| Title | Failure to Maintain a Standard Emergency Action Level Scheme |
| Description | A licensee identified finding and associated Apparent Violation (AV) of 10 CFR 50.54(q) and 10 CFR 50.47(b)(4) was identified for the failure to follow and maintain in effect emergency plans which use a standard emergency classification and action level scheme. Specifically, the licensee\\\'s emergency plan Alert emergency action levels (EALs) RA1.1 and RA1.2 specified instrument threshold values that were beyond the indicated ranges of the effluent radiation monitors. The performance deficiency was determined to be more than minor because the deficiency, if left uncorrected, would have the potential to lead to a more significant safety concern. Specifically, in the event of a radiological emergency, the deficiency could lead to the failure to declare two Alert conditions in a timely manner. The finding was evaluated using the SDP in accordance with IMC 0609, \\\"Significance Determination Process,\\\" Appendix B. Using the \\\"Failure to Comply\\\" flowchart, the performance deficiency screened as a risk significant planning standard problem. The inspector determined the problem was a degraded function, rather than function failure, because even though the two Alerts (RA1.1 and RA1.2) would not be able to be declared due to the EAL threshold values being beyond the range of the associated instruments, an Alert could be declared, although in a delayed manner, using RA1.3 which is based on a sample results. The degraded risk significant planning standard function resulted in a preliminary White finding |
