1.0 INTRODUCTION

By letter dated May 24, 2022 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML22144A018), as supplemented by letter dated October 28, 2022 (ML22301A152), Constellation Energy Generation, LLC (CEG, the licensee) submitted a license amendment request (LAR) for Nine Mile Point Nuclear Station, Unit 2 (NMP2). The proposed amendment would revise the Surveillance Requirements (SR) 3.8.1.2 associated with Technical Specifications (TS) Section 3.8.1, "AC Sources Operating," to reduce the number of fast starts of the emergency diesel generators (EDGs). Specifically, the Start Test and Fast-Start test requirements currently in SR 3.8.1.2 would be revised to identify SR 3.8.1.2 as only the "Start Test" requirements for the EDGs. A new SR 3.8.1.19 would be created to identify the "Fast-Start" testing requirements for the EDGs.

The supplemental letter dated October 28, 2022,1 provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the U.S. Nuclear Regulatory Commission (NRC or the Commission) staffs original proposed no significant hazards consideration determination as published in the Federal Register on September 6, 2022 (87 FR 54553).

1 The supplemental letter revises the written description of the proposed changes pertaining to the Notes for SR 3.8.1.2 and SR 3.8.1.19. Attachment 1 to the supplemental letter provides an updated Section 2.0 that supersedes Section 2.0 of the LAR in its entirety.

Enclosure 2

2.0 REGULATORY EVALUATION

2.1 System Design and Operation AC Sources - Shutdown The LAR Section 3.0 states, in part:

The Class 1E AC distribution system supplies electrical power to three divisional load groups, Divisions 1, 2, and 3, with each division powered by an independent Class 1E 4.16 kV emergency bus (refer to LCO 3.8.8, "Distribution Systems -

Operating"). The Division 1 and 2 (4.16 kV) emergency buses each have one separate and independent offsite source of power. The Division 3 (4.16 kV) emergency bus can be supplied by either offsite source. Each 4.16 kV emergency bus has a dedicated onsite DG. The ESF systems of any two of the three divisions provide for the minimum safety functions necessary to shut down the unit and maintain it in a safe shutdown condition.

The Division 1 and 3 (4.16 kV) emergency buses are normally supplied by the tertiary winding of reserve station service transformer 2RTX-XSR1A while the Division 2 (4.16 kV) emergency bus is normally supplied by the tertiary winding of reserve station service transformer 2RTX-XSR1B. Control power for the 4.16 kV breakers is supplied from the Class 1E batteries.

Each DG [diesel generator] must be capable of starting, accelerating to rated speed and voltage, and connecting to its respective ESF bus on detection of bus undervoltage. This sequence must be accomplished within 13.20 seconds. The 13.20 second start time includes the Loss of Voltage - Time Delay Function Allowable Value specified in LCO 3.3.8.1. Each DG must also be capable of accepting required loads within the assumed loading sequence intervals and must continue to operate until offsite power can be restored to the 4.16 kV emergency buses. These capabilities are required to be met from a variety of initial conditions such as DG in standby with engine hot and DG in standby with engine at ambient conditions. Additional DG capabilities must be demonstrated to meet required Surveillances, e.g., capability of the DG to revert to standby status on an ECCS signal while operating in parallel test mode. Proper sequencing of loads, including tripping of nonessential loads, is a required function for DG operability.

2.2 Proposed Change As stated by the licensee in the LAR:

The proposed change will revise NMP2 TS SR 3.8.1.2 to remove and relocate the "Fast-Start" test requirements for the EDGs into a separate SR. This proposed change will align NMP2 SR 3.8.1.2 with the "Start Test" described in section 2.2.1 of [Regulatory Guide (RG) 1.9, Selection, Design, Qualification, and Testing of Emergency Diesel Generator Units Used as Class 1E Onsite Electric Power Systems at Nuclear Power Plants, Revision 3 (ML003739929)],

and with SR 3.8.1.2 in [NUREG -1434, Standard Technical Specifications -

General Electric BWR/6 Plants: Specifications, Revision 5, Volume 1

(ML21271A582)]. The relocated "Fast-Start" testing requirements will be in a new SR (SR 3.8.1.19) and will align with the "Fast-Start" test [SR 3.8.1.7] as described in [NUREG-1434, Revision 5 and RG 1.9, Revision 3].

2.2.1 Changes to SR 3.8.1.2 The current SR 3.8.1.2 reads as follows:

---

NOTE--------------------------------

All DG starts may be preceded by an engine prelube period and followed by a warmup period prior to loading.

Verify each required DG starts from standby conditions and achieves:

a. In 10 seconds, voltage 3950 V for Division 1 and 2 DGs and 3820 V for Division 3 DG, and frequency 58.8 Hz for Division 1 and 2 DGs and 58.0 Hz for Division 3 DG; and

b. Steady state voltage 3950 V and 4370 V and frequency 58.8 Hz and 61.2 Hz.

