UNUSUAL EVENT DECLARED DUE TO DANGEROUS LEVELS OF CARBON DIOXIDE FOLLOWING A CARDOX RELEASE
"At 16:09 CST, the Control Room received a fire alarm on the Main Generator and actuation of the fire protection system. The Main Generator is protected by Carbon Dioxide for fire protection purposes. There was no evidence of a fire at the Main Generator. Air sampling of the Cardox Storage Tank Room indicated Carbon Dioxide levels at life threatening levels. An Unusual Event was declared at 1624 CST based on Emergency Action Level Chart P 'External Events and Chemical Spills' for a release of toxic or flammable gas on site AND portable monitors indicate toxic or explosive concentrations at life threatening levels of the gas near the spill area."
There were no personnel injuries reported and the licensee is conducting a survey to account for personnel. Ventilation of the affected areas is in progress to reduce the toxic gas levels.
The licensee informed state/local agencies and the NRC Resident Inspector.

"[The] declaration of Unusual Event has been terminated [at 1915 CST on 11/25/05]. The Control Room received a fire alarm on the Main Generator and actuation of the fire protection system. The Main Generator is protected by Carbon Dioxide for fire protection purposes. There was no evidence of a fire at the Main Generator. [The] source of Carbon Dioxide gas has been isolated. The area with [the] life threatening concentration of Carbon Dioxide has been ventilated. [The] plant no longer has any areas with [a] toxic concentration of Carbon Dioxide at the life threatening levels. Normal plant operation continues."
The licensee is continuing their investigation into the cause of the Cardox discharge.
The licensee informed stat/local agencies and the NRC Resident Inspector. Notified R3DO(Skokowski), NRR (Gillespie), IRD (Leach), DHS (Akers) and FEMA (Ligett).

OIL SPILL ON PLANT SITE
"On 11/25/05 at approximately 2120 hours, an oil spill occurred on plant site. During normal shift rounds, Power Operations observed oil coming from the overflow of an oil storage tank associated with the X-530 345KV under ground oil pumping station. A pump failed to shut off as required, allowing oil to be pumped to the storage tank until operator intervention shut down the pump.
"At 0020, 11/26/2005 hours, The Plant Shift Superintendent notified the National Response Center and the Ohio EPA that a Reportable Quantity (RQ) of insulating oil (Polybutene) was released to the ground. No material left the immediate area and clean-up of the spill is currently in progress.
"UE2-RA-RE1030, Appendix D, section P requires a 4 hour NRC event when other government agencies are notified."
The licensee reported this event to the National Response Center as report number 780580. The licensee notified NRC Region 2 (Hartland).
