HEFEI -- The experimental advanced superconducting tokamak (EAST), or the Chinese "artificial sun", has achieved a continuous high-temperature plasma operation for 1,056 seconds in the latest experiment on Thursday, the longest time of operation of its kind in the world.

The breakthrough was announced on Friday by Gong Xianzu, a researcher at the Institute of Plasma Physics of the Chinese Academy of Sciences (ASIPP), who is in charge of the experiment conducted in Hefei, capital of east China's Anhui Province.

"We achieved a plasma temperature of 120 million degrees Celsius for 101 seconds in an experiment in the first half of 2021. This time, steady-state plasma operation was sustained for 1,056 seconds at a temperature close to 70 million degrees Celsius, laying a solid scientific and experimental foundation toward the running of a fusion reactor," said Gong.

The ultimate goal of EAST, located at ASIPP in Hefei, is to create nuclear fusion like the Sun, using deuterium abound in the sea to provide a steady stream of clean energy.

As opposed to fossil fuels such as coal, oil, and natural gas, which are in danger of being exhausted and pose a threat to the environment, raw materials required for the "artificial sun" are almost unlimited on earth. Therefore, fusion energy is considered the ideal "ultimate energy" for the future of humanity.

Now EAST has reached all three targets separately – 1-million-ampere current, 1,000-second duration and 100-million-degree-Celsius temperature. The final mission for the tokamak is to reach all the targets in one try.

China's 'artificial sun' smashes 1000-second fusion world record

China's 'artificial sun' set a new world record on Thursday by running for 1056 seconds at high plasma temperature, the longest duration for an experimental advanced superconducting tokamak (EAST) fusion energy reactor, Xinhua News Agency reported.

【my country’s second Hualong No. 1 nuclear power unit issued its first degree of electricity】

At 22:35:38 on January 1, my country’s independent third-generation nuclear power "Hualong One" ushered in a new year "good start": China National Nuclear Corporation's Fuqing Nuclear Power Unit 6 was successfully connected to the grid for the first time and began to send the first kilowatt-hour of electricity to the grid, becoming the world The third and my country's second "Hualong No. 1" grid-connected generator set.

"Hualong One" is one of the most widely accepted three-generation nuclear motors in the current nuclear power market. Each "Hualong No. 1" unit has an annual power generation capacity of nearly 10 billion kWh, which can meet the annual production and domestic electricity needs of 1 million people in moderately developed countries; at the same time, it is equivalent to reducing standard coal consumption by 3.12 million tons and reducing carbon dioxide emissions by 8.16 million. Tons, equivalent to more than 70 million trees for afforestation. (Reporters Lin Shanchuan and Zhang Huaying)

On October 24, the world's first land-based commercial small modular reactor - Linglong-1 steel containment vessel bottom bulkhead was hoisted ahead of schedule. This is an important milestone in the construction of CNNC’s Hainan Changjiang multi-purpose small modular reactor technology demonstration project, laying a solid foundation for the subsequent construction of the main structure of the reactor plant

NPC deputy: China masters 4th-generation nuclear technology

China has mastered the fourth-generation nuclear technology, and the world's first nuclear power plant using the technology has been connected to the national grid, Dong Baotong, vice chairman of the China Atomic Energy Authority and deputy to the 13th National People's Congress (NPC), told China Media Group.

China's homegrown high-temperature reactor is considered one of the safest as it will not melt under duress and carries no risk of radiation leakage, according to the China National Nuclear Corporation.

The plant, located in east China's Shandong Province, entered operation in December. With 93.4 percent of material domestically sourced, the plant can meet the heat source demand in ethanol purification, petrochemical and hydrogen production, and other fields.

"The greatest benefit of the high-temperature gas reactor is its inherent safety feature," Dong said. "It doesn't need a big building or a thick containment vessel like other nuclear reactors."

The NPC deputy said that in addition to generating electricity, nuclear technology will also be increasingly used in major projects in the aerospace industry to provide power support for spacecraft carrying out deep space exploration missions.

"Our Chang'e lunar missions can rely on solar power because they are within the solar system. Solar power can assist in Mars missions as well," he said. "But if our spacecraft are exploring the deep space where there is no solar power in the future, then nuclear power will almost be the only choice."

The construction of China's self-developed third-generation nuclear technology, Hualong One, is making steady progress. Four units at home and abroad have been connected to the grid and are generating electricity – two each in southeast China's Fujian Province and Pakistan.

China's home-grown fourth-generation nuclear technology, the high-temperature gas reactor, is considered one of the safest types of nuclear reactors. It will not melt when placed under duress and there is no risk of radiation leaks.
