| Title | Failure to Perform an Ultrasound Thickness Measurement of the Drywell liner in accordance with procedures |
| Description | A finding of very low safety-significance (Green) and associated NCV of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified by the inspectors for the failure to accomplish activities affecting quality in accordance with procedures. Specifically, the licensee non-destructive examination (NDE) examiner failed to perform an Ultrasound Thickness Measurement of the drywell liner in accordance with procedures. The licensee initiated corrective action document AR 01141740 to address the issue.
The finding was determined to be more than minor because if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically by failing to perform an adequate Ultrasound Thickness Measurement of the drywell liner potential degradation could have gone undetected. This finding is of very low safety-significance (Green) because the inspectors answered no to all of the characterizations worksheet questions in Table 4a of MC 0609.04. The inspectors determined this finding had no associated cross-cutting aspect because none of them represented the underlying cause for this violation to occur. |
