Grand Gulf - Official RAIS for Relief Request GG-ISI-023, Inservice Inspection Impracticality, Limited Coverage Examinations During the Third 10-Year Inservice Inspection Interval (EPID L-2018-LLR-0197)

By letter dated November 30, 2018 (Agencywide Documents and Access Management System Accession No. ML18334A246), Entergy Operations, Inc. (the licensee) 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 (RR) GG-ISl-023 pertains to examination coverage of the Class 1 piping and vessel welds in the third 10-year inservice inspection (ISI) interval of the Grand Gulf Nuclear Station, Unit 1.

To complete its review, the U.S. Nuclear Regulatory Commission staff requests the following additional information:

1. Please provide the operating temperature and pressure for each piping weld listed in GG-ISl-023 (i.e.,

Examination Category R-A).

2. Were there any additional piping welds composed of same material and exposed to similar environment examined in the third 10-year ISI interval to provide additional inspection coverage? Please discuss.
3. Given the limited coverage achieved for the subject piping welds (i.e., ranging from 50 percent to 87.7 percent), please provide a summary of the evaluation for accepting the proposed limited coverages required by Note 3 of Table 1 in ASME Code Case N-716 Alternative Classification and Examination RequirementsSection XI.

We transmitted the draft requests for additional information (RAIs) for the subject RR on March 11, 21019, and you replied on March 19, 2019 that no clarification call is required. Please find the above official RAIs for the subject RR, and provide your responses within 30 days from the date of this email.
