| Title | Transient Materials Not Removed from Containment Prior to Reactor Startup |
| Description | The inspectors identified a finding of very low safety significance and associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to remove a plastic bag of transient materials that could interact with the containment sump recirculation strainer. Specifically, while performing the containment closure inspection prior to reactor startup, the inspectors identified a large plastic bag containing mop-heads and cleaning materials that, if left in containment, could interact with the containment recirculation sump suction strainer. The licensee took immediate corrective action to remove the items from containment. The issue was entered into the licensees corrective action program for resolution as action requests AR01781331 and AR01808631 for evaluation and development of additional corrective actions. The finding was determined to be more than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, dated September 7, 2012, because it was associated with the Mitigating System Cornerstone attribute of equipment performance and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the low head safety injection system availability and reliability could be reduced by material clogging the recirculation sump suction strainer. The inspectors evaluated the finding using IMC 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, Tables 2 and 3, dated June 19, 2012, and Appendix A, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 2 for the Mitigating Systems Cornerstone, dated June 19, 2012. The inspectors answered Yes to Exhibit 2, Question A.1 in Appendix A for mitigating structures, systems, and components, and functionality. Therefore, inspectors determined the finding to be of very low safety significance. The finding did not have a cross-cutting aspect because the cause was identical to the cause for the boric acid not being removed from containment isolation valve 2SC-955, as required by procedure, an issue also identified during the inspection, and the cross-cutting aspect was captured by that issue. |
