| Title | Inaccurate Uswc PI Data Submittal |
| Description | The inspectors identified a Green Finding related to implementation of NDAP-QA- 0737, Reactor Oversight Process (ROP) Performance Indicators, Revision 9, and associated severity level (SL) IV NCV of 10 CFR 50.9(a), Completeness and Accuracy of Information because PPL staff did not accurately report the Unplanned Scrams with Complications (USwC) performance indicator (PI) for the period of October 2012 through December 2012. Specifically, PPL did not report the Unit 2 reactor scram, which occurred on December 16, 2012, in this PI. PPL entered the issue in their CAP as CR 1688235 and corrected the data on March 20, 2013.This scram, when combined with a second complicated scram, which was accurately reported in the same quarter, caused the PI to cross the Green-White threshold. This was discussed in an NRC follow-up assessment letter dated April 1, 2013 (ML13092A011). The finding was evaluated in accordance with IMC 0612 Appendix B, Issue Screening, which states, in part, that a performance deficiency is more than minor if it is related to a performance indicator and caused the performance indicator to exceed a threshold. In this case, when the December 16 scram was re-classified under the USwC PI, the performance indicator crossed the Green-White threshold. The inspectors evaluated the finding using IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At- Power and determined the finding did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available. Consequently, the finding is of very low safety significance (Green). Additionally, the issue was evaluated in the traditional enforcement process because it had the potential to impact the NRCs ability to perform its regulatory function. The inspectors determined the finding was a Severity Level IV violation using the examples of the NRC Enforcement Policy. Specifically, example 6.9.d.11 states a 10 CFR Part 50 licensee submits inaccurate or incomplete PI data to the NRC that would have caused a PI to change from green to white is an example of a SL IV violation. This finding has a cross-cutting aspect in the area of Human Performance, Decision-Making because PPL personnel did not communicate decisions and the basis for decisions to personnel who have a need to know the information in order to perform work safely, in a timely manner. Specifically, PPL did not adequately document the basis for determining the scram, which occurred on December 16, 2012, should be classified under the USwC PI to enable reviewers to adequately challenge the decision to ensure the appropriate classification was made. |
