INSTALLATION FOR COMPLEX PROCESSING OF LIQUID RADIOACTIVE WASTES Russian patent published in 2017 - IPC G21F9/04 

FIELD: physics.

SUBSTANCE: installation for complex processing of liquid radioactive waste (LRW) contains nodes of the LRW pre-treatment and sorptive after-treatment of the filtrate. The node of the LRW pre-treatment contains a cylindrical hermetical sealed container with a flat bottom provided with a stirrer. In the container cavity, there is a vertical tubular body of a removable bag filter with a gap with the bottom and hermetically connected to the top wall of the container. The stirrer contains a tubular shaft, with which two tiers of horizontal blades are fastened, the lower one of which is placed with a gap of 2-5 cm over the bottom, and the ends of its blades are 1.5-3 cm with the walls of the container. The blades of the upper tier are made smaller by the gap than the distance from the stirrer shaft to the filter body. The tubular shaft is attached to the discharge pipe. The upper part of the shaft is equipped with a gear wheel.

EFFECT: invention makes it possible to simplify the design of the plant and to ensure the use of one type of sorbent in the process of processing liquid radioactive waste.
