Reports issued Tuesday to an independent federal review board could spell troubling news for backers of a nuclear waste dump at Yucca Mountain.
Scientists told the U.S. Nuclear Waste Technical Review Board that the climate at Yucca Mountain, 90 miles northwest of Las Vegas, has been and will again be cooler and wetter than it is today, providing more water to corrode metal canisters holding the highly radioactive waste.
Another scientist told the board's panel on the natural systems at Yucca Mountain that old Energy Department models of the rate that water seeps through the mountain's rock were inadequate, meaning that much more water may penetrate the mountain than once thought.
The issues discussed Tuesday shed light on potentially problematic issues for the Energy Department, which plans to begin storing 77,000 tons of nuclear waste in Yucca Mountain by 2010. The Energy Department plans to submit a license application with the Nuclear Regulatory Commission by December that would allow the agency to move forward with the plan to dump the waste.
t much of the water flowed off Yucca Mountain.
