| Title | Licensee-Identified Violation |
| Description | The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as a noncited violation. Title 10 CFR Part 50.73(a)(2)(v), required that the licensee submit a Licensee Event Report for safety system functional failures within 60 days. Contrary to this, the licensee failed to report the July 21, 2008 failure of both auxiliary building exhaust fans as a safety system functional failure within 60 days. On January 28, 2010, the licensee identified the failure to make the report during a review of past events. The licensee subsequently reported the condition as Licensee Event Report 05000323/2010-001-00, Diablo Canyon Power Plant Unit 2 Loss of Auxiliary Building Ventilation System Exhaust Fans. The inspectors concluded that the failure to make a required Licensee Event Report was a Severity Level IV violation using the General Statement of Policy and Procedure for NRC Enforcement Actions, Supplement I - Reactor Operations, dated January 14, 2005. Pacific Gas and Electric entered the issue into their corrective action program as Notifications 50265954 and 50301839 |
