China will heat by artificial sun with nuclear fusion

We all know about China with its coldness and horrible frost in winter. So the government of this country has joined scientists to build a solution. And now they have become the first country in the world to attain the conditions necessary for the implementation of nuclear fusion, but according to the newspaper, this is the ' holy grail' of renewable energy. create.

The reactor was installed in Hefei City (Hefei) in Anhui Province, about 400km west of Shanghai.

This reactor is responsible for the implementation of the experiments under the ITER project , a huge international project being carried out in southeastern France to control the integration of atoms.

In 2017, this Chinese machine broke the world record for maintaining the conditions necessary for the nuclear nuclear synthesis process and by the end of 2018 it once again broke the record of yourself by reaching a temperature of 100 million degrees, 6 times more than the central heat generated by the Sun and the time to maintain this temperature is 100 seconds, a considerable time.

The superconductor used in a reactor called Tokamak is an advanced test, better known for its short name EAST. Tokamak is the original designed magnetic compression chamber from the Soviet Union to produce a significant amount of heat to melt atomic nuclei.

This 'fused' nuclear reaction should not be confused (the principle used for the H bomb explosion) with the 'fission' nuclear reaction (atomic division) used in nuclear power plants. normal multiplication.

Nuclear fusion is considered to be the energy of the future because it is infinite, like the sun, and does not produce waste or greenhouse gases. Song Yuntao, a leader of the experimental reactor project, said: 'With this reactor, we hope China will contribute much to the use of nuclear synthesis of humanity.'

However, the challenge for the reactor is to have a special heat-resistant material storage tank and maintain this temperature in a sustainable manner. And the cost for this is not small: more than 12 years after the start of the project, ITER's budget has been worth nearly 20 billion euros.

At Hefei, the reactor is in the center of a concrete structure, connected by cables and pipes to a bunch of measuring devices and other devices, which look like a giant bicycle wheel.

In fact, research on nuclear fusion is not new. According to ITER, the Jet project in the UK so far is the largest and strongest Tokamak ever built.

Other magnetic compression chambers, some of which are now shut down, have been built in Europe, the US, Japan and South Korea, with better overall results than EAST.

According to Wu Songtao, EAST only reached 100 million degrees at the center, not at the lower temperature range, these parameters are still far from what ITER expected.

Currently, the reactor built in Saint-Paul-lès-Durance, southeast of France, will be ten times larger than its predecessor and will reach 150 million degrees. However, it must wait until 2025 to have the first tests.

Going back to the nuclear reactor in Hefei, China's ambition is to build another nuclear fusion reactor, unlike the EAST, which will be connected to the national grid, providing electricity for living. for people, especially for winter heating.

According to Chinese scientists, the reactor will be completed by 2030 and may start to supply electricity between 2040-2050. The budget is planned for this post-ITER period of 6 billion. Yuan (800 million euros).

Scientists also frankly claim to have the advantage of 'standing on the shoulders of ITER giants' , but nonetheless, these also prove China's scientific progress.

1. China will complete the second "artificial sun" this year
2. China can successfully build the artificial Sun.
