The inspectors identified a Green NCV of T … The inspectors identified a Green NCV of TS 5.4.1, Procedures, when PPL did not maintain adequate procedures to respond proactively to acts of nature. Specifically, PPLs adverse weather procedure did not ensure timely risk management activities for imminent adverse weather were completed despite a National Weather Service (NWS) declaration of a high wind watch, high wind advisory, and a tornado watch. PPL entered this item in their Corrective Action Program (CAP) as condition report (CR) 1628452. The issue was evaluated in accordance with IMC 0612 and determined to be more than minor since it affected the procedure quality attribute of the Initiating Events cornerstone and its objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, the inadequate procedure prevented PPL from taking proactive steps to limit the likelihood of high wind or tornado-related missile hazards upsetting plant electrical power systems. The finding screened to Green in accordance with IMC 0609, Attachment 4, and Appendix A, Exhibit 1, since it did not cause a reactor trip, involve the complete or partial loss of mitigation or support equipment, or impact the frequency of a fire or internal flooding event. The finding was determined to have a cross-cutting aspect in the area of Problem Identification and Resolution - CAP because PPL did not identify issues completely, accurately, and in a timely manner commensurate with their safety significance. Specifically, PPL did not identify that the Off Normal procedure was inadequate both during the 2011 periodic procedural review and during documentation of inspector observations in May 2012 as part of CR 1579977.vations in May 2012 as part of CR 1579977. +
