Title | Non-Conservative Main Steam Line Break Analysis |
Description | The inspectors identified a finding of very low safety significance and associated NCV of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the failure to correctly translate the design bases for the maximum steam generator narrow range level into procedures and instructions. This finding was entered into the licensees corrective action program. The finding was determined to be more than minor because an evaluation was required to ensure that accident analysis requirements for peak containment pressure were met. The finding also impacted the Barrier Integrity cornerstone attribute of procedure quality, and affected the cornerstone objective of maintaining the functionality of containment to protect the public from radionuclide releases caused by accidents or events. Procedural guidance was not adequate to maintain the plant within the parameters specified in the analysis for containment operability. The finding screened as having very low safety-significance (Green) because there was no actual barrier degradation. The inspectors determined there was no cross-cutting aspect associated with this finding. |
