A new mission for producing {sup 238}Pu has been proposed at the Hanford site. If approved, the program would produce {sup 238}Pu for National Aeronautics and Space Administration (NASA) space missions and possibly other speciality isotopes for medical and industrial applications. The {sup 238}Pu isotope is an excellent heat source and is currently used in generating electricity for deep-space applications. To produce {sup 238}Pu, special neptunium target assemblies would be irradiated for {approximately}2 yr in the Fast Flux Test Facility (FFTF) operated by Westinghouse Handford Company. After {approximately}1 yr of cooling, the neptunium pins would be reprocessed in special hot cells in the Fuel and Materials Examination Facility (FMEF) at the Hanford site to recover the {sup 238}Pu and convert it into the oxide form. The oxide could then be encapsulated in the FMEF using special materials and procedures to meet rigid NASA requirements. The plutonium oxide capsules would later become part of the radioisotope thermoelectric generators used by NASA to power equipment launched into space. To meet projected NASA mission requirements, the program would provide the capability to recover up to 30 kg/yr of {sup 238}Pu from {sup 237}Np targets by late 1993. The conceptual design for the program was completed by Westinghouse Hanford in September 1989 for validation and approval by the U.S. Department of Energy.
