The inspectors identified an unresolved it … The inspectors identified an unresolved item (URI) related to a probable maximum precipitation (PMP) flooding event that could potentially affect safety-related equipment located on the roof of the reactor auxiliary building. During a walk-down of the reactor auxiliary building roof, the inspectors identified safety-related components, electrical conduit, and power cables that are vulnerable to a PMP flooding event. The inspectors questioned whether the licensee had performed an analysis to demonstrate that the safety-related components and electrical equipment related to conduits and power cables were adequately protected from a design basis PMP. At that time, the licensee could not identify an analysis that addressed the roof drains and scupper capacities of the area or if the safety-related equipment identified on the roof would function during and after a PMP event. The licensee entered this issue of concern into their corrective action program as CR-WF3- 2012-7520. The inspectors opened this unresolved item to determine if there is a performance deficiency associated with design control since the licensee did not have an analysis demonstrating adequate flooding protection. This item is unresolved pending a review of a flooding design analysis and other related documentation: URI 05000382/2012005-03: Reactor auxiliary building roof flood protection issue.iary building roof flood protection issue. +
