Four items from today’s NRC Event Reports:
1. Wednesday evening, the Point Beach nuclear power plant in Wisconsin declared an Alert due to toxic gas in a vital area room. During a maintenace run on the plant’s emergency diesel generator, exhaust fumes caused a buildup of carbon monoxide in the Plant Instrument Air Compressor Room that exceeded the Immediate Danger to Life and Health standard set by the Occupation Safety and Health Administration. The diesel was turned off, and the Alert was terminated two hours later.
2. Later that night, the Cook nuclear power plant notified the state of Michigan that the Unit 2 main generator had leaked oil to the station’s absorption pond. An oil sheen covered approximately two acres of the pond. Cleanup efforts are now underway. The reactor is currently in cold shutdown.
3. The Surry nuclear power plant in Virginia reported to the NRC and the U.S. Fish & Wildlife Service that it found a dead bald eagle on the plant site on Wednesday. A fault in an onsite power line was thought to have caused the death of the bird.
4. And the Fermi nuclear power plant in Michigan had a valid actuation of the Unit 2 Reactor Protection System Wednesday morning. The automatic scram occurred during a Reactor Pressure Vessel Hydrostatic Test. Fermi officials said the shutdown occurred “due to issues related to controlling pressure near rated values.”
