Event Text
POWER OUTAGE CAUSING LOSS OF BATTERY ROOM VENTILLATION AND HYDROGEN MONITOR

"At approximately 1451 hours EDT on 07/1/2011, the Nuclear Regulatory Affairs Manager completed his review of the initial (draft) engineering report [related to an event that occurred on June 11, 2011].. [The review determined] the impact the June 11, 2011 power outage may have had on the Battery Room 3/4 forced air ventilation and hydrogen monitoring systems. [The review also] determined the incident should be reported to the NRC because he could find no evidence that either system would have met their respective IROFS [Item Relied On for Safety] surveillance requirements during the power outage.

"This incident is being reported to the Nuclear Regulatory Commission (NRC) as a 24-hour event in accordance with American Centrifuge Administrative Procedure ACD2-RG-044 (Nuclear Regulatory Event Reporting), Appendix B, Section I, which states: 'An event in which equipment is disabled or fails to function as designed as described by any of the following: (Paragraph) 2. The equipment is required to be available and operable when it is disabled or fails to function: AND no redundant equipment is available and operable to perform the required safety function .'"

The licensee will notify the NRC Region II office and site Department of Energy.
