Method for processing products of fusion-fission hybrid reactor fusion target chamber

Abstract

The invention provides a method for processing products of a fusion-fission hybrid reactor fusion target chamber, comprising steps of oxidation, condensation-gas-liquid separation, low temperature adsorption, fusion-bubbling, normal temperature adsorption, metal reduction, palladium-membrane separation, etc. The method of the invention avoids that constituents in the products of the fusion-fission hybrid reactor fusion target chamber are complex and unclear by oxidizing residual deuterium and tritium into water through introducing oxygen elements in the fusion target chamber, simplifies the processing source item and deuterium and tritium recycling technology, and adopts various processing technologies for gas state products and solid state products and guarantees relatively high recycling efficiency of the deuterium and tritium fuels. Besides, in the method for processing products of the fusion-fission hybrid reactor fusion target chamber, substantial Ar gas can be recycled, which saves cost. The method for processing products of the fusion-fission hybrid reactor fusion target chamber can recycle the residual deuterium and tritium fuels with recycling rate over 95%, which satisfies deuterium self-sustaining of the fusion-fission hybrid reactor and requirements for safety, economy and environment protections.

Description

technical field [0001] The invention belongs to the field of hybrid energy reactors, in particular to a method for processing fusion target chamber products of a fusion-fission hybrid reactor. Background technique [0002] With the shortage of fossil fuels and the increasing seriousness of environmental pollution, fusion energy has gradually attracted people's attention. In the development of fusion energy, Z-pinch driven fusion-fission hybrid energy reactor (Z-FFR) is considered to be a relatively easy way to realize. In the current design of Z-FFR, the fuel consumption of deuterium-tritium fuel fusion is about 30%. If the fusion power is 25MW and the target frequency is 0.1Hz, the remaining tritium per day is 7.06g. Together they are discharged from the fusion target chamber. Since tritium is radioactive and is a scarce and strategic resource with high prices, from the perspective of safety, economy and environmental protection, it is necessary to process the products of...

AI Technical Summary

Problems solved by technology

Since the Z-FFR experimental reactor and the Tokamak device are different in driving mode, fusion reaction chamber atmosphere, deuterium-tritium fusion reaction mode, etc., there are huge differences between the fusion reaction product composition, residual tritium concentration, and distribution form of Tokamak, such as Tokamak The remaining deuterium-tritium concentration in the ash exhaust gas is more than 80%, all of which exist in the form of gas; while the remaining deuterium-tritium concentration in the fusion target chamber product of the Z-FFR experimental reactor is only 10%. -7 The following, and its existence form is not clear

Therefore, the fusion target chamber product processing route of the Z-FFR experimental reactor is significantly different from that of Tokamak. The ash exhaust gas treatment method for Tokamak cannot be directly applied to Z-FFR. It must be based on the composition and characteristics of the target chamber product of the Z-FFR experimental reactor. Develop new technical methods and processes
