Chapter 410
The cooling system, the cooling module...these will be the key areas for improvement. Once all the personnel are in place, Wu Tong will deploy them and have dedicated personnel responsible for the research and development. She will optimize and deduce according to the situation, which can save a lot of effort and also help gather everyone's strength to tackle the tough task of controlled nuclear fusion.
Including the later "Tritium recovery in plasma exhaust gas and deuterium-tritium fuel supply" and "Tritium safety containment", these have a certain R&D foundation in China. The people recruited and dispatched this time include the experts in these topics, all of whom are invited to be dispatched.
Once the leaders make up their minds and put all their efforts into doing something, all obstacles will be wiped out. When the forces directly mobilized from above are truly put into doing it, it will be like an unstoppable army pouring down.
As the saying goes, "A person is known only by his own actions." Having completed many projects and learned from experienced seniors for a long time, Wu Tong is already very experienced in planning and arranging projects. He can be considered a good project leader.
Thanks to the great trust, Wu Tong was given the identity of the person in charge and chief designer of this large scientific research project. She was not too nervous, but she was definitely willing to participate in the research and development and be self-disciplined.
When she reported to her superiors, she already had a comprehensive planning blueprint for how to overcome the difficulties in controlled nuclear fusion technology and design a controlled fusion reaction demonstration reactor. Now, everyone is working hard to realize this grand blueprint.
Wu Tong never thought that she was the only capable person in the world. She left professional matters to professionals. She controlled the core, strived for excellence, broke through the biggest difficulties that ordinary people found difficult, and focused on the big and let go of the small. Wu Tong was a good student and naturally learned these management and project operation experiences very well.
She alone cannot realize the blueprint of the fusion reaction demonstration reactor. It is common sense to follow the wise experience of the predecessors and unite all the forces that can be short-circuited. Wu Tong has always known that many hands make light work. She never intends to take on all the technical difficulties by herself. She is a human, not a god. There are so many technical areas. By the time she learns them one by one and makes breakthroughs one by one, it will be too late.
There is a reasonable way to accelerate, why not use it? Professional foreign aid is used reasonably, not shabby or embarrassing.
Therefore, Wu Tong's plan is to divide this huge topic into small professional topics, and then assign them to the appropriate people. She will take charge of the difficult parts and concentrate on solving them. For example, there is no better progress in the first wall material in the world.
After trying from many angles and pausing for a few days, Wu Tong had a new idea. If he couldn't block the neutron beam inside, why not let it go? Then, through certain means, he could recycle the neutrons produced in the DT fusion reaction. Although, this would inevitably constitute a key part of the entire nuclear fusion reactor technology.
But after all, the price of tritium resources is tens of thousands of times that of deuterium. Not only is it sold by gram, but the cost of one gram is as high as tens of thousands of dollars. Their resources are limited and cannot be wasted. Diligence and thrift are traditional Chinese virtues!
This idea was like opening up the Ren and Du meridians. Wu Tong suddenly seemed to be looking down from a higher angle. His thinking was clear and sharp, and new deductions and designs were presented one by one in his writing.
Neutron helium ash recovery system, traversable repairable first wall material... Each unique conceptual technical name was detailed and listed in Wu Tong's notebook, and then turned into continuous deductions on draft paper.
It is impossible to let the neutrons go, and they must be kept. If the neutrons generated by the reaction cannot be recovered, not only will a large amount of energy be lost, but the reactor will also be shut down due to the loss of tritium.
In an ideal fusion reactor, both tritium and neutrons should be preserved as intermediate products, and the only waste produced in the end would be helium and heat.
Letting them go does not mean letting them go.
Wu Tong tried to design the structure of the first wall from many perspectives, both theoretically and technically, to make it possible to avoid the impact of neutron beams. However, from many angles, it was impossible to avoid the damage to the metal bonds. The most fundamental reason for this was that the metal bonds had poor self-repair capabilities, and there was also the difficult-to-solve transmutation problem.
Finally, Wu Tong's focus shifted to metal materials and determined the final research and development direction, with carbon material graphene as the main focus. The stability of carbon materials and the porous special structure of graphene materials were Wu Tong's preferred starting points.
Wu Tong thought about it and planned to develop and design a new material. It was based on the first wall being set to allow neutrons to pass through and having strong self-repair ability. Then, liquid lithium was used to recover neutrons behind the first wall. As for the other side of the liquid lithium, a layer of directional metal was used to reflect neutrons that penetrated the liquid lithium layer without reacting.
This design is equivalent to sandwiching liquid lithium between the first wall and the oriented metal, forming a special sandwich design, which is ring-by-ring combined with a cooling system and other technical support to ultimately achieve an ideal solution.
In order to achieve this project plan, the requirements for the first wall material have changed from extremely high temperature resistance to neutron impact radiation to a new angle. It still needs to be resistant to high temperatures, but the angle of neutron impact radiation has changed from complete resistance to transmission.
The pure carbon material graphene is not enough to withstand such severe high temperatures, so what about the combination? What material elements can be combined to maintain the porous and shuttle effect of graphene materials, while also having sufficient ductility and repairability?
One question after another was thrown into Wu Tong's mind, colliding with Wu Tong's knowledge reserves and scientific research imagination. Up to now, it can be said that Wu Tong's research has entered an unknown field, which also means that there is no more experience of predecessors to refer to. What to do next and how to solve these problems all depend on Wu Tong's own thinking, definition, and design.
Based on the unreliability of metal materials, non-metallic materials became the focus of Wu Tong's attention. Ceramic-based materials were used at this time and are now in front of Wu Tong.
Ceramic matrix composites are a type of composite materials that uses ceramic as the matrix and is composited with various fibers.
The ceramic matrix can be high-temperature structural ceramics such as silicon nitride and silicon carbide. These advanced ceramics have excellent properties such as high temperature resistance, high strength and rigidity, relatively light weight, and corrosion resistance. However, their fatal weakness is brittleness. When under stress, cracks will occur, and even fractures will cause material failure.
The use of high-strength and high-elasticity fibers in combination with a matrix is an effective way to improve the toughness and reliability of ceramics.
