SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Cooper Nuclear Station, 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
Cooper Nuclear Station began the inspection period in a scheduled refueling outage. The station performed a reactor startup on November 2, 2024, ending the outage. The unit reached rated thermal power on November 7, 2024. On November 8, 2024, the operators lowered power to 65 percent for a control rod sequence exchange. The unit returned to rated thermal power on November 9, 2024. On November 22, 2024, the operators lowered power to 80 percent for a control rod sequence exchange. The unit returned to rated thermal power on November 23, 2024. On December 15, 2024, the operators lowered power to 98 percent due to a feedwater flow instrumentation malfunction. The unit returned to rated thermal power on December 19, 2024. The unit remained at 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.
