| 摘要 |
FIELD: processing and recycling wastes; nuclear physics.SUBSTANCE: invention relates to processing of irradiated nuclear fuel. Method of processing irradiated nuclear fuel includes voloxidation of fuel, removal of fuel of molybdenum, technetium and ruthenium, dilution of fuel. Removal of molybdenum, technetium and ruthenium is performed with hydrogen peroxide alkaline percolation. Percolation comprises preliminary operations of processing voloxidated fuel wit aqueous hydrogen peroxide solution, separation of liquid (L) and solid (S) phases, washing solid phase with water, separation of liquid and solid phases, processing of solid phase with aqueous sodium hydroxide solution, separation of liquid and solid phases, washing solid phase with water and separating liquid and solid phases.EFFECT: invention increases extraction of molybdenum, technetium and ruthenium from irradiated nuclear fuel until its dissolution.4 cl, 3 tbl |
