SUBJECT:

ANNUAL ASSESSMENT LETTER FOR DAVIS-BESSE NUCLEAR POWER STATION, UNIT 1 (REPORT 05000346/2022006)

Dear Terry Brown:

The NRC has completed its end-of-cycle performance assessment of Davis-Besse Nuclear Power Station, Unit 1, reviewing performance indicators (PIs), inspection results, and enforcement actions from January 1, 2022, through December 31, 2022. This letter informs you of the NRCs assessment of your facility during this period and its plans for future inspections at your facility. The NRC concluded that overall performance at your facility preserved public health and safety. The baseline inspection program was completed at your facility as defined in Inspection Manual Chapter 2515, Light-Water Reactor Inspection Program - Operations Phase.

The NRC determined the performance at Davis-Besse Nuclear Power Station, Unit 1, during the most recent quarter was within the Regulatory Response Column, the second highest performance column of the NRCs Reactor Oversight Process (ROP) Action Matrix. This conclusion was based on one or more greater-than-Green inspection findings (or PIs) in the Security cornerstone, originating in the third quarter of 2021 (ML22031A171).

On May 6, 2022, your staff notified the NRC of your readiness for the supplemental inspection to review the actions taken to address the performance issues. On July 6, 2022, the NRC notified you of plans to conduct a supplemental inspection in accordance with Inspection Procedure (IP) 95001, Supplemental Inspection for One or Two White Inputs in a Strategic Performance Area, and on August 23, 2022, the NRC conducted the entrance meeting.

However, on October 4, 2022, the NRC issued a supplemental inspection interim report (ML22276A215), which stated that the NRC inspection team determined that it could not satisfactorily complete the objectives per the inspection procedures, and the inspection was suspended. The NRC plans to resume the supplemental inspection when your staff has notified the NRC of your readiness. In addition, a single inspection finding having low-to-moderate safety significance (i.e., White) in the Mitigating Systems cornerstone was closed during this assessment period. This finding originated in the fourth quarter of 2021 (ML21356A058) and was related to your failure to install emergency diesel generator parts that were suitable to the application. An IP 95001 supplemental inspection was completed satisfactory, and the finding was closed in third quarter of 2022 (ML22314A225).

Although plant performance was within the Regulatory Response Column, the NRC has not yet finalized the characterization of Apparent Violation (AV)05000346/2022091-01, Apparent Violation of 10 CFR 50.54(i) (ML23025A407). This apparent violation is associated with the failure of the facility licensee to ensure that an individual operating the controls of the facility meets all conditions of the license as required in 10 CFR Part 50.54(i) and provided in 10 CFR Parts 55.53 and 55.59. The final determination may affect the enclosed inspection plan.

The enclosed inspection plan lists the inspections scheduled through December 31, 2024.

The NRC provides the inspection plan to allow for the resolution of any scheduling conflicts and personnel availability issues. Routine inspections performed by resident inspectors are not included in the inspection plan. The inspections listed during the last twelve months of the inspection plan are tentative and may be revised. The NRC will contact you as soon as possible to discuss changes to the inspection plan should circumstances warrant any changes.

In response to the COVID-19 public health emergency (PHE), the NRC adjusted inspection plans and schedules to safeguard the health and safety of both NRC and licensee staff while still effectively implementing the ROP. While the PHE continues, overall conditions throughout the country support performance of our inspection and oversight activities returning to normal onsite presence by our resident and region-based inspectors and completion of nominal baseline inspection samples. We continue to monitor site-specific conditions and, as discussed in our November 2, 2021, memo, Implementation of Inspection Programs Following Re-Entry from the Public Health Emergency for the Reactor Safety Program (ML21295A302), it may be necessary to alter how and when we perform our inspection and oversight activities as we balance the importance of protecting the health and safety of our staff with the need to conduct effective oversight that supports the NRCs critical safety mission.

For inspections requiring extensive coordination with offsite organizations, such as evaluated emergency preparedness exercises, NRC guidance and frequently asked questions for security and emergency preparedness can be found here: https://www.nrc.gov/about-nrc/covid-19/security-ep/. Similarly, the NRC has developed guidance if force-on-force inspections cannot be completed as scheduled due to an emergency, such as the COVID-19 PHE. These changes help ensure the health and safety of both NRC and licensee staff while maintaining the NRCs important safety and security mission during the COVID-19 PHE. The attached inspection plan is accurate on the date of issuance but remains subject to change based on approval of potential exemption requests or other changes needed due to changing conditions in the COVID-19 PHE. NRC staff will contact your appropriate regulatory affairs staff in order to coordinate inspection planning and scheduling. Beginning on January 1, 2023, the engineering inspection frequency will transition from a triennial (3-year) to a quadrennial (4-year) cycle. The new engineering inspection program will consist of a Comprehensive Engineering Team Inspection (CETI)1 and three Focused Engineering Inspections (FEIs) that will be performed in each quadrennial cycle. For the cycle beginning in 2023, the FEIs will be: Fire Protection Team Inspection, Commercial Grade Dedication and an engineering inspection that reviews age-related degradation and management2.

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).

Please contact Billy C. Dickson at 630-829-9827 with any questions you have regarding this letter.

Sincerely, Julio F. Lara, Director Division of Operating Reactor Safety Docket Nos. 05000346 and 07200014 License No. NPF-3 Enclosure:

Inspection Plan cc: Distribution via LISTSERV 1 Aspects of the Design Basis Assurance Inspection (DBAI), Evaluations of Changes, Tests, & Experiments, and Heat Sink inspections will be included in the new CETI inspection. Previously scheduled Evaluation of Changes, Tests, & Experiments and Heat Sink inspections have been cancelled and removed from attached Report 22.

2 The Age-Related Degradation procedure is publicly available, and the NRC plans to implement the first inspection of this type beginning in July 2023.

Signed by Lara, Julio on 03/01/23
