| Title | Lack of Acceptance Criteria for Containment Visual Examinations |
| Description | The inspectors identified a non-cited violation of 10 CFR 50.55a(g)(4), for failure to define acceptance criteria for containment visual examinations. Consequently, active containment liner degradation (pitting) was identified and the liner returned to service without defined criteria for accepting this condition. The licensee entered this issue into the CAP as action requests AR01858862 and AR01861158, and developed visual examination acceptance criteria to restore compliance with this NRC regulation. The inspectors determined the finding to be more than minor in accordance with IMC 0612, Appendix B, Issue Screening dated September 7, 2012, because it adversely affected the Barrier Integrity Cornerstone attribute of maintaining the functional integrity of containment. The inspectors also answered Yes to the more-than-minor screening question, If left uncorrected, would the performance deficiency have the potential to lead to a more significant safety concern? Specifically, the lack of acceptance criteria in site procedures for containment visual examinations would become a more significant safety concern in that active liner degradation may not be properly evaluated and/or promptly corrected, resulting in a containment liner breach. In accordance with Table 2, Cornerstones Affected by Degraded Condition or Programmatic Weakness, of IMC 0609, Attachment 4, Initial Characterization of Findings, issued June 19, 2012, the inspectors checked the box under the Barrier Integrity Cornerstone because the corrosion induced pitting degraded the containment barrier. The inspectors determined this finding was of very low safety significance based on answering No to the Exhibit 3, Barrier Integrity Screening Questions, in IMC 0609, Attachment A, The Significance Determination Process (SDP) for Findings At-Power, issued on June 19, 2012. Specifically, the inspectors answered No to the screening question associated with an actual open pathway (e.g., breach) in the containment and No to the question associated with reduction in function of hydrogen igniters in containment. The inspectors determined that the primary cause of the failure to define containment visual examination acceptance criteria was related to the cross-cutting component of human performance, decision making, because licensee staff did not apply a systematic process, when faced with unexpected plant conditions, to ensure safety was maintained. Specifically, a systematic process for developing acceptance criteria was not applied for the containment visual examinations (H.1(a)). |
