In mid-June, a little faster than the original plan, the China National Nuclear Industry Construction Group used several times the manpower and three shifts to fill in the construction. The overall construction of the Qixia Controlled Nuclear Fusion Project was finally completed.
Although it is still a long way from being completely perfected, at least now, with the controllable fusion reactor in place, it can officially begin experiments.
Xu Chuan wore formal attire and personally hosted the completion ribbon-cutting ceremony, and saw those pairs of eyes that revealed hope and expectation.
That is the desire for the strength of the motherland, and the hope and expectation for the completion of controllable nuclear fusion technology.
.......
In early July, after going through ups and downs, a long march of thousands of miles, and spanning a full three months, the disassembled and packed ASDEX device officially arrived at the Yangtze River port of Jinling from the Germanic country.
Three hundred million euros, based on the current exchange rate, is a full 2.4 billion RMB.
Even for a controllable nuclear fusion project, this is a quite large number.
But Xu Chuan knew it was worth it. Although the ASDEX device has been retired for two years, its performance parameters are still quite powerful when compared to the entire world.
Especially regarding the water-cooled divertor, although the Germanic country has updated it, no other country can beat the water-cooled divertor deployed on it.
In addition, there are the long-term upgrades and transformations of the Planck Plasma Institute, as well as matching and adapting equipment, etc. It is not an exaggeration to say that it has cost more than one billion euros.
Calculating it this way, the exchange of 300 million euros for high-temperature copper-carbon-silver composite superconducting material technology for this complete equipment is actually a huge advantage.
If the Planck Plasma Institute hadn't urgently needed to prove its strength in the stellarator and obtain more financial support, I'm afraid it would not have been so easy to complete this deal.
........
With the support and coordination of the Jinling government, the transported ASDEX device was successfully delivered to the Qixia Mountain Controlled Nuclear Fusion Engineering Base and placed in the core area.
Immediately, with the assistance of engineers from the Planck Institute of Plasma Research, the dismantled parts and equipment were quickly reassembled.
After the equipment arrived in China and was delivered to the project base, the ASDEX device was officially renamed the "Daybreak" device, and its English name was the "DAWN" device.
The name was given by Xu Chuan, which means that it will break through the dark clouds over controllable nuclear fusion technology like the dawn. He has great hopes for the dawn-breaking device.
With the delivery of the fusion reactor device, Qixia's controllable nuclear fusion project has officially entered the next stage.
Regarding controllable nuclear fusion technology, Xu Chuan currently has three big pieces of the puzzle in his hands.
The first and most important piece of the puzzle is naturally the mathematical control model of 'plasma turbulence', which is one of the cores of the entire controllable nuclear fusion technology.
Only by controlling the high-temperature and high-pressure plasma in the controllable nuclear fusion reactor chamber and allowing it to run stably in the chamber can we successfully produce a steady stream of electrical energy.
The second piece of the puzzle is the high-temperature copper-carbon-silver composite superconducting material, which can provide a stable and powerful magnetic field to restrain the plasma flow in the fusion reactor chamber.
The powerful performance of high-temperature copper-carbon-silver composite superconducting materials can more than double the constraint performance of the original ASDEX device.
A strong magnetic field can more stably maintain the stability of the plasma in the chamber.
Especially after he and Zhang Pingxiang, two academicians, optimized it at the end of last year and adopted graphene whisker (fiber) toughening technology, the toughened side has better thermal conductivity.
This can better maintain superconducting materials below the superconducting critical temperature.
You must know that when the current passes through a conductor, the greater the intensity, the greater the magnetic field, and the higher the temperature generated at any time.
When the temperature exceeds the critical Tc temperature of the superconducting material, it will cause the superconducting material to reverse from the superconducting state to the normal state, thereby losing the superconducting performance.
Because how to stably maintain the temperature of the superconducting material below the Tc critical temperature while providing a strong magnetic field is also a headache.
The value of the thermal conductivity of high-temperature superconducting materials lies here. The better the thermal conductivity, the smaller the area that needs to contact liquid nitrogen and liquid helium to dissipate heat and reduce the temperature.
Compared with the copper-carbon-silver composite material before optimization, after optimization using graphene whisker (fiber) toughening technology, its thermal conductivity has nearly doubled.
This is reflected in the transformation of controllable nuclear fusion reactors, which can save at least more than one-third of the condensation area.
As for the third puzzle, it is the detection technology of plasma turbulence in the controllable nuclear fusion reactor chamber.
