| Title | Failure to Adequately Maintain EALs |
| Description | The inspectors identified a Green NCV associated with emergency preparedness planning standard Title 10 of the Code of Federal Regulations (10 CFR) 50.47(b)(4) and the requirements of Sections IV.B and IV.C of Appendix E to 10 CFR 50. Specifically, Dominion did not maintain the Millstone Units 2 and 3 emergency action level (EAL) schemes for assessing a loss of forced flow cooling during refueling operations. Dominion entered this issue into the CAP and implemented temporary corrective actions which included procedure changes to direct operators to the shutdown safety assessment checklists to determine representative reactor coolant system (RCS) temperature increases in order to assess the initiating conditions (ICs) for this situation. The inspectors determined that the failure by Dominion to provide site specific criteria for operators to adequately implement the EALs for a loss of forced flow cooling during refueling was a performance deficiency that was reasonably within their ability to foresee and prevent. The finding is more than minor because it is associated with the Procedure Quality attribute of the Emergency Planning Cornerstone and affected the cornerstone objective to ensure that Dominion is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. In accordance with IMC 0609, Appendix B, Emergency Preparedness Significance Determination, the inspectors determined that this finding is of very low safety significance (Green) because the performance deficiency was an issue where two EAL ICs had been rendered ineffective such that an Unusual Event and an Alert would not be declared, or declared in a degraded manner for a loss of forced flow cooling during refueling. The finding has a cross-cutting aspect in the area of Problem Identification and Resolution, in that Dominion did not implement a CAP with a low threshold for identifying issues. Dominions self-assessment for two previous NCVs regarding EAL deficiencies failed to identify the lack of specific criteria to assess the ICs for EALs EU1.2 and EA2.1 for a loss of forced cooling flow during refueling. |
