Taking Yu Mu with him, Xu Chuan quickly rushed towards the entrance of the experimental reactor park.
At the entrance of the base, several special super-heavy trucks are parked there.
Xu Chuan quickly stepped forward and checked around these vehicles.
What is installed inside is indeed an ICFR heating antenna shipped from Luyang, and it is a complete set.
For the Daybreak Demonstration Reactor Project, after these ICRF heating antennas are modified, the adapted demonstration reactor is almost ready for use.
After all, the equipment itself is built according to the standards of the demonstration reactor project.
It was originally sold to ITER in exchange for a sum of funds and some technology, but China has now withdrawn from ITER, and it is impossible to sell these things to ITER again.
On the one hand, Europe probably won't buy it either. After all, buying Chinese equipment now is considered as funding the enemy on the road to controllable nuclear fusion.
On the other hand, even if they are bought from Europe, they will not be able to sell these ICRF antennas to ITER.
After all, compared to other Western countries, China is relatively far ahead in terms of microwave heating, and selling it is also considered an enemy.
"I never thought he would send this thing over."
On the side, Peng Hongxi, who also received the news, looked at the ICRF heating antennas in these super-heavy trucks with some emotion.
Xu Chuan was a little curious and asked: "Mr. Peng knows its specific performance parameters?"
Hearing this, Peng Hongxi nodded and said: "Actually, it is derived from the microwave heating antenna technology I designed before."
"After I retired, Chen Mingji led the people in Luyang to continue research on microwave heating technology. The technology is better than the technology. Today's ICRF antenna heating technology is also well-known in the world."
"As for the set in front of you, I really know its performance parameters. After it was first developed, Lao Chen showed me some information."
"This set of ICRF antenna heating equipment is designed to provide long pulse continuous wave heating for plasma for up to one hour, with a frequency range of 30~100MHz, a transmission line impedance of 50Ω, and a heating power of 1.5~3MW...
..."
"Aside from these conventional parameters, the most critical core point is that the vacuum feed port of this ICRF antenna device is a redesigned crank-shaped vacuum feed port, which can withstand ultra-high voltages up to 120KV or more."
Hearing this, Xu Chuan looked a little moved.
It has to be said that judging from the performance parameters stated by Academician Peng Hongxi, the performance of this ICRF heating antenna is quite powerful.
The ion cyclotron heating (ICRF) antenna is one of the most critical components of controllable nuclear fusion. It plays the role of igniting and raising the reactor chamber and maintaining the temperature in the reactor chamber.
In the ICRF heating antenna, the vacuum feed port is the core key point. On the one hand, it has to withstand extremely high current and voltage, and on the other hand, it also plays the role of isolating vacuum and hot nitrogen.
During the operation of the ICRF antenna, the voltage between the inner and outer conductors connected to the feed port can be as high as 45KV. Therefore, increasing the breakdown voltage of the feed port and reducing its dielectric loss is one of the key technologies in feed port design.
Moreover, improving the voltage resistance of the feed port can reduce the occurrence of spark events and effectively improve the safety of the ICRF antenna and even the overall device.
The ability to withstand 120KV can be described as a real black technology.
You must know that most countries that are capable of researching controllable nuclear fusion have manufactured vacuum feeders with a voltage tolerance of around 50KV. But the one in front of you has more than doubled that.
Chen Mingji sent him this set of equipment, which was really a great gift.
Not only did it save him the time to build it himself, it was also better.
...
After arranging for engineers to move the equipment into the engineering base, Xu Chuan and Peng Hongxi returned to the office.
After making a pot of tea, the two of them had a rare moment of leisure.
When talking about the Luyang EAST fusion device and hearing that Chen Mingji had resigned from all his positions and left the field of controllable nuclear fusion, Peng Hongxi also sighed.
"To be honest, Lao Chen's abilities are quite good, otherwise he would not have brought the EAST device to the top three in the world in terms of tokamak devices in recent years. The development in Luyang is actually quite good in his hands.
Yes, but after encountering a monster like you, the progress seems a bit slow."
"If he can stay and continue to study some problems with the engineers in Luyang, I believe he can still make some results."
Xu Chuan smiled, took a sip from the teacup, and said, "Everyone has their own choice, just do whatever you want."
After a pause, he continued: "After he talked to me for a while some time ago, I can understand his decision now."
"I have been in control of Luyang's controllable nuclear fusion project and have been the leader for so long. If I ask him to come to my side now to assist me in achieving controllable nuclear fusion, I'm afraid I can't do it."
"Moreover, for the field of controlled nuclear fusion in China, even if I make these results with Dawn, I may not be able to convince everyone. After all, there is no real controllable nuclear fusion technology."
"He was sitting there, maybe someone was holding a tiger skin and setting up a big flag. In that position, he was sitting on a fire and roasting."
"He probably wants to use his retirement to allow me to completely take over the banner of domestic controllable nuclear fusion. For him, like us, he is a person who is obsessed with the realization of controllable nuclear fusion technology."
