Revise Technical Specification 3/4.3.2 to Remove Exemption from Testing Certain Relays at Power to Support Elimination of Potential Single Point Vulnerability - Withdrawal Waterford Steam Electric Station, Unit 3 NRC Docket No. 50-382 Renewed Facility Operating License No. NPF-38 In accordance with Title 10 of the Code of Federal Regulations (10 CFR) Part 50.90, "Application for amendment of license, construction permit, or early site permit," Entergy Operations, Inc. (Entergy) submitted a request (Reference 1) for an amendment to the Technical Specifications (TS) for the Waterford Steam Electric Station, Unit 3 (Waterford 3).
The proposed amendment revised TS 3/4.3.2 Table 4.3-2, "Engineered Safety Features Actuation System Instrumentation Surveillance Requirements," Table Notation (3), to remove the exemption from testing relays K114, K305, and K313 at power. U. S. Nuclear Regulatory Commission (NRC) provided acceptance review of the submittal on December 1, 2022 (Reference 2). The proposed change supports the Engineered Safety Features Actuation System (ESFAS) single point vulnerability (SPV) trip hardening modification which would reduce the likelihood of an inadvertent component actuation caused by a single failure.
Due to recently identified design issues, implementation of the ESFAS SPV Trip Hardening Modification has been postponed to a future date that has yet to be determined. In light of this schedule change, Entergy has elected to withdraw the proposed license amendment request.
