature rise is utilized for this panel conservatively.

• The equipment that was not in a panel (such as engine-mounted equipment) do not have a panel rise applied.
• Aging data or temperature threshold data stated are taken from Reference VIII.2 if not stated otherwise.

The minimum thermal Blue Generator life of Class F insulation is more than 1000 hours at 200°C operating temperature (Attachment T). The temperature rise at full load is 70°C (See Section 5. 12 of Ref. VIll.2). Based on TODI-CPS-17-025, the peak load on the EDG during the LOCAILOOP case is 3721 .2 KW and the peak load for the LOOP case is 3334.8 KW. The EDG is rated for 3900 KW continuous rating (DWG E02-IAPl2, Sheet 031 , Rev. J), the corresponding load for the LOCAILOOP and the LOOP is 95.4% and 85.5% respectively. Therefore the generator temperature rise at 95 .4% rated load is 63.7°C [70*0.954*0.954 = 63.7°C]. Assuming the same temperature rise, the generator will be exposed to 173.7°C when operating in an ambient temperature of230°F (110°C) [i.e., 110°C + 63.7°C = l 73.7°C]. The generator temperature will be l 8.7 °C above its long term rating of l 55°C. However, the generator is rated for 20,000 hours of operation at l 55°C and this life will be reduced by a factor of3 .66 using the 10°C rule for a long term life of more than 227 days. Therefore for a short term operation of I day, the impact on the generator thermal capability when operating at 230°F is negligible. The minimum thermal life of 1000 hours at 200°C from the ARC 87-00 report (Attachment T) also exceeds the Generator thermal stress for I da of o eration b a tar e mar in. E !DGOIKA G2 Exciter IDEAL 230 Exciter insulation is rated for l 55°C (Class F). The minimum thermal life Blue of Class F insulation is more than 1000 hours at 200°C operating temperature (Attachment T). The temperature rise of the exciter is 80°C (See Section 5.11 of Ref. VIII.2). The insulation life is 20000 hours at 155°C. For an operating envirorunent of 230°F (110°C), the exciter temperature will reach l 90°C. The life at this temperature is 1767 hours (73 days) using 10°C rule. Therefore for a short term operation of 1 day, the impact on the exciter thermal capability when operating at 230°F is negligible. The minimum thermal life of 1000 hours at 200°C from the C 87-00 report (Attachment T) also exceeds the Exciter thermal stress for I da of o eration b a lar e mar in . Page 18 of 83 I

K41X contacts drive 2 of2, engine over-speed shutdown solenoids L03 & L03A. This relay does not energize when the EDG is running normally and relay failure (contact failure) will not impact EOG operation. See OWG E02-IDG99 , Sht 011 (Rev . 0) This family of relays (Agastat 7012 series) was functionally tested while being aged at 225 °F energized at 125 VOC for 24 hours. The relay did not drop out or the open contacts did not short out. The relay was aged at 245 °F for another 8 hours and experienced drop out. The relay was then aged at 238°F energized at 125 VOC for 24 hours and did not experience drop out or short out. Since this relay is normally de-energized drop out or pick-up is not a concern and the relay will be good to 245°F. This relay is located in I PLI 2JA panel; accounting for a 23 °F cubicle temperature rise, the relay will not impact the EOG normal operation in an ambient temperature of222°F.

Located in 1PL!2JA panel. The LOR was aged at 257°F and therefore the coil insulation has a minimum temperature rating of 257°F. The relay has to pick up in the abnormal temperature environment. The pick up voltage for a 125 VDC coil is 40 VDC at room ambient temperature (See Attachment G) . The pick up voltage will increase by 42% at an operating temperature 257°F to 57 VDC which less than the avai lable voltage of 125 VDC. Accounting for a cabinet temperature rise of23°F, the relay will pick up at 234°F and trip the EDG. Note that this protective feature is not required for this scenario since the EDG is assumed to be running normally. E IPL12JA UY K34 Relay, Lockout GE 12HGA1 lJ 216 Located in panel I PL l 2J A. Under normal EOG operation, the Yellow DE Auxiliary 52 relay is de-energized. This relay is energized on overspeed to shutdown and lockout EOG. Under normal EDG operation, the relay contacts are open and two open contacts are in series with the lock out relay 86. Per SQ-CLD -068, the relay was aged at 2 l 2°F and functionally tested during an environmental test at 172°F. The open contacts due to dielectric failure of the contact block aided by moisture. The open contacts will not short circuit in an environment of 239°F (see Section V.1.3). Therefore, using the temperature limit of239 °F and accounting a 23 °F cabinet temperature rise, the relay will not impact the EDG normal operation in an ambient temperature of 2 l 6°F and will not provide a false trip to shutdown the EDG.

Operability of Class 1 E Equipment in DG Rooms as a Result of a Loss of the Diesel Ventilation VD Fan E Panel Comp Comp Description MFG PART NO Temperature Comment Importance State I Type Threshold M (*F) E IPLl2JA KL Relay, LOCA Bypass GE CR l 20BDO 222 This relay is a normally de-energized 125 VDC relay (Owg E02- Y ellow EIDE 4341 I OG99, SH 010) and installed inside panel I PLI 2JA. This relay is energized on the onset of a LOCA signal (RPV level or high drywell pressure) and the relay contacts are used as permissive for EOG operation. The relay pick up voltage measured by test at FAI under normal ambient temperature (20°C) is 74.1 VDC (see Attachment B). As the relay will be energized on the onset of EOG start (LOCA and/or LOOP), the relay will pick up. However, the relay will be exposed to extreme temperatures both from the temperature rise of the relay coil, abnormal temperature around I PLI 2JA panel and panel temperature rise of I PL I 2JA. Under this extreme temperature, the relay coil insulation should not lose its insulation dielectric strength for the coil to short circuit and the relay dropping out under the LOCA/LOOP or LOOP environment. The temperature rise of the relay at nominal terminal voltage of 125 VOC is I 8°C (32.4°F) [Reference Vlll.6, Attachment A]. The cubicle temperature rise for IPL12JA is 23°F. Assuming the panel IPL12JA to be exposed to 222°F after 24 hours of EOG operation, the relay coil will be exposed to a total coil temperature of277.4°F (222°F ambient + 23 °F cabinet temperature rise + 32.4°F relay coil temperature rise). The relay was aged at 280°F for 784 hours (Nutherm Report EGC-9785R, Rev. I , Page 33). The accelerated aging temperature of280°F is more than coil temperature of277.4°F. In addition, the coil magnet wire insulation is polyester with polyurethane (Nutherm Report EGC-9785R, Rev. I, Page 31) that is rated for 392°F (System 1000 material numbers 338, 340 and 551 , see Attachment 1-l). Therefore, the coil temperature capability exceeds the temperature inside the panel IPL12JA by I 14.6°F margin . The activation energy of the coil magnet wire insulation is 1.35 eV. Using Arrhenius equation, the aging time of784 hours at 280°F is equivalent to 897 hours (37 days) at 277 .4°F. Therefore, the relay coil wire will not degrade its electrical properties and relay will not de-energize in one day of EOG operation when the I PL! 2JA is exposed to 222°F. Note also that shou ld the relay drop out the EOG would continue to run unless other protective relays actuate, which does not need to be assumed for this scenario. E IPLl2JA  !

This relay bas a 50 Pink EN Time Delay second delay, which prevents false alarm indication and protective shutdown during startup due to low oil pressure or high engine coolant temperature. The K5 relay prevents tripping from S19A, S25A, Sl9 and S25 during the first 50 seconds (E02-IDG99 sht. 008 and 010). If the relay drops out it will simply prevent the tripping of the EDG due to high temperature or low pressure via S19A, S25A, Sl9 and S25 which is not an issue for a properly running EDG. See comment for Relay K41 . This family ofrelays (Agastat 7012 series) was functionally tested while being aged at 225°F energized at 125 VDC for 24 hours . The relay did not drop out or the open contacts did not short out. The relay was aged at 245 °F for another 8 hours and experienced drop out. The relay was then aged at 238°F energized at 125 VDC for 24 hours and did not experience drop out or short out. Since drop out of this relay would only serve to eliminate protective trips of the EDG, as stated above, the relay would not trip the EDG and the relay will not short at 245°F. This relay is located in 1PLl2JA panel; accounting for a 23 °F cubicle temperature rise, the relay will not impact the EDG normal operation in an ambient temperature of 222°F.

