Nuclear Waste Disposal. One of the most controversial issues when discussing the possibility of nuclear power as an energy source is the disposal of the spent fuel rods. Yucca Mountain, the main proposed repository, has been studied for consideration for over ten years. What geological features of Yucca Mountain made it a potential waste site? What were the drawbacks of this location? Since President Obama took office, he has halted funding for the development of Yucca Mountain. What impact will this have on utilizing nuclear waste since an alternate waste site has not been selected? Is it a good idea to have all of the nation’s waste in one location or should it be spread out over several locations?
