President-elect Donald Trump hasn't said whether he supports or opposes the Yucca Mountain disposal site, but a possible train route to haul radioactive waste from nuclear power plants could come within a half-mile of his Las Vegas hotel. Robert Halstead, executive director of the Nevada Agency for Nuclear Projects, said Friday the Trump hotel is within "800 meters of influence" of the railroad route that could carry more than 77,000 tons of high-level nuclear waste to the site about 90 miles from Las Vegas.
