SYSTEM FOR MICROWAVE TREATMENT OF LIQUID RADIOACTIVE WASTES DIRECTLY IN STEEL CONTAINERS WITH THEIR FURTHER SEALING FOR THE PURPOSE OF LONG-TERM SAFE STORAGE Russian patent published in 2017 - IPC G21F9/00 

FIELD: waste processing and recycling.

SUBSTANCE: invention relates to compactification of liquid radioactive wastes (LRW) for their further safe storage or recycling. System for microwave treatment of liquid radioactive wastes directly in steel containers with their further sealing for the purpose of long-term safe storage comprises a microwave generator, cover with an inlet branch pipe and removable container, forming a resonator, waveguide circuit connecting the microwave generator and resonator, EN-tuner, coupled to the waveguide circuit, and automatic control unit, is characterised by the fact, that a row of movable waveguide plungers is connected to the cover of the resonator, two directional couplers are coupled to the waveguide circuit on both sides of the EN-tuner, Circulator with waveguide load between the EN-tuner and microwave generator is coupled to the waveguide circuit, cover of the resonator is equipped with a throttle for connection to the container.

EFFECT: invention provides frequency tuning of the resonator, protection of the microwave generator due to its protection from reflected power by means of the circulator.
