| Title | Failure to Administer an NRC Annual Operating Test Simulator Scenario Re-examination That Met Procedural Requirements |
| Description | The inspectors identified a Green finding of Exelon procedure TQ-AA-150, Operator Training Programs, and TQ-AA-155, Conduct of Simulator Training and Evaluation, based on a determination that the minimum number of scenarios required for simulator re-examination was not administered following a crew failure of the dynamic simulator scenario portion of the annual operating exam during week two of the 2012 Licensed Operator Requalification Training (LORT) Annual Operating Test. Exelon staff entered this finding into their corrective action program (CAP) (IR 1437839), conducted a prompt investigation, assigned an action to complete the annual operating exam scenario set for the crew in question, and initiated an Apparent Cause Evaluation (ACE). The inspectors determined that the finding was more than minor because it was associated with the Human Performance attribute of the Mitigation Systems cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). The risk importance of this issue was evaluated using IMC 0609, Appendix I, Licensed Operator Requalification Significance Determination Process (SDP). Based on this screening criteria, the finding (inadequate retest) was characterized by the SDP as having very low safety significance (Green) because crew remediation was conducted and a partial re-evaluation performed. This finding had a cross-cutting aspect in the area of Human Performance, Work Practices, because Exelon did not ensure that personnel followed procedures H.4(b). Specifically, the simulator scenario re-exam administered following a failed Annual Operating Test did not meet procedure requirements for number of scenarios. |
