Vistra Operations Company LLC; Comanche Peak Nuclear Power Plant, Unit No. 1

The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of an amendment to Facility Operating License No. NPF-87, issued to Vistra Operations Company LLC (the licensee), for operation of the Comanche Peak Nuclear Power Plant (CPNPP), Unit No. 1. The proposed exigent amendment would revise CPNPP Technical Specification (TS) 3.8.4, ``DC [Direct Current] Sources--Operating,'' to allow the licensee additional time to replace two affected battery cells in the safety-related batteries for CPNPP, Unit No. 1. Specifically, the proposed one-time change would add a Required Action to TS 3.8.4, Condition B, to extend the completion time from 2 hours to 18 hours to repair each affected battery cell.
