The invention relates to the nuclear industry in terms of processing radioactive waste, namely, devices for dissolution and erosion of streams of sludge accumulated at the bottom of storage tanks for liquid radioactive waste of any level of activity, translation insoluble solid phase of the sediment in suspension and the issuance of the suspension from the storage tanks for recycling. In addition, the device can be used in the chemical industry for mixing, averaging concentrations of reagents in containers and their issue.

A known design for sediment erosion and decontamination containing washing head with nozzles, a cylindrical housing with a chamber for working fluid, provided with an inlet valve and communicating with the distribution unit using Flex, polycaproamide, and with a washing cylinder chamber is communicated through the discharge pipe, and between the housing and the actuator is equipped with a crank-beam mechanism (see RF Patent №2138870, CL. G 21 F 9/34, 1999).

The disadvantages described above of the known device is that during operation by a flexible pipeline blown exhaust compressed air from the chamber, and when possible depressurization contamination may occur as the device itself, and facilities for maintenance. In the line is the use of this device in the tank it is necessary to place an additional suction pump that requires you to do more driving in the tank and leads to the cost.

Use as a drive device rotates the drive and the crank-beam mechanism provides a reciprocating rotary movement of the device in sector 90°that requires at least four nozzles. If necessary erosion private limited plot sediment part of the jets will be used inefficiently, because this site is directed only one nozzle. In addition, the complicated exact orientation of the nozzle in the desired direction as the rotation angle of the device is not connected linear dependence with the angle of rotation of the drive.

This pulsation valve submersible pump and was chosen by the applicant as a prototype.

The obstacles to achieve specified below technical is the result when using the known device, is that in the process of operation scour sediment liquid is in the tank, is made simultaneously with its issuance, therefore, the concentration of solid phase in the issued suspensions, especially at the beginning of operation of the pump, very low. This leads to an increase in the volume of liquid radioactive waste and, therefore, the cost of processing. In addition, displaced from the housing, the suspension is continuously divided into two unregulated flow: injection and flexible pipes, which not only reduces the efficiency of the jet resulting from Flex, but also creates the danger of blocking the discharge line of the pump settling the solid phase of the pumped slurry, given the pulsed mode of the fluid in the pipeline. Chaotic motion Flex under the action of the reactive forces resulting jet is not effective due to the inability of the electoral erosion of sediment in some areas the capacity and reduce the energy of the jet because of its costs for moving Flex.

SUBSTANCE: invention relates to method for reprocessing of polymetal, multicomponent, thorium-containing radwastes, formed when reprocessing of various mineral, containing rare-earth elements, Nb, Ta, To, V, Zr, Hf, W, U, etc. Method includes treatment of solution and/or slurry with alkaline agent; introducing of sulfate-containing inorganic compound solution and barium chloride; treatment of obtained hydrate-sulfate slurry with iron chloride-containing solution, and separation of radioactive precipitate from solution by filtration. As alkali agent magnesia milk containing 50-200 g/dm2 of MgO is used; treatment is carried out up to pH 8-10; sodium sulfate in amount of 6-9 g Na2SO4/dm2 is introduced as solution of sulfate-containing inorganic compound; barium chloride solution is introduced in slurry in amount of 1.5-3 g BaCl2/dm2. Hydrate-sulfate slurry is treated with solution and/or slurry containing 0.8-16 Fe3+/dm2 (as referred to startingsolution) of iron chloride, followed by treatment with high molecular flocculating agent and holding without agitation for 0.5-2 h. Radioactive precipitate is separated from mother liquor, washed with water in volume ratio of 0.5-2:1; then washed with sodium chloride-containing solution and/or slurry in volume ratio of 0.5-2:1; radioactive precipitate is removed from filter and mixed with mineral oxides in amount of 0.5-0.8 kg MgO to 1 kg of precipitate. Formed pasty composition is fed in forms and/or lingots and presses with simultaneous heating up to 80-1200C.

EFFECT: filtrate with reduced radioactivity due to increased codeposition coefficient of natural Th-232-group radioactive nuclide, in particular Ra-224 and Ra-228, with radioactive precipitates.
