TMI to Wrap up Business Starting in June

Three Mile Island, site of the United States’ worst commercial nuclear power accident, will begin a planned shutdown starting June 1 now that it is clear that it will not get a financial rescue from Pennsylvania. Exelon Corp., the Chicago-based energy giant said it would close the money-losing plant without what critics have called a bailout. The fight over Three Mile Island and Pennsylvania’s four other nuclear power plants invigorated a debate over the “zero carbon emissions” characteristics of nuclear power in the age of global warming and in one of the nation’s largest fossil fuel-producing states.
