Event Text

MANUAL REACTOR SCRAM DUE TO LOSS OF SCRAM AIR HEADER

"At 0335, Hope Creek was manually scrammed due to indications of multiple control rods drifting. All rods indicate fully inserted. Reactor level is being controlled in the normal band with Start-up level control in automatic. Reactor pressure is being controlled by bypass valves to the main condenser. Recirc pumps are in service and no ECCS system actuations were reached. The failure is a solder joint on the air supply to HCU 22-15. A manual scram was reinserted at 0445 to mitigate the air leak."

The licensee reset the scram to re-pressurize the scram air header. Once the leak was located, a second manual scram signal was initiated to secure the leak.

No safety relief valves lifted during the transient. The electrical grid is stable and the plant is in a normal shutdown electrical lineup.

The licensee will be notifying the Lower Alloways Creek Township and has notified the NRC Resident Inspector.

The failure was on HCU 22-11 not 22-15.

The licensee notified the NRC Resident Inspector. Notified the R1DO (Holody) via e-mail.
