Chinese scientists have completed construction of an experimental superconducting fusion reactor that will replicate the same energy generation process that fuels the sun, with tests to begin as early as next month, state media reported yesterday.
The Tokamak fusion device, built in Hefei, the capital of eastern China's Anhui Province, is a smaller version of the International Thermonuclear Experimental Reactor (ITER) to be built in southern France, which is not expected to be fully operational for a decade, the state-run newspaper China Daily reported.
Unlike conventional fission reactors, nuclear fusion produces no greenhouse gas emissions and only low levels of radioactive waste. Researchers hope it may eventually provide a cheaper, safer, cleaner and endless energy resource, reducing the world's dependence on fossil fuels and nuclear power.
China's reactor, known by the acronym EAST, for experimental advanced superconducting Tokamak, was built at the Institute of Plasma Physics, a research department of the Chinese Academy of Sciences, in Hefei.
Although about a dozen experimental Tokamak reactors are in operation worldwide, the technology is still under development. The newly built Chinese reactor is a further advancement on the design.
China has been eager to claim progress in the project, as well as other advanced technologies.
"Over the next 10 years, while ITER is being built, we can conduct preliminary research on EAST to facilitate the operation and exploitation of ITER in the future,'' the newspaper cited Minister of Science and Technology Xu Guanhua (
A staffer at the Institute of Plasma Physics, contacted by phone, refused comment on the project.
China is one of seven countries participating in the multination project to build the 10 billion euro (US$12.8 billion) ITER in Cadarache, southern France. Construction is due to begin next year.
Xu said the reactor in Hefei would replicate the fusion power of the sun, forcing deuterium and tritium atoms together at a temperature of 100 million degrees Celsius, with a fusion power of about 500 megawatts.
LANDMARK CASE: ‘Every night we were dragged to US soldiers and sexually abused. Every week we were forced to undergo venereal disease tests,’ a victim said More than 100 South Korean women who were forced to work as prostitutes for US soldiers stationed in the country have filed a landmark lawsuit accusing Washington of abuse, their lawyers said yesterday. Historians and activists say tens of thousands of South Korean women worked for state-sanctioned brothels from the 1950s to 1980s, serving US troops stationed in country to protect the South from North Korea. In 2022, South Korea’s top court ruled that the government had illegally “established, managed and operated” such brothels for the US military, ordering it to pay about 120 plaintiffs compensation. Last week, 117 victims
China on Monday announced its first ever sanctions against an individual Japanese lawmaker, targeting China-born Hei Seki for “spreading fallacies” on issues such as Taiwan, Hong Kong and disputed islands, prompting a protest from Tokyo. Beijing has an ongoing spat with Tokyo over islands in the East China Sea claimed by both countries, and considers foreign criticism on sensitive political topics to be acts of interference. Seki, a naturalised Japanese citizen, “spread false information, colluded with Japanese anti-China forces, and wantonly attacked and smeared China”, foreign ministry spokesman Lin Jian told reporters on Monday. “For his own selfish interests, (Seki)
Argentine President Javier Milei on Sunday vowed to “accelerate” his libertarian reforms after a crushing defeat in Buenos Aires provincial elections. The 54-year-old economist has slashed public spending, dismissed tens of thousands of public employees and led a major deregulation drive since taking office in December 2023. He acknowledged his party’s “clear defeat” by the center-left Peronist movement in the elections to the legislature of Buenos Aires province, the country’s economic powerhouse. A deflated-sounding Milei admitted to unspecified “mistakes” which he vowed to “correct,” but said he would not be swayed “one millimeter” from his reform agenda. “We will deepen and accelerate it,” he
Japan yesterday heralded the coming-of-age of Japanese Prince Hisahito with an elaborate ceremony at the Imperial Palace, where a succession crisis is brewing. The nephew of Japanese Emperor Naruhito, Hisahito received a black silk-and-lacquer crown at the ceremony, which marks the beginning of his royal adult life. “Thank you very much for bestowing the crown today at the coming-of-age ceremony,” Hisahito said. “I will fulfill my duties, being aware of my responsibilities as an adult member of the imperial family.” Although the emperor has a daughter — Princess Aiko — the 23-year-old has been sidelined by the royal family’s male-only
