| Title | Licensee-Identified Violation |
| Description | 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 of materials and parts that are essential to the safety-related functions of structures, systems, and components. Contrary to the above, in October 2012, the licensee failed to properly select an
review the suitability of application of several electrical cable splices and terminal strips during the replacement of safety-related electrical cables associated with the A and B SBDGs. Specifically, two modification packages associated the cable replacements during the 2012 RFO 23 did not appropriately evaluate the impacts of the stations environmental qualification (EQ) program and the effects of an internal turbine building flood. Because the SSCs maintained operability based on the deficiency affecting the qualification of the SSCs, the finding screened as very low safety significance (Green). This issue was documented in the licensees CAP as CR 01979556. Immediate corrective actions included a determination of operability (the SBDGs had no specified safety function for the EQ and turbine building flood events in question per the UFSAR), installation of a temporary flood barrier to compensat for the non-conforming condition for the A SBDG, cable splice and terminal strip replacement for the B SBDG, and the performance of a root cause evaluation. |
