Entergy Fleet (Grand Gulf and River Bend) - Relief Request (RR) Associated with ASME Code RR Safety Evaluations with NRC-Approved Revision of BWRVIP Guidelines (GG-ISI-020 and RBS-ISI-019) (EPID L-2020-LLR-0079)

During our Grand Gulf bi-weekly status call this afternoon, you proposed the path forward for the subject relief request for resolving NRC staffs concerns regarding the use of BWRVIP-41, Revision 4 for Grand Gulf without verification of catalyst loading, which will not satisfy all the BWRVIP-62-A, Table 3-8 implementation steps for hydrogen water chemistry inspection relief at Grand Gulf. You mentioned that Entergy is planning to take fuel sampling in June 2021 at Grand Gulf, and expect to complete verifying catalyst loading four to six weeks later, i.e., by August 2021. You will then provide the results to NRC by a supplemental letter. We accepted your proposal conditionally requiring verification from our management because of exceeding one-year metrics by NRC for this relief request. Our management agreed to your proposal. In this mean time, you agreed to provide a supplemental letter shortly, providing all the details of the proposed plan including the estimated dates of your two supplemental letters.

The NRC staff will review your final results of catalyst loading for Grand Gulf and then make a decision at that time. The main technical reviewer has plans to retire in May 2021, and this may require few more hours for the new technical reviewer. Once we receive your first supplemental letter to delay NRC action on the subject relief request, we will provide you a new estimated date to complete our final review and additional hours needed by revising our acceptance email that was transmitted to you on January 14, 2021 (ADAMS Accession No. ML21015A345).

If you have any questions, please feel free to contact me.

Thank you.
