TREATMENT OF NEUTRON-IRRADIATED THORIUM

Patent ·
OSTI ID:4085939
Methods are given for irradiating thorium to produce U/sup 233/ and for chemically treating irradiated thorium to separate U/sup 233/ and Pa/sup 233/. After irradiation, thorium is disso lved in acid and (1) treated to precipitate the peroxides of thorium and uranium, (2) treated with Hf to precipitate thorium, or (3) treated to precipitate MnO/sup 2/, which carries down Pa/sup 233/. Auxiliary processes for purifying the separated elements are also given. (D.L.C.)
