INSPECTION RESULTS

Observation: Adverse trend in fire protection 71152S The inspectors reviewed the licensee's corrective action program (CAP) for trends associated with implementation of fire protection program controls and equipment during a six-month period ending on June 30, 2024. There were 80 condition reports reviewed with the trend code Fire Pro and involved programmatic issues from longstanding open fire impairments, delayed detector testing, housekeeping, spurious alarms, actual fire brigade response, and equipment issues. Nine of these were NRC identified issues and one (AR 2478849) was considered a green NCV documented in the first quarter 2024 inspection report. The licensee identified an adverse trend (AR 2475859) in January, in the amount of open fire impairments and has made progress in fixing the equipment issues and closing more than half of the identified impairments. The licensee has also documented an adverse trend (AR 2489315) in sporadic deluge actuation, and final corrective actions to mitigate the adverse trend were in development.

EXIT MEETINGS AND DEBRIEFS

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

• On July 16, 2024, the inspectors presented the integrated inspection results to Mr.

Carlos Santos, Organizational Effectiveness Site Director and other members of the licensee staff.
