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.
* * * UPDATE ON 5/17/2009 AT 0552 FROM MICHAEL REED TO MARK ABRAMOVITZ * * *
The failure was on HCU 22-11 not 22-15.
The licensee notified the NRC Resident Inspector. Notified the R1DO (Holody) via e-mail.

"On 5/17/09, at 0335, Hope Creek automatically scrammed due to low Reactor Pressure Vessel water level approximately two seconds prior to locking the Reactor Mode Switch in Shutdown 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 22-11. A manual scram was reinserted at 0445 to mitigate the air leak."
The licensee notified the NRC Resident Inspector. Notified the R1DO(Dentel).

TECHNICAL SUPPORT CENTER OUT OF SERVICE DUE LOSS OF EMERGENCY DIESEL GENERATOR
"A condition is being reported per Technical Requirements Manual 13.13.1 Emergency Response Facilities Required Action B.2. The Functionality of the Technical Support Center (TSC) has been lost due to failure of the Backup Diesel Generator (which provides backup power to TSC related equipment) to pass a required surveillance. Alternate facilities are available to provide emergency response functions and actions are proceeding to return the TSC to FUNCTIONAL status with high priority. The NRC Resident Inspector Tim Chandler has been notified."
* * * UPDATE ON 5/19/09 AT 1615 FROM ROBERT ROWLAND TO VINCE KLCO * * *
At 1559 the Backup Diesel Generator was declared operable.
The licensee will notify the NRC Resident Inspector. Notified the R2DO (Henson).
