| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50, Appendix B, Criterion III, Design Control, requires, in part, that measures shall be established for the selection and review for suitability of application o
materials, parts, equipment, and processes that are essential to the safety-related functions of the structures, systems and components. Licensee procedure EES-5, General Fuse Selection Criteria and the Electrical Protection of 460 VAC and 125-250 VDC Motors, Revisions 0-7, is a procedure used to select and review the suitability of fuses in safety related applications. Contrary to the above, prior to November 4, 2014, the licensee failed to establish measures to review the suitability of application of materials, parts, equipment, and processes that are essential to the safety-related functions of the structures, systems and components. Specifically, the licensee failed to review the suitability of fuses used in safety related applications because procedure EES-5 did not specify that the actual full load amperage rating (as opposed to nameplate rating) of components be considered when selecting fuses. The finding was of very low safety significance because it was a design or qualification deficiency that did not result in a loss of operability or functionality. This issue was entered into the licensees corrective action program as AR 317288, 314956 and 315170. |
