At 1613 CST on November 17, 2025, it was discovered that the single train of high pressure coolant injection (HPCI) was inoperable. Due to this inoperability, the system was in a condition that could have prevented the fulfillment of a safety function; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(D). The isolation condenser was operable during this time period. There was no impact to the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified. The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance: A fuse in the turbine stop valve circuit blew during initial system testing for unit startup. |
