Genius of the Rules-Style System

Chen Zeshu took a group of people to see the design of the canned transmission pump, and also went to the operation room to look at some materials.

The current transfer canned pumps are still in the design stage. There are only two civilian transfer canned pumps in the operating room, and their performance is not in line with those used in propelled nuclear reactors for ships.

All they have to do is improve the design and upgrade it from civilian grade to military grade.

The full name of the transfer canned pump used in the nuclear power unit of the nuclear-powered aircraft carrier is called a high-temperature liquid lead-bismuth alloy transfer canned pump.

This is a name that is so complex that it makes one's scalp tingle just looking at it.

In fact, it is simple to understand the name by dividing it into three parts. The first is 'high temperature liquid', which refers to the state and properties of the internal coolant.

Lead-bismuth alloy, as the name suggests, is a lead-bismuth alloy material, which is also the material for manufacturing canned pumps. Lead-bismuth alloy is a low-temperature alloy and a fusible alloy. It is composed of lead and bismuth with a low melting point, and other metals are added to it. To adjust the melting point of the alloy.

The final ‘transfer canned pump’ is a sealless pump. The pump and drive motor are sealed in a pressure vessel filled with the pumped medium. Because it involves the cooling of nuclear reactions, it must be completely leak-free.

After Chen Zeshu gave a detailed introduction, he talked about the problems encountered in research and development, "If you want to improve performance, the design must be improved."

"The main problem we encountered was that after increasing the temperature and sealing, the stator and rotor linkage was not harmonious."

"Look at these two rotating shafts. Above them are the stator and rotor. Several related designs have failed. Either the sealing standards are not enough, or there are other problems..."

"In addition, there are many options for the power input method of the rotor, but we need one that is efficient and stable, but there is none..."

Chen Zeshu said a lot in succession.

After everything was said, he looked at Zhao Yi amusedly and asked, "Academician Zhao, what do you think?"

Everyone else also looked at Zhao Yi.

Just now, Zhao Yi said that they thought the transfer pump technology was simple, so they came to take a closer look. Academician Chen Zeshu also gave a detailed explanation.

If Zhao Yi couldn't say anything, it would be a little embarrassing.

Zhao Yi looked at the design drawing carefully, then pointed to the position of the stator and said seriously, "Academician Chen, there are two questions you just mentioned. The first one is that you can move the stator back nine millimeters and design the periphery into a gear. condition, and add a sealing plug.”

"The position of the rotor needs to be moved forward because of the second problem, power delivery."

"In fact, the best power method is magnetic field tradition, which is transmitted to the mover through the magnetic field of the stator."

"You should be able to understand this, right?"

Zhao Yi seemed to say a few words casually, and others were a little confused. Some people felt that he just didn't want to be embarrassed, so they casually made a few suggestions and continued to look at him with funny eyes.

Chen Zeshu thought so at first, but when he followed Zhao Yi's words and looked at the design drawing carefully and thought about it, his expression suddenly became serious. After about half a minute, he immediately shouted to the associate researcher next to him He shouted, "Call the people from Zhu Lin's office. How many of them are there? Come here!"

"hurry up!"

Everyone else immediately realized something was wrong.

Several people in Zhu Lin's office are responsible for the design of the input canned pump.

This is also their ongoing research project.

Zhu Lin hurried over with several researchers. When he saw Zhao Yi, he immediately said enthusiastically, "Academician Zhao, please meet me. I am Zhu..."

"You're Zhu! It's you! Come here quickly, don't talk nonsense!" Chen Zeshu acted vigorously and immediately pulled the dark-faced Zhu Lin over and talked about Zhao Yi's proposal just now.

Zhu Lin suddenly became serious.

soon.

Several people began to verify the design together.

Chen Zeshu apologized and immediately joined in. The input canned pump was not his project, but he was an academician of the Institute of Nuclear Power. He should pay attention to any project. There seemed to be huge progress in front of him, so he must pay great attention to it.

