| Title | Transient Materials Not Removed from Containment Prior to Reactor Startup |
| Description | The inspectors identified a Green non-cited violation of Technical Specification (TS) 5.4.1 for the failure to properly implement procedure PLP-006, Containment Vessel Inspection Closeout, prior to startup following RFO 28. The improper closeout resulted in various tools as well as bags of consumable items and debris left in containment that could impact the containment sump strainer following an accident. The licensee initiated CR 640903, removed the items identified by the inspectors, and re-performed procedure PLP-006, Containment Vessel Inspection/Closeout, to further identify materials that should have been previously removed. The failure to remove debris and various temporary materials as required by procedure PLP-006 was a performance deficiency. The performance deficiency was determined to be more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the reliability and availability of ECCS equipment would be degraded by the introduction of material in to the containment that would impact and reduce the available area on the recirculation sump strainer. The inspectors determined that this finding is of very low safety significance (Green) because the finding did not represent an actual loss of function of one or more non-Tech Spec Trains of equipment designated as high safety-significant in accordance with the licensees maintenance rule program for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. This finding had a cross-cutting aspect in the Work Practices component of the Human Performance area, because the licensee failed to ensure that supervisor and management oversight of procedure PLP-006 ensured that debris was removed as required during containment closeout prior to reactor startup. |
