| Title | Annual Operating Tests are not Comprehensive |
| Description | The inspectors identified an NCV of 10 CFR Part 55.59(aX2Xii) for Constellation\'s failure to administer annual operating tests to licensed operators to accomplish a comprehensive sample of items specified by 10 CFR Part 55.45(a)(7)&(8). Specifically, for the past five years, Constellation\'s annual operating tests have not evaluated licensed operators on important tasks that would be performed inside the auxiliary building. Constellation entered this issue into their CAP to evaluate corrective actions. This finding is more than minor because if left uncorrected, it would have the potential to lead to a more significant safety concern. This finding is associated with human performance attribute of the mitigating systems cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, Constellation\'s annual operating tests have not evaluated licensed operators on mitigation tasks that would be performed inside the auxiliary building. The finding is of very low safety significance according to IMC 0609, SDP, Appendix l, Licensed Operator Requalification SDP, because The issue was related to operating test quality. The inspectors determined that this finding had a cross-cutting aspect in the area of human performance, decision making, because Constellation did not use conservative assumptions in decision making that resulted in the development and administration of annual operating tests over the past five years that were not comprehensive (H.1 .b ) |
