| Title | Licensee-Identified Violation |
| Description | Title 10 CFR 50, Appendix B, Criterion III, Design Control, requires, in part, that design control measures shall assure that appropriate quality standards are specified and that deviations from such standards are controlled. Contrary to the above, from initial plant operation until October 2011, the licensee failed to control deviations from standards of material applications inside containment. Specifically, the licensee failed to identify and prevent the use of aluminum in multiple containment airlock valve bodies and pressure gauges in containment. The finding was more than minor because it was associated with the containment configuration control attribute of the Barrier Integrity cornerstone and adversely affected the associated cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) For Findings At-Power, the inspector determined that the violation is of very low safety significance (Green) because the finding did not represent an actual open pathway in the physical integrity of reactor containment. The violation was entered into the licensees corrective action program as Condition Report CR-2011-005686. The licensee subsequently removed the affected pressure gauges and replaced the hydraulic valves. This is the enforcement aspect of the licensee event report discussed in Section 4OA3. |
