Title | Licensee-Identified Violation |
Description | 10 CFR 50, Appendix B, Criterion III, Design Control, stated, in part, that measures shall be established to assure that applicable regulatory requirements and the plants design basis are correctly translated into drawings, procedures, and instructions and that these measures shall provide for verifying or checking the adequacy of the design. Contrary to the above, from initial operation through March 24, 2012, the licensee did not provide measures for verifying or checking the adequacy of design changes to the site topography through grading and erection of structures. These changes were not evaluated to ensure that they did not adversely impact safety related SSCs due to water intrusion into the AB from PMP events. This violation was determined to be of very low safety significance (Green) because the loss of this equipment or function by itself, during the external initiating event it was intended to mitigate would not cause a plant trip or any of the Initiating Events used by Phase 2, would not degrade two or more trains of a multi-train safety system or function, and would not degrade one or more trains of a system that supports a safety system or function. The licensees evaluation demonstrated that water entering the Auxiliary Building could be removed through the use of installed plant equipment and the use of additional equipment, procedural guidance, and directed actions. The licensee entered this violation into their CAP as PIP O-12-4318. This LIV addresses a portion of URI 05000269, 270, 287/2012002-01. |
