Chapter 95 Multilayer Compounding

"Multi-layer composite? Ceramic layer is used as buffering, carbon nanomaterials are used for rapid heat dissipation..."

The nuclear fusion experts and materials experts present were all in deep thought. This plan seemed feasible.

"It's still a cliché issue. The higher the temperature, the more active the substance. The first inner wall needs to face the plasma directly, and the working temperature is between 2,000 and 3,000, which is completely different from the blocking and weakening of less than 1,000 degrees Celsius in Map Laboratory.

Whether higher temperatures will cause carbon nanomaterials to be more active in their properties and react with hydrogen will need to be determined through actual tests."

A material expert raised the question: adding ceramic materials to form a composite structure for temperature buffering. The application of carbon nanomaterials to the first inner wall has met the conditions. It can even be said that carbon nanomaterials are the most suitable compared to other materials in the world.

It is resistant to high temperatures, has relatively good neutron penetration, is thermally inconsistent, and is not bad in neutron radiation. In addition, the material itself is self-repairing, so the little neutron radiation it can withstand can be accomplished by its own repairability.

However, the phenomenon of carbon-hydrogen incompatible reactions to produce methane must be determined through actual tests. If the working temperature increases, this phenomenon will undoubtedly not be qualified as the first inner wall of the carbon nanomaterial.

"You can know this after you go back and test it. Even if this phenomenon still exists, wouldn't it be enough to use nanoceramic material as the first inner wall material and prevent the discrete hydrogen elements in the plasma from contacting the carbon nanomaterial layer?"

Zhang Qingyang Yangyang said confidently: "I wonder if you have any impression of the comb-like structure of the heat dissipation component of the computer cooling system. The poor heat dissipation caused by insufficient thermal conductivity can actually be solved by increasing the heat dissipation area.

Our industrial level cannot reach the level of weaving ceramic materials as silk as Germany, but it is still okay to process ceramic materials into properties like tight combs.

The ceramic material is processed into a comb-like structure, and the carbon nanomaterial is then reversely processed into a reverse shape. The two are merged to form a close fit between the materials, so that carbon nanomaterials with good thermal conductivity can continuously take away the energy from the ceramic material.

Professor Lin and I have just built a mathematical model to analyze the thermal conductivity of carbon nanomaterials, the thermal conductivity of ceramic materials, and the high temperature resistance of ceramic materials.

Through data modeling, as long as the thickness of the nanoceramic material layer facing the plasma is within 0.87 cm, the serrated structure of the rear comb can expand the heat dissipation surface area by more than 6.8 times. Then, relying on the closely-fitting carbon nanomaterials to help heat dissipate, the working temperature of the ceramic material layer can be stably maintained between 2200 and 2400 degrees Celsius.

I think this temperature is still a long way from the melting point of nanoceramic materials. If the thickness of the nanoceramic layer facing the plasma is reduced and the heat dissipation surface area is continued to be increased, then the temperature can be further pressed down.

According to the current material process and the properties of nanoceramics, the plasma discrete hydrogen element is not allowed to penetrate the ceramic layer and react with the carbon nanomaterial behind it. This thickness should not be 0.2 cm.

The requirement of 6.8 times the heat dissipation surface area is even simpler. Design a few more rows of combs in the structure, not to mention 6.8 times, 68 times can be achieved."

After Zhang Qing finished speaking, the materials experts and nuclear fusion experts present couldn't help swallowing their saliva. The look was as if the dawn of nuclear fusion was already in front of her.

Looking at Zhang Qing who was confident, Lu Yi couldn't help but smile. It felt like a home-raised scientist had finally grown up.

"Professor Zhang Qing, the discrete deuterium, tritium, and the helium nucleus generated in plasma will cause irradiation corrosion and low-energy bombardment to the first inner wall material. I just calculated based on the constraint data of tomorrow's imitator, combined with the latest nanoceramic materials' anti-corrosion performance."

The first expert sitting opposite Zhang Qing and Lu Yi stopped the pen in his hand and said with a serious expression: "If ceramic materials are really used as the first inner wall, once the reactor reaches the commercial energy density, the surface layer of the ceramic materials will be corroded and bubbled in about one to two years, and the debris will fall off and enter the plasma to cause safety accidents."

"Ahem!!"

Lu Yi, who originally thought that there were some major flaws in the structural plan conceived by Zhang Qing, was accidentally choked when he heard this. The others in the conference hall also reacted and smiled on his face.

I was discussing how to solve the difficulties encountered in the test reactor just now, but now I have considered commercial application all at once, so I think too early.

"Professor Huang, I think it is commercially valuable for a nuclear fusion reactor that can operate for more than 24 hours a day."

Lu Yi calmed down and coughed, saying: "Of course, as a nuclear reactor, it is really unreasonable to shut down the reactor for core maintenance after only operating for more than a year.

To address this problem, the only solution is to increase the strength of the constrained magnetic field. If the magnetic field strength is increased, the deuterium nucleus, tritium nucleus, and the helium nucleus generated by the reaction discretely crosses the edge of the magnetic field, and the intensity and quantity irradiated on the first inner wall will decrease exponentially."

"Professor Lu, if you are looking for industrial preparation methods to apply superconducting graphene wires to stellar imitators, how long can this time be achieved?"

At this time, except for Lu Yi saying something when he came in, the old man who had not spoken out suddenly asked.

Since we are planning to concentrate our efforts to overcome the commercialization process of nuclear fusion, it is rare to take out valuable time to listen to the meeting. The old man who still has a certain understanding of the recent trends in Lu Yi's laboratory.

As Lu Yi said, in the old man's mind, it is indeed a bit inappropriate for a nuclear reactor to maintain the core components after more than a year of operation.

After all, this kind of project has at least ten days and half a month of core maintenance. In the future, the nuclear fusion reactor will definitely shoulder a huge power generation task. This will take half a month to be suspended for more than a year, which will be a great pressure on power grid regulation.

"Based on the properties of superconducting graphene, if the copper oxide superconducting coil on Tomorrow's imitator is replaced with superconducting graphene wire, the time for the first inner wall ceramic material to persist will be conservatively estimated to be increased to more than 4 years."

Lu Yi turned his head and communicated with Lin Meng. After getting accurate data from mathematicians, he replied seriously.

"good."

The old man nodded, stood up and said, "I have a meeting. The next meeting will be chaired by Minister Hu. Any difficulties in the nuclear fusion project and any support that require the country can be proposed, and do our best to realize the commercial application of nuclear fusion before other countries."

"yes."

Lu Yi and others, Academician Wang and others stood up to respond. I wonder if it was Lu Yi's illusion, but he felt that the old man's current pace seemed to be lighter than what he saw on the news.

Is this happy?
