| Title | |
| Event Description | While shutdown in Mode 5, containment recirculation sump 'B' was inspected for sump screen bypass flow paths in accordance with the requirements of NRC Bulletin 2003-01. Inspection results showed that approximately 25 square inches of space is available for recirculation flow to bypass the sump screens. This condition has the possibility of affecting the containment spray, safety injection and residual heat removal systems. The plant is stable in a refueling outage at approximately 95 degrees F, with normal residual heat removal in service and loop levels at 72 inches.
The licensee notified the NRC Resident Inspector.
The licensee is retracting this event after performing an extensive evaluation had determined that equipment required to mitigate the event, though found to be in a degraded condition, would have performed their functions. This event has been discussed with the NRC Resident Inspector and he was informed of the event retraction. Notified Reg 1 RDO(Rogge) |
