The Science Fiction World of Xueba

Three days later, the controllable nuclear fusion seminar initiated by Pang Xuelin was officially held in a conference room at the headquarters of the Transwarp Institute for Advanced Study.

A total of more than 50 nuclear physicists and material scientists attended the meeting, and several of them were physicists who switched careers.

Pang Xuelin can understand this!

Materials science, nuclear physics and other disciplines are currently hot fields in countries all over the world, and scientists in this field do not worry about funding at all.

Therefore, it is not easy for the Institute of Advanced Studies of the Star Ring to find so many nuclear physicists and material scientists who are well-known around the world.

"Hi everyone, I'm very glad to meet you here today! You must have heard that the Transwarp Institute for Advanced Study is planning to carry out related research in the field of controllable nuclear fusion. I'm calling you here today to hear your thoughts. ..."

Pang Xuelin sat at the top of the meeting room, smiling at everyone present.

At this time, a Caucasian man in his forties said: "Professor Pang, controllable nuclear fusion is currently a research hotspot around the world, and the ITER project jointly built by many countries is in full swing. This project alone, There are more than 20,000 scientific researchers from all over the world involved, and more than thousands of scientific research institutes and manufacturers are involved. Such a super-large-scale scientific project cannot be carried out with just the few people here, right? "

Pang Xuelin smiled slightly, and was prepared for such doubts. He said, "Professor James, I understand what you mean. Although the current controllable nuclear fusion project is an international research hotspot, I think everyone understands that the controllable high-temperature plasma If the steady-state constraint problem and the fusion reactor manufacturing material problem are not solved for a day, even if ITER is successfully completed, it will have no meaning for controllable nuclear fusion research!"

"In my personal judgment, in the next 20 to 30 years, it will be difficult for controllable nuclear fusion to mature!"

"What our Star Ring Research Institute is going to do is not to compete with ITER! We will not build superconducting tokamak or inertial laser confinement fusion devices in a short time. I invite everyone to come over and hope that everyone will discuss the fusion reactor material system. It is also the weakest link in our current controllable nuclear fusion field to start research!"

Everyone present couldn't help looking at each other. No one thought that Pang Xuelin didn't even plan to build experimental devices such as superconducting tokamak or inertial laser confinement fusion, but he wanted to do fusion research?

James asked curiously: "Professor Pang, what about the controllable steady-state constraints of high-temperature plasma? How to solve this problem?"

Pang Xuelin said with a faint smile: "Our fusion reactor material project is only a supplement to ITER in a short period of time.

The controllable steady-state constraint of high-temperature plasma is the focus of ITER's research. We don't pursue perfection in a short period of time. We only need to strive for excellence in the issue of fusion reactor materials. "

With Pang Xuelin's explanation, everyone present can understand it.

Indeed, with the current talent reserve of the Transwarp Institute for Advanced Study in nuclear fusion, it is more realistic to study materials.

The smile on Pang Xuelin’s face did not change at all. Naturally, he would not tell everyone that the Vlasov-Maxwell equations used to describe the controllable steady-state constraints of high-temperature plasma, the NS equations that restrict the motion of fluids, and the equations that restrict the motion of a large number of molecules He has long been familiar with the Boltzmann equation, how to accurately find the analytical solution of these equations.

In the world of Wandering Earth, scientists have long given quite clear results.

Even the computer programs that control the controllable steady-state constraints of high-temperature plasma can be written at any time by using MOSS and the quantum computer it is built on.

For Pang Xuelin, the biggest problem in producing controllable nuclear fusion lies in the field of materials.

The fusion reactor material system is mainly composed of three major systems: fusion reactor cladding, high-temperature plasma-facing components, and magnet materials.

The fusion reactor cladding is further divided into four parts: the structural material of the fusion reactor cladding, the tritium breeding material, the functional material, and the coolant.

High-temperature plasma components are mainly divided into low atomic number materials (low Z materials) and high atomic number materials (high Z materials).

As for the magnet material, it naturally refers to the superconductor material series.

At present, in the Trisolaran world, the material problem of controllable nuclear fusion has been puzzling scientists all over the world.

In the field of fusion reactor structural materials, especially the structural materials of the first screen wall, candidates include low-activation ferritic martensitic steel, vanadium alloys, and silicon carbide fiber composite materials.

Tritium breeding materials can be divided into liquid breeding agents and solid breeding agents.

Liquid proliferators include liquid metal lithium, fluorine lithium beryllium molten salt, liquid lithium-lead alloy, etc.

Solid proliferators are divided into aluminum-lithium alloys, lithium oxide, lithium metaaluminate, lithium metasilicate, lithium metazirconate, lithium titanate and so on.

Functional materials are mainly used to prevent tritium penetration, as an insulating layer, reduce the MHD effect, and as an anti-corrosion layer, mainly oxide coatings, titanium-based ceramic coatings, silicon carbide coatings, etc.

...

There are many candidates for these materials. Different materials, different functions, and different processing properties also have their own advantages and disadvantages.

It takes countless time, energy, and resources to select ones that are suitable for fusion reactors and can be mass-produced at low cost on a large scale.

Pang Xuelin is not optimistic at all that with the current research ecology of various countries, breakthroughs can be made in these fields in the next few decades.

But he is different. In the world of Wandering Earth, although he can't write down the manufacturing methods and production processes of the many materials used in the nuclear fusion reactor, he is very clear about what kind of material is needed for each component.

This alone can save countless time for the researchers of the Star Ring Institute of Advanced Studies.

Next, Pang Xuelin divided the people present into seven major research groups, corresponding to the structural materials of fusion reactor cladding, tritium breeding materials, functional materials, coolants, low atomic number materials, high atomic number materials and superconducting magnet materials These seven groups.

For each group, Pang Xuelin clearly gave two to three materials as key research projects.

Although the scientists here are a little surprised at Pang Xuelin's request, but the other party is a Wallfacer and an investor in this project, so they can only choose to agree.

It took a whole day for Pang Xuelin to determine the overall research direction of the newly established Fusion Materials Research Institute of the Starlink Institute for Advanced Study, and the meeting was considered to be over.

As a result, as soon as Pang Xuelin came out of the meeting room, Cheng Xin rushed up to meet him and said, "Professor Pang, I just got the news that Dr. Luo Ji asked the PDC to hold a hearing for the Wall Facing Project not long ago!"