The next people who received the anti-gravity aircraft team were the administrative and logistics staff. They also apologized repeatedly and said a few words to Chen Zeshu, "That's what Academician Chen is like. The first person in the queue is always the researcher." !”

"It doesn't matter, it's good to see it this way!"

"Research must be important!"

The representatives of the anti-gravity aircraft team were very generous. They all knew the reason. To put it simply, Zhao Yi gave a few small suggestions, and the results seemed to be very useful.

This is really amazing!

Although everyone knows that Zhao Yi is a super genius and has even developed anti-gravity, the specialized technical team of the Nuclear Institute has been developing the design for a period of time. The technical difficulties encountered were solved by Zhao Yi in a few words. After experiencing it, it was still surprising. .

"Academician Zhao..."

"It's really omnipotent!"

"I don't know how helpful it will be. You won't be able to overcome the technical problems all at once, right?"

"It's possible!"

Others were speculating one after another.

Zhao Yi acted very indifferently, as if he had just done a trivial thing.

When someone asked, he just looked indifferent, and his expression was interpreted as, "I told you it was very simple."

Everyone else is a little depressed.

Looking at Zhao Yi's way of solving the problem, it seems that it is really simple, but if you think about it carefully, it is wrong. How can a technical team of the nuclear institute simply solve the design problems encountered during the research and development process?

Although Zhao Yi only said a few words, they must be very crucial, otherwise Academician Chen Zeshu would not be able to behave like that.

So...simple?

For Zhao Yi, it is indeed very simple; for "ordinary people" like them, it is as difficult as climbing to the sky.

The front is correct.

In Zhao Yi's view, it is indeed very simple. First, the input canned pump already has a basic design and has overcome some technical difficulties.

Second, there are more advanced and complete technologies in the world.

After using "Inspection Rate" and "Derivation Rate", he found the shortcomings in the design without even spending a little effort.

In fact, another important reason is that the design of the delivery pressure pump is indeed very simple. In terms of complexity, it is not as complicated as the industrial spindle. The difficulties encountered are only in the design.

As long as it is not a matter of basic theory or a very complex design, for him, it can be classified as "simple".

…

afternoon.

The anti-gravity aircraft team met Chen Zeshu again.

The old academician looked a little tired, but his eyes were full of spiritual meaning. When he saw Zhao Yi, he immediately came over, shook both hands, and said enthusiastically, "Academician Zhao! He is really well-deserved! Everyone else is They say you are a genius, but now you know where the genius is, it is simply amazing!"

"Your suggestions are all to the point. We argued for two hours and found that in theory, the design has completely met the standards!"

"The next step is to enter the manufacturing and testing stages."

"The supporting technology for this nuclear reactor is equivalent to more than half of the problems have been solved, and the rest is just a matter of time."

"When the work is reported, don't worry, Academician Zhao, I will definitely give you a note!"

Zhao Yi said nonchalantly, "It's good to have help, it doesn't matter."

He really didn't care.

Now Zhao Yi has too many achievements. One more or one less small achievement has no impact on him at all.

Next, Chen Zeshu became more enthusiastic. He knew that the purpose of the anti-gravity aircraft team was to see whether nuclear technology could be applied to large instruments and equipment.

Although they don’t know what the specific equipment is, the anti-gravity aircraft team is concerned about nuclear-powered aircraft carrier technology. It must be a similar military propulsion nuclear reactor, just...

The Institute of Nuclear Research does not have relevant mature technologies.

It's not embarrassing.

The whole world knows that there is no relevant mature technology in China. Chen Zeshu also talked about the development of nuclear power plants for aircraft carriers.

What we talked about in the morning was supporting technologies, and in the afternoon we talked about core technologies.

Theoretically, there is no difficulty in using nuclear reactors for aircraft carriers. China has already mastered nuclear reactor technology, and it has mastered not just one but hundreds of nuclear reactor technologies.

