Signaling that aging nuclear-power plants may face greater scrutiny, U.S. regulators have told utilities to more rigorously analyze metal fatigue at several sites, including two opposed by environmentalists.
The heightened scrutiny comes as a slew of older plants, dating to the late 1960s and early 1970s, seek operating-license renewals from the Nuclear Regulatory Commission. The NRC has extended the licenses of four dozen nuclear-power reactors since 2000. It is considering requests for nearly a dozen more, including Exelon Corp.'s Oyster Creek plant in New Jersey and Entergy Corp.'s Vermont Yankee plant, which have been targeted by environmentalists.