Of course, this technology is still in a theoretical state at present, and it is necessary to wait for the Dawn Device to be assembled before conducting experiments.
However, in the first half of this year, Xu Chuan theoretically established a complete theoretical route for this technology, and it can only be tested after the Dawn Device is completed.
.......
While the ‘Breaking Dawn’ fusion reactor was being assembled and renovated, on the other side, on Luyang Science Island, Chen Mingji, the general manager of the EAST project, was holding a tablet in his hand.
A piece of news is displayed above.
"The Planck Institute for Plasma Research and China Complete the Transaction of the ASDEX Device"
The news was delayed. After the ASDEX device had been delivered to the Qixia Mountain Controlled Nuclear Fusion Engineering Base, the transaction between the two parties was officially reported by some media in the nuclear energy field.
Of course, this is also what Xu Chuan requested.
He is worried that he may encounter some other setbacks and pressure before the transaction is completed.
For example, the European Union and NATO may intervene to block the deal after hearing about it.
For Xu Chuan and the Planck Institute for Plasma Research, this may be a happy deal, but for others, it may not be.
After all, China is now at the forefront of the world in the field of controllable nuclear fusion. If it obtains some technical support from the Planck Institute of Plasma Research, it may be completely transformed.
In addition to Western countries such as the European Union and the United States, not everyone is happy at home.
For example, the two people in this office couldn't be happier.
After rejecting Peng Hongxi's request last time, Chen Mingji was preparing to turn on the EAST device again and refresh the Tokamak's operating record as a sign of showing his superiors that the Luyang Controlled Nuclear Fusion Project he led had just
It is the most promising and possible route to realize controllable nuclear fusion engineering.
Including not renting the EAST device to Peng Hongxi, there are also some such thoughts in it.
After all, currently the only EAST device in China can conduct ignition operation experiments. Without EAST, even if you, Xu Chuan, are a Nobel Prize winner, you cannot conduct experiments out of thin air, right?
And if you make it yourself, even if you hurry up, it won't be completed in less than two or three years.
After two or three years, EAST will achieve greater results. One step at a time, one step at a time. He is prepared to keep suppressing the opponent and control the voice in the field of domestic controllable nuclear fusion.
But what I didn't expect was that that person actually didn't follow the routine and bought a piece of equipment directly from the Germanic country.
This was something he didn't expect.
More importantly, the Planck Institute for Plasma Research actually agreed to this transaction request, which is even more incredible.
You must know that he personally flew to Germany before and wanted to exchange the domestic advanced ICRF heating technology for water-cooled divertor technology, but was rejected without hesitation.
But Professor Xu directly traded the entire ASDEX device.
Thinking of this, Chen Mingji felt even more disgusted.
On the other side, the assistant who sent the news clicked his tongue and said with an expression of envy or jealousy on his face:
"Academician Xu is so generous. 300 million euros, 2.4 billion and nearly 2.5 billion RMB, just poured in."
Putting down the tablet in his hand, Chen Mingji said expressionlessly: "It's not his own money, so why not be generous?"
The assistant smiled and said, "That's right. Don't feel sorry for me. The country's funds have been squandered like this. Two and a half billion, this is not a small amount of money."
As a public official, to be honest, such words should not be said, or they are inappropriate.
Not to mention that China still took advantage of this transaction, but what was lost was Xu Chuan's own technology. Even if the transaction suffered a slight loss, it was actually so-called.
After all, the ASDEX device also comes with more advanced water-cooled divertor and other technologies from the Planck Institute of Plasma Research.
It can obviously make up for China's shortcomings in controllable nuclear fusion technology.
But in this office with only two people, it doesn't matter.
After all, there are no outsiders.
Chen Mingji didn't speak after hearing this.
After thinking for a while, he slowly said: "Since the other party bought the ASDEX device back, he will definitely not put it there. Let's check when he will start the ignition operation experiment, and we will be ready to start the operation experiment simultaneously."
Hearing this, the assistant's eyes lit up and he said happily: "When the experimental results are compared, we will naturally know which one is better."
"If we break the world record by then, he can't even light a fire. It would be a big shame."
"And even if it can be ignited and run, the old ASDEX device will definitely not be able to run for long! I believe the country will see it."
"At that time, we will still have the final say in the field of controllable nuclear fusion!"
Behind the desk, Chen Mingji said nothing, but the slight curve of his mouth proved that he recognized what his assistant said.
Even if an old ASDEX device can barely ignite for experiments, how long can it run?
