SUBJECT:

GRAND GULF NUCLEAR STATION - NOTIFICATION OF NRC SUPPLEMENTAL INSPECTION OF ACTION MATRIX COLUMN 3 (DEGRADED PERFORMANCE) INPUTS AND REQUEST FOR INFORMATION

Dear Mr. Franssen:

In a letter dated June 22, 2021, you informed the U.S. Nuclear Regulatory Commission (NRC) that the Grand Gulf Nuclear Station was ready for the NRC to perform a supplemental inspection in response to degraded performance that led to the facility being moved into Column 3 of the Action Matrix. The inspection will be conducted in accordance with NRC Inspection Procedure (IP) 95002, Supplemental Inspection Response to Action Matrix Column 3 (Degraded Performance) Inputs. The on-site inspection is scheduled to be performed August 23 through September 3, 2021.

In order to ensure a productive inspection, we have enclosed a request for documents needed for this inspection. The documents identified are those that will be needed by the inspectors prior to their arrival for the on-site for the inspection. It is important that all of these documents are up-to-date and complete in order to minimize the number of additional documents that may be needed to support the inspection. If possible, we would request that this information be provided electronically. Any material that is not available electronically should be printed and available for the first day of on-site inspection activities.

We have discussed the schedule for these inspection activities with your staff. If you have questions regarding our schedule or the material being requested, please contact April Nguyen at (630) 829-9587. She may also be reached electronically at April.Nguyen@nrc.gov.

R. Franssen 2 In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records System (PARS) component of NRC's Agencywide Documents Access and Management System (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
