FIELD: radiochemical technology. SUBSTANCE: pulsed apparatus free of moving mechanical parts and mechanisms provides for trouble-free displacement of lumps of fuel elements in reaction chamber filled with fuel solvent. Problem is solved by developing container accommodating inclined perforated ramp. Pulsating process member of apparatus produces pulses in container solvent; perforation of inclined ramp is arranged so that solvent flows along ramp and upward. Discharge unit is used to remove empty fuel cans settling down on upper part of ramp. EFFECT: improved safety and capacity of apparatus. 23 cl, 6 dwg
