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.
***** Event Retracted. From Hicks to Taylor on 3/4/04 at 1020 EST*****
"This Event Notification is being made to rescind previous Event Notification made on 2/05/2004. The notification was made as an eight hour report per 10 CFR50.72 (b)(3)(v)(D) and an LER IAW 10CFR50.73(a)(2)(v)(D) and (vi).
"Subsequent Engineering evaluation has concluded that the Emergency Diesel Generators (EDGs), and more specifically their Room Ventilation Fans (Support System) would have performed their design function.
"The specific event described a snow and ice condition that impeded the Ventilation Fan Dampers from fully opening. The dampers did however, partially open. Engineering has concluded that although there was reduced ventilation flow through the dampers, the air flow rate through the reduced exhaust fan opening would have melted the snow and ice. The melting would have occurred at a progressively faster rate (as the exhaust flow rate and room air temperature both increased) and eventually provided adequate ventilation flow to maintain normal room temperature."
Notified R1DO (Todd Jackson).

OFFSITE NOTIFICATION TO THE MISSOURI PUBLIC SERVICE COMMISSION
"At 1701 [CST] on 02/05/2004, a report was made to the Missouri Public Service Commission (MPSC) to notify the MPSC of a forced outage at the Callaway Nuclear Plant. This notification is reportable under 4CSR240 20.080(3)(B) because the outage is expected to last longer than 72 hours. At 0439, 02/03/04, Callaway Plant experienced a reactor trip while operating transmission breakers located in the plant switchyard. It was determined on 02/05/2004 that the outage was expected to last longer than 72 hours."
The Licensee will inform the NRC Resident Inspector of the MPSC notification.
