Incidents at Nuke Plants

The reactor at Three Mile Island, site of the nation's worst nuclear accident, shut down automatically on Wednesday without posing a safety hazard after a turbine was tripped, a federal nuclear regulatory spokeswoman said.

The shutdown just before 6 p.m. was apparently caused by a disturbance on the electrical grid that tripped the turbine, which is powered by steam inside the reactor to generate electricity, Nuclear Regulatory Commission spokeswoman Diane Screnci said.
A cooling pump exploded at the Diablo Canyon nuclear plant, leading to a precautionary emergency shutdown of one of the two reactors.

No radiation was released and no one was injured in the Tuesday afternoon incident, Pacific Gas and Electric Co. said.
