Dear Mr. Stoddard:

On December 31, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your North Anna Power Station, Units 1 and 2. On January 24, 2019, the NRC inspectors discussed the results of this inspection with Ms. L. Hilbert and other members of your staff. Inspectors documented the results of this inspection in the enclosed inspection report.

NRC inspectors did not identify any finding or violation of more than minor significance. 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,

/RA/

Unit 1 operated at or near 100 percent rated thermal power for the entire inspection period.

Unit 2 operated at or near 100 percent rated thermal power for the entire inspection period.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed plant status activities described in IMC 2515, Appendix D, Plant Status, and conducted routine reviews using IP 71152, Problem Identification and Resolution. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

OTHER ACTIVITIES

- TEMPORARY INSTRUCTIONS, INFREQUENT AND ABNORMAL 60853 - Onsite Fabrication of Components and Construction of an Independent Spent Fuel Storage Installation The inspectors conducted a review of licensee and vendor activities in preparation for the concrete placement of the independent spent fuel storage installation (ISFSI) Pad #3. The licensee will use the Transnuclear Inc. Standardized NUHOMS Horizontal Modular Storage System. The inspectors walked down the construction area of the ISFSI pad and examined the rebar installation for compliance to licensee-approved drawings, specifications, procedures, and applicable codes, the Certificate of Compliance, and technical specifications. The inspectors also evaluated the concrete formwork installation for compliance to the licensee-approved drawings. The inspectors interviewed licensee and contract personnel to verify knowledge of the planned work. When the 7-day and 28-day compression tests were completed by the independent laboratory, the inspectors reviewed the results to verify that the acceptance criteria were met. The inspectors noted that all tested samples satisfied the acceptance criteria.

INSPECTION RESULTS

Observation 71153 - Follow-up of Events and Notices of Enforcement Discretion The inspectors determined that the LER was accurate. The licensees corrective action to install animal guards while replacing the RSST was appropriate. A RSST was completed Fall 2018 through DC NA-13-01190, B RSST will be implemented Fall 2019 through DC NA-13-01190, and C RSST will be implemented Summer 2019 through DC NA-16-01034. The inspectors concluded that it was not reasonable to foresee or correct the cause discussed in the LER, therefore no performance deficiency was identified. The inspectors also concluded that no violation of NRC requirements occurred. This LER is closed.

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

• On December 21, 2017, the inspector discussed the results of the ISFSI pad inspection with Mr. D. Taylor, North Anna Licensing Manager.

• On January 24, 2019, the inspector presented the quarterly integrated inspection report results to Ms. L. Hilbert, and other members of the licensee staff.
