Title | Licensee-Identified Violation |
Description | Title 10 CFR 50.54(q)(2) requires a licensee to follow and maintain in effect an emergency plan that meets the requirements of 10 CFR 50.47(b). Planning standard 10 CFR 50.47(b)(4) requires a licensee have a standard emergency action level scheme. Licensee procedure 13.1.1, Classifying the Emergency, Revision 47, implements the licensees standard emergency action level scheme. Emergency action levels 5.1.U.1 and 5.1.A.1 require classification of an emergency based, in part, on a valid reading exists which exceeds the Table 3 unusual event or alert effluent monitor thresholds for plant service water radiation indicting switch TSW-RIS-5. Contrary to the above, between April 3, 2015 and April 25, 2015, the licensee did not follow an emergency plan meeting the requirements of 10 CFR 50.47(b)(4). Specifically, the licensee ability to classify emergency action levels 5.1.U.1 and 5.1.A.1 was degraded because the modify select parameter was set incorrectly for TSW-RIS-5 resulting in an unintended attenuation factor of 15. This finding was identified by the licensee and entered in the licensees corrective action program as Action Request AR 326313. This finding was determined to be of very low safety significance because it did not involve Emergency Action Levels greater than Alert per Table 5.4-1 of Inspection Manual Chapter 0609 Appendix B, Emergency Preparedness Significance Determination Process. |
