What's wrong with taking nuclear waste out of the Yucca mountains?

presidents aren't always the most skeptical when it comes to heavy science issues, frankly the fears of what might happen to the waste in yucca mountain are out of proportion, there's not all that much, if any ground water there(that's why they choose the site) and its fairly remote, plus the storage containers are vary rugged, you can hit them with a train and not cause any leaks.
