REACTION CHAMBER FOR PRODUCING URANIUM DIOXIDE POWDER BY PYROHYDROLYSIS FROM URANIUM HEXAFLUORIDE (VERSIONS) Russian patent published in 2013 - IPC C01G43/00 

FIELD: chemistry.

SUBSTANCE: invention relates to metallurgy, specifically to production of uranium dioxide powder by pyrohydrolysis. The reaction chamber for producing uranium dioxide powder from uranium hexafluoride is in form of a container, having a filtration zone, a first reaction zone for converting hexafluoride to uranyl fluoride and a second reaction zone with a gas-distributing plate for creating a fluidised layer for reducing uranyl fluoride to uranium dioxide, wherein the container has an inner distance between two opposite flat walls of not more than 104 mm for U²³⁵ enrichment of up to 5%. The reaction chamber can also be in form of a container which is divided by a vertical partition wall into cavities, each having a filtration zone, a first reaction zone and a second reaction zone.

EFFECT: invention provides nuclear safety of the reaction chamber.
