This note reveals engineering feasibility to produce plutonium-239 from depleted uranium, suggesting novel configurations of existing technologies.
A system for producing weapons-grade plutonium-239 from depleted uranium using commercially available components. Combines spallation on uranium, cold-crucible containment, aqueous uranyl blanket, and inline oxalate precipitation. Ten mature technologies are assembled in a configuration not previously published. Estimated 2–5 kg Pu-239/year in mature phase.
