| Title | Licensee-Identified Violation |
| Description | On August 23, 2014, the licensee identified a degraded fire barrier that did not have a compensatory action assigned to it. Technical Specification 5.4.1.d, Fire Protection Implementation, for Units 1 and 2 required that written procedures be established, implemented, and maintained, covering activities related to Fire Protection Plan implementation. As part of the implementation, the licensee established procedures which provide guidelines for control of Fire Watch Activities. Procedure 12-FPP-2270
066-011, Fire Watch Activities, established the requirements for establishing compensatory fire watches. Specifically, Step 4.2.7 required inoperable fire barriers that are not already on fire watch to be placed on compensatory fire watch. Contrary to the above, from July 24, 2014 to August 23, 2014, the licensee failed to perform fire watche for Fire Door 1-DR-AUX471, the Unit 1 Control Rod Drive Equipment Room acces door. During this period, the CO2 closure device for the door was not capable of actuating automatically. The NRC previously documented NCV 05000315/2013009-01; 05000316/2013009-01 in Inspection Report 2013009, regarding the licensees failure t provide for automatic closure of this door. Although the licensee promptly established fire watch in response to the finding, on July 24, 2014, the licensee erroneously suspended the fire watch because thought they had made the required modification needed to allow the door to automatically actuate. The inspectors assessed the significance of the finding using IMC 0612, Appendix B. The finding was determined t be more than minor because it was associated with the Mitigating Systems cornerston attribute of Protection Against External Events (Fire) and adversely affected th cornerstone objective of ensuring the capability of systems that respond to initiatin events to prevent undesirable consequences (i.e., core damage). In accordance wit IMC 0609, Appendix F, Fire Protection Significance Determination Process, date September 20, 2013, Question A of Section 1.4.3, the inspectors concluded the findin was of very low safety significance (Green) because combustible loading on both sides o the wall were representative of a fire duration less than 1.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> and because it wa entered into the licensees Corrective Action Program as AR 2014-9970. |
