| Title | Failure to Promptly Identify and Correct a Condition Adverse to Quality |
| Description | The team identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Actions, involving the failure to promptly identify and correct a condition adverse to quality. Specifically, from August 2005 to July 15, 2013 the licensee failed to promptly identify and correct inadequate Class 1 structures wall thickness deficiencies to protect systems and components contained within from tornado generated missiles. The licensee resolved this issue by implementing changes to the facility through a licensing amendment that was reviewed and approved by the NRC. This issue has been entered into the corrective action program as Condition Report CR 2013-14363. The licensees failure to promptly identify and correct conditions adverse to quality was a performance deficiency. This performance deficiency is more than minor, and therefore a finding, because it is associated with the design control attribute of the Mitigating Systems Cornerstone, and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings at Power, the finding was determined to have very low safety significance (Green) because it: (1) was not a deficiency affecting the design or qualification of a mitigating structure, system, or component, and did not result in a loss of operability or functionality; (2) did not represent a loss of system and/or function; (3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time; (4) did not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety-significance in accordance with the licensees maintenance rule program; and (5) did not involve the loss or degradation of equipment or function specifically designed to mitigate a seismic, flooding, or severe weather event. The team determined this finding has a cross-cutting aspect in the area of human performance associated with the decision-making component involving the failure to use conservative assumptions in decision-making and adopt a requirement to demonstrate that the proposed action is safe in order to proceed rather than a requirement to demonstrate it is unsafe in order to disapprove the action. Specifically, in 2005 the licensee identified that wall thicknesses for areas of the auxiliary building and intake structure were less than design requirements. The licensee failed to enter this deficiency into the corrective action process and inappropriately used an alternate acceptance criteria that was not part of the facility licensing basis. |
