JOSEPH M. FARLEY NUCLEAR POWER PLANT UNITS 1 AND 2 - PLANT REFERENCE SIMULATOR INSPECTION REQUEST FOR INFORMATION

Dear Mr. Kharrl:

In April and May 2020, the U.S. Nuclear Regulatory Commission (NRC) will perform an inspection of the Joseph M. Farley Nuclear Power Plant with the onsite inspection tentatively planned for May 26 through 27. The newly installed simulator is built on a slightly different platform and has a slightly different I/O system than the existing platform. Therefore, the inspection will verify whether or not the newly installed plant referenced simulator is designed and implemented so that it is enough in scope and fidelity to be suitable for conduct of the evolutions listed in 10 CFR 55.45(a)(1) through (13), and 55.59(c)(3)(i)(A) through (AA) using NRC Inspection Procedure (IP) 41502, Nuclear Power Plant Simulation Facilities.

This inspection is resource-intensive for both the NRC inspectors and your staff. To minimize the impact to your onsite resources and to ensure a productive inspection, we have enclosed a request for documents needed for this inspection. It is important that all these documents are up-to-date, and complete, to minimize the number of additional documents requested during the preparation, and/or the onsite portions of the inspection.

We have discussed the schedule for these inspection activities with your staff. We understand that our regulatory contact for this inspection will be Michael Galle (334-661-2691; mkgalle@southernco.com) of your organization. If there are any questions about this inspection or the material requested, please contact the lead inspector, David Lanyi at 404- 997-4487 (david.lanyi@nrc.gov), or the Chief, Operations Branch 2, Eugene Guthrie at 404-997-4662 (Eugene.Guthie@nrc.gov).

C. Kharrl This letter and its enclosure will be made available for public inspection and copying at https://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, and Requests for Withholding.

Sincerely,

/RA/

Eugene F. Guthrie, Chief Operations Branch 2 Division of Reactor Safety Docket Nos.: 05000348 / 05000364 License No.: NPF-2 / NPF-8

Document Request List Inspection Dates: May 26-27, 2020 Inspection Procedure (IP): 41502, Nuclear Power Plant Simulation Facilities Note: This is a list of the documents to be provided to the inspectors. The current version of these documents is expected unless specified otherwise. The documentation will be requested in two batches. The first batch will consist of all Plant Simulator Program Procedures and a list of all completed simulator tests, a list of all open and closed simulator Deficiency Reports, and a listing of all applicable simulator related Training Needs Assessments or Evaluations. The second batch of information will be a smart sample chosen by the inspectors from the list provided in the first batch.

The preferred file format is Word or searchable .pdf files on CDROM or CERTREC. [Note that the inspectors cannot accept data provided on USB or flash drives due to NRC IT security policies It is not the intent that large or burdensome data be scanned for this. This data will be inspected using original documentation. Material can be provided prior to the inspection via Southern Companys ftp site.
