Description
Technical Field
The invention relates to the technical field of nuclear fuel, in particular to an online preparation and supply demonstration system for multi-component deuterium-tritium fuel ash discharge gas.
Background
Fusion energy is considered to be the most important energy source mode for human beings in the future because of wide sources of fuels, huge release capacity and far lower radioactivity than nuclear fission. The fusion energy is generated mainly by utilizing isotopes of hydrogen, namely deuterium (D) and tritium (T), wherein the isotopes of hydrogen, namely D+T- & gt n (14.06 MeV) + 4 He (3.52 MeV), and the fuel of deuterium and tritium injected into a reactor vacuum chamber (the place where the fusion reaction of deuterium and tritium occurs) is burnt up by less than 5 percent each time, so that the fuel needs to be recycled, and meanwhile, impurities, such as 4 He, H 2 and the like, are gradually increased due to the gradual consumption of D, T, so that the plasma is gradually cooled. In order to maintain the operation of the reactor, the "burned" gases, otherwise known as ash, are continuously removed from the vacuum chamber, recycled through the plasma exhaust, and injected back into the vacuum chamber through the fueling system.
Therefore, the magnetic confinement fusion reactor deuterium-tritium fuel internal circulation demonstration experiment system is designed and is mainly used for simulating and demonstrating the circulation process of recovering, purifying, separating, preparing specific proportion deuterium-tritium gas and the like from a fusion reaction vacuum chamber and then supplying the deuterium-tritium fuel to the vacuum chamber again in the fusion reactor operation process.
In order to verify that the gas treatment circulation loop of the magnetic confinement fusion reactor deuterium-tritium fuel internal circulation demonstration experiment system can achieve steady-state operation, the gas with uniform multicomponent components (deuterium-tritium and 4He、Ar、Ne、CH4 gas with a certain proportion) needs to be dynamically prepared in real time so as to simulate the burnt gas components under the reaction working condition of a vacuum chamber and serve as the ash discharge gas input and discharge gas treatment unit to be treated, and further, the experimental evidence of engineering feasibility, reliability and rationality is verified.
The dynamic gas distribution method generally adopts a flow controller to quantitatively mix multi-component gases according to a certain gas flow ratio so as to quantitatively prepare mixed gases.
For example, the patent application of the application No. 201410843871.X discloses a dynamic gas distribution instrument and a gas distribution method, which are designed to have the following defects that 1, a raw material gas passage and a dilution gas passage are directly connected with a mixing pipeline, when the pressure of one or more inlets of the raw material gas passage or the dilution gas passage is overlarge, the pressure of the other passages with lower pressure can be caused to flow back, the control precision of a flow controller is affected, and 2, if the dynamic gas distribution amount is overlarge, the problems of uneven gas mixing exist without being fully mixed by a special gas mixing mechanism.
For example, the patent application of application number 201610023780.0 discloses a dynamic gas distribution system and a gas distribution method, which have the following defects that 1, secondary gas mixing is needed for multi-component gas mixing, a first gas mixing cavity lacks effective gas mixing and analysis detection means, the gas components of the first mixing cavity are difficult to ensure to be fully and uniformly mixed before entering a second mixing cavity, and further the gas proportion of the secondary gas mixing is influenced, and 2, because of lacking good gas mixing means, pre-mixing gas treatment is needed, and great resource waste is caused for treating expensive and scarce raw material gas.
Therefore, in order to solve the above-mentioned problems, it is necessary to design an online preparation and supply demonstration system for multi-component deuterium-tritium fuel exhaust gas.