P). The A l 3 relay is energized with 125 VDC and relay Kl contact seal in the LPCS aod SX contacts that energized the Al3 relay (Dwg STC-4373, Rev. A aod Attachment M). Relay K2 and K3 are energized and a 90 ohms resistance (RI 5) is put in series with the RI I (automatic voltage control resistor for the Voltage Regulator) that increase the voltage across the exciter winding by the voltage regulator. After few seconds (based on the timing circuit ofQ2 aod Q5), the relays K2 and K3 get de-energized. After the K2 and K3 relays are de-energized, 65 ohms (R l6) comes in series with the RI I for normal EDG operation (Dwg STC-4373, Rev. A and Attachment M). This all happens with in few seconds after the EDG start when the temperature in panel I PL92JA is still normal. Based on SQ-CLD-049, the Al3 relay was thermally aged at l 25 °C (257 °F) for 78 days with no signs of degradation. It was functionally checked before and after aging. It was also functiona lly tested (i .e. cycled) while undergoing a thermal extremes test at 153°F. Therefore the relay will perform its fu nction after EDG starts. For continuous operation of the EOG, the open contact ofK3 relay should not short and R16 resistance should remain at 60 ohms. As the relay was aged at 257°F, the R 16 potentiometer wi II maintain its resistance. The open contacts will not short circuit in an environment of239°F (see Section V.1 .3). There is no panel temperature rise as there is no heat generating components in this local panel. Therefore the K3 relay will not short at a temperature limit of 239°F and Al3 relay will not impact the continued operation of the EDG. Page 49 of 83 I

There would be no change in frequency at elevated temperatures since the frequency is a function of engine RPM and number of teeth. The sensor is attached to the lower part of the engine which would be cool compared to the rest of the room since the engine coolant is maintained to - I 70°F. These types of sensors are robust and the operating temperature range of the device is -67 to 225°F (

Breaker Located in 1PL12JA panel. The LOR was aged at 257°F and therefore the coil insulation has a minimum temperature rating of257°F. The relay has to pick up in the abnormal temperature environment. The pick up voltage for a 125 VDC coil is 40 VDC at room ambient temperature (See Attachment G). The pick up voltage will increase by 42% at an operating temperature 257°F to 57 VDC which less than the available voltage of 125 VDC. Accounting for a cabinet temperature rise of23°F, the relay will pick up at 234 °F and trip the EDG.

Operability of Class 1 E Equipment in DG Rooms as a Result of a Loss of the Diesel Ventilation VD Fan VI Operability of Diesel Generator Starting Air System The subject Clinton Diesel Generator Starting Air Receiver Tanks (1DG04TA, B) are part of the Division 1 DG Air Skid (1DG06SA), as shown on drawing M05-1035, Sheet 1, Rev. AF. This assembly supplies air for the main engine starting system. These tanks are shown on vender drawing 61396, Rev P. As per the notes section of this drawing, these tanks have a design pressure of 300 psig and a design temperature of 300°P. The design temperature encompasses the maximum postulated event temperature of 174 °P. In addition, each of these tanks is protected against over pressurization by a pressure relief valve (1DG04TA, B), with a set relief pressure of 275 psig. Per passport, the vender drawing for the relief valve is C95760-34, Sheet 1, Rev. A. This valve is of metal construction with a Viton 0-ring as the only non-metallic part. Viton is a brand of synthetic rubber and :fluoropolymer elastomer commonly used in 0-rings. Compounds of Viton remain substantially elastic indefinitely when exposed to laboratory air oven aging up to 399 °P, per the manufacturer's web site (www.chemours.com/Viton/en US/assets/downloads/viton-selection-guide.pdf). Therefore, the relief valve will still function to prevent over pressurization of the subject air tanks during the postulated event. In summary, the Diesel Generator Starting Air Receiver Tanks will not rupture as a result of the postulated high temperature event; this is based on their design and the presence of a functioning pressure relief valve. VII Conclusion All components required for continuous operation of the EDG including the diesel generator itself will remain operable for 24 hours in an ambient temperature of 230°F except for components in panel 1PL12JA. Panel 1PL12JA components required for continuous operation of the EDG will remain operable for24 hours in an ambient temperature of 222°P.

Oven temperature will then be raised to 245°F and EUT's exposed to the elevated temperature for 8 hours. Functional tests will be performed after one hour of exposure to the elevated temperature at the end of the test cycle prior to removal from the oven. 4.1 Agastat Time Delay Relay (EUT-1) Baseline functional tests were performed in accordance with section 4.2.1 of the test specification. The average of three measurements for pickup voltage was 92.4VDC, for dropout voltage 24.1 VDC and the coil holding current 66mA. The relay timer was set to 50s and upon energizing the relay with 125VDC, the timer timed out and the normally closed contact opened. This contact was then monitored with a digital volt-meter (DVM) to ensure the contact remained open during the during the temperature exposure testing. The contact remained open for the 24 hour period at 225°F but the coil shorted out during the testing at 245°F. A new relay was configured in the same manner and exposed to 238°F for 24 hours and successfully completed this test. 4.2 Basler UFOV Assembly (EUT-2) & Basler Voltage Regulator (EUT-3) The voltage regulator and under voltage over frequency (UVOF) units were interconnected and powered by a 240VAC three phase source as described in Attachment A of the test specification. The connections to the generator field were simulated using light bulbs of approximately 500W. The frequency was decreased from 60Hz and the light bulb extinguished at 53.3Hz. The frequency was then raised back to 60Hz where the bulb re-illuminated at 53.9Hz. The voltage was then ramped up, at 245VAC the bulb extinguished. The voltage was returned to 240VAC and the bulb re-illuminated. During the abnormal temperature tests the light bulb remained illuminated indicating no under frequency or overvoltage signal occurred. Functional testing was repeated during the temperature excursions with results as follows:

The voltage phase angle was set to +30° and the current phase angle to 0° using the Doble F2253 and the light bulb wired into the circuit did not illuminate. The current phase angle was then stepped down in increments of -1 °. At -11 ° the relay operated and the bulb illuminated. The relay current phase was then set back to 0° and the relay was then exposed to 225°F for 24 hours and 245°F for 8 hours. During testing the light bulb did not illuminate indicating the relay did not operate. During testing the relay phase angle was again adjusted until a trip occurred illuminating the light. These results are as follows: Table 4-2 GE Loss ofExcitation Test Results Test Sequence Phase Angle 1 hour into 225°F test _90 End of 225°F test _go 1 hour into 245°F test _90 End of245°F test -60 4.4 GE Reverse Power Relay (EUT-5) The relay was wired and tested in accordance with the test specification Attachment E. The relay current coil carried 5.0A continuously and voltage coil was subjected to 120 VAC to simulate 95% generator load. The relay was de-energized and phase connections B and C flipped and when re-energized the monitoring light illuminated indicating the relay operated. The relay was then energized and subjected to 225°F for 24 hours and 245°F for 8 hours without the light illuminating thus indicating no false operation. At one hour into the 225°F test and at completion of this test the B and C phases were switched as described for the baseline functionals and the relay operated. At one hour into and at completion of the 245°F test the phases were switched and the relay operated.

A light bulb was wired into the circuit to monitor whether the relay operated. Current to the relay was . gradually increased until the bulb illuminated indicating the relay operated, the current value was llA. For the temperature testing at 225°F and 245°F 4.0A was supplied to the relay coil and the light bulb monitored. The light bulb did not illuminate thus indicating no false operation of the relay. 4.6 P&B Relay (EUT-7) Baseline functional tests were performed in accordance with section 4.2.6 of the test specification. The average of three measurements for pickup voltage was 73.4VDC, for dropout voltage 29.SVDC and the coil holding current 81.7mA. 125VDC was applied to the relay coil. An open relay contact was monitored to ensure the relay did not drop out throughout the temperature exposure. The contact remained open throughout the test at 225°F for the 24 hour indicating the coil did not drop out. The relay failed (dropped out) during the 245°F test.

