| Title | Containment Leak Rate Greater than Tech Spec |
| Event Description | On May 8, 2018 at 0139 Central Daylight Time, Farley Nuclear Plant Unit 1 declared containment inoperable due to total containment leak rate greater than technical specifications. The 1B containment cooler had seat leakage of approximately 30 gallons per minute from a service water drain valve.
Though the containment cooler service water supply is not tested per the Appendix J program, a loss of the containment barrier is possible under accident conditions. The service water flow path to the 1B containment cooler has been isolated to exit the condition. The licensee will notify the NRC resident inspector. |
