China hits nuclear fusion milestone



Chinese scientists have reached an important milestone in the global quest to harness energy from nuclear fusion.

The team of scientists from China's Institute of Plasma Physics announced this week that plasma in their Experimental Advanced Superconducting Tokamak (EAST) – dubbed the "artificial sun" – reached a whopping 100 million degrees centigrade, temperature required to maintain a fusion reaction that produces more power than it takes to run.

To put that in perspective, The temperature at the core of the sun is about 15 million degrees Celsius, making the plasma in China's "artificial sun" more than six times hotter than the original.

The news comes after China shocked the science community last month with plans to launch "artificial moon" by 2020.

Speaking to the ABC, associate professor Matthew Hole from the Australian National University said it was "a step in the right direction for nuclear fusion science."

"It's certainly a significant step for China's nuclear fusion program and important global development," Dr Hole said

Energy production, with zero greenhouse gas emissions and no long-life radioactive waste.

"It provides a silver bullet energy solution … providing that one can harness it. "

He added that nuclear fusion reactors, and thus avoidance associated with the currently used nuclear reactor reactors, which may be considered to be dangerous weapons and are prone to possible catastrophic meltdowns. 1

"There is nothing China can not make," one user on We ibo said.

Another proclaimed that "if this technology is put into use, the world will no longer feel anxious about the energy crisis."

So how did China manage to pull it off?

While current nuclear

One way of achieving this on earth is by using what's known as a tokamak,

Powerful magnets lining the inner walls of EAST then take the plasma to a tiny area to maximize the chance that the ions will fuse together.

The Chinese research team said they were able to achieve the record temperature through

The latest breakthrough provided experimental evidence that reaching the 100 mill ion degrees Celsius is possible, according to China's Institute of Plasma Physics.

It is said that the energy possibilities of nuclear fusion have attracted large investment from countries all over the world – including China – Australia has lagged behind.

"As a nation, Australia is about to loose its capability in fusion," said Dr Smith said .

Australia said that it has just become a major investment in this space, but it has just been neglected in recent years. "

science: the International Thermonuclear Experimental Reactor (ITER).

ITER is set to be the first fusion of the United States [0005] As EAST has a similar design to ITER but on a smaller scale, it is likely to become an important testing device during the development of ITER to China's Institute of Plasma Physics.

ITER is ready to begin its first plasma and begin operations in 2025.
