SUBJECT:

ANNUAL ASSESSMENT LETTER FOR CALLAWAY PLANT (REPORT 05000483/2021006)

Dear Mr. Diya The U.S. Nuclear Regulatory Commission (NRC) has completed its end-of-cycle performance assessment of the Callaway Plant, reviewing performance indicators (PIs), inspection results, and enforcement actions from January 1, 2021 through December 31, 2021. 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 the Callaway Plant 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 a single White performance indicator in Unplanned Scrams per 7000 Critical Hours in the Initiating Events Cornerstone originating in the fourth quarter of 2020, and all Green inspection findings during the assessment period.

Therefore, in addition to ROP baseline inspections, the NRC plans to conduct a supplemental inspection in accordance with Inspection Procedure 95001, Supplemental Inspection Response to Action Matrix Column 2 Inputs due to exceeding the White threshold for the Unplanned Scrams per 7000 Critical Hours Performance Indicator. The objectives of this procedure are to assure that the root causes and contributing causes of individual and collective significant performance issues are understood, to independently assess and assure that the extent of condition and extent of cause of significant individual and collective performance issues are identified, to assure that corrective actions taken to address and preclude repetition of significant performance issues are prompt and effective, and to assure that corrective action plans direct prompt actions to effectively address and preclude repetition of significant performance issues.

F. Diya 2 In your letter dated January 3, 2022 (ML22003A179), the NRC was notified of your readiness for the supplemental inspection to review the actions taken to address the performance issues.

Therefore, the NRC has scheduled this supplemental inspection for the week of March 14, 2022.

The enclosed inspection plan lists the inspections scheduled through December 31, 2023.

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 in order 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 to return 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.

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).

F. Diya 3 Please contact Gregory E. Werner at (817) 200-1141 with any questions you have regarding this letter.

Sincerely,

/RA/
