| Title | Licensee-Identified Violation |
| Description | 10 CFR 50, Appendix B, Criterion III states in part that measures shall be established to assure that applicable regulatory requirements and the design basis, as defined in 50.2 and as specified in the license application, for those structures, systems, and components to which this appendix applies are correctly translated into specifications, drawings, procedures, and instructions. These measures shall include provisions to assure that appropriate quality standards are specified and included in design documents and that deviations from such standards are controlled. Contrary to the above, on June 15, 2012, licensee staff installed an incorrect part into the control air circuit of the 1B atmospheric dump valve which resulted in an unapproved design change to the plant. Specifically, the solenoid valve which controls air to the 1B atmospheric dump valve in local operation was replaced with a solenoid valve without a manual operator. The design deficiency was discovered during a training evolution by trainees attempting to implement the steps of an emergency operating procedure. The licensee entered this condition into their CAP as CR 482963. This finding was assessed using IMC 0609 Attachment 4 and Appendix A screening worksheets and was determined to be of very low safety significance (Green), because the finding is a deficiency affecting the design or qualification of a mitigating system SSC. |
