| Title | Failure to Evaluate and Adequately Monitor Activities Associated with the Internal Conditions of the Condensate and Refueling Water Storage Pool Structures |
| Description | The inspectors identified a noncited violation of 10 CFR 50.65(a)(3) because the licensee did not evaluate or adequately monitor activities associated with the condition of the condensate and refueling water storage pool structures. Specifically, the licensee did not evaluate the internal condition of the storage pools through the performance of appropriate preventive maintenance activities and did not evaluate these activities at least every refueling cycle, where practical, per industry-wide operating experience. As a result, there was no preventive maintenance developed for this activity even though industry-wide operating experience documented previous issues of concrete deterioration due to contact with boric acid over a long period of time. The licensee entered this issue into their corrective action program for resolution as CR-WF3-2011-1168. The planned corrective actions include the development of appropriate preventive maintenance activities to examine the internal condition of the storage pool structures during refuel outages. The finding was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and affects the cornerstone objective to ensure the availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, no preventive maintenance to monitor the internal condition of the storage pools, would impact the reliability of the structures. The inspectors evaluated this finding using Inspection Manual Chapter 0609 Attachment 4, Phase 1 Initial Screening and Characterization of Findings. The inspectors determined that the finding was of very low safety significance (Green) because the finding was not a design or qualification deficiency, did not represent a loss of a safety function of a system or a single train for greater than its technical specification completion time, and did not screen potentially risk significant due to external events. The finding had a crosscutting aspect in the operating experience component of the problem identification and resolution area because the licensee did not implement and institutionalize operating experience through changes to station processes, procedures, equipment, and training programs. |
