| Title | Reactor Water Cleanup System Isolation Channel Inoperable |
| Event Description | The following information was provided by the licensee via email:
On May 16, 2024 at 0840 EDT, operations declared the reactor water cleanup (RWCU) leak detection instruments related to the high differential flow signal inoperable. Technical specification (TS) 3.3.6.1, primary containment and drywell isolation instrumentation, conditions `A and `B were entered as one required channel of instrumentation was inoperable, and an automatic function with isolation capability was not maintained. Therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(C) and 10 CFR 50.72(b)(3)(v)(D). All other RWCU primary containment isolation instrumentation functions remained operable. At 1210 EDT, the affected leak detection instruments were declared operable, and the TS limiting condition for operation 3.3.6.1 was declared met. There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified. |
