Title | Untimely Declaration of Notice of Unusual Event |
Description | The inspectors identified an NCV of 10 CFR Part 50.47(b)(4) for the failure to implement the emergency classification and action level scheme in a timely manner during an actual event. Specifically, on July 4, 2010, phone communications to St. Mary\'s County were lost which met the conditions requiring declaration of a Notice of Unusual Event (NOUE). However, Constellation did not declare the NOUE in a timely manner. Five hours after the phone communications were lost, Constellation determined that conditions met the declaration criteria for an NOUE. Prior to classifying the event, the phone lines were restored. The off-site phone lines are part of the site\'s communications system that provide means for prompt notification of local, State, and Federal officials of events that may require urgent actions. Constellation entered this issue into their corrective action program (CAP) for resolution. Immediate corrective action included establishing a standing order to provide operators guidance in the event of a loss of communications. The finding is greater than minor because it is associated with the Emergency Preparedness (EP) cornerstone attribute of emergency response organization performance (actual event response) and it adversely affects the cornerstone objective to ensure that Constellation was capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. The inspectors determined that the finding is of very low safety significance in that it was associated with an actual event where the operators failed to declare an NOUE in a timely manner during a complete loss of communications to one off-site agency. This finding has a cross-cutting aspect in the area of human performance, decision making, because Constellation did not make a safety significant decision using a systematic process to declare the NOUE in a timely manner. Specifically, Constellation did not use a systematic process such as a standing order or procedure to provide guidance to operators to address a loss of communications. In addition, Constellation did not adequately implement emergency response organization\'s (ERO) roles and authorities as designed to obtain interdisciplinary input on safety significance decisions such as event classification (H.1.a of IMe 0310). |
