Chapter 521: It's too wasteful to boil water

These days, Lu Zhou is basically in meetings.
Among them, there are internal meetings of the Jinling Institute of Advanced Research, there are also meetings of the STAR Imaging Research Institute, and there are meetings held by cooperative units ...
He already has a rough blueprint on how to implement a controllable fusion reactor, but he cannot achieve this blueprint alone.
As the person-in-charge and chief designer of this large-scale scientific research project, he must split this huge subject into small parts, and then allocate them to the right people, and separate those difficult parts to focus on, Get rid of.
Just to give an example, topics such as "the recovery of plutonium in plasma ash and the supply of deuterium and tritium fuel" and "safety containment of plutonium" can be found by consulting the Chinese Academy of Sciences.
Therefore, it is natural that he does not need to do this repetitive research work. He only needs to allow people or institutions engaged in research in this field to get sufficient project funding to continue in-depth research, and find ways to use it in the design of stellar simulators. Just go.
As for "the first wall cladding material", "anti-neutron radiation material", "extraction of tritium in multiplication cladding", "and tritium retention", etc., Lu Zhou left it to Jinling. The Higher Research Institute was conquered by himself.
The third day after the project was launched.
In the STAR Institute, Lu Zhou met a working group sent by Huaguo Nuclear Industry Construction Group.
In charge of the team is Academician Wang Zengguang, Chief Engineer of the Nuclear Industry Group. This old academician has worked in the nuclear industry for many years and has extensive experience in the design of fission reactors and nuclear power generating units.
Although the experience accumulated in the fission reactor may not be completely applicable to the fusion reactor, it is also nuclear power, and there are still similarities between the two sides.
For example in the design of generator sets.
Regarding how to convert the thermal energy generated by the reactor into electrical energy, the old academician brought a design sketch.
Drawing on the design ideas of high-temperature gas-cooled reactors, this device can also be used for nuclear fusion power generation.
However, after simply glancing at the sketch, Lu Zhou put it down.
"It is rare to make such advanced technology, and it is too wasteful to continue to boil water."
Academician Wang: "But you can't deny that boiling water is still the most efficient way."
Lu Zhou shook his head: "Not necessarily."
Academician Wang did not speak, but waited for the landing boat to continue.
However, Lu Zhou did not give any explanation. He just took a piece of a4 paper and spread it out on the table. Then he picked up a ballpoint pen and drew a sketch on it.
As the engineering level reached LV4, after a period of adaptation, he finally realized the ability improvement effect brought by the engineering level.
If the mathematics level strengthens the learning of mathematical knowledge, the sensitivity of numbers, and the ability to calculate, then the engineering level not only enhances the absorption of engineering knowledge, but also further strengthens the abstract concept into a language, Graphics, numbers, and more.
Just like now.
Although he has not trained professionally in drawing skills, he has only read relevant books, but the muscles of his arms seem to have memorized these movements, even if he strokes them with one stroke, they are like rulers. Picture-like standard.
Looking at the drawing of the landing boat, Academician Wang narrowed his eyes, and there was an unexpected look in his pupils.
"Have you studied mechanical drawing?"
"No," Lu Zhou said casually. "Maybe when I'm studying geometric problems, I draw more pictures."
Hearing this explanation, Academician Wang had an expression of disbelief.
Although he has not studied mathematical problems, even if he wants to know with his feet, engineering drawing and mathematical drawing are not the same thing at all.
It is impossible to do this skillful stroke without three or five years of professional experience.
Believe it or not, Academician Wang didn't need to explain anything about such insignificant matters, but just focused on the work at hand.
First, the outline of the star simulator was simply outlined with lines, and then the structure of the generator set was simply outlined based on this.
Staring at the more and more clear lines on the map, Academician Wang gradually saw some doorways, and raised his eyebrows with interest.
"Magnetofluidic power generation?"
