A federal regulator has authorized the owner of Millstone Power Station in Waterford to adopt a new method for measuring radiation exposure to workers. The decision by the Nuclear Regulatory Commission also applies to Dominion's fleet of reactors around the country. The approach, established by the Health Physics Society, uses gauges known as dosimeters to measure the dose of radiation a worker has been exposed to in seven different areas of the body, said Neil Sheehan, an NRC spokesman. The measurements are taken in plant locations where higher exposure is likely, he said.

The U.S. Nuclear Regulatory Commission will delay license review for a new nuclear reactor at the existing Nine Mile Point nuclear power station in New York at the request of UniStar Nuclear Energy LLC, the NRC said on Friday. UniStar is a joint venture of Maryland-based Constellation Energy Group (CEG.N) and EDF Group (EDF.PA) of France formed to pursue building new U.S. reactors. UniStar said it wants the NRC to hold off on the Nine Mile license to focus attention on UniStar's planned reactor at the Calvert Cliffs plant in Maryland. Earlier, UniStar dropped Nine Mile out of the competition for federal loan guarantees for nuclear power, also to concentrate on the Calvert Cliffs proposal.
