During the facility-administered annual operating tests of licensed operators, the licensee training staff evaluated crew and individual operator performance during dynamic simulator scenarios and individual operator performance during job performance measures. There were two crew failures and 11 individual failures. The licensee remediated and retested the staff prior to returning them to licensed duties. Analysis. In accordance with Inspection Procedure 71111.11, each of the following was a performance deficiency against expected licensed operator knowledge and abilities: 1) Greater than 20 percent of the crews failing their scenarios and 2) greater than 20 percent of the licensed operator staff failing their operating tests. Using the Inspection Manual Chapter 0612, Appendix B, "Issue Screening," the inspecton determined that the finding was more than minor because the performance deficiency was associated with the Mitigating Systems Cornerstone attribute of human performance, and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspector determined that this finding could be evaluated using Inspection Manual Chapter 0609, Appendix I, "Licensed Operator Requalification Significance Determination Process." This finding was of very low safety significance (Green) because the finding was related to the requalification
I'd like to know how they come up with the 40% failure is unsafe?exam results, did not result in a failure rate of greater than 40 percent, and the licensed operators were remediated prior to returning to shift. This finding has a cross-cutting aspect in the area of human performance associated with
Green. The inspector reviewed a self-revealing finding associated with licensed operatorperformance on the annual requalification operating tests. Specifically, 2 of 8 crews (25 percent) failed the simulator scenario portion of the operating test; and 11 of 46 licensed operators (23 percent) either failed the scenario or failed the job performance measure portions of the operating tests. The licensee remediated and retested the staff prior to returning them to licensed duties. Wolf Creek entered this finding into their corrective action program as Condition Report 75336.
