| Title | Failure to Perform Magnetic Particle Examination on the 3/2/1501-20/20-10 U3 LPCI Support in Accordance with Procedures |
| Description | A finding of very low safety significance (Green) and associated non-cited violation (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 licensees vendor non-destructive examination (NDE) examiner failed to perform a magnetic particle (MT) examination in accordance with procedures on the 3/2/1501-20/20-10 Unit 3 low pressure coolant injection support. The licensee initiated corrective action document Issue Report (IR) 01135770 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. The failure to perform an adequate MT examination could have allowed undetected flaws to remain in service. 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. Specifically, no indications were identified when the examination was re-performed. This finding has a cross-cutting aspect in the area of Human Performance for the Work Practices component because the licensee proceeded in the face of uncertainty and unexpected circumstances by continuing to perform the examination after the equipment became damaged. The licensees examiner also elected to continue after identifying there was material present on the pipe in a location that could interfere with the exam. In addition, due to different circumstances surrounding the exam such as: component location, equipment weight, and environmental conditions, the examiner became tired. Nonetheless, the examiner elected to continue to perform the examination in this condition. |
