The inspectors identified a Green NCV of 1 … The inspectors identified a Green NCV of 10 CFR 50.65(a)(4) because PSEG did not did not implement prescribed risk management actions (RMA) while both Unit 2 pressurizer (PZR) power operated relief valves (PORV) were isolated. PSEGs corrective actions included adding the requirement for operators to record protected SSCs in the control room narrative log and training operators on the risk assessment process. This finding was more than minor because PSEG did not implement a prescribed significant compensatory measure for an identified yellow risk condition. Specifically, PSEG did not implement equipment risk awareness and control measures while both PZR PORVs were isolated, and conducted testing on a protected component without the required written authorization and supervision. The inspectors completed a Phase 1 screening of the finding per Appendix K of Inspection Manual Chapter (IMC) 0609, Maintenance Risk Assessment and Risk Management Significance Determination Process. The inspector determined that the incremental core damage probability (ICDP), based on PSEGs risk analysis of the event, was 5.6E-8. Therefore, the inspectors determined the finding to be of very low safety significance (Green) because the ICDP for the event did not exceed 1.0E-6. The finding had a cross-cutting aspect in the area of human performance because PSEG did not define and effectively expectations regarding procedural compliance and personnel did not follow procedures (H.4(b)). Specifically, operators did not implement the RMAs specified by an approved risk assessment per PSEG work management and operations procedures. (Section 1R13t and operations procedures.
