Overview

This note reveals engineering feasibility to produce plutonium-239 from depleted uranium, suggesting novel configurations of existing technologies.

Key Points

  • This note assesses the feasibility of producing weapons-grade plutonium-239 using depleted uranium.
  • Utilizes spallation on uranium with commercially available components.
  • Incorporates cold-crucible containment and an aqueous uranyl blanket.
  • Employs inline oxalate precipitation and assembles ten mature technologies in a new configuration.
  • Estimates production of 2–5 kg of Pu-239 per year in the mature phase.
