METHOD OF TREATMENT OF RADIOACTIVE SOLUTIONS AND UNIT FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC G21F9/04 

FIELD: physics, nuclear.

SUBSTANCE: offered group of the inventions relates to the devices for processing of radioactive solutions. In the offered method of processing of radioactive solutions before filling of the vessel with the solution in its bottom place an additional vessel from a thin dielectric film is placed. Then the radioactive solution is poured into the vessel, with adding of the substances for treatment process control. After that the solution is exposed to irradiation by unipolar electromagnetic impulses with the power more than 1 MW and with duration less than 1 ns, minimum frequency 1 kHz. The solution is treated within 10-30 minutes, held in the vessel during 1-4 days, then the treated solution is drained and additional vessel is removed for utilization. The offered unit contains a current-conducting housing (1), the central part of which contains electrode (2), designed as a horizontal plate. The plate repeats the housing cross-section shape, but have the sizes 20-30% from the cross-section area of the housing. The unit also contains the generator of unipolar electromagnetic impulses, located outside the housing (3). During the treatment at the bottom of the housing the additional vessel (4) is placed.

EFFECT: simplification of devices for treatment of radioactive solutions with keeping of high quality of cleaning.
