River Bend Station, Unit 1 - FINAL Request for Additional Information Re: Relief Request RBS-ISI-021 (EPID L-2018-LLR-0388)

Final Request for Additional Information On April 8, 2019, the U.S. Nuclear Regulatory Commission (NRC) staff sent Entergy Operations, Inc. (the licensee) the draft Request for Additional Information (RAI) provided below. This RAI relates to Relief Request RBS-ISI-021 for River Bend Station, Unit 1 (RBS).

The licensee subsequently informed the NRC staff that the information requested by the NRC staff was understood and no additional clarification on the RAI was necessary. Mr. Jones agreed to provide a response to this final RAI within 30 days from the date of this correspondence. The NRC staff also informed the licensee that a publicly available version of this final RAI would be placed in the NRCs Agencywide Documents Access and Management System).

By letter dated November 30, 2018 (ADAMS Accession No. ML18334A259), Entergy Operations, Inc.

requested relief in accordance with Title 10 of the Code of Federal Regulations (10 CFR) 50.55a(g)(5)(iii) from the requirement of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code),Section XI. Relief Request RBS-ISI-021 pertains to examination coverage of the Class 1 piping and vessel welds in the third 10-year in-service inspection (ISI) interval at RBS. The NRC staff requires additional information to complete its review of this request as detailed below.

1. The Class 1 piping and vessel welds did not meet the ASME Code-required examination coverage in Table IWB-2500-1, Footnote 3 for B-J category piping. To determine the extent of condition, were there any piping welds (composed of the same material and exposed to a similar environment) examined at the ASME Code-required coverage with acceptable results in the third 10-year ISI interval? Please discuss.

2. Given the limited coverage achieved for the subject piping welds, provide a summary of evaluation for accepting the proposed limited coverages, required by Note 3 of ASME Code Case N-716, Alternative Piping Classification and Examination RequirementsSection XI, Division 1.
