| Title | Licensee-Identified Violation |
| Description | Title 10 of the Code of Federal Regulations Part 50, Appendix B, Criterion III, Design Control, requires, in part, that measures be established for the selection and review for suitability of application of materials, parts, equipment, and processes that are essential to the safety-related functions of structures, systems and components. Contrary to the above, prior to March 23, 2011, the licensee failed to establish the suitability of equipment located in the room 1206/1207 to function following a potential high-energy line break in nonnuclear, nonseismically analyzed auxiliary steam piping. The harsh environment from a high-energy line break had the potential to impact safety related level transmitters associated with the auxiliary feedwater loss of suction pressure transmitters ALPT0037, 38, and 39. This finding was entered in the licensees corrective action program as Callaway Action Request 201102329. Initial corrective action from the callaway action request demonstrated the piping was qualified to ASME Section III stress limits which allowed excluding intermediate pipe breaks. This finding was of very low safety significance since subsequent evaluation concluded the issue was a design or qualification deficiency confirmed not to result in loss of operability or functionality. |
