YUCCA MOUNTAIN, Nevada (Reuters) – Will this barren mountain rising up to 4,950 feet from the Mojave desert look roughly the same in the year 1,002,008? That’s a million years into the future.

The question may sound bizarre but its answer is key to the future of a decades-old, controversial project to store America’s nuclear waste in the belly of Yucca Mountain, on the edge of a nuclear test site and 95 miles from Las Vegas. The narrow road from there winds through a desolate landscape of sparse vegetation — creosote scrub, cactus and gnarled Joshua trees.

“This is probably the world’s most intensely studied mountain,” says Michael Voegele, one of the senior engineers on the project, standing beside the “Yucca Mucker”, a 720-ton cylinder-shaped machine that has drilled a five-mile tunnel into the mountain. “And yet, there will be even more study.”

Indeed. In September, the U.S. Environmental Protection Agency (EPA) revised its original safety standards for what would be the world’s first deep underground nuclear mausoleum. Those standards were meant to protect the health of people living near Yucca Mountain for 10,000 years from the time the mountain is filled with 70,000 tons of radioactive nuclear waste.
