The licensee declared a notice of unusual event as a result of a tsunami warning issued for the coastal areas of California. The tsunami warning is a result of a 8.9 magnitude earthquake off the coast of Japan. The licensee is in EAL HU1.5, 'Tsunami Affecting the Protected Area.' The NRC remains in the normal response mode.
The NRC Resident Inspector has been notified.
* * * UPDATE AT 1134 EST ON 3/11/2011 FROM MIKE QUITTER TO JOE O'HARA * * *
"A classification of unusual event was declared at 0123 PST on March 11, 2011 due to a tsunami warning issued by the NOAA for the California West Coast. Diablo Canyon Power Plant [DCPP] has implemented the requirements of Casualty Procedure M-5, 'Response to Tsunami Warning.' Plant personnel were evacuated from the DCPP intake structure at 0742 PST. Evacuation of personnel from the intake structure constitutes a deviation from DCPP license condition '2.E' and authorized pursuant to 10CFR50.54(x).
"No damage or injuries has been observed as a result of this tsunami event and there is no impact on the health and safety of the general public."
Notified the R4DO (Farnholtz), R4RA (Collins), IRD (Marshall), and NRR (Grobe).
* * * UPDATE AT 1843 EST ON 3/11/2011 FROM JOHN BECERRA TO MARK ABRAMOVITZ * * *
Diablo Canyon has terminated their Unusual Event at 1528 PST because the tsunami warning has been reduced to a tsunami advisory. No damage occurred during this event.

| Event Text MALFUNCTIONING VALVE LEADS TO A LOSS OF DEFENSE IN DEPTH
"During a performance of temporary operating procedure on a laser optical device, it was identified that one of two valves used to isolate the device failed to operate. The valves are operated as a pair and the valves are redundant to provide defense in depth. One valve shut as expected. The second valve did not shut.
"The valves are identified as an Item Relied on For Safety (IROFS). The system was not operating and one of the valves operated as designed. No unsafe condition existed.
"Operability of both valves is required to meet the performance requirements of 10CFR70.61.
"This event is being reported pursuant to the requirements of 10CFR70 Appendix A(b)(2) within 24 hours. The affected device will remain shutdown pending further investigation and implementation of associated corrective actions.
"[This event is of] low safety significance - the discovery did not result in an unsafe condition." | |
