| Title | Failure to Declare an Unusual Event |
| Description | The inspectors identified a non-cited violation of 10 CFR 50.54(q) for the failure of operations personnel to implement the emergency plan in response to a certain emergent event. Specifically, on November 6, 2013, after the hydraulic reservoir for main steam isolation valve 170 exploded during a nitrogen pre-charge pressure check, plant operators did not declare an Unusual Event as required by the emergency plan. The licensee entered the issue into the corrective action program as Action Request 4522120 and initiated an apparent cause evaluation to identify the cause and corrective actions. The failure to implement the emergency plan and declare an Unusual Event is a performance deficiency. The performance deficiency is more than minor, and therefore is a finding, because not classifying an event potentially puts the public at risk and affected the Emergency Preparedness Cornerstone attribute of emergency response organization performance. The inspectors evaluated the finding using Manual Chapter 0609, Appendix B, Emergency Preparedness Significance Determination Process, and determined to be of very low safety significance (Green). This finding was entered into the licensees corrective action program as Action Request 4522120. This finding has a crosscutting aspect in the area of human performance associated with the aspect of consistent process, because the licensee did not use a consistent, systematic approach to make decisions [H.13]. |