Frequency: In accordance with the Surveillance Frequency Control Program SR 3.8.1.2 will be revised as follows:

---

NOTES-----------------------------

1. All DG starts may be preceded by an engine prelube period and followed by a warmup period prior to loading.

2. A modified DG start involving idling and gradual acceleration to synchronous speed may be used for this SR as recommended by the manufacturer. When modified start procedures are not used, the time, voltage, and frequency tolerances of SR 3.8.1.19 must be met.

Verify each required DG starts from standby conditions and achieves steady state voltage 3950 V and 4370 V and frequency 58.8 Hz and 61.2 Hz.

The frequency for this SR will remain as described in accordance with the Surveillance Frequency Control Program (SFCP).

2.2.2 New SR 3.8.1.19 The new SR 3.8.1.19 will read as follows:

---

NOTE--------------------------------

All DG starts may be preceded by an engine prelube period.

Verify each required DG starts from standby conditions and achieves:

a. In 10 seconds, voltage 3950 V for Division 1 and 2 DGs and 3820 V for Division 3 DG, and frequency 58.8 Hz for Division 1 and 2 DGs and 58.0 Hz for Division 3 DG; and

b. Steady state voltage 3950 V and 4370 V and frequency 58.8 Hz and 61.2 Hz.

The frequency for this SR will be in accordance with the SFCP [Surveillance Frequency Control Program].

In Section 2.0 of the supplemental letter dated October 28, 2022, the licensee states:

The proposed changes in this License Amendment Request (LAR) to separate the "Start Test" from the "Fast-Start" test will optimize the EDG testing strategy to minimize wear and tear on the EDGs. A modification will be implemented under the 50.59 process to support the testing changes. Until the EDG modifications are in place, EDG testing will continue with manufacturer recommended start procedures as defined in proposed Note 2 of TS SR 3.8.1.2.

In addition, the proposed change will delete a footnote related to current SR 3.8.1.2 on TS page 3.8.1-6 that reads, "*Following return to OPERABILITY of the HPCS System, the past due Surveillances will be completed by January 18, 2019," because the past due SR 3.8.1.2 was completed as part of the actions associated with the Emergency License Amendment No. 174 (ML18342A015, dated December 9, 2018) for a one-time extension to the Completion Time for LCO 3.5.1, Required Action B.2.

The supplemental letter dated October 28, 2022, provides clarification and addresses inconsistencies with the written description of proposed changes in Section 2.0 of the LAR to align with the proposed changes illustrated in the marked-up TS pages in Attachment 2 of the LAR. The supplement revises the written description of the proposed changes pertaining to the Notes for SR 3.8.1.2 and SR 3.8.1.19. Attachment 1 to the Supplement provides the revised Section 2.0 and supersedes Section 2.0 of the referenced document in its entirety.

2.3 Regulatory Requirements The following NRC requirements are applicable to the review of the proposed changes:

The requirements in Title 10 of Code of Federal Regulations (CFR) 50.36 Technical specifications, requires, in part, that TSs shall be included by applicants for a license authorizing operation of a production or utilization facility. The regulations under 10 CFR 50.36(c) require that TSs include items in five specific categories related to station operation. These categories are (1) safety limits (SLs), limiting safety system settings, and limiting control settings; (2) limiting conditions for operation (LCOs); (3) SRs; (4) design features; and (5) administrative controls. The proposed changes in this LAR relate to the SR

category. The regulation under 10 CFR 50.36(c)(3) states that Surveillance requirements are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met.

The following guidance documents are applicable to the proposed changes:

RG 1.9, "Selection, Design, and Qualification of Diesel-Generator Units Used as Standby (Onsite) Electric Power Systems at Nuclear Power Plants Revision 3, dated July 1993 (ML003739929), integrates the guidance of RG 1.108, Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants, Revision 1 dated August 1977 (ML003740376); RG 1.9, Revision 2, and GL 84-15, and it endorses, as appropriate, guidelines set forth in Institute of Electrical and Electronics Engineers (IEEE) Std 387-1984 "Selection, Design, and Qualification of Diesel-Generator Units Used as Standby (Onsite) Electric Power Systems at Nuclear Power Plants.

RG 1.155, "Station Blackout," dated August 1998 (ML003740034) discusses an acceptable method for determining the reliability of the diesel generator as one of the factors to be used to determine the length of time a plant should be able to cope with a station black out.

NUREG-1434, General Electric Standard Technical Specifications BWR/6 Plants Specifications, Revision 5, Volume 1, dated September 2021 (ML21271A582).

3.0 TECHNICAL EVALUATION

Section 2.2.1 in RG 1.9, Revision 3, provides the following test description for Start Tests:

Demonstrate proper startup from standby conditions, and verify that the required design voltage and frequency is attained. For these tests, the emergency diesel generator can be slow-started and reach rated speed on a prescribed schedule that is selected to minimize stress and wear.