4. 7 Phoenix Power Supply (EUT-8)

Baseline functional tests were performed in accordance with section 4.2. 7 of the test specification. The output voltage and voltage at 80% load current were measured three times and averaged. The value at no load was 24.lVDC and at 80% load current, 23.9VDC. For the abnormal temperature testing the power supply was energized with 125VDC with a load equivalent to 50% of the load carrying capability of the power supply. After one hour at 225°F the power supply shutdown. Power supply load was reduced to 20% and testing resumed at 225°F, however the power again dropped out. At this point, deviations from the test specification were provided. The oven temperature was lowered to 207°F and the load was maintained at 20% for 24 hours. With about 3 hours remaining the load was increased back to 50% and the test completed without further incidence. There was no testing at 245°F. 4.8 Westinghouse Differential Relay (EUT-9) The relay was wired in accordance with Attachment C of the test specification. SA was supplied to the restraint coil. The operating coil to each phase was increased until the relay operated. The operating currents where the relay operated were as follows: Phase A: 0.266A Phase B: 0.259A Phase C: 0.257A

EC 620632, Att. 1, Pg. 104 of 26~EPORTNO.:REP-424-008-RP1 REVISION: 03 FAI/17-0667 PAGE A21 of A23 Page 21 o/23 Rev. 0 July, 2017 The restraint coil to the relay carried 5A continuously and the operating coil, 0.22A. A bulb was placed into the circuit to monitor whether the relay operated. The bulb did not illuminate during the 225°F test or the 245°F test. The functional tests were performed on Phase A during exposure to 225°F. These tests consisted of increasing the phase A current until the relay tripped. The following are the results: Table4-3 Westinghouse Differential Relay Test Results Time During 225°F Test Phase A amps where relay tripped 1 Hour 0.247 3 Hour 0.220 24 Hour 0.243 4.9 Woodward Governor Control Assembly (EUT-10) The governor control system was configured as shown in Attachment F of the test specification. The governor actuator operates to protect the diesel generator unit from an over speed condition. A magnetic pickup monitors engine speed and operates an actuator to reduce engine speed on an over speed condition. The magnetic pickup was simulated with a function generator and the actuators with a 50 ohm resistor. At an input frequency of 3975Hz the voltage across the resistor was zero volts indicating no pickup of an over speed condition. The frequency was then raised to 4075Hz and the voltage across the resistor increased to 19.74VDC. The voltage returned to zero when the frequency dropped back to 3975Hz. During testing at 225°F and 245°F the voltage across the 50 ohm resistor was monitored with a DVM. The DVM showed zero volts with the function generator set to 3975Hz during the test indication that no over speed signal was generated. At one hour into the 225°F and 245°F test and at the end of both tests the frequency was raised to 4075Hz, the voltage recorded at 19.74VDC. The voltage returned to zero in all cases when the frequency dropped back to 3975Hz.

EC 620632, Att. 1, Pg. 116 of 267 REPORT NO.: REP-424-008-RP1 REVISION: 03 PAGE 810 OF 818 1.0 Background The 480V Bus IA sequencing control circuit relay logic for the 480 V Bus IA sequencing circuit recently demonstrated latent relay race for the VD fans. As the design does not provide stored DC relay energy to be dissipated, the logic is dependent on the relay parameters (i.e., coil inductance, coil time constant, drop out voltage and core air gap). The success of the logic sequence is limited by the drop out times of the two relays (GE CRI20BD0434I and Agastat E70I2PD004) and their drift of coil parameters over time. In this specific case, the relay parameters supported the logic sequence in the past before replacement of equivalent relays that may have introduced tolerances and a mismatch between the relay parameters that are causing a race in the logic sequence.

The EUTs were shipped from the Clinton Station and were brand new components. The receipt inspection was performed in accordance with Fauske & Associates Level 3 procedure F3-9.7-1 Visual Inspection. The receipt inspections demonstrated that the test specimens were not damaged during shipping and were in normal physical condition prior to the start of testing. No evidence of degradation, discoloration, or cracking was found during the inspection. The manufacturer and model numbers were identified and documented. Laboratory identifiers were assigned to the test specimens consistent with Table 3-1. This means that EUT #1 was assigned to one of the two available GE relays, EUT #2 was assigned to the second available GE relay while EUT#3 was assigned to the Agastat relay. Photographs of the test specimens were taken during the inspection. Photographs of the receipt inspection are found below. Figure 5-1 GE CR120BD04341 (1 of2) Receipt Inspection Photos-Side Views

The relay was allowed to cool but was not able to operate again. KCI was notified of this anomaly. EUT #2 was not utilized for the remainder of testing. BUT #1 and BUT #3 completed baseline functional testing without issues.

The relay circuit logic reproduced the Clinton Power Station logic sequence issue when energized and tested. Meaning, EUT #1 did not drop out after the 10 second time delay on BUT #3 occurred. The relay circuit logic sequence was unsuccessful each time the circuit was energized. Follow up tests were performed on the relay circuit. The tests consisted of 1) taking relay coil current measurements on both EUT #1 and BUT #3 during circuit operation and 2) measuring EUT #3 contact opening time. Coil current measurements were taken for both relays during the relay logic sequence. The minimum coil current measured for BUT # 1 was 16 mA. The expected minimum amount of coil current required for the relay to drop out was 1.4 mA. The minimum coil current observed for EUT #3 was 56 mA. The expected minimum amount of coil current required for the relay to drop out was 10.8 mA. These high coil current values suggest that the relay circuit design does not provide the stored energy in the relays to be properly dissipated. This delay in energy dissipation is long enough to allow the circuit logic to reset and initiate another 10 second time delay on BUT #3. Since BUT #1 did not drop out, the normally closed contact of BUT #3 was tested to observe if the contact would actually open even though both BUT #1 and BUT #3 were not dropping out. The contact opening time tests were performed on a normally closed contact on BUT #3. A 5 VDC signal was placed across one of the normally closed contacts on BUT #3 . The testing demonstrated that, after the 10 second time delay of BUT #3, the normally closed contact on BUT #3 would open for 25 milliseconds and return to its normally closed state. This means that despite the fact that BUT #3 does not drop out, the relay's normally closed contacts still operated

EC 62063 2 , Att. 1, Pg. 1 23 of 2 67 REPORT NO.: REP-424-008-RP1 REVISION: 03 PAGE 817 OF 818 as expected. Therefore, the operation of EUT #3's contacts is a mechanical action and not a result of the relay dropping out. 5.4 Manual De-eneq~ize Relay When EUT #1 is energized, the tip of the plunger moves outward. Manually pressing the plunger in an attempt to de-energize the relay required considerable force and was difficult to execute. Removal of the "+" wire to the 3 contact on EUT #3, the half coil wire connected to contact 4 on EUT #1, or the "-" wire to the EUT #1 coil would result in de-energizing EUT #1. 5.5 Thermal A~in~ Due to the relay circuit logic being unsuccessful at the onset of testing, thermal aging was not performed on the EUTs.

EC 620632, Att. 1, Pg . 124 of 267 REPORT NO.: REP-424-008-RP1 REVISION: 03 PAGE 818 OF 818 6.0 Conclusion When energized, the relay circuit logic tested in this report was not successful and reproduced the Clinton Power Station issue each time. Further tests demonstrated that both EUT #1 and EUT

       #3 do not drop out upon completion of the logic sequence due to the design not allowing the stored energy in the relays to be dissipated. EUT #3 mechanically operates its normally open/normally closed contacts after the 10 second time delay for 25 milliseconds before the relay resets back to its normally closed state due to the relay's inability to drop out. EUT #1 does not drop out within the 25 millisecond window due to the amount of coil current keeping the relay energized and allows the relay circuit to reset.

If the resulting underfrequency condition persists, damage may result to the electrical system as the SR voltage regulator attempts to mainta in rated generator output voltage. The Basler UFOV250A and UFOV260A are designed to protect the generating system against sustained low speed operation by reducing regulator output and, thereby, generator voltage. By addi ng the optional overvoltage circuit breaker, the generator-regulator system can be protected against overvoltage conditions . DESCRIPTION The UFOV250A and UFOV260A prevent the voltage regulator from maintaining rated generator voltage when generator frequency de-creases more than 4 to 7 Hertz below nominal value. When the underfrequency circuit assumes control, the reduction in generator SPECIFICATIONS output is proportional to the degree of the underfrequency condition. Page 2 When the frequency returns to nominal , the output of the SR regulator is automatically increased, thereby increasing generator output to nominal. To provide overvoltage protection, a circu it breaker is added to trip when the applied voltage exceeds a predetermined, adjustable ORDERING value (125%-150% of nominal). The circuit breaker contacts are con- Page 2 nected in series with the voltage regulator power input lines so that the SR regulator AC power (terminals 3 and 4) is removed when the breaker trips .

The testing also satisfies ANSI/IEEE CJ? .90-1989 and ANSI/IEEE C37 .98-1987. INTRODUCTION Lock-out Relays of various types are often used in the electrical power industry. These auxiliary relays are electric-trip, manual or electric-reset control relays for the purpose of tripping and locking out circuit breakers or other devices automatically when a fault or other pre-determined condition exists. Lock-out-relays are generally used in conjunction with protective relays to protect transformers, buses, and rotating machinery in various electrical systems. Fig. 2. Series 24 LOR/ER Electric-reset Lock-out Relay and LOR/SR Self-reset Lock-out Relay High-speed, rugged, multi-contact units are needed. This paper describes a family of Lock-out relays with up to 48 contacts that operate as quickly as eight milli-seconds and are seismic shockproof. BAS IC CIRCUIT OPERATION The control of the Lock-out Relays for operation as a relay requires no special wiring. They only require a N.O. contact (SI) to command the LOR to TRIP and the Electric-reset LORJER needs an additional N.0. contact Fig. l.

