400728 04: A "no trespassing" sign warns people to stay away from the proposed nuclear waste dump site of Yucca Mountain (L) February 7, 2002 at Nellis Air Force Base, located approximately 90 miles north of Las Vegas, NV. In January, the U.S. Department of Energy endorsed a plan to transport vast amounts of radioactive waste from nuclear power plants across the nation for burial under Yucca Mountain, where it will take 10,000 years to decay. U.S. President George W. Bush could annouce his support for the plan, which is opposed by many in Nevada, as early as this week. (Photo by David McNew/Getty Images)

LAS VEGAS (AP) — After a decade in limbo, Nevada is pressing U.S. nuclear regulators to finally kill a mothballed proposal to entomb the nation’s most radioactive waste in the desert north of Las Vegas. A document submitted Tuesday to the Nuclear Regulatory Commission derides the Yucca Mountain plan as a “zombie-like” federal project that has remained on the books without funding for more than 10 years. The NRC offered no immediate comment. The U.S. has no long-term plan for managing or disposing of hazardous nuclear waste, but Energy Department officials have spoken recently about the need to find one. Federal funding for the Yucca Mountain site was halted under then-U.S. Senate Democratic Majority Leader Harry Reid and the Obama administration.
