| Title | Inadequate Corrective Actions for Bay Water Level EAL Entry Criteria |
| Description | \"The inspectors identified a Green NCV of 10 CFR 50.54(q), for Constellation
failure to maintain the Emergency Plan to adequately meet the standards in 50.47(b) Specifically, Constellation failed to correct a condition related to not having a clea method to assess and determine the bay water level emergency action level (EAL) entr criteria for an Unusual Event (UE). Constellations initial compensatory and correctiv actions were inadequate because the compensatory action did not reflect the actua global bay conditions, thereby preventing operators from correctly implementing th EAL; and the proposed corrective action, although not implemented, would hav resulted in a decrease in effectiveness of the emergency plan. The immediate correctiv actions included revising the compensatory measures to ensure that operators measur the bay water level at the appropriate location (i.e., in front of the trash racks). Th planned corrective actions included installing a bay level monitoring system The inspectors determined that this finding was more than minor because it wa associated with the facilities and equipment attribute of the Emergency Preparednes cornerstone and it affected the cornerstone objective of ensuring that a licensee i capable of implementing adequate measures to protect the health and safety of th public in the event of a radiological emergency. Specifically, inadequate monitoring o intake bay level could have resulted in failure to declare a UE. The inspectors reviewe the EAL entry criteria and determined that this performance deficiency did not affec Constellations ability to declare any event higher than a UE. The inspectors evaluate this finding using IMC 0609, Appendix B, Emergency Preparedness Significanc Determination Process, Sheet 1, Failure to Comply. Since the declaration of a U based on low bay level could have been missed or delayed, this finding was considere consistent with the example provided and was therefore determined to be of very lo safety significance. This finding had a cross-cutting aspect in the area of proble identification and resolution because Constellation did not take appropriate correctiv action to address this safety issue in a timely manner, commensurate with its safet significance and complexity.