In addition, the TIME DELAY RESET version + LOPJSR has an additional IE-IF normally open (NO) contact to isolate the K2 coil plus the time delay circuit, consisting of RI and Cl-COK'mOL PACKAOE l C2-C3-C4, which are wired in parallel. DI protects the SUPPUB1 capacitors from a possible incorrect polarity hookup. The INSTANTANEOUS RESET version of the LOR/SR will reset itself within 80 milliseconds after the fault has cleared itself (SI opens). This circuit is illustrated in Fig. 5. Fig.6. Time-delay Self-reset circuit for the LOR/SR LOR/SR: Operating Voltage C:ONTHL The LOR, LOR/ER, and LOR/SR Lock-out Relays are PACOOE direct current actuated auxiliary relays. Because they are only SUPPUBI actuated for short periods of time and are self-interrupting, they may be subjected to maximum design voltage indefinitely without exceeding the 50°C temperature rise in ambient conditions as high as 55°C. This is using class 105 insulation and the applied thermo-couple method of temperature determination. Fig. 5. Instantaneous-reset circuit for the Self-reset The Lock-out Relays operate reliably over the full (shown in RESET position) Lock-out relay voltage ranges described in ANSI/IEEE C37.90-1989, the "Standard for Relays and Relay Systems Associated with Electric Power Apparatus ."

LOR interrupter contacts transients on the control bus up to 5kV. Since the LOR is normally isolated from the Bus, it will experience transients only if they occur in the operating mode. This precludes the possibility of a detrimental, accumulating effect over the life Fig. 9 typical LOR trip circuit with target of the unit. As such, no transient prote¢tion is needed. relay coil in series with LOR coil Because of the nature of the operation of the solenoid O>--~~~~~~~ coils, the LOR does generate transients that may be of interest

The gap is machine adjusted to provide a uniform high pressure. The gap does not change with time and use.

Normal use tends to improve the contact surfaces due to the rubbing action. This provides a burnishing as well as cleaning action. The contact surface conductivity is enhanced by a silver overlay stripe that lasts the life of the unit. This ensures a good contact, even in those cases where the LOR, LOR/ER, and LOR/SR are not operated for long periods of Fig. 14. Basic LOR Deck Layout time. The terminals are made of electrically and environ-mentally compatible copper material with a silver The illustration of Fig. 14 is for tl;ie first deck. For multi-overlay stripe at the contact area plus an overall silver deck units the second digit of the terminal number is the same plate to ensure a good, durable contact surface for customer as shown but the first digit changes to denote the deck wiring purposes. Similarly, the terminal screws are made number. As an example, terminal 82 is in the eighth deck, from silver-plated brass. directly under terminal 12 and used together with terminal 88.

Contact Deck Arrangement The blade and terminal configuration enables the use of multi-contacts in the same deck, and simple Fig. 15 . LOR, LOR/ER, and LOR/SR stacking procedures enable the fabrication of many Lock-out relay Chart independent contacts in one relay. Specifically, two NO contacts and two NC contacts are provided in each deck, and up to twelve decks can be stacked, resulting in a Contact Ratings relay with up to 48 contacts (24 N.O. and 24 N.C.). The The LOR, LOR/ER, and LOR/SR Lock-out relays have deck arrangement is illustrated in Fig. 14. been tested to many different circuit conditions. The interrupting ratings are based on 10,000 operations of life, The contacts operate reliably, using every contact and using suddenly applied and removed rated voltage, with no terminal illustrated. For good practice, however, it is extensive burning of contacts. Inductive ratings are based on suggested that polarized voltages having opposite polarity tests and using standard inductance L/R=0.04 for DC and should not be used on adjacent contacts. This is because of the remote possibility of flasho.ver during transition cos6=0.4 for AC. Short-time and cpntinuous ratings are between adjacent contacts ** especially at the higher DC based on temperature rise in contact members and ratings, or in highly inductive circuits. supporting parts not exceeding so 0c above ambient. 7

Manufacturing Company STEP 1 Determine Resistance and Watts Free Air Watt Rating In general, for commercial rheostats, the relation of the Ohm's Law "Free Air Watt Rating " of vitreous enameled rheostats to the physical size has been set at such a figure that: " When (a) R = Ell or I = E/R or E = RI operated at their rated watts the temperature rise of the hottest spot shall not exc~ed 300°C (540°F) as measured by Ohm 's Law, shown in formula form above, enables a thermo-couple, when the temperature of the surround-determination of the resistance when the required voltage ing air does not exceed /40°C (104 °F) . The temperature and current are known. When the current and voltage are is to be measured at the hottest point on the embedding unknown, or the best values not decided on, at least two material of a rheostat mounted on a vertical metal of the three terms in Ohm's Law must lie measured in a panel in free, still air space with at least one foot of clearance trial circuit (see Engineering Manual Bulletin 1100). to the nearest object, and with unrestricted circulation Note that the maximum current to be determined is the of air:' This is in accordance with standards of the "National current of the load before the rheostat resistance is Electrical Manufacturers Association" (NEMA) and the inserted. On the other hand, the maximum resistance " Underwriters' Laboratories:

• occurs with the minimum current. Electronic Industries Association (formerly RETMA) standards provide for a maximum attained hot spot tem-perature of 340°C for rheostats of 100 watts or less (b) W = 12R or W = El or W = E2/R and 300°C for rheostats of greater wattage. The reference Power, in watts, can be determined from the formulas above, ambient is 25°C.

which stem from Ohm's Law. Military Rheostat Specification MIL- R-22 provides for Note that the rated wattage of a uniform wound rheostat a maximum hot spot temperature attained (on the exposed is calculated using the maximum cu rre nt and the total winding) of 340°C for rheostats of 100 watts or less rheostat resistance. The Summation Watts are calculated and 390°C for larger rheostats. The reference ambient instead for a taper wound rheostat as explained under is 25°C.

   " Tapered Rheostats;* page 14.                                          The temperature rise, with all resistance in the circuit, is not directly proportional to the wattage but follows the curves as shown in Fig . 1 and Fig . 2.                         \

Short Cut Method Use an Ohm ite Ohm 's Law Calculator (convenient slide-chart) or use Ohm 's Law Chart in the Engineering Manual, Bulletin 1100. Set known values as explained on the Calcu lator, or Chart, and read the sought for OHMS, WATIS (or other terms) . Calculation Method Using the Ohm's Law formulas given above, and explained in greater detail in the Engineering Manual, calculate the unknown values. How to conduct tests when a trial must be made of the actual apparatus is explained in the Manual. STEP 2 Power Rating or Physical Size of Rheostat RHEOSTAT L OAO- PEACENT HAT ED WATTS Fig. 1: Hot spot temperature rise of a rheostat for various specifications. General: Rheostat watt ratings are based on the condition that the moving contact is set so that all of the winding is in the circuit. This makes the condition the same as that The temperature rise on a tapered rheostat does not of a fixed resistor (assuming a uniform rheostat winding) exceed the rated maximum, but the location of the hot and we may then say that a rheostat operated at a constant spot, for each position of the contact, depends on the wattage will attain a steady temperature which is deter- taper design. mined largely by the ratio between the size (surface area) In the usual rheostat application , the current is reduced and the wattage dissipated.

Hence, the zero resistance halves are not required (Fig. 53) and rheostat size may be approximately halved.

Sequence (2) Resolution of adjustment is significantly increased Coupling because control is possible over approximately 650 Dials degrees of rotation . (3) Sequence-coupled rheostats can be wound to provide, in combination, a taper; which permits a higher ratio of maximum to minimum current combined with high total resistance, than is otherwise feasible. A "sequence-coupling" dial and knob are available which provide a specific reading for every setting of the knob throughout its double (approximately 650 degree) rota-tion . Between the points where one rheostat stops and the other begins its rotation , the movable (calibrated) plate is tripped by a pin on the knob pointer. This plate shifts to expose one of two sets of numbers (0-100, or 100-200) through holes in the cover plate. The sequence coupling d ial assembly is held on the panel by four-self-tapping screws.

Fig . 84 (A) shows a method of using one rheostat to fade The size and resistance of the rheostat is determined between two lamp banks (both going out as the arm by the lamp to be controlled and the amount of dimming passes the center lead) . Figure 84 (B) shows a method desired. Because a larger rheostat or a tapered winding for gradually bringing a lamp from out to full on and back of more sections is needed for blackout than for 1% light, to out once every revolution. important economies can often be made if it is permissi-ble to open the circuit before blackout. It is strongly recommended that the minimum amount of light desired be determined by a substitution trial or by measurement with a photo-electric light meter, as visual estimates gen-erally are not sufficiently accurate. The curves in Fig . 83 show the per cent lamp current, (Al (8) voltage, and resistance, and the per cent required rheo-stat ohms for any percentage of dimming.

