The licensee identified a finding of very … The licensee identified a finding of very low safety significance (Green) and associated NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings. This regulation requires in part that activities affecting quality be prescribed by procedures of a type appropriate to the circumstances and be accomplished in accordance with these procedures. Contrary to the above, the licensee identified during the performance of operator rounds on May 11, 2012, that a scaffolding modification interfered with the operation of the EDG G-01 ventilation gravity louvers contrary to the requirements of procedure MI 32.9, Scaffolding Program. The cause of the issue was determined to be the result of the related procedure not requiring an operations department review of modifications made to scaffolding after initial installation. The licensee entered this into the CAP as AR01795985 and AR01766629 and implemented corrective actions to remove the interference and modify the inadequate procedure. The performance deficiency was determined to be more than minor because it was associated with the Mitigating Systems Cornerstone attribute of equipment performance and adversely affected the associated cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the erected scaffolding impacted the EDG G-01 ventilation gravity louvers operation impacting the EDGs operability. The inspectors evaluated the issue using IMC 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, Tables 2 and 3, dated June 19, 2012, and IMC 0609, Appendix A, Exhibit 2, for the Mitigating System Cornerstone and answered No to the mitigating SSCs and functionality questions; therefore, the issue screened as very low safety significance (Green).d as very low safety significance (Green). +
