| Title | Secondary Containment Integrity Momentarily Declared Inoperable |
| Event Description | Station personnel simultaneously opened the inner and outer air lock doors from the reactor building to the reactor control enclosure (Reactor Building 23 foot elevation North West airlock). Reactor Building secondary containment integrity was declared INOPERABLE per TS 3.5.B.2 due to both containment airlock doors being momentarily open at the same time. Reactor Building D/P (differential pressure) remained less than negative 0.25 inches water column.
Reactor Building secondary containment integrity was declared OPERABLE following verification that at least one airlock door to each access of secondary containment was closed per TS 3.5.B.2. Total LCO time was approximately 10 seconds. The NRC Resident Inspector has been informed. |
