Title | Failure to Identify Leakage at Refuel Pool Cavity |
Description | The inspectors identified a Green non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, which states, in part, Measures shall be established to assure that conditions adverse to quality are promptly identified and corrected. Contrary to the above, the licensee failed to identify and correct a condition adverse to quality in a timely manner. Specifically, prior to February 19, 2013, the licensee failed to document the large area of boric acid leakage and corroded steel plates on the south primary shield wall of the containment refueling pool. The violation was entered into the licensees corrective action program as Condition Report 64213. The inspectors determined that the failure to promptly identify and evaluate a condition adverse to quality was a performance deficiency. The performance deficiency was more than minor because it affected the Initiating Events Cornerstone attribute of human performance and affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations, and if left uncorrected, the performance deficiency had the potential to lead to a more significant safety concern. Specifically, failure to implement corrective actions could result in increased leakage and further degradation of the safety system. Using Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, the inspectors determined that this finding was of very low safety significance (Green), because it was not a design or qualification deficiency, did not represent a loss of system safety function, and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. The finding had a cross-cutting aspect in the area of human performance associated with the work practices component because the licensee failed to define and effectively communicate expectations regarding procedural compliance and that personnel follow procedures. |
