| Title | Loose Debris Inside of Unit 2 Containment at the Start of the Refueling Outage |
| Description | The inspectors identified a finding of very low safety significance and associated Non-Cited Violation of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure to perform an engineering evaluation required by procedure when loose debris items was brought into Unit 2 containment prior to Mode 5. The licensee entered this issue into the CAP as IR 1058304 and completed an evaluation to verify that the containment sump was not adversely affected. The finding is more than minor because, if left uncorrected, the issue could have become a more significant safety concern. Since this finding did not result in loss of safety function for the containment recirculation sump, this issue is screened as very low safety significance. This primary cause of this finding is related to the Work Control component of the Human Performance cross-cutting area because the licensee failed to coordinate work activities and the need for work groups to coordinate with each other.
