3 results about "Hexafluoride" patented technology

A container for storing high assay low enriched uranium hexafluoride (UF6) has a cylindrical lateral wall extending between first and second heads defining a container interior for receiving the radioactive material. A plurality of cylindrical poison rods extend in parallel through the container interior. Each of the poison rods has a neutron absorber. A plurality of access nozzles are situated within the first head and / or second head. Each of the access nozzles has a lateral wall defining a throughway that extends through the first head between an interior end region and an exterior end region. The interior end region captures and supports a respective end of a respective poison rod. The exterior end region is opened and closed via respectively detaching and attaching an end cap to thereby respectively expose and contain the respective poison rod.

This invention relates to the field of uranium resource technology, and more particularly to a direct reduction and conversion system for depleted uranium hexafluoride and its method of use. It includes: a liquid sodium supply unit for providing molten liquid sodium; a gaseous DUF6 supply unit for providing DUF6 that has been heated and stabilized to a gaseous state; a sodium thermal reduction reaction unit connected to both the liquid sodium supply unit and the gaseous DUF6 supply unit, wherein the liquid sodium and gaseous DUF6 react in the sodium thermal reduction reaction unit; a product separation unit connected to the sodium thermal reduction reaction unit for separating and classifying the solid products generated in the sodium thermal reduction reaction unit; and a tail gas recovery unit connected to the sodium thermal reduction reaction unit for condensing the gas discharged from the sodium thermal reduction reaction unit to obtain condensate, collecting sodium vapor and other volatile substances in the gas, purifying the gas, and discharging it after testing to ensure it meets emission standards. This method has a simple process, optimized reaction conditions, and is easier to implement.
