However, hydrogen isotope permeation behavior may change in fusion reactors compared to that in unirradiation environments since structural materials are exposed to severe radiation environments in fusion reactors..
At the same time, Eni has signed an agreement with MIT that will allow the company to jointly carry out research programs on plasma physics, fusion reactor technologies, and new generation electromagnetic technologies.
The military-industrial complex, for its part, has, by releasing patents on“UFO” technology, compact fusion reactors and other wonders, indicated that it is ready for a swords-to-plowshares transformation.
This will contribute to the proposal of highly reliable operation scenario and design of the fusion reactor. Further, this will contribute to the early achievement of the fusion reactor.
Metal-type materials were developed intensively in the 1960s. They are now used widely in devices that demand strong magnetic fields, including linear motor cars, fusion reactors and MRI diagnostic equipment.
The answer is extremely simple. If the material for the fusion reactor wall is to be composed entirely from one kind of material, then the mille-feuille pastry sedimentary layer structure will not be generated.
ITER has announced that it has steadily achieved a milestone for the operation of fusion reactors, and said that it is expected that the first operation of fusion reactors will take place in 2025 six and a half years later.
Further, in the fusion reactor the plasma is confined by the strong magnetic field. Because molten salt has high electrical resistivity, it has the characteristic of being difficult to decelerate even in the magnetic field.
The most important job in system design is deciding upon the size of the fusion reactor, the strength of the magnetic field, and the fundamental specifications of the electric power generation.
Although it is a nuclear fusion reactor, its attack capability is extremely high, and due to the rich energy supply, it has a lot of equipments of laser system.
強度の試験では、核融合炉条件を模擬して、800°Cの温度で材料に一定の負荷をかけ続けます。
In the strength test, in order to simulate the conditions of the fusion reactor, we heat the material to the high temperature of 800 degrees°C and set a fixed load.
However, complex extreme environment in the nuclear fusion reactor which overlaps with high temperature, high pressure, and radiation is a barrier to its realization.
Plasma experiments Plasma Physics and ControlIn order to realize a fusion reactor in a magnetically confined device, it is necessary to maintain a high temperature(~ one hundred million degree Celsius)and a high density(~1020 m-3) plasma for more than one second.
In the ceramics materials being examined for use in the fusion reactor are various materials. Those materials are required to be tested under an environment that may be expected in the reactor, and it is necessary to analyze that condition.
Applications which might gain more importance in the future are construction material for the tungsten alloy plasma technique in magneto hydrodynamic power generation(W and W-Cu) and target plates in fusion reactors W.
Looking at the complete fusion power plant, there will be numerous types of equipment not part of the fusion reactor structure, such as equipment for cooling the superconducting coils, equipment for generating power from the heat removed from the fusion reactor, equipment for refining the fuel, and equipment that performs maintenance.
In order to confine high-temperature plasma, we send a large electrical current through the superconducting coils that have been set near the plasma and generate a powerful magnetic field. In the LHD and in a fusion reactor the methods for sending an electrical current through the coils differ.
In the future, using the multi-layer simulation method we will reproduce a complete plasma of a nuclear fusion reactor through a supercomputer. Moving forward in promoting design research for the nuclear fusion power plant through predictions of its behavior is anticipated.
In the future, using the above-mentioned methods, we will aim at designing and manufacturing a divertor that is stable and operational for a long period by producing a large-scale divertor test device whose structure will be similar to that of the divertor to be utilized in the fusion reactor.
