SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at James A. FitzPatrick Nuclear Power Plant, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.
List of Findings and Violations
No findings or violations of more than minor significance were identified.
Additional Tracking Items
None.
PLANT STATUS
FitzPatrick began the inspection period operating at rated thermal power. On November 7, 2025, operators reduced reactor power to 74 percent to perform turbine valve testing and a control rod pattern adjustment. Operators raised reactor power to rated thermal power the next day. FitzPatrick remained at, or near, rated thermal power for the remainder of the 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 activities described in IMC 2515, Appendix D, Plant Status, observed risk significant activities, and completed on-site portions of IPs. 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.

71152S - Semiannual Trend Problem Identification and Resolution
Semiannual Trend Review (Section 03.02) (1 Sample)
- (1) The inspectors reviewed the FitzPatrick corrective action program to identify potential trends that might be indicative of a more significant safety issue.
INSPECTION RESULTS
Observation: Semiannual Trend Review 71152S The inspectors evaluated a sample of issues and events that occurred over the third and fourth quarters of 2025 to determine whether issues were appropriately considered as emerging or adverse trends. The inspectors verified issues were appropriately evaluated by Constellation staff for potential trends and addressed within the scope of the corrective action program or through department review. The inspectors did not identify any new trends that could indicate a more significant safety issue. The inspectors determined that Constellation personnel identified trend issues at a low threshold and entered them into the corrective action program for resolution.
The inspectors noted licensee-identified trends in rework evaluation efficiency and engineering technical human performance issues. The inspectors independently evaluated these trends for significance in accordance with the guidance in IMC 0612, Appendix B, "Issue Screening," and Appendix E, "Examples of Minor Issues." The inspectors determined that none of the conditions were deficiencies of greater than minor significance and, therefore, are not subject to enforcement action in accordance with the NRC's Enforcement Policy.

The inspectors verified that no proprietary information was retained or documented in this report.
- On January 22, 2026, the inspectors presented the integrated inspection results to Alex Sterio, Site Vice President, and other members of the licensee staff.
- On December 15, 2025, the inspectors presented the radiation safety inspection results to Garrick Olson, Plant Manager, and other members of the licensee staff.
