HARTFORD, Conn. – Federal regulators say a pilot study of cancer risks posed to residents near seven nuclear power sites in the United States will update 22-year-old data, but an industry group says the study won't come up with anything new.

The Nuclear Regulatory Commission plans to study multiple cancer types in infants and the general population near six nuclear power plants, including the Dresden Nuclear Power Station in Morris, Ill., and a nuclear-fuel plant for the Navy.

The National Academy of Sciences recommended the sites in California, Connecticut, Illinois, Michigan, New Jersey and Tennessee because they represent a broad sample of plants with different operating histories, population sizes, and data in state cancer registries.
