"Fight for energy, fight for China!"

Why don't men take up Wu Gou and conquer the fifty states of Guanshan? Which son and daughter of China doesn't have passion in their hearts? Wu Tong's final words of encouragement instantly stirred the youthful passion of the team members in the conference room. Almost as soon as Wu Tong finished speaking, everyone spoke up, united in purpose and shouting out in unison.

"Boss Wu, you tell us where to go and what to do, and we will charge forward and do it!" Ruan Chengxu responded immediately and made the promise. He never thought that after only one or two years of graduation, he had grown to the point where he could be involved in the development of such a large project. All this was thanks to the guidance of his junior sister Wu Tong.

Therefore, no matter what decision Wu Tong made, he would immediately support him. In formal occasions, Ruan Chengxu also addressed Wu Tong with a respectful title, never putting himself in a special position because of their relationship as fellow disciples.

"Yes, that's right, Mr. Wu. Just tell us what to do, and we'll all follow your lead and give it our all!" Nie Qiyun began, and the others began to voice their opinions. Isn't it just controlled nuclear fusion? In front of Mr. Wu, they believed there would be absolutely no problems. Who knows, maybe in the future they could even research flying saucers, interstellar fortresses... those endless sci-fi fantasies.

Wu Tong's words, "Let your imagination run wild," truly set the minds of the attendees free. Hey, Mr. Wu is their guiding light, their confidence. With Mr. Wu around, they can truly imagine things that ordinary people wouldn't dare to.

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 anything else. Just thinking about it makes them full of passion and instantly full of energy to move forward.

"Thank you all for your trust and support. Controlled nuclear fusion is a massive undertaking, not something that can be accomplished overnight. Let's not get overly excited yet. Let's gather our energy and resolve, and tackle each challenge one by one. Now, let's get back to the basics and move on to the next topic: the research and development of high-temperature-resistant materials for the first wall!"

Wu Tong is grateful for the team's trust and support. With this positive start, he embarked on the next topic, their immediate research and development goal. In the past, Wu Tong would have started from scratch, developing a complete technology, and then conducting auxiliary experiments to verify it with the team.

Although this process is a relatively fast model, she is often the only one who charges into battle. Her thoughts and ideas, no matter how comprehensive they seem, are ultimately one-sided and limited.

From the research and development of lithium-sulfur batteries, Wu Tong gained a thorough understanding of the team's heuristic training and discovered the team's capabilities. He also felt the team's rapid growth and the inspiration that came 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 lead the team to participate collectively, gather everyone's imagination, and find out the best direction for them to move forward more quickly.

"Nuclear fusion reactions require temperatures exceeding one million degrees Celsius, and normal, stable operation requires temperatures exceeding 100 million degrees Celsius. No solid material on Earth is known to withstand such high temperatures; any substance at these temperatures will transform into a gaseous plasma.

Therefore, the prerequisite for achieving nuclear fusion is that our first-wall material research and development is crucial. We need to develop a material that can withstand temperatures exceeding 100 million kilowatts and withstand plasma impact to serve as a container. Such a container must not only allow nuclear fusion to continue operating, but also be able to convert the energy of nuclear fusion into electricity, and it must also be able to continuously withstand the high temperatures generated by the nuclear fusion reaction!

After cooperating in the last new energy research and development project, everyone was familiar with this discussion mode and immediately spoke actively about the nuclear fusion knowledge they knew.

"The sun ignites and confines nuclear fusion reactions through its powerful gravity. The principle of the stellarator device is to imitate a miniature sun. Of course, we are imitating it, not building it realistically.

To sustain nuclear fusion, even a Jupiter with a mass over 300 times that of Earth wouldn't be able to achieve it; it would have to be hundreds of times more massive. Therefore, living on Earth, we are all Earthlings, and it's impossible to create an artificial sun on Earth that relies on gravity to sustain it.

We have to rule out gravity. The current mainstream method is to use a powerful magnetic field to control and confine the fusion reaction plasma instead of gravity! Our superconducting materials have laid a solid foundation for us to achieve this control. Previously, the most heat-resistant material in the world was probably the tantalum-hafnium carbide alloy Ta4HfC5, which can withstand temperatures of nearly 4,000 degrees Celsius!

"But this is still not enough. The fusion reaction requires the first wall to be able to withstand a high temperature of 100 million degrees Celsius and continue to operate!" Four thousand degrees is basically enough for general aerospace needs, including the carbon fiber high-temperature resistant materials and other excellent high-temperature resistant materials they developed previously. At this level, they are not enough.

"Yes, the sun produces solar wind and thermal radiation. A controlled nuclear fusion device will release thermal radiation and high-temperature particle winds. The biggest difference between nuclear fusion reactions and nuclear fission reactions is that nuclear fusion reactions must be completed under high temperature and pressure, while nuclear fission reactions do not require such high temperatures and can even proceed at very low temperatures. Therefore, the performance of traditional nuclear power plant equipment is different from that of nuclear fusion reactors.

The first wall is the inner wall of the equipment that needs to directly face the thermal radiation of the nuclear reactor and the high-temperature particle wind. The thermal radiation faced by the first wall is not simple infrared rays, but high-energy rays mainly composed of X-rays. These rays can easily destroy chemical bonds, thereby 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 the first wall material. Secondly, as Mr. Wu mentioned, in neutron impact, in artificial nuclear fusion equipment, no matter how strong the magnetism is, some plasma will escape the magnetic confinement range. Once these particle flows hit the first wall, they will cause some corrosion to the first wall.

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 the neutrons hit the first wall, there is a certain chance that they will react with the atoms in the first wall. Such a nuclear reaction will turn one type of atom into another type of atom. As the atoms react,

The interior of the first wall will be damaged, and the originally designed structural parameters will gradually no longer meet the design requirements. It may even form bubbles or cracks inside, further destroying the material structure. This will also cause damage to the first wall!
