| Title | Licensee-Identified Violation |
| Description | Title 10 CFR 50, Appendix B, Criterion XVI, requires, in part, that in the case of significant conditions adverse to quality, measures shall be established to assure the cause is determined and corrective actions are taken to preclude repetition. Contrary to the above, the licensee failed to establish corrective actions to preclude repetition for a significant condition adverse to quality. Specifically, the licensee failed to establish corrective measures to preclude repetition of motor operated valves failing due to pinion gear movement. In 2003, the licensee experienced a failure of a safety-related motor operated valve due to pinion gear movement. This issue was entered into the licensees corrective action program as a significant condition adverse to quality in Condition Report 03-1341. The licensees corrective actions included training, procedure revisions, and inspections. In October 2011, the licensee experienced another safety-related motor operated valve failure due to pinion gear movement, which was captured as Condition Report 11-19073, and was determined to be caused by narrowly focused and unnecessarily expedited inspections, and inadequate corrective actions from the 2003 event. This finding was of very low safety significance because it did not represent a loss of safety function. |
