| Title | Failure of an NDE Technician to Follow an Ultrasonic Thickness Examination Procedure |
| Description | A Non-Cited Violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, was identified by the inspectors for a contract Non-Destructive Examination (NDE) technicians failure to follow a procedure during an Ultrasonic (UT) examination of the Reactor Core Isolation Cooling (RCIC) barometric condenser shell. Specifically, the technician failed to properly perform a calibration of the UT examination equipment. The underlying performance deficiency (PD) associated with this violation did not result in a finding due to the minor safety-significance of the PD and hence the PD was not evaluated for cross-cutting aspects. Specifically, the PD was similar to Example 4b of IMC 0612, Appendix E, Examples of Minor Issues, in that, it involved an insignificant procedural error, failure to calibrate UT equipment per procedure. The failure had minimal impact on the UT readings (within UT test equipment tolerances). However, due to the willfulness of the violation, the violation was processed through the traditional enforcement process and assigned a Severity Level IV. Specifically, the NRC Enforcement Policy states that a violation may be considered more significant than the underlying non-compliance if it includes indications of willfulness. As part of its corrective actions, the licensee re-examined the technicians prior UT examinations and found insignificant variation between re-examined UT examination results and the technicians original UT examination result |
