DISSOLUTION OF IMPURE PLUTONIUM TETRAFLUORIDE IN NITRIC ACID

摘要

The optimum dissolution conditions were found for impure plutonium tetrafluoride (major impurities:Pu02 and MgO). They are:nitric acid concentration of 12 to 14 molar, reflux and stirring for up to two hours, solid-to-liquid ratio of 100 to 150 g/1, and addition of boric acid or aluminum nitrate.
