State agency testing area around Byron nuke plant

The Illinois Emergency Management Agency is collecting samples around the Byron nuclear power plant to make sure there are no potential hazards to the public.

A failed piece of equipment at a switchyard at the Byron Generating Station caused the Exelon plant to shut down Monday morning.

Company officials say steam containing low levels of radioactivity was vented to reduce pressure after the power loss. Diesel generators were supplying the reactor with electricity.

State officials say they do not expect to find hazardous levels of radioactive tritium, but they are checking the area.

The incident has been declared an 'unusual event' by officials. That is the lowest of four levels of emergency.
