Yucca Mountain's fault
Geologists working for the U.S. Geological Survey and the state of Nevada have discovered a new earthquake fault cutting directly through Yucca Mountain, the site slated for the nation's first high-level nuclear waste repository. Geologists believe the new sheer zone, combined with the already known Ghost Dance Fault, could reduce the underground space available for storing nuclear waste by as much as 20 percent. The fault could force the Department of Energy to undertake yet another major redesign of the proposed dump. The new fault zone will be among the issues discussed at an International High Level Waste Conference in Las Vegas in May.
