Liquid lithium multiplies tritium, which is nothing new in the comprehensive problem of controlled nuclear fusion.
The tritium self-sustainability problem is one of the key issues. Naturally, many scientists and researchers have explored it for decades.
However, due to the strong magnetic interference of liquid lithium metal from external field coils, major safety hazards will arise. This road is a semi-abandoned path.
For decades, scholars have studied how to solve the problem of tritium proliferation in liquid lithium. After all, liquid lithium proliferation has many advantages over solid lithium proliferation.
But it cannot be solved. Liquid metal will generate electric current when it moves, and the electric current will generate magnetic field. This is the law of electromagnetic induction.
A large part of the reason why life can be born on the earth is that the earth's core is a hot metal core composed of iron and nickel. When it rotates, it generates an extremely huge magnetic field, intercepts the external solar wind, and protects the surface atmosphere and water.
and other substances.
It is very difficult to solve this problem.
The safest way is to find a way to convert liquid lithium into a non-metal, so that it does not generate current and magnetic field under high temperature and flow.
This has always been the direction that the scientific community has been working towards.
However, it has not been very effective, because in order to suppress the induction law of lithium metal batteries, it is necessary to add a large amount of impurities into it, which will directly reduce the lithium content.
The decrease in lithium content will naturally lead to a decrease in tritium, and this is where the trouble lies.
It is necessary to solve the electromagnetic effect of liquid lithium metal without reducing its tritium accumulation efficiency.
The difficulty is like the unparalleled Dharma in the world, which is as good as the Tathagata and not as good as your Majesty.

Hearing Peng Hongxi's question, Xu Chuan smiled.
He stood up, pulled out a blackboard from the office, and said with a smile: "Actually, it's not that difficult."
"The trouble with liquid lithium multiplying tritium is that the liquid metal will generate electric current and magnetic field. If it is suppressed, it will inevitably reduce the lithium content..."
As he spoke, he listed rows of mathematical formulas on the blackboard.
【ΔPMHD\u003dkpσuB2......】
"According to the MHD pressure drop calculation formula, the conductivity (σ) of the liquid metal is proportional to the MHD pressure drop (APMHD). Reducing the conductivity of the liquid multiplier is obviously the most effective method."
"But this method will reduce the production efficiency of tritium. So how to increase the proliferation rate of tritium while reducing the conductivity is the most critical thing."
"I have studied materials and understand some mathematics. Through the technology of breeding tritium in liquid lithium, I have redesigned a set of intelligent calculation methods to improve the tritium breeding ratio of the tritium cladding produced by the fusion reactor."
"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 cladding functional zone of the fusion reactor."
“First, we can calculate the tritium proliferation ratio of the entire cladding module when the kth functional zone is perturbed under first-order perturbation;
Growth ratio..."
"δtbr=tbr(δl′1,δl′2δl′m)-tbr(δl1,δl2...δlm)..."
"...The multi-dimensional second-order analytical function of the tritium reproduction ratio of the entire cladding module as a function of the boundary perturbation of each functional zone is derived."
.......
In the office, Xu Chuan listed rows of calculations on the blackboard and simultaneously explained the key points to Peng Hongxi.
How to solve the problem of liquid lithium multiplying tritium has always been something he has been thinking about, but there has been no progress.
After two academicians from the nuclear industry group in the field of nuclear fission came over, they finally brought him some inspiration.
Its core is taken from a molten salt reactor nuclear fission power station.
In molten salt reactor power stations, fuel salt is the key to the molten salt reactor. It can be used as a carrier of nuclear fuel and as a coolant for nuclear fission reactions. Therefore, it must be dissolved in the molten salt reactor when used.
Fluoride salt is formed in the fluoride salt coolant.
Based on this idea, Xu Chuan used the calculation model in the Chuanhai Institute of Materials to molten salt the lithium metal.
Use materials such as silicon carbide, aluminum oxide, beryllium oxide, or silicon dioxide to make dispersion particles, which are blended into the liquid lithium lead material. While twisting and reducing the liquid lithium lead material, mathematical methods are used to increase the fusion reactor yield.
Tritium reproduction ratio of tritium cladding.
Across the way, Peng Hongxi looked at the calculations on the blackboard and sighed: "Only you can do this."
The method Xu Chuan showed him was not a very advanced or alternative method. It was just an in-depth study of the original method of multiplying tritium with liquid lithium.
