| Title | Failure to Correct a Condition Adverse to Quality with Emergency Operating Procedures |
| Description | The team identified a Green non-cited violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, which states, in part, Measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected. Specifically, from August 16, 2013, to August 21, 2013, the licensee failed to implement a prompt compensatory corrective action to correct an adverse condition in emergency operating procedures that would have led to the loss of emergency core cooling pumps due to inadequate available net positive suction head. This violation was entered into the corrective action program as Action Request 292437. On August 21, 2013, the licensee implemented a night order giving guidance to monitor the pumps for cavitation and take actions to prevent degraded operation until the procedures are revised. The team determined that the failure to implement an interim compensatory corrective action to promptly correct an adverse condition in emergency operating procedures in accordance with 10 CFR 50, Appendix B, Criterion XVI was a performance deficiency. The performance deficiency was determined to be more than minor, and therefore a finding, because it was associated with the design control attribute of the Mitigating System cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the finding was more than minor because the procedures were in a condition that would adversely affect the licensees response to an emergency. Using the Manual Chapter 0609, Appendix A, Exhibit 2, the team determined the finding represented a loss of safety system function; therefore, the senior reactor analyst performed a bounding detailed risk evaluation. The analyst determined that the bounding change to the core damage frequency was less than 1.8E-8 per year (Green). Since the change in core damage frequency was less than 1E-7 per year, the finding was not significant to the larger early release frequency. The team determined that this finding has a crosscutting aspect in the area of problem identification and resolution, corrective action program, because the licensee failed to take appropriate corrective actions to address safety issues and adverse trends in a timely manner, commensurate with their safety significance and complexity. |
