Officials investigating Illinois reactor shutdown - Yahoo! News

Exelon Nuclear officials believe a failed piece of equipment at a switchyard at the plant about 95 miles northwest of Chicago caused the shutdown, but they were still investigating an exact cause. The switchyard is similar to a large substation that delivers power to the plant from the electrical grid and from the plant to the electrical grid.

The commission declared the incident an "unusual event," the lowest of four levels of emergency. Commission officials also said the release of tritium was expected.
