| Title | Failure to Install Torus Coating in Accordance with Established Processes |
| Description | An apparent violation of 10 Code of Federal Regulations (CFR) Part 50, Appendix B, Criterion IX, Control of Special Processes, was self-revealed for the failure to install the torus coating under suitable controlled conditions. Specifically, inadequate quality controls during the application of the torus coating resulted in unqualified torus coating in excess of the debris loading design margin of the emergency core cooling system (ECCS) suction strainers.

The performance deficiency was determined to be more than minor because it wa
associated with the Mitigating System Cornerstone attribute of design control and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The finding has been preliminarily determined to be White, a finding of low-to-moderate safety significance, because it affected the function of the low-pressure ECCSs. The team determined that this finding had a cross-cutting aspect in the area of Human Performance because licensee senior managers did not ensure supervisory and management oversight of work activities, including contractors and supplemental personnel.
