| Title | Licensee-Identified Violation |
| Description | Title 10 CFR 50, Appendix B, Criterion V states, in part, that activities affecting quality shall be prescribed by documented instructions and procedures appropriate to the circumstances and shall be accomplished in accordance with these instructions and procedures. Contrary to the above, on November 5, 2012 and November 7, 2012, the licensee failed to incorporate ASME Code required VT-2 examination requirements into work instructions for work to be performed on a safety-related component. Specifically, WO 1453938-30 and WO 1453938-36, which required cutting and welding activities to be performed on the RHRSW system during installation of branched sub-assemblies, did not contain EC 385181 CC-AA-103, Attachment C. The EC 385181 CC-AA-103, Attachment C is the document that contained the requirement to perform a VT-2 examination immediately after sub-assembly installation as required by the ASME Code Section XI. On November 12, 2012, Project Management initiated IR 1439104, VT-2 Inspections Not Performed. Issue Report 1439104 identified that the required VT-2 had not been performed on the installed sub-assemblies under WOs 1453938-30 and 145398-36. This issue is more than minor because the performance deficiency, if left uncorrected, would have the potential to lead to a more significant safety concern. Specifically, not performing the VT-2 system pressure/leakage test following hot tapping the RHRSW line would call into question the quality of welds created during hot tapping of the RHRSW line and could potentially undermine the integrity of the RCS pressure boundary because that RHRSW line was in operation during the hot tapping process. This finding was determined to be of very low safety significance or Green in accordance with IMC 0609, Appendix G because at least one RHR loop (train A) was operable during the time period from when the hot tapping was performed to when the ASME Code required VT-2 was finally performed on the RHRSW Train B line. In addition, the sub-assemblies weld locations off the RHRSW train B line did not exhibit any system leakage during the VT-2 examination that was conducted on November 12, 2012. |