EC 620632, Att. 1, Pg. 1 REVISION : 03 Generator Field ControY 11°/Jeostats OHMITE Manufacturing Company Application: Ohmite Vitreous Enameled Rheostats pro-vide smooth, c lose, gradual control of generator voltage. The permanence of their characteristics, smoothness of operation, exactness of control, and compactness have made them first choice among generator and switchboard designers. By providing practically continuous variation of resistance in even the smallest sizes, they have made possible great savings in control-panel space. This makes them particularly useful on portable equipment, such as welding generators and power supplies. Range of Sizes: With a series of ten wattage sizes, there is an Oh mite rheostat, or tandem rheostat assembly, suit-able for every size generator in the range from the smallest to units of several hundred kilowatts. Individually Designed: Oh mite field rheostats will be individually designed by our Engineering Department to fit each generator field condition upon receipt of the following information : State whether self or separately excited, give field resistance (hot) , maximum field current (state at what volts for self-excited machines) , minimum field current, rheostat resistance (if known) . For Fig. 89: Typical field control rheostat, wire side view. self-excited mach ines it is desirable to supply a field magnetization curve. Standard Designs: The rheostats listed on the following

Proper alignment of the sensor is peak voltage (Vp-p). required. One complete waveform (cycle) occurs as each target passes Passive VRS (Variable Reluctance Speed) Magnetic Speed the sensor's pole piece. If a standard gear were used as a sensors are simple, rugged devices that do not require an target, this output signal would resemble a sine wave if viewed external voltage source for operation. on an oscilloscope. A permanent magnet in the sensor establishes a fixed Honeywell also offers VRS sensors for general purpose, high magnetic field. The approach and passing of a ferrous metal output, power output, high temperature and hazardous location target near the sensor's pole piece (sensing area) changes the applications, as well as low-cost molded versions. flux of the magnetic field, dynamically changing its strength.

Refer to Woodward manual 25071 In general, the oil used in the prime mover will be for more complete information on selection of oils satisfactory for use in the governor. for use in hydraulic actuators (governors). The governor/actuator oil supply is self contained. The oil selected should have a high viscosity Sump capacity is 1 1/2 quarts. When an empty index, within the -range of 100 to 300 SUS at governor is filled. add oil until it drains out the normal operating temperatures. Only oils of the vent hole in the sight glass. This should require grade specified for a particular temperature range about 47 ounces of oil. Immediately after starting should be used. and with the engine running, check the oil level in the sight glass. If the oil level is above the sight Figure 2-3 shows the viscosity of oils at the glass line, oil should be drained. If the oil level is different operating temperatures. Operating the below the line, add new, clean oil to bring the level governor with oil which does not fall in the up. acceptable operating range on the chart can

TECHNICAL BASES FOR NUMARC INITIATIVES NUMARC 87-00 Revision 1 G.2.3 Experience with Mechanical Equipment This section summarizes the available experience with motors and motor operated valve actuators at elevated temperatures.

G.2.3.1 Motor Experience Insulation is used in a motor to electrically insulate the windings from mechanical parts of the motor as well as to insulate the spaces between the turns of the coil winding. Also considered to be insulation are those materials used to secure the windings and to make them rigid and impervious to ambient conditions. There arc four basic classes of insulating materials currently recognized by the motor industry. Each differs according Lo its physical properties and can withstand a certain maximum operating temperature (frequently termed total temperature. or hot spot temperature) and provide a practical and useful insulation life. The insulation classes and their maximum operating temperatures are12,13: INSULATION CLASS RATED TEMPERATURE OF INSULATING SYSTEM CLASS A 900 c CLASS B 130°C CLASS F 1ss c 0 CLASS H 1so c 0 The thermal ratings for the insulating material in motor windings is assigned on the basis of a series of accelerated aging testsl4,15. In these tests the insulating system is exposed to temperatures significantly higher than those experienced during normal operation. Figure G .2* 11 shows actual tested time-temperature life for various insulation classes. The shaded area represents the range of experimental results obtained for the insulation classes. This figure demonstrates that even the most limiting insulation classes should be expected to function at ambient temperatures above 180° C for the limited duration of a four hour station blackoul G-29

EC 620632, Attachment 2, Page 5 of 254 Clinton Division 1 Diesel Generator NAI-2007-004 Room GOTHIC Uncertainty Revision 0 Evaluation Page 5 of47 1.0 Objective The purpose of this engineering report is to supplement the analysis of the Division 1 Diesel Generator room heat-up due to loss of the DG room emergency fan documented in Reference [8.14]. Uncertainty is present within that analysis as well as several modeling conservatisms discussed below. This engineering report evaluates the impact of removing some of those conservatisms for the purpose of generating a less-conservative, more best-estimate prediction of room temperatures within the Division 1 Diesel Generator room in order to determine room temperature margin. Cases 7, 10, and 12 documented in Reference [8.14] constitute the limiting room heat-up cases for the Division 1 Diesel Generator room following a loss of ventilation. Several conservatisms were implemented in those cases as discussed below:

1. The panels within the room were not modeled as enclosures. Instead, temperatures of the control volume cells that encompassed the panels were used to characterize the temperatures of the panels. Since the panel exists within an enclosure, the temperature of the affected panel equipment will be at a temperature lower than that of the ambient temperature.

2. As discussed in Section 4.4, the generator heat load was conservatively maximized and the engine heat load conservatively minimized.

3. Credit for air gaps to the outdoors was not credited.

4. The engine combustion air inlet piping, which would act as a heat sink, was not modeled.

5. Outdoor air was conservatively modeled at a constant value. Credit was not taken for the diurnal cycle. Furthermore, the temperature selected was conservative.

6. When the tank room exhaust fan (1 VD02CA) is operating, it will draw air in from the Division 1 DG room and from the fan room. The Reference [8.14] analysis under Input 2.3 conservatively assumed an even flow split between these two areas.

7. The heat load associated with the generator will be released and dispersed throughout the room mainly by the fans that are built into the generator. The Reference [8.14] model did not model generator heat release and dispersion in this manner. Heat was deposited into a single cell such that some of the heat would not be drawn up by the modeled generator fans. This is conservative, however, since the location where the heat was deposited coincided with one of the panels of concern.

The conservatisms will be examined and removed in this analysis in order to quantify the available margin and provide a more realistic room temperature heat-up. Specifically: July 25, 2017 9:40 AM EDT

EC 620632, Attachment 2, Page 6 of 254 Clinton Division 1 Diesel Generator NAI-2007-004 Room GOTEilC Uncertainty Revision 0 Evaluation - Page 6 of47

1. The panels within the room will be modeled as enclosures (i.e., control volumes with thermal conductors, and flow paths). Additionally, blockages will be included to ensure that the total free volume associated with the room is not over-estimated.

2. The generator heat load will be corrected to use a value consistent with vendor information. The engine heat load will be subsequently corrected by re-performing the benchmark outlined in Section 4.12 of Reference [8.14].

3. Credit for air gaps to the outdoors will be modelled.

4. The engine combustion air inlet piping, which would act as a heat sink, will be modeled.

5. Outdoor air will be modeled using a diurnal cycle and using a more representative peak daytime temperature.

6. For the flow split associated with the tank room exhaust fan (I VD02CA), a more realistic flow split will be utilized.

7. Generator heat load release and dispersion will be more accurately modeled.

Additionally:

• From the benchmark of the GOTHIC model to test data (Section 5. I of Reference

[8.14]), the GOTHIC calculated temperature near the transformer panel was under-predicted by approximately 7°F. From Reference [8.16], the cell that should have been selected for comparison to the test data is cell 39. This will be corrected.

• GOTHIC Bug AI 8.2-079a is addressed. Concerning AI 8.2-079a, for spanned external conductors, the total modeled conductor area of all the subconductors may differ from the specified value. A spanned external conductor is subdivided based on the relative exposed surface area in the connecting cells (for a general span) or the relative surface area in contact with the blockage associated with the spanned surface. If the exposed surfaces are consistent with conductor geometry, then the error in the modeled conductor area is negligible.

These changes will create the following models:

• CPS IA DG- Benchmark- a.GTH
• CPS IA DG LoV LOOP-LOCA Case 7a.GTH
• CPS IA_DG LoV LOOP-LOCA_Case lOa.GTH
• CPS IA DG LoV LOOP-TRANS Case I2a.GTH Lastly, Attachment C performs additional sensitivities on Case I Oa.

