Great Country Academician

In mid-June, Xu Chuan came to Luyang Science Island in person.

At present, the controllable nuclear fusion demonstration reactor project is advancing steadily and orderly. Whether it is the site of the Lixiao demonstration reactor project or the Lixiao Research Institute, it is a scene in full swing.

As for Xu Chuan, there was only one last problem that he needed to solve.

Namely, the last hurdle of systematic perfection, lithium neutron tritium proliferation.

In the period when the dawn fusion device needs to conduct various experiments, only the EAST device can be responsible for deuterium-tritium ignition and neutron irradiation experiments in China.

After nearly two months of renovation, today's EAST has a brand new look.

The original niobium-titanium alloy outer field coil superconducting material has been completely replaced with high-temperature copper-carbon-silver composite material produced by Western Superconducting Group.

The control system has also been fully replaced with the plasma turbulence numerical control model written by Xu Chuan.

Of course, limited by the different equipment, the model must have been adjusted, and it will definitely not be perfect in a short time.

In addition, compared with the Xiaoxiao fusion experimental reactor, today's EAST still lacks a first wall material.

Although a suitable manufacturer of zirconia carbon composite materials has been found, due to factors such as production difficulty, the output cannot be increased for the time being.

After the overall replacement of the first wall of the Xiaoxiao experimental reactor, the follow-up needs to provide the first wall material for the demonstration reactor project. On the EAST side, there is no extra output to optimize.

But for short-term manipulation of EAST for deuterium-tritium fusion and lithium-neutron-tritium proliferation and recovery experiments, the lack of these things is not a big problem.

So after the EAST device was changed, Xu Chuan rushed over immediately.

"Have all the preparations been done?"

In the main control room of the EAST device, Xu Chuan looked down at the steel behemoth below through the huge floor-to-ceiling tempered glass window, and asked Yu Mu, the new person in charge.

Compared with the Daybreak Experimental Reactor, the control room on the EAST side is better built.

Not only has a complete monitoring system and protection system, but also the EAST equipment can be seen directly through the tempered glass with the naked eye.

Yu Mu nodded solemnly and replied: "The inspection has been fully completed, please give orders from Academician Xu."

Xu Chuan nodded, and gave an order lightly: "Then let's start."

For him today, a deuterium-tritium fusion ignition experiment is no longer something to be excited about.

But for Yu Mu, who has just taken over the controllable nuclear fusion project in Luyang, this can be said to be the most important thing in his life.

Accompanied by the transmission of instructions.

East, who was sleeping in the core area, woke up.

The liquid helium and liquid nitrogen used for cooling began to be injected into the superconducting magnet pipe of the external field coil respectively, soaking the circles of copper-carbon-silver composite superconductors surrounding the outer track of EAST, and rapidly reducing the superconducting material. temperature.

With the generation of the superconducting effect, a huge current begins to pass through the coil, and with the assistance of the control coil, a powerful confinement magnetic field is formed on the EAST device.

Subsequently, under the action of microwaves from the ICRF antenna, the temperature in the EAST chamber rose rapidly and steadily to the level of 100 million.

The light blue thin film formed by fusion of deuterium-tritium raw material is flowing at high speed in the reactor chamber under the control of the external field coil.

The high-energy neutrons produced by fusion penetrated the material of the first wall and slammed into the liquid lithium molten salt. Lithium nuclei are constantly impacted in the lithium molten salt.

Beads of tritium were manufactured and diffused in the liquid lithium molten salt.

Along with the guidance, these liquid lithium molten salts continue to flow along the cladding, and part of the liquid lithium molten salt material that has participated in the reaction flows out from the guiding port and enters the tritium extraction system.

Here, the tritium in the liquid lithium molten salt will be replaced by hydrogen, then purified, concentrated, and re-transported into the raw material storage tank to participate in the subsequent deuterium-tritium fusion reaction.

At this moment, the fists of everyone in the control couldn't help but clenched.

Even Xu Chuan looked at the already running EAST through the tempered glass, where the hope of realizing controllable nuclear fusion technology is carried.

[Tritium production detected! The tritium extraction system is working fine! 】

A report broke the silence in the main control room.

"pretty!"

"It worked! We did it!"

"Tritium is self-sustaining! I didn't expect that we would be able to participate in solving this kind of problem one day!"

In the control room, the researchers of the EAST project and the Dawn project went crazy.

The last problem has been solved, and they are really no longer far away from controllable nuclear fusion.

Even Xu Chuan, who was standing in the control room, had a bright smile on his face.

The liquid lithium molten salt neutron recovery system he designed has been best verified at this moment.

The rest depends on how efficient neutron recovery can be.

After all, in deuterium-tritium controlled nuclear fusion, more than 80% of the energy is taken away by neutrons. It would be a pity if this part of energy could not be utilized.

The temperature in the chamber of the EAST experimental reactor began to drop rapidly as the ICRF heating antenna ceased operation.

After waiting for the EAST device to cool down, the staff in protective clothing quickly entered the interior of the reaction chamber and took out some accompanying test materials from the first wall.

After all, it is a deuterium-tritium fusion ignition experiment. In addition to verifying the liquid lithium molten salt multiplication tritium system, many other tests can be done.

After the attached test materials were removed, at the same time, the other two groups of workers quickly stepped forward.

A group is responsible for completely dismantling the liquid lithium molten salt breeding tritium system deployed in the envelope for testing.

Another group is responsible for verifying the overall damage condition of the EAST installation.

