| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.4.1(a) requires that written procedures be implemented as recommended by Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Specifically, Regulatory Guide 1.33, Section 1.1, Plant Fire Protection Program, requires administrative procedures for plant fire protection. Procedure SEP-FPP-RBS-005, Duties of a Fire Watch, is an administrative procedure for plant fire protection. SEP-FPP-005, paragraph 5.2, requires a continuous firewater in the B Tunnel when the area water sprinkler is out of service. Contrary to this, on January 23, 2013, the continuous fire watch left his post without notifying his supervisor or waiting until a suitable relief fire watch had arrived. If a fire had occurred near that post, then that fire would not have been promptly identified, and therefore would have propagated further without mitigation. The performance deficiency is more-than-minor because it is associated with the protection against external factors attribute of the initiating events cornerstone and adversely affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The inspectors used NRC Inspection Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process, to evaluate the significance of this performance deficiency. A senior reactor analyst reviewed and concurred with the following evaluation. The exposure period was approximately 32 hours3.703704e-4 days <br />0.00889 hours <br />5.291005e-5 weeks <br />1.2176e-5 months <br />. This represented the summation of multiple short periods where the fire watch was not in the required position. The fire area included both Division 1 and Division 2 cables in a portion of the tunnel. Fire detection was available. Considering the short duration and the availability of fire detectors, the senior resident inspector determined that the performance deficiency represented a low level of degradation. As defined in Appendix F, a low level of degradation reflects a fire protection program element whose performance and reliability will be minimally impacted by the inspection finding. Therefore, the finding was of very low safety significance (Green). The issue has been entered into the licensees corrective action program as Condition Report CR-RBS-2013-00407. |
