The inspectors identified a non-citied vio … The inspectors identified a non-citied violation of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, because the licensee failed to properly install seismically qualified scaffolds adjacent to safety-related equipment as required by site procedures. Specifically, the licensees Scaffolding Guidelines procedure requires that scaffold builds not be erected in contact with plant equipment. Contrary to this requirement, the inspectors identified several instances where erected scaffolds were in contact with safety-related equipment. For corrective actions, the licensee completed a walk down of all erected scaffolds installed on site, briefed scaffold crews on equipment clearance requirements, are revising the Scaffolding Guidelines procedure to include increased supervisory oversight and separation gap requirements, and entered the condition into the CAP. The inspectors determined that failure to properly implement the scaffolding procedure was a licensee performance deficiency that warranted a significance determination. The performance deficiency adversely impacted the Mitigating Systems cornerstone and its objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The issue affected the protection against external factors attribute for this cornerstone. Specifically, several scaffolds were erected in contact with safety-related equipment which could challenge the availability, reliability and capability of safety-related systems affected during a seismic event. The inspectors determined the finding was not of more than very low safety significance (Green) using Exhibit 2 of IMC 0609, Appendix A, because the finding did not involve the loss or degradation of equipment or function specifically designed to mitigate a seismic event. The inspectors concluded that this finding was associated with a cross-cutting aspect in the work practice component of the human performance cross-cutting area. Specifically, contractor oversight and operations supervision did not provide effective oversight to prevent scaffold contact with safety-related equipment.old contact with safety-related equipment.
