SUBJECT:

OCONEE NUCLEAR STATION - NOTIFICATION OF INSPECTION AND REQUEST FOR INFORMATION FOR NRC PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION

Dear Mr. Burchfield:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)

Region II staff will conduct a problem identification and resolution (PI&R) inspection at your Oconee Nuclear Station during the weeks of April 26-30, 2021, and May 10-14, 2021. The inspection team will be led by Mrs. Jannette Worosilo, a Senior Project Engineer from the NRCs Region II office. This inspection will be conducted in accordance with the baseline inspection procedure, 71152, Problem Identification and Resolution, issued February 26, 2015.

The biennial PI&R inspection and assessment of the licensees Corrective Action Program (CAP) complements and expands upon the resident baseline inspections of routine daily screening of all corrective action program issues, quarterly focused issue reviews, and semiannual trend PI&R reviews.

On February 10, 2021, Mrs. Jannette Worosilo confirmed with Mrs. Sheila Dalton, Licensing, of some details and expectations for the two weeks of the inspection.

The enclosure lists documents that will be needed prior to the inspection. Please have the referenced information available no later than March 31, 2021. Contact Mrs. Jannette Worosilo with any questions concerning the requested information. The inspectors will try to minimize your administrative burden by specifically identifying only those documents required for inspection preparation.

If additional documents are needed, they will be requested when identified. Prior to the inspection, Mrs. Jannette Worosilo will discuss with your staff the following inspection support administrative details: availability of knowledgeable plant engineering and licensing personnel to serve as points of contact during the inspection; method of tracking inspector requests during the inspection; and other applicable information.

J. Burchfield 2 In response to the COVID-19 coronavirus and updated Federal Government guidance on travel and social distancing, the NRC inspection team is prepared to conduct this inspection accordingly. Therefore, in support of this inspection some, or all, of the inspection team may perform their reviews with minimal onsite staff interaction or remotely as conditions permit.

The NRC inspection team requests that your staff be prepared to support these efforts. Additionally, the inspection team is open to any suggestions regarding communications and coordination such that the overall effort from both the NRC inspection team and Duke support staff may be the most efficient while also prioritizing public health and safety.

In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 of the NRCs Rules of Practice, a copy of this letter will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Thank you for your cooperation in this matter. If you have any questions regarding the information requested or the inspection, please contact Mrs. Jannette Worosilo at (404) 997-4485.

Sincerely,

/RA/
