Nuclear weapons stewardship meets local water politics in southeastern Michigan.
The proposed 220,000-square-foot facility would house one of two 55-megawatt supercomputers designed for what U-M and LANL call “nuclear weapons stewardship”—computational modeling that supposedly eliminates the need for physical testing.
