A federal oversight board says Los Alamos National Laboratory has significantly underestimated how much radiation could leak from its main plutonium lab in the event of a major earthquake and fire.
The Defense Nuclear Facilities Safety Board says it has "identified a number of deficiencies" in calculations that concluded any release would be below the threshold deemed safe to the public.
Board staff say their calculations indicate the potential for a radiation release from a seismically induced fire could instead be more than four times that level.
