In Reference 1, NextEra Energy Point Beach, LLC (NextEra) submitted license amendment request (LAR) 279 to revise the technical specifications (TS) for Point Beach Units 1 and 2. The proposed change would eliminate TS 3.7.14, Primary Auxiliary Building Ventilation (VNPAB), on the basis that the VNPAB is not credited for accident mitigation and meets none of the criteria of 10 CFR 50.36 for inclusion in the TS. The purpose of this letter is to provide clarifying information to the technical evaluation included in LAR 279.
LAR 279, Section 3.2, Evaluation, discusses that NextEra provided a summary of the control room dose analysis performed without credit for the VNPAB system (Reference 3) in response to an NRC request for additional information regarding LAR 241, Alternate Source Term. The revised control room dose analysis without credit for the VNPAB system resulted in a control room total dose of 4.51 REM. Subsequently, NextEra submitted to the NRC another revision to the dose analysis (Reference 2), which updated the Reference 3 analysis, to incorporate a revised assumption regarding containment spray system operation. This revision to the dose analysis resulted in a final control room dose of 4.93 REM, which is the dose that _is included in the safety evaluation for the amendments that approved the use of alternate source term NextEra Energy Point Beach, LLC, 6610 Nuclear Road, Two Rivers, WI 54241
Document Control Desk Page 2 (Reference 4). The purpose of this letter is to clarify the difference between the control room dose value of 4.51 REM, which is the dose reported in Reference 3 without credit for the VNPAB, and the value of 4.93 REM, which is the value that resulted from the final revision to the dose analysis that supported the alternate source term license amendments.
This letter only provides clarifying information and does not alter the conclusions in Reference 1 that the proposed change does not involve a significant hazards consideration pursuant to 10 CFR 50.92, and there are no significant environmental impacts associated with the change.
This letter contains no new or revised regulatory commitments.
Should you have any questions regarding this submittal, please contact Mr. Bryan Woyak, Licensing Manager, at 920-755-7599.
I declare under penalty of perjury that the foregoing is true and correct.