EC 620632, Attachment 2, Page 7 of 254 Clinton Division I Diesel Generator NAI-2007-004 Room GOTHIC Uncertainty Revision 0 Evaluation Page 7 of47 2.0 Inputs 2.1 GOTHIC Models The Benchmark, Case 7, Case 10, and Case 12 GOTHIC models are taken from Reference [8.14]. 2.2 Generator Heat Load Profile Generation Reference [8.17] transmits file "lA DG Loads_ZNE CorrectedJMF3.xlsx", which is used in the generation of generator heat load profiles. 2.3 Tank Room Exhaust Fan Flow Split from the Division 1 Room Recirculation and Supply Ductwork Reference [8.15] determines the air flow through the Division 1 Room as supplied by the Tank Room Exhaust Fan (1VD02CA) for the condition in which the lVDOlCA Supply Fan fails to start when demanded during LOCA and LOOP accident scenarios. The exhaust fan will pull flow from the supply ductwork and DG Room via the exhaust ductwork in the Division 1 Room associated with 1VDO1 CA. Between the supply and DG Room, Reference [8.15] indicates a flow split whereby 220 cfm of the flow is extracted from the outside through leakage across closed dampers and 2800 cfm of the flow is extracted from the Division 1 Room. 2.4 Atmospheric Conditions From Reference [8.17], the outdoor air peak daytime temperature is 90°F, the daytime temperature swing is l 7°F, and outdoor temperature as a function of time resembles a sinusoidal profile. The outside air design dry-bulb and mean coincident wet-bulb (1 %) temperatures for Decatur, Illinois are 90.6°F and 75.5°F, respectively, per Reference [8.3]. The dry bulb temperature is approximately the same as that provided by Reference [8.17], therefore the wet-bulb temperature of 75.5°F is used in conjunction with the 90°F outdoor air peak daytime temperature to develop a value for humidity. Using the psychrometric chart from Reference [8.3], the corresponding relative humidity is 50%. 2.5 Temperature Sensor Locations during Diesel Generator Testing Reference [8.13], Attachment A, shows the location of temperature sensors used during diesel generator testing (Reference [8.7], Attachment 6). 2.6 Exhaust Pipe Leakage A total leakage area of 1Oft2 was used in the analysis. One flow path was identified in Reference [8.15], which indicates that the leakage area around the Division 1 Diesel Generator exhaust pipe is 1Oft2 . This area is characteristic of the penetration through the DG room ceiling and the penetration through the roof. Additional leakage paths exist around doors, etc., but were not credited.

From Reference [8.15], the wall thickness ofthe piping is 3/8". 3.0 Assumptions 3.1 Reference [8.2], Input 4.3.1 conservatively reduces the free volume of the modeled rooms. It is assumed that no further reductions in free volume are required. 4.0 Methodology 4.1 Computer Code The GOTHIC version 8.2 (QA) computer code (Reference [8.1]) is used for this analysis. GOTHIC is developed and maintained under NAI's QA Program that conforms to the requirements of 10CFR50 Appendix Band 10CFR Part 21. Detailed descriptions of available GOTHIC user options and models are included in the user and technical manuals. Information about GOTHIC qualification is available in the qualification report. All known GOTHIC computer bugs are considered and dispositioned by this analysis. Transients were run on computer CARTSOl with an Intel Xeon E5-4650 processor running Windows Server 2012 Rev 2 Standard 64-bit, which is qualified to run GOTHIC 8.2(QA) under the NAI QA program. The GOTHIC 8.2 installation QA documentation is provided in Attachment A. 4.2 Adjustment of Tank Room Exhaust Fan Suction Flow Split from Supply and Recirculation Ductwork When the tank room exhaust fan (1 VD02CA) is running, it will draw in air through both the supply ductwork and the DG Room via recirculation ductwork in the Division 1 Room when the 1VDOlCA Supply Fan fails to start. From Input 2.3, 220 cfm of the flow is extracted from the outside and 2800 cfm of the flow is extracted from the Division 1 room. To implement this approach, the flow rate assigned to volumetric fan 8Q is changed to 2800 cfm. Since the flow rate assigned to the tank room exhaust fan (volumetric fan 2Q) is fixed at 3020 cfm, the balance of flow will be (220 cfm) will automatically be pulled from the outside since the associated network link, 7L, is not constrained. The way in which flow split is modeled is discussed in Section 4.7 of Reference [8.14]. July 25, 2017 9:40 AM EDT

EC 620632, Attachment 2, Page 9 of 254 Clinton Division 1 Diesel Generator NAI-2007-004 Room GOTHIC Uncertainty Revision 0 Evaluation Page 9 of47 4.3 Panel Modeling

• Panels were modeled using information from Reference [8.6]. Reference [8.6] provides panel dimensions and panel locations within the room, including distance off the ground for mounted panels and panels sitting atop pedestals. Control volumes for each panel were developed using this information. Given the relatively small space within each enclosure, it is assumed that the conditions within each panel will be homogeneous and so the associated control volumes are not subdivided. For added conservatism, the free volume is reduced by a value of30% (Input 2.7) to accommodate congestion within the panel.

Thermal conductors to represent each of the six walls of the panels are modeled using 11 gauge carbon steel material (Input 2.7). For thermal conductors that sit atop a concrete pedestal or are mounted to a concrete wall, a thermal conductor is not modeled since the concrete would be included in the thermal conductor type. The concrete would act as a heat sink and its exclusion is conservative. To ensure that free volume of the room is not over-estimated, blockages are modeled for each enclosure using information from Reference [8.6]. One vertical flow path is connected to the top of each control volume. Each flow path represents a 2mm leakage path to allow the control volume pressure to equalize with the pressure of the diesel generator room. As a control volume heats up or cools down, vapor will expand or contract causing changes in temperature which, in this application, is artificial. Allowing pressure to equalize prevents artificial compression heating. 4.4 Generator and Engine Block Heat Load The generator heat load is modeled using a fixed heat rate (i.e., independent oflocal conditions and a function of time only), implemented through the use of heater component 8H. A heat rate profile is supplied to that component using forcing function 3T. The basis for function 3T in the benchmark is developed in Reference [8.2]. For the analysis cases, the basis was originally provided by Input 2.1 of Reference [8.14]. The engine block heat load is modeled using thermal conductors 1 and 2 to represent "warm" and "hot" surfaces, respectively. Their thermal conductor type and surface area is based on physical characteristics of the engine. A bounding temperature is applied to the inside (i.e., engine-side) surface of these thermal conductors. The amount of heat rejected into the room will be a function oflocal temperatures. The heat transfer coefficient (surface option 6) applied to the outside (i.e., room-side) is determined through benchmarking (Section 4.12 of Reference [8.14]). This value is iterated during benchmarking to affect the total diesel generator heat load (i.e., the sum of the generator heat load and the engine block heat load) such that the room air exhaust temperature as calculated by GOTHIC is consistent with test data (Reference [8.7], ). July 25, 2017 9:40 AM EDT

EC 620632, Attachment 2, Page 10 of 254 Clinton Division I Diesel Generator NAI-2007-004 Room GOTIIlC Uncertainty Revision 0 Evaluation Page IO of47 It is conservative to allocate the total diesel generator heat load such that the generator heat load is maximized and the engine block heat load is minimized since the former is not dependent on room temperature and the latter is dependent on room temperature. As the diesel generator room heats up, the engine block will reject less heat into the room. The conservative value used in the original benchmark to characterize the generator heat load at a fully loaded condition is 153 Btu/sec per Reference [8.2]. From Reference [8.4], the quasi steady generator electrical output is 3747 KW. From Reference [8.8], pdfpage 18 of28, the full load power is 3900 KW and efficiency as a function of generator fractional loading is given for a power factor of 0.80 and 1.00. On pdfpage 19of28, the power factor is 0.80. For efficiency as a function of generator fractional loading, a curve fit is applied to the data points in excel to produce the following equation: 1J = -0.0413£ + 0.0878L + 0.9234 2 Equation 1 Where: T\ = efficiency (decimal) L = fractional loading Heat load as a function of time is then calculated using first principles: Equation 2 Equation 3 Q

EC 620632, Attachment 2, Page 11 of 254 Clinton Division 1 Diesel Generator NAI-2007-004 Room GOTHIC Uncertainty Revision 0 Evaluation Page 11 of47 At 3747 KW, the fractional loading is 0.961, the efficiency is calculated as 0.970, and the generator heat load is calculated as 111.227 Btu/sec. The steady state heat load value in forcing function 3T of the benchmark model is 153 Btu/sec, which is a conservative over-estimation of the generator heat load and

• conservative under-estimation of the engine block heat load. In other words, ifthe total diesel generator heat load is the sum of both the generator and engine block heat loads and, at steady state, is a fixed value, over-estimating the generator heat load requires the engine block heat load to be under estimated. However, it should be noted that the heat load value that corresponds to the end of the test (4920 seconds) in that forcing function is only 132.1 Btu/sec but that the heat load is assumed to increase to 153 But/sec at 4 hours per Reference [8.2], Table 5-2. It is this same heat load value of 153 Btu/sec upon which all accident heat load profiles are based per Reference [8.4] ..

