TRIBUTYL PHOSPHATE TECHNIQUE FOR SOLVENT REFINING OF NUCLEAR FUEL SOLUTIONS

摘要

FIELD: radiochemical industry. SUBSTANCE: technique used for solvent refining of nuclear fuel solutions such as uranyl nitrate and for removal of impurities from them includes bringing tributyl phosphate containing solvent in contact with nuclear fuel nitric solution. The latter is cleaned in advance from solid suspensions by passing it through layer of tributyl phosphate containing solvent. EFFECT: improved cleaning of nuclear fuel solution. 2 dwg
