Utility Radiological Safety Board L-20-291 Response to Request for Additional Information Page 1 of 3 By letter dated April 24, 2020 (Accession No. ML20115E517), Energy Harbor Nuclear Corp. submitted a license amendment request (LAR) for Nuclear Regulatory Commission (NRC) review and approval. By electronic mail dated August 14, 2020 (Accession No. ML20227A371), NRC staff requested additional information to complete its review. By letter dated September 29, 2020 (Accession No. ML20274A055), Energy Harbor Nuclear Corp. submitted a response to the request for additional information (RAI).
A conference call with NRC staff was held on October 15, 2020, in which the NRC requested clarification be provided on two of the responses, RAI-EEOB-01 and RAI-EEOB-04. Specifically, the NRC staff requested clarification on how the letter from the battery manufacturer supports the response to RAI-EEOB-01. In addition, the NRC staff requested clarification regarding the appropriate Category 'C' limit for float voltage per individual cell. Technical Specification (TS) Table 3.8.6-1 identifies the limit as greater than 2.07 volts (V) per individual cell, when the response to RAI-EEOB-04 states the Category 'C' limit for float voltage is 2.07 V per individual cell.
Updated RAI responses for RAI-EEOB-01 and RAI-EEOB-04 are provided below. The RAI is presented in bold type, followed by the Energy Harbor Nuclear Corp. response.
These responses supersede the previously provided responses.
RAI-EEOB-01 Section 2.2, "Verifications and Required Updated Safety Analyses Report
[UFSAR] Changes," of the LAR, the licensee stated that the PNPP Updated Safety Analysis Report will be revised to include, "How a 15 percent design margin for the batteries corresponds to a 2 amp float current value indicating that the battery is 92 percent charged for Division 1, 96 percent charged for Division 2, and 95 percent charged for Division 3."
Regarding the selection of float current limit (or return to service limit), TSTF-500 states:
One method of selecting the return to service limit that has been accepted by the NRC is reserving [5%] of the available design margin above that required to perform the intended design function.
The selected float current limit provides an indication that the battery is less than 100 percent charged, therefore the [5%] design margin is maintained to provide assurance that the battery is fully charged to perform its design safety function when the float current limit is reached.
L-20-291 Page 2 of 3 The NRC staff notes that the licensee does not discuss how the 15 percent design margin would ensure that the PNPP batteries would be fully charged at a 2-amp float current.
Explain how maintaining a 15 percent design for the batteries will ensure that the batteries are fully charged (i.e., capable of performing their design function) when the 2-amp float current limit is reached.
Response
For Division 1:
The battery is sized to account for a 1.25 aging factor and a 1.15 design margin. The entire 120-minute design basis scenario uses 300.02 amp-hours (AH) of the battery's 1260 AH nameplate rating, which equates to a 24 percent capacity discharge. Per the manufacturer, reduced capacity at the start of the design basis event due to the use of the 2-amp charging current criteria equaling 92 percent is acceptable. A battery at that capacity will still have ability to supply all required design basis loads for the 2-hour event.
For Division 2:
The battery is sized accounting for a 1.25 aging factor and a 1.15 design margin. The entire 120-minute design basis scenario uses 262.18 AH of the battery's 1260 AH nameplate rating, which equates to a 21 percent capacity discharge. Per the manufacturer, reduced capacity at the start of the design basis event due to the use of the 2-amp charging current criteria equaling 96 percent is acceptable. A battery at that capacity will still have ability to supply all required design basis loads for the 2-hour event.
For Division 3:
The battery is sized accounting for a 1.25 aging factor and a 1.15 design margin. The entire 120-minute design basis scenario uses 56.99 AH of the battery's 250 AH nameplate rating, which equates to a 23 percent capacity discharge. Per the manufacturer, reduced capacity at the start of the design basis event due to the use of the 2-amp charging current criteria equaling 95 percent is acceptable. A battery at that capacity will still have ability to supply all required design basis loads for the 2-hour event. A new letter from the battery manufacturer, dated October 30, 2020, is provided for clarification.
Therefore, maintaining a 15 percent design for the batteries will ensure that the batteries are fully charged when the 2-amp float current limit is reached.
L-20-291 Page 3 of 3 RAI-EEOB-04 The proposed new TS 3.8.6 Condition A would apply when one or two batteries on one subsystem is found with one or more battery cell(s) with a float voltage of less than 2.07 volts (V).
The NRC staff notes that the 2.07-V for the battery cell float voltage is bracketed in TSTF-500. The battery cell float voltage limit should be greater than or equal to the battery open circuit cell voltage to ensure that the battery is not discharging.
A battery cell voltage below the open circuit cell voltage indicates that the cell is discharging. It appears that the basis for the proposed 2.07-V limit for the PNPP battery cell float voltage was not provided.
Discuss the basis for the 2.07-V limit for the PNPP battery cell float voltage. In the discussion, provide the batteries' open circuit cell voltages.
Response
At PNPP, the battery is designed and sized to support all design basis loads and duty cycle whenever battery Category 'C' limits are as defined by the current approved TS Table 3.8.6-1. The Category 'C' limit for float voltage is greater than 2.07 V per individual cell. This would equate to an open circuit voltage of 126.27 VDC for Division 1 and 124.2 VDC for Divisions 2 and 3 batteries. As such, the use of the greater than 2.07 V limit as part of TSTF-500 is not a change from the existing PNPP TS open circuit cell voltage.
The proposed new TS 3.8.6 Condition A should apply when one or two batteries on one subsystem is found with one or more battery cell(s) with a float voltage of less than or equal to 2.07 V. Therefore, new mark-up pages of existing TS and revised (clean) TS pages are provided to supersede the previously provided pages.

Enclosure Letter from Battery Manufacturer Verifying the Acceptability of Using Float Current Monitoring
C::DTECHNOLOGIES, INt Pow e r Solu ti ons Sent via Email to: jpetty@firstenerqycorp.com October 30, 2020 Mr. Justin Petty First Energy Corp.
Subject:
Perry Nuclear Plant - Using Float Current for State of Charge
Dear Justin:
1400 Union Meeting Road Blue Bell, PA 19422 Phone: (215) 775-1306 Fax: (215) 619-7887 In regards to the C&D battery model KCR-7 in safety related (Class 1-E) applications at Perry, it is acceptable to use float current monitoring and cell voltage instead of specific gravity monitoring as a reliable and accurate indication of the state of charge of the battery. This relationship remains valid for the life of these batteries.
If you are charging the KCR-7 batteries between 2.20 and 2.25 volts per cell, then once the cells are within this voltage range and the charge current reaches 2 amps, you can consider that 95% of the charge has been returned. If you have at least 5% margin to meet your duty cycle, then 2 amps can be used as criteria for returning the battery to service.
For technical basis, please reference IEEE 450-2010, Annex A.2, which indicates in part:
A.2 Stabilized charging current used to determine a fully charged condition The pattern of charging current delivered by a conventional voltage-regulated charger after a discharge is the most accurate method for determining the stale of charge. As the cells approach full charge, the battery voltage rises to approach the charger output voltage, and the charging current decreases. When the charging current has stabilized at the charging voltage for three consecutive hourly measurements, the battery is near full charge. The expected charging current range applicable to each model may be verified by test or in consultation with the manufacturer.
I hope that this information meets your needs. If you require any additional information, please contact me.
