| 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 be prescribed by documented procedures of a type appropriate to the circumstances and be accomplished in accordance with these procedures. Contrary to the above, on June 21, 2012, an activity affecting quality for the safety-related secondary containment damper 1VAD017B1 was not prescribed by documented procedures and accomplished in accordance with these procedures. Specifically, WO 4019934 was completed to rebuild the operator for 1VAD017B1 and did not direct the proper direction to adjust the stop rod adjusting nut and did not contain instructions for setting the open and closed limit switches. This resulted in the damper operator being set in a configuration where the damper indicated that it was fully closed when it was not. The licensee documented the issue in CR 01834595. The inspectors determined the finding could be evaluated using the SDP in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, Table 4a for the Barrier Integrity cornerstone. The finding screened as having very low safety significance (Green) because it only represented a degradation of the radiological barrier provided for the secondary containment. |
