Title | Licensee-Identified Violation |
Description | The following violation of very low safety significance (Green) was identified by the licensee and was a violation of NRC requirements which meet the criteria of the NRC Enforcement Policy for being dispositioned as an NCV. Facility Operating License NPF-90 for Watts Bar Nuclear Plant Unit 1, Condition 2.F, requires that TVA shall implement and maintain in effect all provisions of the approved fire protection program as described in the FPR. Contrary to the above, on April 18, 2011, the licensee found Fire Door A027 latching mechanism taped in a manner that prevented the door from automatically latching. The tape had apparently been placed there by an unknown individual during the refueling due to the inability to open the door from the auxiliary building side to the pipe chase side. The tape was removed restoring the fire door function and the latch assembly was replaced the next day. This was identified in the licensees CAP as PER 356803. This finding was of very low safety significance in accordance with IMC 0609, Appendix F, Attachment 1, Fire Protection SDP Phase 1 Worksheet, because the fire barrier was only moderately degraded and there were no fixed or in-situ fire ignition sources that would subject the degraded fire barrier to direct flame impingement. |