But for decades, no one has been able to provide a perfect path. He did it, which is considered unique.
Xu Chuan smiled and said: "Actually, it's not bad. The predecessors have paved the way and have almost explored the method of multiplying tritium in liquid lithium. All I can do is stand on the shoulders of giants and look forward.
"
Peng Hongxi shook his head and stopped chatting on this topic. He said: "I will arrange to verify this method as soon as possible. If the problem of tritium self-sustainment can be solved, the hope of controllable nuclear fusion will really come."
Xu Chuan said with a smile: "Sorry for the trouble, Mr. Peng. Regarding the verification of this method, the Daybreak Fusion Device may not be able to spare the time, but EAST should be able to do it."
Peng Hongxi nodded and said, "I'll make arrangements right away."
........
On the other side, while Xu Chuan and Peng Hongxi were discussing how to solve the final tritium self-sustainment problem, in a residential area near Qixia Mountain, an Asian man who looked Chinese but had a vague sense of being different was wandering by the river.
However, he seemed to have a purpose and was specifically targeting the elderly people walking on Riverview Avenue.
"Hello, old man, I am a reporter and would like to conduct an interview with you. It will be published in newspapers and TV later. What do you think?"
The Asian man caught up with an old man who was walking along Riverview Avenue to eat. He asked with what he thought was a friendly smile, and at the same time showed his "press card."
For him, interviewing in China is something that has proven successful time and time again.
As long as it 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 walking stopped, looked him up and down with his old eyes, and asked, seemingly deaf, "What are you picking?"
Asian man: “An interview that can be on TV!”
Old man: “What can be on TV?”
The Asian man shouted: "An interview that will make you appear on TV!"
"What kind of interview can I get?" the old man asked calmly.
The Asian man sighed. It turned out that he had met a deaf old ghost. He said helplessly: "Old man, please be busy. I'll leave first."
Just as he was about to leave, the old man grabbed him with such force that he couldn't break free for a while.
"It turns out it's an interview. Can it be on TV?" the old man asked curiously.
The Asian man paused and nodded quickly: "Of course. Old man, do you know what is happening on Qixia Mountain nearby?"
The old man squeaked and complained: "Who knows what they are doing? There is a thumping noise every night. It makes my sleep uneasy."
Hearing this, the Asian man quickly asked: "Old man, do you know what the noise is? What is it like?"
The old man frowned and said, "Who cares how the sound is made? It's just a thump, a thump, a thump anyway."
The Asian man didn't continue to ask questions, just thinking that the old man was old and confused, after all, he had just been tortured for a long time.
"Well, old man, you live at the foot of this mountain. Have you seen any planes, tanks, etc. here?"
Hearing this question, the old man frowned, as if thinking.
However, at this moment, two men in casual clothes quickly walked out from the side of Riverview Avenue and walked straight towards the Asian man who claimed to be a reporter.
Noticing the movement around him out of the corner of his eye, the Asian man assessed the situation and felt that there was no hope of escaping, so he pretended to be calm and continued chatting with the old man.
However, the worst happened. Two strong men in plain clothes walked up to him and locked his arms.
"It hurts, let me go, what are you going to do! I'm a reporter, I have a press card!" the Asian man shouted in panic.
The two strong men ignored him, quickly found the recording device and invisible camera device from his jacket pocket, and took them away.
Watching the three people leaving, the old man walking on Jiangjing Road spat and said to himself: "You little bastard, you don't look like a good person at first glance, and you want to trick me into getting information from me?"
Since China launched the Qixia controllable nuclear fusion demonstration reactor project, there have been a lot more foreigners in the city of Jinling, especially near Qixia Mountain, where foreigners are often seen wandering around.
A small number of them had originally planned to come here for fun, and most of them were foreign media reporters, as well as some occasional or overseas intelligence personnel.
These days, he has been interviewing and asking for information from his old man several times, and he has also dealt with plainclothes soldiers, so today he immediately realized 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 agents have been groping nearby, they have not found any information.
The Qixia Mountain area is like a black hole, swallowing up all the information.
But this has increasingly aroused the curiosity of other countries, and they have deployed or even bribed more people to learn about the progress and information here.
Even if every investment disappears without a trace, I still grit my teeth and continue.
After all, this involves technology that can change the entire world.
