Great Country Academician

The multiplication of tritium by liquid lithium is nothing new in the comprehensive problem of controlled nuclear fusion.

The problem of tritium self-sustainability is one of the key problems, and naturally many scientists and researchers have explored it for decades.

However, limited by the strong magnetic interference of liquid lithium metal in the external field coil, there will be major safety hazards. This road is a half-abandoned trail.

For decades, it is not that no scholars have studied how to solve the problem of liquid lithium proliferation of tritium. After all, compared with solid lithium proliferation, liquid lithium proliferation has many advantages.

But it can't be solved. Liquid metal will generate current when it moves, and the current will generate magnetic field. This is the law of electromagnetic induction.

A large part of the reason why the earth can give birth to life is that the earth's core is a hot metal core composed of iron and nickel. When it rotates, it generates an extremely large magnetic field, intercepts the external solar wind, and protects the atmosphere and water on the surface. and other substances.

It is very difficult to solve this trouble.

The safest way is to find a way to transform liquid lithium into a non-metal, so that it does not generate current and magnetic field under high temperature and flow.

This is what the scientific community has been working towards all along.

However, there is not much effect, because to suppress the induction law of lithium metal batteries, it is necessary to dope a large amount of impurities into it, which will directly reduce the lithium content.

And the reduction of lithium content will naturally lead to the reduction of tritium, which is the trouble point.

It is necessary to solve the electromagnetic effect of liquid lithium metal without reducing its tritium accumulation efficiency.

The difficulty is like the unparalleled and perfect method in the world, which is the same as living up to the Tathagata and living up to you.

Hearing Peng Hongxi's question, Xu Chuan smiled.

Standing up, he dragged out a blackboard from the office, and said with a smile, "It's actually not that difficult."

"The trouble with liquid lithium proliferating tritium is that liquid metal will generate electric current and magnetic field, and if it is suppressed, it will inevitably reduce the lithium content."

As he spoke, he listed lines of mathematical formulas on the blackboard.

【ΔPMHD=kρσuB2】

"According to the calculation formula of MHD pressure drop, the conductivity (σ) of liquid metal is directly proportional to the size of MHD pressure drop (APMHD). It is obviously the most effective method to reduce the conductivity of the liquid proliferator."

"But this method will reduce the production efficiency of tritium. So how to increase tritium while reducing the conductivity is the proliferation rate, which is the most critical thing."

"I have studied materials and know some mathematics. Through the technology of breeding tritium with liquid lithium, I redesigned a set of intelligent calculation methods to increase the ratio of tritium breeding in the cladding of tritium produced by fusion reactors."

"The principle is based on high-order neutron perturbation theory and simulated annealing algorithm, which can quickly find the global optimal solution by automatically adjusting the geometric boundary of the tritium-producing cladding functional area of ​​the fusion reactor."

"Firstly, the tritium breeding ratio of the entire cladding module can be calculated by calculating the tritium breeding ratio of the entire cladding module when the kth functional zone is disturbed under the first-order perturbation; Br"

"δtbr = tbr(δl'1, δl'2δl'm) - tbr(δl1, δl2...δlm)"

".Deduce the multidimensional second-order analytical function of the tritium breeding ratio of the entire cladding module as a function of the boundary disturbance of each functional zone."

In the office, Xu Chuan listed the next line of calculations on the blackboard, and explained the core to Peng Hongxi at the same time.

How to solve the problem of proliferating tritium in liquid lithium has always been the point of his thinking, but there has been no progress.

After two academicians in the field of nuclear fission from the nuclear industry group came over, they finally brought him some inspiration.

Its core is taken from a molten salt reactor nuclear fission power plant.

In the molten salt reactor power station, fuel salt is the key to the molten salt reactor. It can be used not only as a carrier of nuclear fuel, but also as a coolant for nuclear fission reactions. Therefore, it must be dissolved in Fluoride salts are formed in fluoride salt coolants.

According to this idea, Xu Chuan used the calculation model in Chuanhai Materials Research Institute to carry out molten salting of lithium metal.

Use silicon carbide, aluminum oxide, beryllium oxide, or silicon dioxide to make dispersed particles, blend them into liquid lithium-lead materials, reverse and reduce liquid lithium-lead materials, and use mathematical methods to increase the tritium cladding tritium produced by fusion reactors reproduction ratio.

On the opposite side, Peng Hongxi looked at the calculation formula on the blackboard and sighed: "This way, you can do it."

The method that Xu Chuan showed him was not a very advanced or another method, but it was just a deepening of the original method of proliferating tritium with liquid lithium.

But for decades, no one has been able to give a perfect path, and he has done it, which is considered unique.

