At 09:02 on 07/28/07, an outplant operatorAt 09:02 on 07/28/07, an outplant operator identified that DOOR-18, which is a normally open fire door, had closed due to a failed fusible link. With this door closed, the pathway for a potential flood due to a high energy line break (HELB) is blocked therefore closing off a drain path for the water. This represented an unanalyzed condition where both divisions of essential switchgear could be impacted. As a result, both divisions of essential switchgear were declared inoperable and Technical Specification LCO 3.0.3 was entered. At 09:55 on 07/26/07, the closed fire door was restored to the open state. Both divisions of switchgear were declared Operable and LCO 3.0.3 was exited. No system actuations occurred as a part of this event.</br>The licensee notified the NRC Resident Inspector.ensee notified the NRC Resident Inspector.  +
