| Title | Potential Programmatic Breakdown of the Quality Assurance Program |
| Event Description | As a result of an extent of condition review for potential programmatic breakdown issues in response to an apparent violation 05000391/2013611-02 related to TVA's Commercial Grade Dedication Program. TVA has identified a previous Problem Evaluation Reports (PERS) that constitute significant breakdown in a portion of the Quality Assurance program. This review was initiated upon discovery of a misinterpretation of 10 CFR 50.55(e) where it was thought that to be reportable a 'significant breakdown in a portion of the Quality Assurance program' had to be associated with a confirmed substantial safety hazard.
The subject of the previous PER is as follows; On May 31, 2011, TVA identified a number of revised Drawing Revision Authorizations (DRAs) that had not been incorporated into work orders to ensure field work required by the DRA revision was implemented in the field. This condition was documented as PER 378571. TVA has concluded that a significant breakdown in a portion of the Quality Assurance program had occurred that could have produced a defect in a basic component. However, TVA has subsequently determined that no safety significance can be attributed to this condition. This issue has been resolved and PER 378571 was closed on February 19, 2013. These items are being reported in accordance with 10 CFR 50.55(e) as significant breakdown in a portion of the Quality Assurance program. The licensee has notified the NRC Resident Inspector. |
