NNSA Releases Draft Environmental Assessment for LANL Rad Lab; Raises Plutonium Limit 10 Times for Expanded Pit Production

Santa Fe, NM.

Today the National Nuclear Security Administration announced an Environmental Assessment to increase the amount of plutonium used in the Radiological Laboratory Utility and Office Building (aka the “Rad Lab”) at the Los Alamos National Laboratory from 38.6 grams of plutonium-239 equivalent to 400 grams. This 10-fold increase is significant because it will dramatically expand materials characterization and analytical chemistry capabilities in the Rad Lab in support of expanded plutonium pit production for future nuclear weapons designs. It also re-categorizes the Rad Lab from a “radiological facility” to a “Hazard Category-3” nuclear facility.