In the absence of zirconia-carbon composite material as the first wall protection material, deuterium-tritium fusion ignition is carried out. Even with a perfect magnetic field approximation and numerical control model, Xu Chuan estimates that the overall state of EAST will not be much better.

After all, the neutron irradiation produced by deuterium-tritium fusion is really terrible.

In fact, the detection of EAST also confirmed his conjecture.

Not only is the first wall made of tungsten-molybdenum alloy basically completely embrittled, but even the overall structure has been impacted by neutron irradiation and has been damaged to varying degrees.

It can be said that after one experiment, the EAST device is half useless.

But for the process of controllable nuclear fusion, it has made a huge contribution, even if it enters the museum for retirement, it is completely worthwhile.

Xu Chuan returned to Jinling with the data collected almost at the cost of an EAST device.

These data are enough for him to optimize the tritium breeding system in liquid lithium molten salt.

Next time, it will be Lixiao to conduct a more complete experiment on it.

However, it is time to write another letter up.

The test of the liquid lithium molten salt breeding tritium system was successful. Although there are still some areas that need to be optimized, he believes that these are minor problems that will be resolved soon.

The days passed day by day, and in the blink of an eye, it was the beginning of July.

The gate of the demonstration reactor base is quite lively.

All kinds of super-heavy loaded trains stay in the divided site, waiting for unloading.

Under the 24-hour round-the-clock construction with several times the manpower of the nuclear industry group, the industrial park has completed the construction of buildings, and now various equipment is being transported in and deployed to the corresponding places.

Under the leadership of Wang Yongnian and Hou Chengping, two academicians of the Nuclear Industry Group, their resettable magnetic fluid generator set + conventional ultra-supercritical generator set + supercritical generator set are being installed in an orderly manner.

Standing next to the construction site, Academician Wang Yongnian of the Nuclear Industry Group, who was in charge of the site and took command in person, was wearing a hard hat, looking at the magnetism that was hoisted by steel cables and slowly transported towards the power plant under the traction of the cross arm of the crane. A fluid generator, with a hearty smile on his wrinkled old face.

Being able to realize the controllable nuclear fusion technology by himself, even if his role only accounts for a small part in the whole process, still makes him satisfied.

On the side, Hou Chengping squinted his eyes at the equipment being slowly installed, and said with a smile: "I thought I would spend my whole life relying on nuclear fission power generation, but I didn't expect that I would actually preside over the construction of a nuclear fusion demonstration reactor project in my lifetime. "

Looking at the moving generator set not far away, Wang Yongnian grinned rarely after confirming that the assembly was proceeding as scheduled without any problems.

"Yeah, it's like a dream."

After a pause, he continued: "At this time last year, I was still working on the fifth-generation controllable nuclear fission power plant. I didn't expect that in less than a year, controllable nuclear fusion would be realized."

Hou Chengping smiled and sighed: "Compared to this, I am more curious about what kind of existence that person is."

"In the past six months, the more I have been in contact with him, the more I can feel his bottomless depth. It seems that in every field, he can make the greatest achievements."

"Double breakthroughs in the field of theory and application. Throughout history, there may not be a slap in the face that can achieve this step."

"More importantly, he is still so young, he seems to be less than twenty-five years old this year?"

Hearing this, Academician Wang Yongnian thought for a while and said, "If I remember correctly, Academician Xu seems to have lived in 1997, and he is only 24 years old this year."

While communicating, the two watched the installation and deployment of the magnetic fluid generator set.

At this moment, another old man walked towards this side wearing a hard hat.

"Old Wang, Lao Hou, I knew you were here."

The old man who came over cheerfully greeted them, stepped forward and punched each of them, and then he glanced at the magnetic fluid generator set that was still deployed, and said with a smile: "Your progress is a bit slow here, my It's all over."

Hearing this, Wang Yongnian immediately became a little unhappy, glanced at him sideways, and said: "As for your little technical content, I can handle it for you in a week."

The person who spoke to them was Zeng Jitong, another academician of the Chinese Academy of Engineering from the State Grid Corporation of China.

Although the three are not colleagues, they have cooperated many times and are quite familiar with each other.

Not only the nuclear power plant is also used to generate electricity, the people in their nuclear industry group naturally often deal with the people in the State Grid.

This Zeng Jitong is good in everything, and has a good temper. The only shortcoming is that his mouth is a bit awkward and his words are not very flattering.

Just like just now, when he came, he complained that their generator assembly was too slow.

Of course, he didn't hesitate to go back directly.

When Wang Yongnian said that the things he made had no technical content, Zeng Jitong immediately became unhappy.

"Hey, you old man, are you still chattering? Without the converter and grid I made, you can generate p electricity. Also, have you tested the magnetic fluid generator set you designed? If the time comes If you can’t make a call, it’s interesting.”

Wang Yongnian glanced at him indifferently, did not continue to ignore him, and directed the installation of the magnetic fluid generator set on his own.

On the side, Hou Chengping smiled, but didn't care too much.

We are all old acquaintances, but these two seem to be born with conflicts and opposite personalities, and they pinch each other when they meet.

Lao Wang doesn't like to talk very much, and often responds in silence; while Zeng Jitong, although he is very talkative, can't stand being silently attacked by others, and often chases after him.

However, the more he talked, the more lazy Wang Yongnian was to talk to him.

However, this did not delay the cooperative work, on the contrary, it created a pair of happy friends.

As for him, just eat melons and watch the show.
