The situation in China of the International Experimental Thermonuclear Reactor ITER program

It was proposed in 1985 by the Soviet Union, the United States, Japan and the European Community.

The aim is to build the first experimental fusion reactor, and in 2006 the seven parties (the European Union, China, South Korea, Russia, Japan, India and the United States) formally signed a joint implementation agreement to start the implementation plan. The plan will last 35 years, including 10 years in the construction phase, 20 years in the operation and development phase, and 5 years in the deactivation phase.

The project integrates the main scientific and technological achievements of international controlled magnetic confinement nuclear fusion research, and has a reliable scientific basis and a solid technical foundation. It is an essential step towards the commercialization of fusion energy, with the goal of verifying the scientific and technical feasibility of peacefully exploiting fusion energy. With a total investment of more than US$10 billion, the project is the largest international science and technology cooperation project outside the International Space Station.

The International Experimental Thermonuclear Fusion Reactor is commonly known as the artificial sun.

The International Thermonuclear Experimental Reactor (ITER) is one of the world's largest and most far-reaching international research cooperation projects, taking about 10 years to build and costing US$5 billion (1998 values). The ITER device is a coarse-down superconducting tokmak capable of producing large-scale nuclear fusion reactions, commonly known as artificial sun. The ITER device is mainly composed of magnet, vacuum chamber, cladding, deflector, cryostat, heating and current drive system, tritium value-added system, CODAC system, diagnostic system, cryogenic system, water cooling system, fuel system, power supply system, and remote control system.

At 21:00 on April 12, 2023, the world's first fully superconducting tokamak East device in operation achieved significant results, achieving high-power and stable 403-second steady-state long-pulse high-confinement mode plasma operation, creating a new world record for tokamak steady-state high-confinement mode operation.

Introduction to Nuclear Fusion:

Nuclear fusion is a form of nuclear reaction in which two lighter nuclei are combined to form a heavier nucleus and a very light nucleus (or granular nucleus).

Although the two lighter nuclei repel each other because they are both positively charged when they fuse, two nuclei with high enough energy meet head-on, and they can be gathered together quite closely so that the nuclear force can overcome the Coulomb repulsion force and cause a nuclear reaction. At 1:03 a.m. local time on December 5, 2022, Lawrence Livermore National Laboratory used 192 powerful laser beams to hit a solid target of a hydrogen isotope the size of a pepper.

It is the largest and most far-reaching international scientific project in the world today. It aims to simulate the nuclear fusion process in which the sun glows and heats, and explore the commercial feasibility of controlled nuclear fusion technology.

It is one of the world's largest and most far-reaching international research cooperation projects, taking about 10 years to build and costing $5 billion. The ITER device is a superconducting tokmak capable of producing large-scale nuclear fusion reactions, commonly known as artificial sun.

Human beings can enter the first-level cosmic civilization, that is, they can use the energy of the entire earth, and it doesn't matter if the cost of power generation is larger, half of the world's population can use fusion electricity, which can solve the world's energy problem of oil depletion.

It is an experimental project that many countries have engaged in together, established in France, with the aim of commercializing nuclear fusion, that is, nuclear fusion can be used to generate electricity, which has not yet been completed.

The International Thermonuclear Experimental Reactor (ITER) program is currently one of the world's largest and most far-reaching international scientific research cooperation projects, taking about 10 years to build and costing US$5 billion (1998 values). The ITER device is a superconducting tokmak capable of producing large-scale nuclear fusion reactions, commonly known as artificial sun. In January 2003, China approved China's participation in the ITER plan negotiations, and in May 2006, with the approval of China, China's ITER Negotiation Joint Group initialled the ITER plan agreement with the European Union, India, Japan, South Korea, Russia and the United States on behalf of China.

These seven parties include the world's major nuclear states and major Asian countries, covering nearly half of the world's population. Our participation in the ITER program is based on the basic needs of energy in the long term. On January 5, 2013, the Hefei Institute of Physical Sciences, Chinese Academy of Sciences announced that the neutral beam injection system of the "artificial sun" experimental device assisted heating project successfully achieved 100 seconds long pulse hydrogen neutral beam extraction on the comprehensive test platform.
