SUBJECT:

BRUNSWICK STEAM ELECTRIC PLANT UNIT 1-NOTIFICATION OF NRC SUPPLEMENTAL INSPECTION (IP 95001) AND REQUEST FOR INFORMATION

Dear Mr. Gideon:

By letter dated May 15, 2019, the U.S. Nuclear Regulatory Commission (NRC) communicated to you the updated assessment of Brunswick Steam Electric Plant, Unit 1. The NRCs review identified that the Reactor Coolant System (RCS) Leakage performance indicator (PI) crossed the green-to-white threshold. This was the result of increased RCS leakage in the Unit 1 drywell from the March 2019 Cryofit coupling failure.

On August 20, 2019, we received notification from your staff of Brunswicks readiness for the NRC to conduct our supplemental inspection to review the actions taken to address the White PI. Accordingly, we plan to conduct the supplemental inspection September 23-27, 2019. The inspection team will be led by Ms. Gwynne Eatmon, Resident Inspector at North Anna Power Station. This inspection will be conducted in accordance with the supplemental inspection procedure, 95001, Response to Action Matrix Column 2 Inputs, issued August 24, 2016.

The objectives of the supplemental inspection are to evaluate and assure the root cause and contributing causes of individual significant performance issues are understood, to independently assess and assure that the extent of condition and extent of cause of signification individual performance issues are identified, to assure that the corrective actions taken to address and preclude repetition of significant performance issues are prompt and effective, and to assure that corrective plans direct prompt actions to effectivity address and preclude repetition of significant performance issues.

On August 27, 2019, Ms. Eatmon discussed with Mr. Tom Sherrill some details and expectations for the one-week onsite inspection.

The enclosure lists documents that will be needed prior to the inspection. Please have the referenced information available no later than September 16, 2019, unless otherwise requested in the enclosure. The inspectors will try to minimize your administrative burden by specifically identifying only those documents required for inspection preparation.

W. Gideon 2

If additional documents are needed, they will be requested when identified. Prior to the onsite inspection, Ms. Eatmon 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; access to licensee computers; working space; arrangements for site access; and other applicable information.

Thank you for your cooperation in this matter. If you have any questions regarding the information requested or the inspection, please contact Ms. Eatmon at (404) 997-5190.

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

Sincerely,
