| Title | Failure to Establish Emergency Procedures for Filling and Venting Diesel Fuel Oil Tanks after Tornado Damage |
| Description | The team identified a Green non-cited violation of Technical Specification 5.4.1(a), Procedures which requires, Written procedures shall be established, implemented, and maintained covering the following activities: (a) The applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. From April 4, 1984, to August 7, 2013, the licensee failed to establish procedures for filling and venting the emergency diesel generator fuel oil tanks after potential tornado damage. This violation was entered into the licensees corrective action program as Action Request 291543. Subsequently, the licensee implemented Night Order 1477 to provide interim procedural guidance to operators prior to developing a formal emergency procedure. The team determined that failure to establish procedures for filling and venting diesel engine fuel oil storage tanks after tornado damage in accordance with Technical Specification 5.4.1(a) was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it was associated with the procedures attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using the NRC Manual Chapter 0609, Appendix A, Exhibit 4, the inspectors determined a detailed risk evaluation was necessary because, during an external initiating event, the finding would degrade one or more trains of a system that supports a risk significant system or function; therefore, the senior reactor analyst performed a bounding detailed risk evaluation. The analyst determined that the change in core damage frequency was 1.2E-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. This finding had a crosscutting aspect in the area of problem identification and resolution, corrective action program component, 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. |
