| Title | Failure to Establish and Implement Written Procedures for Operating Plant Equipment |
| Description | A self-revealing Green NCV of TS 5.4.1, Procedures, was identified involving the failure to incorporate the results of a Failure Modes and Effects Analysis (FMEA) completed in January 2010 into applicable operating procedures. The FMEA identified a vulnerability involving operator response to a loss of power to the RFP discharge isolation valves 3A (B, C) during the transfer from Discharge Pressure Mode (DPM) to Flow Control Mode (FCM). Specifically, PPLs FW operating procedures were not maintained to ensure operators could adequately recover RPV water level control when challenged with a system failure such as the condition that resulted in the Unit 2 scram on December 19, 2012. The PPL staff entered this issue into the CAP as AR-OPG- 1654037, CR 1666244, and CR 1666253. The finding was more than minor because it was associated with the procedure quality attribute of the Mitigating Systems Cornerstone and adversely impacted the objective to ensure the availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). The finding was evaluated using NRC IMC 0609, Attachment 0609.04, Initial Characterization of Findings, and Appendix A, User Guidance for Significance Determination for At-Power Situations, and screened as very low safety significance (Green) per Exhibit 2. The inspectors determined that this finding had a cross-cutting aspect in the area of Human Performance, Resources, because PPL staff did not ensure that procedures were complete, accurate and up-to-date to assure nuclear safety. Specifically, PPLs engineering modification procedures and checklists did not ensure that known single point design vulnerabilities were adequately addressed in FW procedures to ensure operators could adequately recover reactor water level prior to the Unit 2 reactor scram on December 19, 2012. |
