The world's first commercial scale fusion reactor is scheduled to start operation in 2025, 35 countries including Japan cooperate

The International Thermonuclear Experimental Reactor (ITER) is an international experimental facility that aims to realize a fusion reactor that generates power using fusion reactions . 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.

On July 23, 2019, at the construction site of ITER in Cadarache , in southern France, a delivery ceremony was held for parts attended by senior officials from each country who cooperated. In addition to Japan, 35 countries including EU countries, the United States, Russia, China, Korea, and India participate in ITER, and a cooperative system is taken for the realization of a fusion reactor.

The fusion reactor aimed by ITER has the same advantages as nuclear power generation, such as low carbon dioxide emissions and lower high level radioactive waste emissions compared to nuclear power generation. Fusion power generation will reduce the need for fossil fuels, and it will be possible to supplement renewable energy generation where intermittent and unreliable issues are considered problematic.

Officials say ITER's fusion reactors will be more complex than any machine ever manufactured worldwide. ITER's fusion reactor uses a tokamak-type system, in which ultra-high temperature plasma is confined by a strong magnetic field generated by an electromagnet.

The temperature of the plasma reaches 150 million degrees Celsius, which is ten times higher than the center of the solar nucleus . In order to confine this plasma, the world's largest electromagnet is needed, and a huge furnace wall etc. which accommodates them will be needed further.

In ITER, in recent years, the base and lower cylinder etc of the cryostat which is an apparatus with the heat insulation structure for storing fusion are installed, and the construction is progressing steadily. ITER officials say, 'The ITER cryostat manufactured in India will be 16000 cubic meters,' 'The diameter and height are both about 30m and weighs 3850 tons. The cryostat is the base, lower cylinder, upper part It consists of four major sections: cylinder, upper pig. '

According to officials, the ITER project is 65% complete at the time of writing, and spokeswoman Sabina Griffith commented that the world's first commercial-scale fusion reactor project will begin operation in 2025. did. However, as of 2025, full-scale power generation will not start, and it will take another 10 years from 2025 to fully operate the facility using tritium .

The construction of ITER is expected to continue well, and important parts, poloidal field coils, will come from China with European contribution, vacuum containers from Korea, and toroidal field coils from Japan and Europe. Waiting for parts to arrive, full-scale assembly will begin in the spring of 2020.
