Finding

Title

Failure to check the adequacy of the design for the Reactor Vessel Head structural elements

Description

The inspectors identified a green, non-cited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the licensees failure to ensure the design of the reactor vessel head stand met current licensing basis requirements. Specifically the design of the reactor vessel head stand did not meet the requirements as defined in the Updated Safety Analysis Report. Subsequently, the licensee evaluated the non-conformances to provide a reasonable assurance of operability, and planned corrective actions to restore the structures to design basis requirements. The failure to ensure the design of structures, systems, or components meet their current licensing basis is a performance deficiency. The licensee documented the finding in the corrective action program as Condition Report 2014-04218. The performance deficiency was determined to be more than minor because it adversely affected the Mitigating Systems cornerstone objective of ensuring the availability, reliability, and capability of the safety injection system and the shutdown cooling system. The inspectors evaluated the finding using Inspection Manual Chapter 0609, Appendix G, Shutdown Operations Significance Determination Process (SDP), Attachment 1, Shutdown Operations Significance Determination Process Phase 1 Operational Checklists for Both PWRs and BWRs, dated May 25, 2004, and determined that the finding is of very low safety significance (Green) because the finding did not require quantitative assessment. The finding has a crosscutting aspect in the area human performance because the licensee did not ensure the CIS at elevation 1045 ft. for storage of the reactor vessel head maintained adequate design margin.
