A FACILITY FOR THE PRODUCTION OF Pu$sup 238$
A pilot plant facility for recovering Pu and unconverted neptunium from irradinted neptunium target elements was operated for 17 months at the Savannah River Laboratory. The process required that the irradiated target elements be dissolved and the solution be processed through three anion exchange cycles for removal of undesirable fission products and cations, recovery of unconverted neptunium, and concentration of the Pu/sup 238/ solution. The process equipment was enclosed in three stainless steel boxes that were installed in two generalpurpose cells of a ten-cell complex. The basic cells were not modified. The two cells were not separated from the adjacent 8 cells. Containment of the high-specific-activity alpha emitters was accomplished by ventilation, development of handling techniques, use of procedures, and close radiation control coverage. The factlity was dismantled, and the cells were decontaminated and returned to normal use. With the exception of an accidental overexposure, all personnel exposures were kept below the administrative level of 3 r/yr. None of the personnel assimilated detectable amounts of the material handled. (auth)
