Title | Broken latch on Fire Door 145 |
Description | Inspectors identified a NCV of License Condition 3.F, having very low safety significance for failure to ensure that fire door 145 could be positively latched. Section 2-8.4.4 of National Fire Protection Association (NFPA) 80-1975, Fire doors and Windows, required that closing mechanisms be adjusted to overcome the resistance of the latch mechanism so that positive latching is achieved on each door operation. As a result of the discovery of a broken latch that prevented fire door 145 from positively latching, the licensee initiated an action request report (AR 864090864090, and established immediate actions to return fire door 145 to service. The licensee declared the fire door inoperable, issued fire impairment No. 1612 and established an hourly watch. Repairs to the door were completed and the fire door was declared operable the same day. The finding was determined to be more than minor because a lack of positive latching could result in the door opening during a fire, thereby allowing a fire to affect additional equipment important to safety in the exposed fire zone. Based on screening under IMC 0609, Appendix F, Fire Protection Significance Determination Process, the inspectors determined that a Phase 2 analysis was required. The inspectors determined that the change in core damage frequency associated with the finding was significantly less than 1 10-6 per year. As such, the finding was determined to be of very low safety significance (i.e., Green). This finding has a cross-cutting aspect in the area of Human Performance for the Resources component because the licensee did not provide adequate training to personnel. Specifically, as noted in the licensees corrective action document, annual training on fire barriers was inadequate in that equipment operators did not consistently challenge fire doors in accordance with training (H.2(b)).
