400728 19: Sun rays illuminate the desert February 7, 2002 north of Las Vegas, NV where the primary proposed rail route for transporting radioactive waste to the site of Yucca Mountain lies. Although the route would skirt around downtown Las Vegas, many residents dislike the idea of shipping 70,000 tons of nuclear waste over nearby highways and railroads. In January, the U.S. Department of Energy endorsed the Yucca Mountain plan. U.S. President George W. Bush could annouce his support for the plan as early as this week.
