Before returning to the college entrance examination, I became popular in the science circle

"Fight for energy, fight for China!"

Why don't men take Wu Gou and collect the fifty states in Guanshan? Which good Chinese son or daughter has no blood in his heart?Wu Tong's last encouragement immediately aroused the youthful passion in the hearts of the team members in the conference room. Almost as soon as Wu Tong finished speaking, everyone spoke in unison, shouting out with one voice.

"Mr. Wu, tell us where to go and what to do, we will charge forward and do whatever you want!" Ruan Chengxu responded immediately, promising that he never expected that in just one or two years after graduation, he had already grown up I feel that being able to be exposed to the development of such a big project is all thanks to the guidance of my junior sister Wu Tong.

Therefore, no matter what decision Wu Tong makes, he will support it immediately.In formal occasions, Ruan Chengxu also calls Wu Tong by his honorific title and never puts himself in a special position because of his relationship with Wu Tong.

"Yes, that's it. Mr. Wu, just tell us what to do, and we will follow you and do our best!" Nie Qiyun started, and the others expressed their opinions one by one.Isn’t it controllable nuclear fusion?In front of their boss, Wu, they believe that there will definitely be no problem. Maybe in the future, they can also study flying saucers, interstellar fortresses... those infinite reveries in science fiction.

Wu Tong's words, "Imagine as much as you want," really freed up the minds of the participants here.Hehe, Mr. Wu is the beacon for their progress and their confidence. With Mr. Wu here, they really think things that ordinary people dare not think of.

They are participating in a great research and development. If they succeed, their country and their people will benefit from it. The value of this is not comparable to any money or other things. Just think about it, they are full of passion. , instantly full of power to move forward.

"Thank you everyone for your trust and support in me. Controllable nuclear fusion is a huge project that cannot be completed overnight. Don't be overly excited. We have to save our energy and energy first, and work hard one by one. To overcome the difficulties. Let’s get back to the subject, let’s start from the fundamentals and move on to the next topic. Discussion on the research and development of high-temperature resistant materials for the first wall!”

Wu Tong is grateful for the trust and support of the team. With such a good start, Wu Tong started the next topic, which is also their recent research and development goal.If it were in the past, Wu Tong would directly start the deduction from scratch until the complete technology is available, and then the team will conduct auxiliary experiments to verify it.

Although this kind of process is a relatively fast mode, she often leads the charge alone. Her thoughts and ideas, no matter how comprehensive they are, are one-sided and limited after all.

From the research and development of lithium-sulfur batteries, Wu Tong conducted heuristic training on the team and explored the team's capabilities. He also felt the rapid growth of the team and the inspirational help from everyone adding fuel to the fire.

Therefore, this time, Wu Tong still wants to continue this excellent model, and is ready to continue to participate collectively with the team and gather everyone's imagination to quickly find out the best direction for them to move forward.

"The nuclear fusion reaction needs to reach at least one million degrees Celsius, and normal and stable operation needs to reach over [-] million degrees Celsius. No solid material currently known on earth can withstand such a high temperature. Any material at this temperature will become Gaseous plasma. Therefore, to achieve nuclear fusion, the research and development of our first wall materials is crucial. We need to develop a material that can withstand hundreds of millions of high temperatures and withstand plasma impact as a container. Such a container must both It can make nuclear fusion continue to operate, it can also turn the energy of nuclear fusion into electrical energy, and it can also continue to withstand the high temperature generated by the nuclear fusion reaction!"

After cooperating in the last new energy research and development project, everyone was familiar with this research model, and they immediately made active speeches about their knowledge of nuclear fusion.

"The sun ignites and restrains nuclear fusion reactions through strong gravity. The principle of the stellarator device is to imitate a mini sun. Of course, we are imitating it, not building it for real.

In order to maintain nuclear fusion, even Jupiter, which has a mass of more than 300 times the mass of the Earth, cannot achieve it. It must reach hundreds of times the mass of Jupiter.Therefore, all of us living on the earth are earthlings, and it is impossible to create an artificial small sun on the earth that is maintained by gravity.

We have to exclude gravity.The current mainstream is to use a strong magnetic field to replace gravity to control and bind the fusion reaction plasma!Our superconducting materials have laid a solid foundation for us to achieve this control. Previously, the most high-temperature resistant material in the world should be the tantalum-hafnium carbide alloy Ta4HfC5, which can withstand temperatures of nearly [-] degrees Celsius! "

"But this is still not enough. The fusion reaction requires the first wall to be able to withstand the starting temperature of [-] million degrees Celsius and continue to operate!" At [-] degrees, it is basically suitable for general aerospace needs, including the ones they developed before. Carbon fiber high temperature resistant materials and other excellent high temperature resistant materials are not enough in this position.

"Yes, the sun has solar wind and thermal radiation. A controllable nuclear fusion device will release thermal radiation and high-temperature particle wind. The biggest difference between nuclear fusion reaction and nuclear fission reaction is that nuclear fusion reaction must be completed under high temperature and pressure. Nuclear fission reactions do not require such high temperatures and can even be carried out at very low temperatures, so the equipment performance of traditional nuclear power plants is still different from that of nuclear fusion reactors.

The first wall is the inner wall of the equipment that needs to directly face the nuclear reactor thermal radiation and high-temperature particle wind. The thermal radiation faced by the first wall is not simple infrared rays, but high-energy rays mainly X-rays. These rays are very It is easy to break chemical bonds, thus destroying the structure of solid materials and causing damage to the first wall.

This is one of the difficulties we have to consider when developing first-wall materials. Secondly, as Mr. Wu said, no matter how strong the magnetism is in neutron impact or artificial nuclear fusion equipment, some plasma will reach the magnetic confinement range. foreign.Once these particle flows hit the first wall, they will cause certain corrosion to the first wall.

And the nuclear fusion reaction will use deuterium-tritium nuclear fusion. The deuterium-tritium reaction will produce neutrons. These neutrons are not controlled by the magnetic field and can hit the first wall at will.When neutrons hit the first wall, they have a certain chance of having a nuclear reaction with the atoms on the first wall. Such a nuclear reaction will turn one kind of atom into another kind of atom. With the nuclear reaction of the atom,

The interior of the first wall will be damaged, and the originally designed structural parameters will gradually no longer meet the design requirements.Bubbles or cracks may even form inside, further damaging the material's structure.It will also cause damage to the first wall! "(End of chapter)
