| Title | Inadequate Instructions for the Inspection of the River Screen House and Essential Service Water Cooling Tower |
| Description | A finding of very low safety significance and an associated NCV of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified by the inspectors when licensee personnel failed to establish specific instructions for inspecting the River Screen House and Essential Service Water Cooling Tower. Specifically, the procedure that provided guidance for inspecting these structures lacked specific instructions on how to detect concrete degradation, erosion, corrosion and biological fouling. The licensee entered this issue into their corrective action program and initiated procedure revisions to provide further direction for identifying and documenting the degradation of these structures and related components. The performance deficiency was determined to be more than minor because if left uncorrected it would have the potential to lead to a more significant safety concern. The finding screened as of very low safety significance because it was a qualification deficiency confirmed not to result in a loss of operability or functionality. Specifically, a qualitative assessment of historic surveillance reports found the documented results acceptable. The inspectors determined that this finding did not represent current licensee performance and therefore no cross-cutting aspect was assigned. |