"Yes," he stopped the comparison, Lu Zhou looked at the sketch, and nodded with satisfaction. "On my level, I can only draw to this extent. The specific design has to be troublesome. You experts. "
Like controllable fusion technology, magnetic fluid power generation technology is not a particularly new concept. It can even be said to have a long history.
Even from the timeline, this concept was first proposed together with the "Gas-Steam Turbine Combined Cycle Technology".
In the 1980s, magnetic fluid power generation technology was even included as a key project of the 863 Program, and in terms of importance, it was placed in parallel with nuclear fission power generation technology.
Considering that the full name of the 863 Plan is "Recommendations on Tracking the Development of Strategic High-Tech in the World", the projects tracked are basically the hot research directions of the international academic community at the time. Fluid power technology can be said to be hot.
However, as we entered the second half of the twentieth century, things changed.
The aerospace and arms races have resulted in rapid development of engine technology and gas application technology. The technology has borrowed and learned a lot of experience from it, and finally realized the counterattack of overtaking in curves.
In contrast, although magnetic fluid technology has a seemingly more attractive prospect, it is difficult to achieve due to technical reasons, and economic benefits can not keep up with market demand. Abandoned by academia and industry mainstream.
Staring at this sketch, Academician Wang shook his head: "IMHO, the technology of magnetic fluid power generation is not perfect, and using it to generate electricity is probably not a suitable choice. Today, nuclear fission reactors in the world are mainly pressurized water reactors. I have never heard of any nuclear power plant that uses magnetic fluid power technology to output electricity. "
It seemed that Academician Wang would say so, Lu Zhou smiled and continued to say
"This is true for nuclear fission, but not for nuclear fusion."
"Oh?" An unexpected expression appeared on Academician Wang's face, and he turned his attention to Lu Zhou. "What?"
Lu Zhou: "The difficulty of magnetic fluid power generation technology is nothing more than the part of gas ionization. It is usually difficult to heat the gas to a high temperature of 2000 degrees and form a plasma beam, and even if it is done, this process is likely to be With a large amount of thermal energy loss, the cycle efficiency of magnetic fluid power generation technology is difficult to achieve more than 20 ... am I right? "
Academician Wang nodded and agreed: "Basically it is."
Although other problems also exist, this is undoubtedly the most important.
Magneto-fluid generators are not without them. Many laboratories can do it. There are coal-fired and oil-fueled ones, but few people can achieve energy conversion efficiency of more than 20 ~ EbookFREE.me ~ but if it is nuclear fusion if……
"If it had been nuclear fusion, we don't have this problem at all," looking at the expression asked by Academician Wang, Lu Zhou continued with a smile, "After all, the nuclear waste generated by DT fusion itself is hundreds of millions of degrees of helium. . "
Upon hearing this, Academician Wang's expression moved slightly, and he immediately looked at the sketch again and quickly reacted.
As we all know, the principle of magnetic fluid power generation is to heat easily ionized gas to a high temperature of 2000 degrees, and ionize it into a conductive plasma beam. When it flows in a magnetic field at high speed, it cuts the magnetic field lines and generates induced electromotive force.
The helium gas generated by the "DT" fusion reaction in the stellarator itself exists in the form of plasma with a temperature of more than 100 million degrees!
In other words, they don't need to spend more energy to heat the ionized gas, they just need to use these plasmas carrying huge energy!
Although this technology is used to burn coal, fuel oil, and even nuclear fission power, it is no doubt that it is tailor-made for nuclear fusion power generation!
Rather, it is wasteful to use those high-temperature plasmas to boil water.
Thinking of this, the academician Wang staring at the sketch gradually became excited in his eyes.
He looked up at Lu Zhou again, and he said in a cautious tone.
"What you said makes a lot of sense ... in theory it seems to be achievable, but now I can't give you an accurate answer, I need to go back and discuss with other experts in the group."
Then he looked at the sketch again.
"Can I take this sketch back?"
"Of course," Lu Zhou nodded gladly, "I look forward to your good news."
