Event Description | At 1925 [hrs. CST], the Main Control Room received a notification of smoke in the Auxiliary Building Ventilation Supply Plenum. Fire Brigade and the Incident Commander were dispatched. Once [they] arrived at the scene, they noted smoke in the area of the 0C VA Supply Fan and requested the fan be shutdown. The 0C VA supply fan was shutdown at 1933 hrs. The operators reported smoke and a small fire coming from the inboard bearing of the 0C VA supply fan. A CO2 fire extinguisher was used to put the fire out and cool the bearing. A total of 2 extinguishers were used. The fire was declared out at 1941 hrs. Both Units remained stable and at full power during the entire event.
