DEVICE FOR PURIFICATION OF URANYL NITRATE FROM FISSION PRODUCTS Russian patent published in 2011 - IPC G21C19/46 C01G43/00 B01D9/02 

FIELD: power engineering.

SUBSTANCE: device has U-shape and is installed vertically. Connecting pipe 4 for supply of uranyl nitrate solution and connecting pipe 6 are arranged on the first side for combined output of mother water and spent washing solution. Connecting pipe 12 of washing solution 12 and drain branch 13 are made on the second side made in form of pipeline 7 with sectional heating jacket 14. Circular reactor 1 with conic bottom 2 and heating jacket 15 are located in an upper part of the first side of the device. Pipeline 7 with its one end is connected with conic bottom 2 of circular reactor 1, while with its another end it is connected with a pulsator via branch 11. Connecting pipe 4 for supply of solution of uranyl nitrate and additional connecting pipe 3 for supply of solution of sodium acetate are located under conic bottom 2 of circular reactor 1.

EFFECT: facilitation of continuous process of crystallisation, sedimentation and clarification of solution under conditions of multi-stepped front washing and high degree of purification of uranyl nitrate from fission products.