Xu Chuan smiled and said: "It's actually not bad. The predecessors have paved the way and have already explored the method of tritium multiplied by liquid lithium. All I can do is stand on the shoulders of giants and look forward. "

Peng Hongxi shook his head, stopped chatting on this, and said, "I will arrange to verify this method as soon as possible. If the problem of tritium self-sustainability can be solved, the hope of controllable nuclear fusion will really come."

Xu Chuan said with a smile: "I'm sorry, Mr. Peng. Regarding the verification of this method, the Lixiao fusion device may not be able to spare time, but EAST should be able to do it."

Peng Hongxi nodded and said, "I'll arrange it right away."

On the other side, when Xu Chuan and Peng Hongxi were discussing how to solve the final tritium self-sufficiency difficulty, in a residential area near Qixia Mountain, a man who looked like Chinese, but felt somewhat different was wandering by the riverside.

However, he seemed to be purposeful, and only aimed at the elderly people who were walking in Jiangjing Boulevard.

"Hi, old man, I'm a reporter. I want to interview you. I'll post it in newspapers and TV later. What do you think?"

The Asian man caught up with an old man who was taking a walk along Jiangjing Avenue to digest his food. He asked with a smile that he thought he was kind, and at the same time showed his 'press card'.

For him, interviewing in Huaguo is a tried and tested point.

As long as they can be published in newspapers or on TV and make them famous, many people will be happy to accept it.

The old man who was taking a walk stopped, looked him up and down, and asked with a deaf ear, "What are you picking?"

Asian man: "Can be interviewed on TV!"

Old man: "What can be on TV?"

Asian man yelled: "Interview for TV!"

"What kind of interview can I have?" The old man asked calmly.

The Asian man heaved a long sigh. He met an old ghost with deaf ears, and said helplessly, "Old man, please be busy. I'll go first."

Just when he was about to leave, the old man grabbed him with a strong hand, and he couldn't break free for a while.

"It turned out to be an interview, can it be on TV?" the old man asked curiously.

The Asian man paused, nodded quickly and said, "Of course. Old man, do you know what's going on on the Qixia Mountain nearby?"

The old man snorted, and complained: "Who knows what they are doing, every night there is a thump, thump, thump, and sleep is disturbed by the noise."

Hearing this, the Asian man quickly asked: "The old man, do you know what the noises are? What are they like?"

The old man frowned and said, "Who cares what the noise is, anyway, it's just dong dong dong."

The Asian man didn't continue to ask questions, he just thought that the old man was getting confused because he had been tossing him for a long time.

"The old man, you live at the foot of this mountain, have you seen planes, tanks, etc. here?"

Hearing this question, the old man frowned, as if thinking.

However, at this moment, two men in casual clothes quickly came out from the side of Jiangjing Avenue, and walked straight to the Asian man who claimed to be a reporter.

Out of the corner of his eye, he noticed the movement around him. The Asian man assessed the situation and felt that there was no hope of escape, so he continued to chat with the old man pretending to be calm.

However, the worst situation came. Two strong men in plain clothes walked up and directly locked his arms.

"It hurts, let me go, what are you going to do! I am a reporter, and I have a press card!" the Asian man shouted in panic.

The two strong men ignored him, quickly found the recording equipment and the invisible camera equipment from his jacket pocket, and took them away.

Looking at the three people who left, the old man who was walking on Jiangjing Road spat and said to himself: "Little bastard, you don't look like a good person at first glance, and you still want to trick me into getting news from me?"

Since Huaguo launched the Qixia Controllable Nuclear Fusion Demonstration Reactor project, there have been many foreigners in Jinling, especially near Qixia Mountain, where foreigners are often seen wandering around.

A small number of them originally planned to come to play, and most of them were foreign media reporters, as well as some spies or overseas intelligence personnel.

These days, I have approached him several times for interviews and inquired about news, and I have also dealt with those plainclothes soldiers, so today he realized for the first time that this Asian who looked like a compatriot might not be a Chinese, so he pulled him The chat dragged on for a while.

Sure enough, soon, the security personnel here took him away.

For the elderly, those who can be taken away by security soldiers are pests who want to destroy the peace of the motherland.

I have to say that in terms of controllable nuclear fusion, the confidentiality work is still very good.

Although foreign intelligence personnel have been groping around, they have not found any news.

The Qixia Mountain area is like a black hole, swallowing all the information.

But this has also aroused the curiosity of other countries more and more, and even bought more people, wanting to inquire about the progress and information here.

Even if every investment disappeared without a trace, he still gritted his teeth and continued.

After all, this involves technology that can change the entire world pattern.

PS: The state of the past two days is average, and the things I wrote are a bit stretched. Originally, there were two updates today, but after reading it, I felt dissatisfied and deleted a chapter. Let’s see the situation tomorrow, and the ignition is fast. , in these two days.
