| Title | Failure to Remove or Evaluate Loose Debris Inside of Containment Prior to Applicable Mode |
| Description | The inspectors identified a finding of very low safety significance and associated Non-Cited Violation (NCV) of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure to follow procedure BAP 1450-1, Access to Containment. Specifically, the inspectors determined that the licensee failed to remove loose debris items from Unit 2 containment prior to Mode 4 or to perform an engineering evaluation per procedure. The licensee entered this issue into the corrective action program (CAP) as Issue Report (IR) 867171, removed the loose debris, 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. The inspectors evaluated the finding using IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 Initial Screening and Characterization of Finding, dated January 10, 2008, for the Mitigating Systems Cornerstone. Since this finding was not a design or qualification deficiency, did not result in loss of system or train safety function, and was not safety significant due to external events, this issue is screened as very low safety significance. This finding is related to the Work Control component of the Human Performance cross-cutting area for the licensees failure to coordinate work activities and the need for work groups to coordinate with each other. (H.3(b)) The personnel who left the material in containment assumed it was acceptable as they had documented the material in a surveillance data sheet, and the personnel who reviewed the completed data sheet assumed the material had been or would be removed from containment, and none questioned the potential impact upon the recirculation sump screens or coordinated with each other to ensure resolution of the material prior to a mode change |
