An alert was declared at 1:50 a.m. Saturday at the Peach Bottom nuclear power station about 70 miles southwest of Philadelphia after a transformer blew up at a substation about a mile away. It was one of two nuclear alerts in effect at the same time.
The all-clear came at 6:05 a.m., coincidentally followed at 6:30 a.m. by one in Omaha, Neb., where the Omaha Public Power District's Fort Calhoun nuclear power plant had been shut down late Friday after reactor coolant spilled out of a holding tank onto the floor of a containment building.
The Peach Bottom explosion caused a fire and an oil spill at the Peach Bottom Number 3 unit but no injuries and no evacuations, Philadelphia Electric Co. spokesman Neil McDermott said. And at the plant 12 miles northwest of Omaha, there also was no threat to the public or employees and no release of radiation into the atmosphere, spokesman Gary Williams said.
