| Title | Foreign Materials Control Procedure Not Followed Resulting in Degraded 21 Reactor Coolant Pump Seal Package |
| Description | A self-revealing NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified because Entergy personnel did not follow procedure 0-PMP-401-RCS, Reactor Coolant Pump Seal Package Inspection, to prevent foreign material from entering the 21 reactor coolant pump (RCP) seal package. Specifically, during the March 2010 refueling outage, Entergy personnel did not follow procedure 0-PMP-401-RCS and implement the foreign material exclusion procedural controls which resulted in a degraded 21 RCP seal package. Entergy personnel subsequently replaced the 21 RCP seal package and entered this issue into the CAP as condition report (CR)-IP2-2011-5052. The performance deficiency associated with this finding was that Entergy staff did not follow procedure 0-PMP-401-RCS to prevent foreign material from entering the 21 RCP seal assembly. This finding is more than minor because it is associated with the equipment performance attribute of the Initiating Events cornerstone and adversely affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, the foreign material introduced into the 21 RCP seal package resulted in an increase in the likelihood of tripping the 21 RCP due to further potential for degradation of the 21 RCP seal package. Additionally, if left uncorrected, the foreign material had the potential to further damage the seal package and result in a more significant safety concern. Using IMC 0609.04, Phase 1 Initial Screening and Characterization of Findings, the inspectors determined this finding was of very low safety significance (Green) because the finding would not result in exceeding the technical specification limit for RCS leakage and would not have affected other mitigation systems resulting in a total loss of their safety function. The finding has a cross-cutting aspect in the area of human performance associated with the work practices attribute because Entergy personnel did not define and effectively communicate expectations regarding procedural compliance and personnel following procedures. |
