ABSTRACT:
A process for fabricating weapons-grade plutonium into mixed-oxide fuel for use in a nuclear reactor. The plutonium is converted into plutonia powder at a site remote from the fuel fabrication facility and then the plutonia powder is pressed and fired into high-density plutonia pellets for transport to the fuel fabrication facility. The high-density plutonia pellets serve as a diversion-resistant and environmentally sound method of shipping the plutonia for use as a feed material. Comminution methods are employed to reduce the plutonia pellets to a fine powder for blending with urania feed to produce mixed oxide acceptable for reactor operation.
