| Title | Licensee-Identified Violation |
| Description | On March 6, 2015, Susquehanna identified a programmatic deficiency associated with the perimeter radiation monitoring system (RMS), which consists of 16 fixed radiation monitors at the site boundary that are activated and monitored by TSC/EOF staff, in that it was in a condition that could impact the ability to assess the EAL thresholds. Specifically, Susquehanna identified that the RMS is not maintained as required by EP-115, Equipment Important to Emergency Response, Revision 2, in that 4 of the 16 fixed radiation monitors in the RMS had been out of service since 2013 and the software that displays the RMS does not consistently run in computers in the EOF and TSC. 10 CFR Part 50.54(q) requires that the facility licensee follow and maintain in effect emergency plans which meet the standards in 10 CFR 50.47(b). 10 CFR 50.47(b)(4) requires, in part, that emergency response plans include a standard emergency classification and action level scheme, the bases of which include facility system and effluent parameters. Susquehannas Emergency Plan identifies the RMS as an initiating condition for EALs RG1 and RS1. Specifically, the two thresholds are met if sustained readings on the RMS are above the specified threshold value for greater than 15 minutes. Contrary to the above, the RMS was not maintained as required by the Emergency Plan which could have impacted the ability of Susquehanna to declare an emergency event. Susquehanna entered this issue into the CAP as CR-2015-06706. The inspectors determined that the finding was more than minor because it was associated with the facilities and equipment attribute of the Emergency Preparedness cornerstone and adversely affected the cornerstone objective to ensure that the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. The inspectors determined, through a review of IMC 0609, Appendix B, Emergency Preparedness Significance Determination Process, issued September 23, 2014, the finding to be of very low safety significance (Green), because redundant EAL initiating conditions associated with offsite dose assessment would have ensured that Susquehanna maintained a capability to declare the site area and general emergencies affected by the RMS. |
