The General Electric-designed nuclear reactors involved in the Japanese emergency are very similar to 23 reactors in use in the United States, according to Nuclear Regulatory Commission records.
The NRC database of nuclear power plants shows that 23 of the 104 nuclear plants in the U.S. are GE boiling-water reactors with GE’s Mark I systems for containing radioactivity, the same containment system used by the reactors in trouble at the Fukushima Daiichi plant. The U.S. reactors are in Alabama, Georgia, Illinois, Iowa, Massachusetts, Michigan, Minnesota, Nebraska, New Jersey, New York, North Carolina, Pennsylvania and Vermont.
In addition, 12 reactors in the U.S. have the later Mark II or Mark III containment system from GE. These 12 are in Illinois, Louisiana, Mississippi, New York, Ohio, Pennsylvania and Washington state. See the full list below.
