| Title | Inadequate Work Instruction for Weld Repairs on the 11 component Cooling Heat Exchanger |
| Description | On September 16, 2009, the inspectors identified a finding of very low safety significance and a Non-Cited Violation of 10 CFR Part 50, Appendix B, Criterion V, for the licensees failure to have adequate work instructions associated with weld repairs on the 11 component cooling water heat exchanger. Specifically, the licensee failed to include the applicable American Society of Mechanical Engineers Code,Section XI, post weld acceptance criteria into Work Instruction 100611. As a corrective action, the licensee performed an inservice Code VT-2 visual examination to confirm that the heat exchanger was not leaking from the weld repair areas. The inspectors determined that this finding was more than minor because if left uncorrected, the failure to have adequate work instructions could become a more significant safety concern. Specifically, the failure to include a pressure test and Code VT-2 visual examination could result in undetected heat exchanger leakage affecting the operability of an inservice component cooling water train. This finding was of very low safety significance because it was a design or qualification deficiency, confirmed to not result in loss of operability or functionality. The inspectors determined this finding had a cross-cutting aspect in the area of Human Performance, adequacy of procedures, because the licensee failed to ensure that the work instruction for the weld repair on the 11 component cooling water heat exchanger was complete and up to date with the applicable Code requirements (H.2(c)) |
