The U.S. Energy Dept.’s nuclear weapons complex will be smaller in 10 years, with more specialized facilities under a final environmental impact statement released by DOE’s National Nuclear Safety Administration. NNSA will consolidate complex-wide functions at certain sites, such as moving all plutonium research, development and manufacturing to Los Alamos National Laboratory in New Mexico and consolidating all highly enriched uranium work at the Y-12 complex in Tennessee. DOE also seeks to reduce the size of the weapons complex by eliminating up to 30% of its overall workforce through reassignment, officials say. Critics have opposed earlier versions of the EIS. A coalition of activists also has sued NNSA to halt plans to move the agency’s Kansas City-based complex, charging that the agency and the General Services Administration do not have a sufficient plan to manage environmental site cleanup there.
