A finding of very low safety significance and an associated
NCV of
10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified by the inspectors for the licensees failure to include criteria in procedures for evaluation of storage areas and storage racks built in the power block. Licensee procedure MOP11, Combustible Material, placed controls on the storages areas and storage racks to ensure that combustible loading remained acceptable but failed to incorporate adequate guidance for designating the storage area and constructing the racks to ensure nearby safety-related equipment would not be adversely affected during a plant
transient or seismic event. After the issue was raised, modifications to the scaffold storage locations were completed, as needed. The finding was more than minor because it was associated with the
Mitigating Systems Cornerstone attribute of design control (plant modifications) and it adversely impacted the cornerstone objectives. As a result of not evaluating the storage areas, safetyrelated components, systems or structures could have been affected. This finding was determined to be of very low safety significance because it did not result in loss of operability or functionality. The inspectors determined that the finding had an associated cross-cutting aspect of Problem Identification and Resolution, Corrective Action Program, Corrective Action (P.1 (d).