In order to more accurately model the generator heat load value, the engine block heat load to the Diesel Generator room can be increased by at least 42 Btu/s (i.e. 153-111). The generator heat load (by the end of the test) is reduced to its nominal value of 111.227 Btu/sec. In order to conserve the total diesel generator heat load (total diesel generator heat load is generator heat plus engine block heat load), the engine block heat load must be increased, which is accomplished by increasing the overall heat transfer coefficient (U) to 5.158 Btu/hr-ft2-°F for the warm and hot portions of the engine. In doing so, the total diesel generator heat load approximately matches the test results by the end of the test (in actuality, it is slightly conservative) and, prior to that, is greater than the total diesel generator heat load indicated by the test, which is conservative. This is shown in Table 4-1. July 25, 2017 9:40 AM EDT

At 3800 KW, the required heat removal from the engine by the SX/DG heat exchanger based on vendor information (Reference [8.7], Attachment 3, page 3) is 50 Btu/min per KW, or 11.4 x 106 Btu/hr (3800KW x 50 Btu/minx 60 min/hr). The available heat removal for the 16 cylinder and 12 cylinder engines, according to their heat exchanger specification sheets (Reference [8.7], Attachment 2) is 13.37 x 106 Btu/hr (7.67 x 106 Btu/hr + 5.70 x 106 Btu/hr). The resulting margin is 1.97 x 106 Btu/hr (approximately 550 Btu/s) or approximately 15%. The degree of conservatism associated with generator heat load value of 153 Btu/sec will also be demonstrated using the existing GOTHIC models. It is noted that the use of 153 Btu/sec is used in the excel workbook provided by Reference [8.17] since it is the generator heat load upon which all accident heat load were developed as mentioned previously. The conservatism in the original Case 7, 10, and 12 analyses can be determined by correcting the generator steady state heat load to 111.227 Btu/sec and increasing the engine block overall heat transfer coefficient (U) to correct its heat load and affect the calculated exhaust temperatures to match test data exhaust temperatures. For the generator heat load, the heat load is reduced from 153 to the realistic value of 111.227 Btu/sec in the benchmark model by multiplying the dependent values of forcing function 3T by 0.72697 (111.227 divided by 153). In Cases 7, 10, and 12, the heat load is reproduced by using the excel workbook provided by Input 2.2. The excel workbook is modified to use a steady state heat load value of 111.227 instead of 15 3 and the resulting LOOP-LOCA and LOOP-TRANS heat load profiles are used to update forcing function 3T in Cases 7, 10, and 12. This is carried out as follows in the "lA DG Loads_ZNE CorrectedJMF3 .xlsx" workbook:

• On worksheet "LOOP-TRANS corrected", cells B2 through B23 are modified in that the value of 153 at the end of the cell formula is changed to 111.227.
• The LOOP-TRANS heat load profile is provided on the worksheet "LOOP-TRANS Table3" for use in forcing function 3T.
• On worksheet "LOOP-LBLOCA corrected", cells B2 through B23 are modified in that the value of 153 at the end of the cell formula is changed to 111.227.
• The LOOP-LOCA heat load profile is provided on the worksheet "LOOP-LBLOCA Table3" for use in forcing function 3T.

A re-benchmark is then performed following the method of Reference [8.14], Section 4.12. The resulting overall heat transfer coefficient (U) represents the corrected engine block heat load, which is used to update surface option 6 in Cases 7, 10, and 12. 4.5 Division 1 Diesel Generator Room Leakage Path A vertical flow path representing leakage around the diesel exhaust pipe is added to the model that connects control volume 1 (the Division 1 Diesel Generator room) to control July 25, 2017 9:40 AM EDT

The exhaust pipe penetrates the ceiling of the Division 1 Room as well as an additional ceiling slab per Reference [8.10] before being exposed to outdoor air. Reference [8.10] shows an additional enclosure at elevation 788' but identifies it as "air exhaust". It is therefore assumed that at elevation 788', the exhaust pipe is exposed to the atmosphere.

1. Reverse Loss 5.56 Same as forward loss coefficient Coefficient From the Reference [8.1] user manual, page 12-10, the flow path hydraulic diameter is used to calculate the wall friction head given by Equation 12.2 from the user manual:

fl pl Equation 5 M=--- Dh 2 Where: f = friction factor calculated by the GOTHIC solver 1 = friction length of the flow path Dh = hydraulic diameter p = fluid density in the flow path v = fluid velocity in the flow path The leakage flow path uses a friction length set to zero. All friction is modeled through the use of a loss coefficient equal 5.56, which bounds both wall friction head and form loss. Since the friction length is zero, the wall friction head will be zero for any hydraulic diameter. Therefore, the hydraulic diameter is set to an arbitrary value of 5 ft. 4.6 Combustion Air Inlet Piping The combustion air inlet piping is modeled using information from Reference [8.9], Section 8.12 (Input 2.8). Information is provided in that section on four thermal conductors that model combustion air inlet piping, which is adapted for use in this engineering report. The information used is as follows:

• The four thermal conductors added to the GOTHIC models in this engineering.

report are spanned across consistent x, y, and z-grid planes with respect to Reference [8.9], Section 8.12.

• The surface area assigned to each thermal conductor and conductor type is identical to those in Reference [8.9], Section 8.12.
• The parameters used to generate thermal conductor types for 36" and 24" piping are identical to the parameters used to generate thermal conductor types for 3 6" piping and 24" piping in Reference [8.9], Section 8.12.

It should be noted that Reference [8.16] indicates that the use of Reference [8.9] is acceptable. July 25, 2017 9:40 AM EDT

As the piping absorbs heat, the airstream temperature will increase. In order to bound uncertainty, the temperature of the air stream just as it enters the engine is applied to the inside surface of piping thermal cqnductors. This is calculated using a control variable as follows: Equation 7 Where: q = heat transfer through the piping thermal conductors (capture by the control variable) ri1 = combustion air mass flowrate (Ihm/sec) (input into the control variable) July 25, 2017 9:40 AM EDT

Since the first 5 seconds of the simulation is used to initialize thermal conductor temperature p~ofiles, thermal conductor heat transfer will be large enough to result in values of Thot that will cause the model to crash. Therefore, an intermediary control variable is used such that ifthe elapsed time is less than 0, q is set equal to zero (in other words, no correction is applied), otherwise it is calculated by GOTHIC. Both the calculated heat transfer coefficient and temperature are applied to the inside surface of the piping thermal conductors as a specified ambient and HTC surface option. Since the smaller diameter piping will split off the total intake flow, the smaller of the two calculated heat transfer coefficients (which corresponds to the larger diameter piping) is applied to all of the piping thermal conductors. For the outside of the piping thermal conductors, a new surface option is created. The surface option uses the direct heat transfer option, the default diffusion layer model (with film roughening) for condensation (condensation will not occur so this selection is inconsequential), the horizontal cylinder model for natural convection, and a user defined correlation for the forced convection option. Equation T8.14 on page 4.18 of Reference [8.3] provides the following Nusselt number correlation for external flow for cross flow over a cylinder: 518 4/5 Equation 8 0.62 Re 112 Pr 113 Re Nu=0.3+ [1 + (0.4 I Pr)"' J" 1+ (282,000) [ ] The correlation is applied through a surface option that implements the user defined option for forced convection. The Nusselt number is calculated through the use of control variables, which is applied to the surface option (GOTHIC will automatically back-calculate a heat transfer coefficient from the Nusselt number). The control variables are configured to pull local parameters (density, viscosity, cell-centered hydraulic diameter, cell-centered velocity, etc.) directly from the cells associated with the combustion air inlet piping thermal conductor in order to calculate a local heat transfer coefficient for each cell. 4.7 Outdoor Air Temperature The outdoor air temperature is varied over a 24 hour period using the following equation: July 25, 2017 9:40 AM EDT

EC 620632, Attachment 2, Page 19 of 254 Clinton Division 1 Diesel Generator NAI-2007-004 Room GOTHIC Uncertainty Revision 0 Evaluation Page 19 of47 2 Equation 9 T = Tmax -T.wing x (o.5 sin( m ) + 0.5J 24x3600 Where: T = temperature as a function of time Tmax =peak daytime temperature T swing = daytime temperature swing The peak daytime temperature is set to 90°F and the temperature swing is set to l 7°F (Input 2.4). Equation 9 is used to develop a temperature profile from 0 to 86,400 seconds in 60 second intervals, which is input into the model as forcing function 11 T and referenced by boundary conditions lP and 2F. The intent is to start and end the simulation with an outdoor air temperature of 90°F. From Input 2.4, the relative humidity is 50%. Since temperature will vary as a function of time, the relative humidity should be input as a steam volume fraction, otherwise GOTHIC will calculate the steam volume fraction using the time varying temperature and assuming a constant relative humidity of 50%. From Reference [8.2], atmospheric pressure is 14.3 psia. From Reference [8.3], page 30.41, the saturation pressure of water at 90°F is 0.699 psia. From Reference [8.3], page 1.12, equation 24, relative humidity is steam partial pressure divided by steam saturation pressure; the steam partial pressure is therefore 0.350 psia (0.5 times 0.699 psia). The steam volume fraction is 0.024 (0.350 I 14.3), which is input into boundary conditions lP and2F. 4.8 Diesel Generator Test Data Temperature near Transformer Panel Cell Correction From the benchmark of the GOTHIC model to test data (Section 5.1 of Reference [8.14]), the GOTHIC calculated temperature near the transformer panel is under-predicted by approximately 7°F. This is due to the temperature being extracted from the incorrect cell for use in comparison to the test data. From Reference [8.16], the cell that should be selected for comparison to the test data is cell 39, which the model is modified to reflect. 4.9 Generator Heat Release and Dispersion The heat load associated with the generator will be released and dispersed throughout the room mainly by the fans that are built into the generator. Modifications are made to the model to more accurately produce this effect. July 25, 2017 9:40 AM EDT

