IMPROVEMENTS IN OR RELATING TO THE PRODUCTION OF PLUTONIUM

Patent ·
OSTI ID:4819163
A process and an apparatus are described for carrying out the step of plutonimun oxalate precipitation from plutoniun nitrate solutions in a continuous and economical manner without criticality risks. In this process, plutoniun nitrate and oxalic acid solutions are fed to a stirred vessel at 80 deg C to effect precipitation, and the resulting slurry is passed by gravity flow to a cooler at 25 deg C and thence to a column having an upward flow feed of a washing mixture of oxalic and nitric acids. The precipitate settles to the bottom of the column, from which it may be continuously withdrawn through a valve. The apparatus is of eversafe geometry. (D.L.C.)
