| Title | Failure to Correctly Evaluate and Disposition of a Weld Indication |
| Description | The inspectors identified a finding of very low safety significance and associated NCV of Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Section 50.55a, for the failure to correctly disposition an ultrasonic (UT) examination indication found in feedwater weld 1FW87CA-6O/C08A as required by American Society of Mechanical Engineers (ASME) Code,Section XI. This issue was entered into the licensees CAP; the indication was re-examined and correctly dispositioned. The inspectors concluded that the finding was more than minor because a failure to perform the required corrective action could have allowed an unacceptable flaw to remain in service and so could become a more significant safety concern. The inspectors applied the IMC 0609, Attachment 0609.04, Phase 1 Initial Screening and Characterization of Findings to this finding. The inspectors concluded that the finding was of very low safety significance, because the licensee re-performed the UT examination, and correctly dispositioned the indication in accordance with ASME Code. Furthermore, the finding did not contribute to both the likelihood of a reactor trip, and the likelihood that mitigation equipment will not be available. The inspectors determined that this finding was related to the Decision Making Component (H.1(b)) for the cross-cutting area of Human Performance |
