| Title | Licensee-Identified Violation |
| Description | Title 10 CFR 50, Appendix B, Criterion III, Design Control, requires, in part, that measures be established to assure applicable regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures, and instructions. Contrary to this, on or about May 25, 2012, the licensee identified the requirements associated with dynamic loading contained in the original construction code of the containment spray piping system was not incorporated into the specifications of the system and initiated AR 1370636. Specifically, the normally voided section of the containment spray piping had not been analyzed for dynamic loading during spray initiation as required by ASME,Section III, which was the original construction code. As a result, the licensee performed a dynamic loading analysis during spray initiation. The performance deficiency was determined to be more than minor because it was associated with the Containment Barrier Cornerstone attribute of structures, systems, components, and barrier performance and adversely affected the cornerstone objective of providing reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. The finding screened as of very low safety significance because the dynamic loading was verified to be within the capability of the piping design. |
