| Title | Failure to Maintain Accurate EAL Thresholds |
| Description | An apparent violation of 10 CFR 50.54(q) was identified involving the failure to maintain a standard emergency action level scheme in September 2000 and November 2010 in accordance with the requirements of 10 CFR 50.47(b)(4). The licensee inappropriately calculated and changed Site Area Emergency and General Emergency radiation monitor threshold values on EAL (Emergency Action Levels) Table 3, Effluent Monitor Classification Thresholds. These changes adversely affected the ability of the licensee to properly classify events involving a radiological release. The inspectors determined the licensees inaccurate calculation of Site Area Emergency and General Emergency radiation monitor thresholds in September 2000 and November 2010 were performance deficiencies within the licensees control. This finding is more than minor because it was associated with the procedure quality and emergency response organization performance cornerstone attributes. This finding was evaluated using the Emergency Preparedness Significance Determination Process and was preliminarily determined to be of low to moderate safety significance (White) because it was a degraded risk significant planning standard function. The planning standard function was degraded because Columbia Generating Station would have been delayed in recognizing Site Area Emergencies and General Emergencies because of the inaccurate reactor building stack monitor EAL Table 3 values. This finding was entered into the licensees corrective action system as Action Requests AR00244316, AR00244578, and AR00244838 |
