| Title | Failure to Translate TS 3.7.4 Requirements Correctly into Plant Procedures |
| Description | The inspectors identified a finding of very-low safety significance (Green), and an associated NCV of Title 10, Code of Federal Regulations (CFR) Part 50, Appendix B, Criterion III, Design Control, for the licensees failure to ensure instructions in plant procedures met the requirements as specified in the Technical Specifications (TSs). Specifically, the licensee failed to ensure that the caution statements as specified in the system operating procedures regarding the operability of the control center chillers when their associated Emergency Equipment Cooling Water Temperature Control Valve (TCV) was not in AUTO incorporated all the applicability modes for TS 3.7.4. The licensee entered this finding into their Corrective Action Program (CAP) as CARD 15-20790, and intended to revise the affected procedures to accurately translate TS 3.7.4 mode and plant conditions applicability requirements. The performance deficiency was determined to be more than minor because, if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, the licensee could potentially consider the control center heating, ventilation, air conditioning system operable during movement of recently irradiated fuel assemblies and operations with potential for draining reactor vessel conditions while th
TCV was not in the Updated Final Safety Analysis Report described AUTO design function and, therefore, challenged the control center habitability. The finding screened as of very-low safety significance (Green) because the finding did not represent a degradation of the radiological barrier function, or represent a degradation of the control room barrier function against smoke or toxic atmosphere. The inspectors did not identify a cross-cutting aspect associated with this finding. |
