EMERGENCY DIESEL GENERATOR VENTILATION EXHAUST DAMPER COVERED WITH SNOW AND ICE

"During performance of a weekly preventive maintenance activity, [it was] discovered that the discharge dampers of Emergency Diesel Generator 102 Exhaust Fans opened approximately one inch vice full open as expected. Technical Specification 3.6.3e 14 day shutdown LCO was entered at 13:40. At 1350, Technical Specification 3.6.3e(1) was entered due to as found condition of both ventilation exhaust dampers for Emergency Diesel Generators 102 and 103 covered with snow and ice preventing normal operation of dampers. This condition required an initiation of normal orderly shutdown in one hour and the Reactor in cold shutdown condition within ten hours. At 14:10, Emergency Diesel Generators 102 and 103 were declared operable based on snow/ice removal and satisfactory completion of testing on all fans and dampers."

The Licensee notified the NRC Resident Inspector.
