  • Ill. nuclear reactor loses power, venting steam

    A nuclear reactor at a northern Illinois plant shut down Monday after losing power, and steam was being vented to reduce pressure, according to officials from Exelon Nuclear and federal regulators.

    Unit 2 at Byron Generating Station, about 95 miles northwest of Chicago, shut down at 10:18 a.m., after losing power, Exelon officials said. Diesel generators began supplying power to the plant, and operators began releasing steam to cool the reactor, but from the part of the plant where turbines are producing electricity, not from within the nuclear reactor itself, officials said.

    The steam contains low levels of tritium, a radioactive form of hydrogen, but federal and plant officials insisted the levels were safe for workers and the public.
