Identified By: NRC Identification Date: 11/29/2021 Significance: Green Item Type: Construction Finding Report: Vogtle Electric Generating Plant, Units 3 And 4 - NRC Initial Test Program and Operational Programs Integrated Inspection Reports 05200025/2021008, 05200026/2021008 Item Number: 05200026/2021008- 02 Note: Open in Report (NCV)

Failure to Follow Procedure CNSITPP-502

NRC inspectors identified a construction finding of very low safety significance and an associated NCV of 10 CFR, Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure to accomplish activities associated with local leak rate testing of electrical penetration 4-IDSC-EY-P29Y in accordance with procedure 4-CNS-ITPP-502, Containment Penetration Leak Rate (Type B)

Preoperational Test, Version 1.0. Specifically, the licensee failed to wait for flowmeter readings to stabilize prior to recording the leak rate data and inappropriately declaring the test acceptance criteria met. The licensee entered this issue into its CAP as CR 50116481.

The performance deficiency was determined to be of more than minor safety significance and thus a finding because it rendered the quality of a structure, system, or component (SSC) unacceptable or indeterminate and required substantial corrective action. The inspectors determined the finding was associated with the containment and was of very low safety significance (Green) because the issue did not affect a design function. The inspectors determined the finding had a cross-cutting aspect of training, in the area of Human Performance. Specifically, the organization failed to ensure that test personnel were trained to perform tests in a consistent manner.
