| Title | Licensee-Identified Violation |
| Description | Title 10 of the Code of Federal Regulations Part 50, Appendix B, Criterion III, Design Control, states, measures shall be established to assure that applicable regulatory requirements and the design basis, as defined in 10 CFR 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. Engineering personnel identified that the replacement containment spray Valve 3SI-V-0672 required chamfering of the valve disk to ensure valve operation, but was not performed. The licensee determined the cause to be that the design change was identified in previous Startup Field Reports 3SI-105, 112 and 114 during plant construction, but these startup field reports were not incorporated into the valve design basis including the drawing. This event has been documented in the licensee\'s corrective action program as Condition Report / Disposition Request 3314991.The finding is of very low safety significance because it did not result in a loss of- 47 Enclosure safety function, an actual loss of safety function of a single train for greater than its technical specification allowed outage time, or screen as potentially risk significant due to seismic, flooding, or severe weather initiating event |
