Abstract

The invention provides a device for converting solid uranium hexafluoride into gas uranium hexafluoride. A receiving and supplying container comprises a hollow container body and a uranium hexafluoride tank arranged in the hollow container, wherein the uranium hexafluoride tank is connected with a receiving channel and a supplying channel separately; a cooling device is used for reducing a temperature in the uranium hexafluoride tank to a first preset temperature, and then a control device is used for making the receiving channel communicated to receive a supplied solid uranium hexafluoride material; a heating device is used for elevating the temperature in the uranium hexafluoride tank to a second preset temperature to make the solid uranium hexafluoride in the uranium hexafluoride tank gasify, and the control device is used for making the supplying channel communicated to supply the gas uranium hexafluoride outwards. According to the device for converting the solid uranium hexafluoride into the gas uranium hexafluoride, through cooperation of the cooling device, the heating device, the uranium hexafluoride tank and the control device, a process of receiving the material by the 1-L uranium hexafluoride container in a cooled state and then supplying the gas uranium hexafluoride outwards is completed, operation of shortening a complex tedious technology line and completing the technology line in one piece of equipment is achieved, and the operability is good.

Description

technical field [0001] The invention relates to the technical field of nuclear fuel, in particular to a device for converting solid uranium hexafluoride into gaseous uranium hexafluoride. Background technique [0002] Nuclear fuel elements are the core components of the reactor that are loaded in the reactor for self-sustaining nuclear fission to generate neutrons and release heat. With the continuous development of reactor technology, the manufacturing technology of nuclear fuel elements is also constantly developing and innovating, especially the continuous innovation of materials and structures of nuclear fuel elements, which puts forward newer and higher requirements for the manufacturing technology of nuclear fuel elements. With U-235-enriched nuclear fuel, nuclear fuel elements suitable for use in reactors must be made, which involves many manufacturing processes, and the requirements for the manufactured nuclear fuel elements are very high and very difficult. [0003...
