Dear David Rhoades:
This letter confirms the discussion between me and members of your staff to meet and discuss the risk significance of the preliminarily greater than green finding and the associated apparent violation involving the apparent failure to identify and correct a fuel oil leak on the 2B auxiliary feedwater pump diesel engine for approximately 127 days. The preliminary finding and apparent violation are discussed in NRC Inspection Report 05000457/2023011, dated January 23, 2024 (NRCs Agencywide Documents Access and Management System [ADAMS] Accession No. ML24022A100). The meeting will begin at 8:00 a.m. CST on Thursday, March 7, 2024, at the US Nuclear Regulatory Commission Region III Office located at 2443 Warrenville Road, Suite 210, Lisle, IL 60532. This meeting is open to the public.
