| Title | Licensee-Identified Violation |
| Description | Title 10 of the Code of Federal Regulation Part 50, Appendix B, Criterion XVI, Corrective Action, requires, in part, that Measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformance are promptly identified and corrected. Contrary to the above, the licensee failed to implement adequate corrective actions to prevent a recurrence of an oil leak previously discovered in July of 2004, on the Unit 1 B Reactor Building Spray Pump inboard bearing housing. Specifically, on April 28, 2011, a system engineer discovered oil leakage from the same Unit 1 Reactor Building Spray pump inboard bearing housing. The previous corrective action, which called for tightening of the bolts, failed to prevent the leak from reoccurring. The performance deficiency of failing to perform proper corrective actions to prevent the inboard bearing housing from leaking was determined to be more than minor because it was associated with the with the SSC and Barrier Performance attribute of the Containment Barrier Cornerstone and adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events and is therefore a finding. Using Manual Chapter 0609.04, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to have very low safety significance because the finding does not represent a degradation of the radiological barrier, or the smoke and toxic gas barrier functions provided for the control room, or does not represent an actual open pathway in the physical integrity of the reactor containment or a heat removal component. The issue was placed into the corrective action program as Condition Report CR-ANO-1-2011-588. |
