The inspectors identified a finding of very low safety significance and associated non-cited violation of
10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure on September 11, 2014, to develop and supply specific minimum clearance requirements to maintenance staff prior to erecting scaffold in close proximity to safety-related equipment. The licensee has entered this item into its corrective action program (
CAP). The performance deficiency was determined to be more than minor because, if left uncorrected, the performance deficiency has the potential to become a more significant safety concern. Specifically, the method used to determine the minimum clearances did not account for the potential motion of in-place systems/components. The inspectors determined the finding could be evaluated in accordance with
IMC 0609,
Significance Determination Process, Exhibit 2, Mitigating System Screening Questions, dated June 2, 2011. The finding was determined to be of very low safety significance (Green). This finding has a cross-cutting aspect in the area of Human Performance, Training, because the licensee did not provide training and ensure knowledge transfer to maintain a knowledgeable, technically competent workforce and instill nuclear safety values.
