Dear Mr. Stoddard:

On June 30, 2021, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at North Anna Power Station. On July 15, 2021, the NRC inspectors discussed the results of this inspection with Fred Mladen and other members of your staff. The results of this inspection are documented in the enclosed report.

One Severity Level IV violation without an associated finding is documented in this report. We are treating this violation as a non-cited violation (NCV) consistent with Section 2.3.2 of the Enforcement Policy.

No NRC-identified or self-revealing findings were identified during this inspection.

If you contest the violation or the significance or severity of the violation documented in this inspection report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN:

Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement; and the NRC Resident Inspector at North Anna Power Station. 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 Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding.

PLANT STATUS

Unit 1 began the inspection period shutdown for refueling outage 1R28. The unit was restarted on April 22, 2021, and the turbine generator was synchronized to the grid on April 24, 2021.

The unit was returned to operating at or near rated thermal power on April 27, 2021. On May 6, 2021, the unit was shut down due to degrading condenser vacuum as a result of a leak inside the main condenser. The leak was repaired, and the unit was restarted on May 17, 2021.

The turbine generator was synchronized to the grid on May 17, 2021, and the unit was returned to operating at or near rated thermal power on May 19, 2021, where it remained through the end of the inspection period.

Unit 2 operated at or near 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 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.

Starting on March 20, 2020, in response to the National Emergency declared by the President of the United States on the public health risks of the coronavirus (COVID-19), resident and regional inspectors were directed to begin telework and to remotely access licensee information using available technology. During this time, the resident inspectors performed periodic site visits each week, increasing the amount of time on site as local COVID-19 conditions permitted.

As part of their onsite activities, resident inspectors conducted plant status activities as described in IMC 2515, Appendix D; observed risk significant activities; and completed on site portions of IPs. In addition, resident and regional baseline inspections were evaluated to determine if all or a portion of the objectives and requirements stated in the IP could be performed remotely. If the inspections could be performed remotely, they were conducted per the applicable IP. In some cases, portions of an IP were completed remotely and on site. The inspections documented below met the objectives and requirements for completion of the IP.

INSPECTION RESULTS

RCS Pressure Boundary Leakage Results in Condition Prohibited by Technical Specifications Cornerstone Severity Cross-Cutting Aspect Report Section Not Applicable Severity Level IV NCV 05000339/2021002-01 Open/Closed Not Applicable 71153 A self-revealed SL IV non-cited violation (NCV) of Technical Specification (TS) 3.4.13, RCS Operational Leakage and TS 3.4.4, RCS Loops - Mode 1 and 2 was identified for reactor coolant system pressure boundary leakage due to a cracked weld on the reactor coolant pump (RCP) seal injection piping for longer than the allowed completion time.

Description:

On April 6, 2020, at 0037, the station identified an increase in the unidentified leak rate as part of their normal monitoring, and entered licensee procedure 2-AP-16, Increasing Primary Plant Leakage due to an increase in unidentified leakage from 0.0247 gallons per minute (gpm) to 0.1081 gpm. At that time, the station immediately began taking appropriate actions to identify the source of the unidentified leakage. On April 9, 2020, at 0100, the station identified that a weld on the A RCP seal injection piping to the thermal barrier was leaking, which was defined as pressure boundary leakage, and was prohibited by TS 3.4.13. The station then began a controlled shutdown in accordance with the TS action statement to be in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and Mode 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

The licensee submitted licensee event report 05000339-2020-001-00.

Corrective Actions: The licensee repaired the weld by grinding out the defect and completing a repair weld. The station also implemented a non-destructive examination program on the similar welds for both North Anna Units 1 and 2, to be used until the welds are modified permanently.

Corrective Action References: CR1144530

Performance Assessment:

The NRC determined this violation was not reasonably foreseeable and preventable by the licensee and therefore is not a performance deficiency.

Specifically, the equipment failure could not have been avoided or detected by the licensees quality assurance program or other related control measures. The weld in question was original from the equipment manufacturer, and had been in service for nearly 40 years. The station took prompt and reasonable actions to identify the location of the unidentified leakage and shut down within the required limiting condition for operation (LCO) completion time after identification.

Enforcement:

Reactor violations without a performance deficiency are dispositioned using the traditional enforcement process. Specifically, Enforcement Policy Section 2.2.4 states, in part, that violations dispositioned using traditional enforcement includesviolations not associated with ROP findings.

Severity: The inspectors reviewed Section 6.1.d.1 of the Enforcement Policy and determined this violation was characterized as a Severity Level IV because it was a failure to comply with a TS-required action for an LCO in Section 3.0.

Violation: North Anna Power Station, Unit 2 TS Subsection 3.4.13, RCS Operational Leakage, Condition B requires, in part, that if pressure boundary leakage exists, the unit must be in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and Mode 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. Additionally, TS Subsection 3.4.4, RCS Loops - Modes 1 and 2, requires that the unit must be in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> if there are not three operable RCS loops. Contrary to the above, between April 6, and April 9, 2020, three RCS loops were not operable due to pressure boundary leakage, and the unit was not placed in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> or Mode 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Enforcement Action: This violation is being treated as a NCV, consistent with Section 2.3.2 of the Enforcement Policy.
