Title | Failure to Provide Procedure Appropriate to the Circumstance of Assembling the Zurn Strainer |
Description | The inspectors documented a self-revealing, non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings associated with the licensees failure to provide complete, accurate, and up-to-date procedures for proper installation of the gearbox coupling setscrews for Zurn Strainer A. The licensee entered this deficiency into their corrective action program for resolution as Condition Report CR-CNS-2012-04710. The licensees failure to provide complete, accurate, and updated procedures for proper installation of the gearbox coupling setscrews for Zurn Strainer A was a performance deficiency. This performance deficiency was determined to be more than minor and is therefore a finding because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone, in that an inadequate procedure caused a loss of a safety function of the A Zurn strainer, which affected the availability of the strainer; as such, this directly affected the associated cornerstone objective to ensure 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 inspectors determined that the finding is of very low safety significance (Green) because the finding: (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 its technical specification allowed outage time; and (4) did not represent an actual loss of function of one or more nontechnical specification trains of equipment designated as high safety significance in accordance with the licensees maintenance rule program. The inspectors determined that the apparent cause of this finding was that the licensees evaluation documented in Condition Report CR-CNS-2010-02213 had not resulted in appropriate corrective actions to address the cause of the Zurn strainer coupling failure. Therefore, this finding has a cross-cutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee did not take appropriate corrective actions to address safety issues and adverse trends in a timely manner, commensurate with their safety significance and complexity. |
