| Title | Failure to Identify and Correct an Open and Degraded Missile Shield Door (1R05.1) |
| Description | The inspectors identified a Non-Cited Violation (NCV) of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, for failure to identify and correct the west side entrance door of the 2B diesel fuel oil storage tank (DFOST) building that was unable to be closed due to a rusted latching mechanism and hinge assembly. The licensee entered the finding in their corrective action program (CAP) for resolution as condition report (CR) 2008-24914. The finding is greater than minor because it involved the protection against external factors performance attribute of the Mitigating System Cornerstone and affected the objective of ensuring that missile shield equipment is available and capable to prevent damage to mitigating systems. Significance Determination Process (SDP) Phase 1 Screening indicated that the finding is potentially risk significant due to an external event initiator and therefore, a Phase 3 analysis was required. The finding was determined to be of very low safety significance because of the low probability of a strong tornado impacting the region along with the unlikelihood the DFOST would be struck by a generated missile due to its location relative to the subject missile door. In addition, since the only one train of equipment was impacted for less than Technical Specifications (TS) allowed outage time, mitigating systems were available to allow successful core cooling in the event of a tornado. For these reasons, the Phase 3 analysis determined the risk associated with the finding to be Green. This finding was related to the identification of issues aspect of the CAP component in the problem identification and resolution crosscutting area (MC 0305 aspect P.1(a)). (Section 1R05 |
