China’s $1 trillion ‘artificial sun’ fusion reactor just got five times hotter than the sun

Posted by in categories: nuclear energy, physics

The Chinese experimental nuclear fusion reactor smashed the previous record, set by France’s Tore Supra tokamak in 2003, where plasma in a coiling loop remained at similar temperatures for 390 seconds. EAST had previously set another record in May 2021 by running for 101 seconds at an unprecedented 216 million F (120 million C). The core of the actual sun, by contrast, reaches temperatures of around 27 million F (15 million C).

“The recent operation lays a solid scientific and experimental foundation towards the running of a fusion reactor,” experiment leader Gong Xianzu, a researcher at the Institute of Plasma Physics of the Chinese Academy of Sciences, said in a statement.

China has achieved a new world record in its development of a “man-made sun”, a fusion energy reactor. Scientists managed to sustain the reactor, at the extreme temperature of 70 million degrees Celsius for 1,056 seconds. In May, scientists also made a breakthrough, when they were able to achieve a plasma temperature of 120 million degrees Celsius for 101 seconds. China’s development of an “artificial” sun is part of its mission to find solutions to create limitless clean energy.

China, US, UK, France and Russia pledge to avoid nuclear war

Posted by in categories: existential risks, military, nuclear energy

😀


Five of the world’s largest nuclear powers pledged on Monday to work together toward “a world without nuclear weapons” in a rare statement of unity amid rising East-West tensions.

“A nuclear war cannot be won and must never be fought,” said the joint statement, which was issued simultaneously by the United States, Russia, China, the United Kingdom and France. “As nuclear use would have far-reaching consequences, we also affirm that nuclear weapons — for as long as they continue to exist — should serve defensive purposes, deter aggression, and prevent war.”

China’s ‘Artificial Sun’ Has Just Hit a New Nuclear Fusion Milestone

Posted by in category: nuclear energy

China’s “artificial sun”, a nuclear fusion tokamak reactor that could provide almost limitless amounts of emission-free energy, set a new record on Thursday by running for 1,056 seconds at high plasma temperature, according to a report from Xinhua.

The particular tokamak reactor is called EAST, which stands for Experimental Advanced Superconducting Tokamak. It is located in Hefei, China, and it also broke a record in May when i… See more.

Europe’s power crunch shuts down factories as prices hit record

Posted by in category: nuclear energy

The crunch is so severe that it’s forcing factories to curb output or shut down altogether. Aluminium Dunkerque Industries France has curbed production in the past two weeks due to high power prices, while Trafigura’s Nyrstar will pause production at its zinc smelter in France in the first week of January. Romanian fertilizer producer Azomures temporarily halted output.

Electricite de France SA said last week it would halt four reactors accounting for 10 per cent of the nation’s nuclear capacity, straining power grids already facing cold weather. At the beginning of January, 30 per cent of France’s nuclear capacity will be offline, increasing the reliance on gas, coal and even oil.

Tokamak Energy Has Just Made a Breakthrough in Nuclear Fusion

Posted by in categories: innovation, nuclear energy

Magnets could be the ‘secret sauce’ required for viable nuclear fusion.

Tokamak Energy, a company working on nuclear fusion technology, has recently announced a major breakthrough in its research and development. Testing of its cryogenic power electronic technology for its superconducting magnet’s high-efficiency operation was, by all accounts, a big success.

The company’s bid to provide the world with near-limitless energy uses a combination of spherical tokamaks and high-temperature superconducting (HTS) magnets. According to reports, tests of the new power electronics showed twice the efficiency of previous systems.
