| Title | Failure to Translate Design Requirements to Operating Procedures for the Transfer of Residual Heat Removal and Containment Spray Suction to the Containment Recirculation Sumps |
| Description | Green. The team identified a Green noncited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, which states in part, that measure
shall be established to assure that applicable regulatory requirements and the design bases are correctly translated into specifications, drawings, procedures and instructions. Specifically, September 22, 2010, two out of two operating crews failed to satisfy the minimum time requirement for the transfer of suction o the residual heat removal pumps and the containment spray pumps to the containment recirculation sumps following a large break loss of coolant acciden with the worst single active failure as described in Table 6.3-12 of the Updated Safety Analysis Report. This finding was entered into the licensees correctiv action program as Condition Report 00028276. The team determined that the failure to translate design requirements into operating procedures was a performance deficiency. This finding was more than minor because it was associated with the Mitigating Systems Cornerstone attribute of design control and affected the associated cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the licensee failed to translate design requirements into Procedure EMG ES-12, Transfer to Cold Leg Recirculation. In accordance with NRC Inspection Manual Chapter 0609.04, Phase 1 - Initial Screening and Characterization of Findings, a significance determination screening was performed and determined that this finding was of very low safety significance (Green) because it was a design or qualification deficiency confirmed not to result in loss of operability or functionality. This finding had a crosscutting aspect in the area of human performance resources because the operating personnel were not trained to complete the transfer to cold leg recirculation within the minimum time to ensure the equipment was available to assure nuclear safety. |
