| Title | Licensee-Identified Violation |
| Description | Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Appendix B, Criterion III, Design Control, requires, in part, that measures shall be established to assure that applicable regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures, and instructions. The reactor coolant system is a safety-related system, and therefore requires measures to assure the design basis is correctly translated into specifications, drawings, procedures, and instructions. Contrary to this requirement, on March 28, 2008, the reactor coolant system design basis was not correctly translated into specifications, drawings, procedures, and instructions because it did not combine the loads from a loss-of-coolant-accident (LOCA) and an earthquake. This finding was identified by the licensee and entered into the corrective action as Notifications 50403188 and 50404966. The finding was determined to be of very low safety significance because the reactor coolant system maintained its operability. |
