| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to the above, on December 20, 2009, licensee personnel failed to follow procedure SO123-XV-50.CAP-1, Writing Nuclear Notifications for Problem Identification and Resolution, Revision 2, and enter conditions adverse to quality into the corrective action program. Specifically, when engineering inspections identified what appeared to be indications on emergency core cooling system suction piping train A on Unit 3, operations personnel were not informed, and an operability assessment was not performed. Subsequently, on January 13, 2010, while performing inspections on the Unit 3 emergency core cooling system suction piping, engineering personnel again identified indications and informed operations personnel, which resulted in the piping being declared inoperable until the ASME code case evaluations could be performed. This was licensee identified because licensee personnel identified the failure to follow procedures during follow up investigations. Using the Manual Chapter 0609, Significance Determination Process, Phase 1 Worksheets, this finding is determined to have a very low safety significance because the finding: (1) is not a design or qualification issue confirmed not to result in a loss of operability or functionality; (2) did not represent an actual loss of safety function of the system or train; (3) did not result in the loss of one or more trains of non-technical specification equipment; and (4) did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. The issue was entered into the licensee\'s corrective action program as Nuclear Notification NN 200756139 |