EC 620632, Attachment 2, Page 20 of 254 Clinton Division 1 Diesel Generator NAI-2007-004 Room GOTHIC Uncertainty Revision 0 Evaluation Page 20 of47 Flow paths 30 through 33 each contain a volumetric fan and simulate the generator fans. Flow paths 30 and 31 represent the bottom portion of the generator while flow paths 32 and 33 represent the top portion of the generator. The volumetric fans draw suction from* end A of these flow paths. Heater component SH is used to simulate the generator heat load and exists in cell 39. Flow paths 30 through 33, end A, are moved to this cell and their orientation is kept the same. The elevation of end A of these flow paths is changed to 742 ft and the height changed to 2.5 ft, which covers the entire height of cell 39. From the GOTHIC user manual, page 16-56, for a flow path with a volumetric fan, the flow through the-flow path is completely controlled by the fan specifications and the normal force balance for the flow path is bypassed. Therefore, these specifications for elevation and height are acceptable. By configuring the flow paths in this way, heat released by heat component SH will be drawn directly into the modeled generator fans and dispersed throughout the room, which is more realistic. 4.10 GOTHIC Bug AI 8.2-079a GOTHIC Bug AI S.2-079a is checked by opening one of the solver output files (.SOT) associated with any one of the model runs (i.e., CPS_lA_DG_Benchinark_a.SOT). Subconductors are listed in the "Conductor Input" section. The "Cond" column corresponds to a global index of all the subconductors. The "Base" column corresponds to thermal conductor number as seen in the Thermal Conductors table in the GOTHIC

• user interface. When a thermal conductor appears more than once in the "Base" column, it means that the thermal conductor is spanned and has been broken up into subconductors.

A thermal conductor is affected by GOTHIC Bug AI S.2-079a ifthe sum of the surface areas of its subconductors is significantly different than the surface area specified in the Thermal Conductors table. In other words, when a thermal conductor is "spanned", it is broken up into subconductors. The sum of the surface areas of those subconductors should be equal to the surface area of the thermal conductor as a whole. The surface area can be determined by summing the surface area values under the Side 1 "Surf A" and Side 2 "Surf A" columns. Side 1 refers to the A side of the thermal conductor while Side 2 refers to the B side of the thermal conductor. Conductor 9 is affected by this bug. Its subconductors add up to a value of 3237 ft2 but should add up to a value of2376 ft2 . Furthermore, the conductor represents the wall between the Division 1 and Division 3 rooms but is spanned to the wrong cells. First, spanning is corrected by assigning Side A of conductor 9 to the east wall of control volume 3 (the Division 3 room) and assigning Side B of conductor 9 to the west wall of control volume 1 (the Division 1 room). To correct the area, the surface area assigned to the conductor is changed to 2350 ft2 , the basis of which is through trial and error. With a value of 2350 ft2 assigned to conductor 9, the subconductor areas add up to 2376 ft 2 . July 25, 2017 9:40 AM EDT

It is noted that this value is consistent with typical heat transfer coefficient values for forced convection in gases per Reference [8.5], Table I.I (from 25 to 250 W/m2-°F or 4.4to 44 Btulhr-tt2-°F). This value is used to calculate the engine block heat load using 122°F as the ambient temperature for comparison to the vendor provided estimate of 2 Btu/min per KW similar to what was done in Table 4-2 -this is shown in Table 5-2, which shows that the resulting engine block heat load is conservative. Results of the benchmark are shown below in Figure 1, Figure 2, and Table 5-1. July 25, 2017 9:40 AM EDT

For instance, "TVlsl4" is the vapor temperature of cell 14 inside control volume 1. For lumped parameter volumes, "s#" will be absent. Compared to the results of Reference [8 .14], the maximum temperature of the hottest panel for each case based on cell temperatures compares as follows :

• Case 7 a is 31 °F lower than Case 7
• Case lOa is 28°F lower than Case 10
• Case 12a is 43°F lower than Case 12 Compared to the results of Reference [8 .14], the maximum temperature of the hottest panel for each case based on internal panel temperatures compares as follows :
• Case 7a is 39°F lower than Case 7
• Case 1Oa is 37°F lower than Case 10
• Case 12a is 49°F lower than Case 12 It should be noted that the original Case 7, 10, and 12 models did not model a separate control volume for the panels. The comparison provided is between the control volumes developed in this calculation and the hottest cell temperature reported in Reference [8.14]

based on cell temperatures. Of particular significance is the fact that all the original Case 7, 10, and 12 simulations predict closure of the fire dampers associated with the modeled ductwork early in the simulation. Cases 7a and 12a do not predict closure of the fire dampers and Case lOa predicts closure of the fire dampers in the last 4 hours of the simulation (Case 10 shows closure in the first 4 to 8 hours). This allows circulation through the ductwork to provide benefit to the Division 1 diesel generator room for a much longer period of time as compared to the original cases and is one of the main reasons why temperatures are significantly lower than those predicted in Reference [8.14].

Temperatures 6.0 Conclusions This engineering report supplemented the analysis of the Division 1 Diesel Generator room heat-up due to loss of the DG room emergency fan documented in Reference [8.14] by evaluating the impact ofremoving the conservatisms discussed in Section 1.0 for the purpose of generating a less conservative, more best-estimate prediction of room temperatures within the Division 1 Diesel Generator room in order to determine room temperature margin. July 25, 2017 9:40 AM EDT

EC 620632, Attachment 2, Page 46 of 254 Clinton Division 1 Diesel Generator NAI-2007-004 Room GOTIIlC Uncertainty Revision 0 Evaluation Page 46 of47 As was discussed in Section 5.2, removal of those conservatisms resulted in a decrease in panel temperature predictions, the smallest improvement being a 28°F decrease for Case lOa. Results of this evaluation can serve as input to a DG room survivability evaluation. Together, the GOTHIC analysis and component survivability evaluation can become input to a Probabilistic Risk Analysis (PRA) that supports a significance determination process associated with the loss of the Division 1 DG room emergency fan. As such, there are no further recommendations or suggestions for follow-up actions based on the conclusions of this engineering report. Each case was examined carefully and no anomalies of execution outside of Reference [8.2] and [8.15] limitations occurred. 7.0 Computer Files Table 7 GOTHIC Case Files File Name Description CPS lA DG Benchmark a.GTH Benchmark "a" GOTHIC File CPS lA DG LoV LOOP-LOCA Case 7a.GTH Case 7a GOTHIC File CPS lA DG LoV LOOP-LOCA Case lOa.GTH Case 1Oa GOTHIC File CPS- lA- DG- LoV LOOP-LOCA- Case- lOb.GTH Case 1Ob GOTHIC File CPS lA DG LoV LOOP-LOCA Case lOc.GTH Case lOc GOTHIC File CPS lA DG LoV LOOP-LOCA Case lOd.GTH Case 1Od GOTHIC File CPS lA DG LoV LOOP-TRANS Case 12a.GTH Case 12a GOTHIC File 8.0 References 8.1 GOTHIC Thermal Hydraulics Analysis Package, Version 8.2 (QA) October 2016. 8.2 MPR Calculation 0065-0061-CALC-001, Rev. 0, 5/22/17, "CPS Division 1 Diesel Generator Room Heat-up Evaluation due to Loss of Ventilation." 8.3 ASHRAE Fundamentals 2013 8.4 CPS-17-033 Rev. 0, CPS Transmittal of Design Information. 8.5 Incropera et. al, "Fundamentals of Heat and Mass Transfer", 6th Ed. 8.6 CPS-17-026 Rev. 0, CPS Transmittal of Design Information. 8.7 CPS-17-016 Rev. 0, CPS Transmittal of Design Information. 8.8 Clinton Vendor Technical Manual K2861A-0001, Rev. 0 8.9 Engineering Evaluation RWA-1716-001, Revision 0, "Red Wolf Associates Incorporation of Improvements and Enhancements to the Clinton Power Station July 25, 2017 9:40 AM EDT
