METHOD FOR RADIOACTIVE DECONTAMINATION OF EQUIPMENT AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2014 - IPC G21F9/28 

FIELD: physics.

SUBSTANCE: invention relates to nuclear industry and can be used to decontaminate inner and outer surfaces of equipment. In the present invention, the equipment to be decontaminated is placed in a decontaminating solution and then exposed to ultrasonic vibrations, wherein the vibrations are excited in the entire volume of the equipment by providing hard acoustic contact of the surface of the equipment with acoustic ultrasonic radiators, wherein the vibrations are excited in form of pulses with filling frequency which corresponds to resonance frequency of radiators mounted on the equipment. The apparatus for realising the disclosed method comprises a container with the decontaminating solution, supports placed in the container for mounting the equipment to be decontaminated, an electric generator whose output is connected to the acoustic ultrasonic radiators, partially immersed in the solution; the radiators are equipped with waveguide-concentrators and are mounted on the back side in a clamp cover, which, through a weight load, provides hard acoustic contact of the waveguide-concentrators with the surface of the equipment.

EFFECT: enabling decontamination of objects with an inner cavity.