Section 2.2.3 in RG 1.9, Revision 3, provides the following test description for Fast-Start Tests:

Demonstrate that each emergency diesel generator unit starts from standby conditions. If a plant normally has in operation, prewarm systems designed to maintain lube oil and jacket water cooling at certain temperatures or pre lubrication systems or both, this will constitute normal standby conditions for that plant. Verify that the emergency diesel generator reaches required voltage and frequency within acceptable limits and time as defined in the plant technical specifications.

Table 1 of RG 1.9 prescribes the test frequencies for the Start Test as a monthly surveillance, and for the Fast-Start Test at six month testing and every scheduled refueling outage period.

The proposed change will revise NMP2 TS SR 3.8.1.2 to relocate the "Fast-Start" test requirements for the EDGs into a separate SR. This change will align NMP2 SR 3.8.1.2 with the "Start Test" described in Section 2.2.1 of RG 1.9, Revision 3, and with SR 3.8.1.2 in NUREG -

1434, Revision 5. The relocated "Fast-Start" testing requirements will be in a new SR 3.8.1.19

and will align with the SR 3.8.1.7 as described in NUREG-1434, Revision 5 and RG 1.9, Revision 3. NMP2 SR 3.8.1.2 requires the EDGs to be periodically tested and currently includes both the "Start Test" and the "Fast-Start" testing requirements.

The NRC staff reviewed the proposed changes in the LAR that would revise SR 3.8.1.2 to describe only the "Start Test" requirements for the EDGs, moving the Fast-Start requirements to the proposed new SR 3.8.1.19. The changes to SR 3.8.1.2 include adding a second NOTE regarding modified starts. The NRC staff notes that there are no proposed changes to the voltage or frequency acceptance criteria for SR 3.8.1.2. The addition of Note 2 to SR 3.8.1.2 would allow for a modified, gradual EDG start in accordance with the manufacturer's recommendations. The licensee stated in the LAR that until the EDG modifications under the 10 CFR 50.59 process are in place, the EDG testing will continue with manufacturer recommended start procedures per proposed Note 2 of SR 3.8.1.2. The NRC staff finds the addition of Note 2 acceptable because the gradual start would minimize unnecessary stress and wear on EDGs due to testing, improving reliability so that the EDGs testing will assure the necessary quality of systems per 10 CFR 50.36(c)(3) and consistent with RG 1.9.

Additionally, the NRC staff reviewed the proposed change to remove footnote

• to SR 3.8.1.2 described above in section 2.2 of this safety evaluation. The footnote, added in License Amendment No. 174 dated December 9, 2018 (ML18342A015), was related to a one-time TS change for the Division 3 EDG maintenance, which supports the high pressure core spray (HPCS) system. The NRC staff finds the removal of the footnote, which expired in 2019, is acceptable because it is editorial in nature and clarifies the current requirements.

The NRC staff reviewed the proposed new SR 3.8.1.19 representing the Fast-Start test. The requirements in proposed SR 3.8.1.19 were relocated from current SR 3.8.1.2. The proposed changes to separate the "Start Test" from the "Fast-Start" test will allow the licensee to optimize the EDG testing strategy to minimize stress and wear on the EDGs. RG 1.9 prescribes a less frequent test interval for the Fast-Start test versus the Start Test. The NRC staff notes that there are no changes to the voltage or frequency acceptance criteria moved from SR 3.8.1.2 to new SR 3.8.1.19. The NRC staff finds proposed new SR 3.8.1.19 acceptable because other than the separation from SR 3.8.1.2, the new, less frequent EDG "Fast-Start" test interval (which will be performed in accordance with the SFCP) continues to meet 10 CFR 50.36(c)(3) and is consistent with RG 1.9.

Technical Evaluation Conclusion The proposed changes for NMP2 revise SR 3.8.1.2 to identify the "Start Test" requirements for the EDGs and relocate the "Fast-Start" testing requirements for the EDGs to a new SR 3.8.1.9.

These changes appropriately follow the guidance of NUREG-1434, Revision 5, and RG 1.9, Revision 3.

The NRC staff reviewed the NMP2 proposed TS changes and finds that NMP2 SR 3.8.1.2 and NMP2 SR 3.8.1.19 are consistent with the NUREG-1434, Revision 5 (SR 3.8.1.2 and SR 3.8.1.7, respectively). The proposed TS changes are in compliance with the requirements of 10 CFR 50.36(c)(3) and consistent with RG 1.9. Based on the above evaluation, the NRC staff concludes that the NMP2 TS proposed changes are acceptable.

4.0 STATE CONSULTATION

In accordance with the Commissions regulations, the New York State official was notified of the proposed issuance of the amendment on March 6, 2023. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and change surveillance requirements. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding published in the Federal Register on September 6, 2022 (87 FR 54553). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) there is reasonable assurance that such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