"Although we have had some misunderstandings due to some differences in concepts, they are not a big deal."
Hearing this, Peng Hongxi sighed and said softly: "I just feel it is a pity. The hope of controllable nuclear fusion technology is right in front of us, so what if we can hold on for a while longer?"
"Decades of ups and downs have gone through, so why retire now?"
Xu Chuan thought for a while and said: "Probably because he has always held on to this dream and hopes to see the realization of controllable nuclear fusion, he chose to retire."
This chapter is not over yet, please click on the next page to continue reading! Hearing this, Peng Hongxi did not speak anymore, but there was some regret on his face.
This is probably the most appropriate way.
But from his perspective, it's a little different.
After all, the two have worked together for so many years.
For him, another colleague who has been through ups and downs and has been struggling since the founding of the People's Republic of China has left this field.
Although the other party deviated from the track midway due to arrogance or ideas in his heart, in the end, he used his departure to return the track to the right path.
"By the way, regarding the issues of tritium self-sustainment and tritium retention, I have designed a set of plans here these days. Mr. Peng, would you like to take a look?"
After drinking a cup of tea, Xu Chuan stood up, took out a stack of manuscript paper from the drawer, and handed it over.
Seeing that the conversation was about business, Peng Hongxi also put down the tea cup in his hand, took the manuscript paper with a serious look, and started to read through it.
After waiting for about ten minutes, he put down the manuscript, looked at Xu Chuan with shining eyes and asked: "Lead-lithium mixture molten salt technology? It's interesting. How did you come up with this?"
In controllable nuclear fusion technology, tritium self-sustainment is a systemic problem, but tritium self-sustainment is also a key issue in maintaining reactor operation.
Since the 14 MeV fusion neutrons and transmutation products hydrogen and helium produced during the operation of the fusion reactor will produce various defects in the tritium breeder, these defects will affect the penetration and retention behavior of tritium, so the transport of tritium in the breeder is a
Very complex process.
Currently, in the research process of controllable nuclear fusion in various countries, there are generally two routes for tritium self-sustaining technology.
There are two types: solid proliferator and liquid proliferator.
From the name, you can understand it.
The solid multiplier is made of high-temperature resistant ceramic balls made of lithium silicate, lithium titanate, lithium zirconate, lithium oxide and other materials, and then placed in the cladding of the first wall, and then tritium is generated through high-energy neutron impact.
When working, the 14 MeV high-energy neutrons produced by the deuterium-tritium fusion reaction will react with the lithium in the pellet to generate tritium, and then the generated tritium will be extracted by purging helium gas at a suitable temperature.
The disadvantage is that due to the low lithium mass fraction of the solid tritium multiplier, the tritium multiplication ability is not high, and a high-cost neutron multiplier needs to be specially arranged.
This is its main disadvantage.
The liquid multiplication agent uses liquid metal containing lithium, such as lead lithium LiPb, lithium Li or molten salt such as fluorine lithium beryllium FLiBe, etc. as the multiplication material.
Compared with solid proliferators, liquid proliferators have many advantages.
For example, the tritium value-added capacity is high, the liquid lithium Li atom content is high, and the multiplier itself contains neutron multiplier elements such as lead, Pb, and beryllium Be, so there is no need to add a neutron multiplier.
Or the complex geometry and adaptability, after all, is liquid and can fill every cladding without the need for complicated machining processes.
Or there is no life limit, and liquid materials can be exported at any time for flow replacement without shutting down, etc.
However, liquid lithium materials also have huge flaws in the tritium self-sustaining process.
In a magnetic confinement fusion reactor, high-temperature plasma is confined by a high-intensity magnetic field.
The strong magnetic field not only constrains the plasma, but also has a negative impact - causing the magnetohydrodynamic (MHD) effect.
When a conductive fluid moves in a magnetic field, it will generate an induced electromotive force, which in turn will generate an induced current. The interaction between the induced current and the magnetic field will produce a volume force in the opposite direction, the Lorentz force, which will hinder the movement of the fluid, that is, the MHD effect will occur.
The generation of MHD effect not only seriously affects the flow characteristics of liquid metal, but also greatly increases the corrosion problem of structural materials.
In addition, it will also cause changes in turbulent flow characteristics, suppressing turbulence and affecting fluid heat transfer performance.
If these problems are not solved, the problems caused by the MHD effect of liquid lithium will cause great harm to the development of the liquid cladding of the fusion reactor and the safety of the entire fusion reactor system.
In this regard, its usability is far less than that of a solid-state breeding cycle.
Therefore, at Dawn Research Institute, although there are two research routes for solid-state and liquid-state lithium proliferation, the main direction is still focused on solid-state proliferation.
Because it is safe, it will not affect the controllable fusion reactor.
However, in the manuscript papers handed over by Xu Chuan, he saw the hope of solving the problem of tritium multiplication in liquid lithium.
