Rush to judgment at Yucca Mountain



The Department of Energy (DoE) published a revised Civilian Radioactive Waste Management Program Plan late last year calling for an evaluation of “whether Yucca Mountain appears to be technically suitable for development as a geological repository” by the end of 1998. Almost concurrently, the DoE halted investigations that are critical for such an evaluation. These investigations concern the Calico Hills tuffs, the volcanic rocks that underlie the Topopah Springs welded tuffs that comprise the proposed repository.
