After China, Korea also overtakes Europe and ITER et cie and our "official researchers" shake me the slack:

Korea's fusion reactor sets new record

Scientists at the Korea Institute of Fusion Energy, where the nuclear reactor known as the KSTAR (Korea Superconducting Tokamak Advanced Research) experiment is located, announce that they have managed to maintain a plasma at 100 million degrees for 30 seconds . This very high temperature plasma stability indicates that we may be close to a viable fusion reactor.

Nuclear fusion appears to be one of the most promising technologies for an energy future without greenhouse gas emissions. As a "clean", safe (no risk of reaction runaway) and sustainable energy (the fuels required are almost unlimited), nuclear fusion energy could truly revolutionize the sector and contribute positively to the fight against climate change. Nevertheless, it is not so simple to recreate on Earth the reaction that takes place in the heart of the stars…

Despite decades of research, even the most modern installations struggle to maintain ionized matter at a temperature above 100 million degrees for several tens of seconds – the sine qua none condition for the fusion reaction to take place and produce energy. 'energy. The KSTAR experiment team announces that they have achieved a new breakthrough in this field: "Thanks to abundant fast ions stabilizing the turbulence of the central plasma, we generate plasmas at a temperature of 100 million kelvins that last up to 20 seconds without instability of the edges of the plasma or accumulation of impurities”, summarize the researchers in Nature.
Manipulate the magnetic field to increase stability

these nuclear handymen are crazy and naive! : Evil:
they are like kids playing with matches and big firecrackers.

indeed it is impressive, on a small Tokamak even more so.

But we are far from the commercial reactor... : Shock:

earlier this month, China made a surprise announcement. The country intends to master nuclear fusion by the end of the decade.

Hybrid power plant
On September 9, Professor Peng Xianjue from the Chinese Academy of Engineering Physics assured that the Chinese government had approved the construction of the world's largest pulsed power station in Chengdu, central-western province of Sichuan. , reports the Eurasian Times.It would be a hybrid plant that mixes nuclear fission and fusion.

The fusion energy produced by this installation would in fact not be used directly to supply the electricity network: it would be channeled to create a flow of fast particles which would strike the uranium, the fuel of the "fission" part of the power plant. .

A technique, different from that chosen by Westerners, which could allow China to achieve a viable system much more quickly. The Chinese authorities are counting on technical mastery from 2028. For commercial use planned for 2035.

use fusion neutrons to fission, we haven't finished having radioactive waste.

beforehand I don't really understand the interest because fissions generate quite enough neutrons (and even too many!). But the fusion neutron flux can modulate the operation of the fission reactor.

it looks complicated!

ah that would be an intermittent/repeating merge method.

the 2 candidate fusion initiation techniques are lasers and magnetic compression.

A breakthrough to put into perspective : Mrgreen:
The scientists thus produced about 3,15 megajoules of energy, originally delivering 2,05 megajoules via the lasers, according to the statement.

However, 300 megajoules of energy drawn from the electricity grid were required to activate the lasers -- making the operation overall still loss-making. But according to scientists, it will ultimately be possible to overcome this problem.