Those types that are actually used in practice include large-scale nuclear power plants and military nuclear submarines. In addition, there is also some exploration and coverage in civilian nuclear reactor technology.

"Currently, there are two main points in the research and development of nuclear power plants for aircraft carriers. One is power and the other is abundance."

"The technologies we currently have are either insufficiently powerful or have gaps in abundance, which is the more serious problem."

Chen Zeshu introduced.

There are many types of nuclear reactors, but the ultimate goal is to output power. When actually using them, you need to pay attention to one thing -

life!

If a nuclear reactor requires frequent maintenance, it will definitely not be used for military purposes. What determines its ‘service life’ is abundance, which refers to the abundance of ‘nuclear fuel’.

The abundance of "nuclear fuel" means the concentration of nuclear material in the nuclear fuel. The higher the "abundance" of the nuclear fuel, the greater the heat it releases when a nuclear reaction occurs, and the longer its service life.

According to international standards, if the abundance of nuclear fuel is less than 20%, it is a civilian-level nuclear reactor.

In order to ensure absolute safety, the nuclear fuel in all nuclear power plant reactors is low-concentration uranium-235, with an abundance of about 2 to 5 percent, to ensure that a nuclear explosion is absolutely impossible under any circumstances.

Therefore, every time a nuclear power plant leak is discovered, it is only a leak of radioactive material, rather than an explosion like an atomic bomb.

If the abundance is greater than 20%, it is military grade, and if it is greater than 85%, it can be used to make nuclear bombs.

"Our current nuclear reactor technology is either not rich enough or not powerful enough."

"So, our research on nuclear reactors for aircraft carriers is focused on two directions. One is to increase the power of small reactors for submarines, and the other is to increase the abundance of high-power reactors."

"The former is difficult."

"The latter is equally difficult."

Chen Zeshu used two words "difficult" to conclude, which also shows how difficult the technology is.

The power of small reactors for submarines is not the same as that of reactors for aircraft carriers. Decades ago, many countries hoped to install small reactors for submarines on large aircraft carriers, and they have been conducting related research.

If we continue to do similar research now, the possibility of developing it is very slim.

Improving the abundance of fuel for high-power reactors is at least much better than "international research that has produced no results for decades."

Of course, the difficulty is also very high.

For example, the high-power reactors used in nuclear power plants are theoretically enough to be used by large aircraft carriers, but their abundance is less than 10%, which means that the fuel must be replaced every few years.

For large aircraft carriers, every change of fuel is like rebuilding it, and its high maintenance costs and time costs are simply unaffordable.

In comparison, the nuclear fuel abundance of the A-4W reactor of M's Nimitz-class nuclear-powered aircraft carrier is as high as 60%, which means that it can work continuously for more than 20 years. During the service life of an aircraft carrier, it only needs Just change the fuel once or twice, and the efficiency is very high.

The A1B pressurized water nuclear reactor used in the "Ford-class" nuclear-powered aircraft carrier under construction has an unprecedented 97% nuclear fuel abundance. In theory, the aircraft carrier does not need to change fuel during its service life. , installed from the time of construction and never need to be replaced.

Chen Zeshu said a lot.

Zhao Yi also listened to a lot of content, and his summary was different from what Chen Zeshu said. His conclusion is that there are many types of nuclear reactors and many technologies, which leads to many possible research and development directions.

Although Chen Zeshu believes that increasing the abundance of high-power reactors is a good route, his tone is not completely certain. In other words, the direction of increasing the abundance of high-power reactors is only the result of discussions by the research group of the Nuclear Research Institute.

What if it's wrong?

Before technological breakthroughs are made, no one dares to say that the direction chosen is correct.

Others were mildly disappointed.

The purpose of their visit to the Nuclear Research Institute was not to study nuclear reactor technology. After understanding a lot of content, they just came up with the answer that "there is no mature technology available". The result was of course disappointing.

Although I had thought about it before coming, I was still a little disappointed.

Chen Zeshu did not give a definite answer, saying how many years later we will have aircraft carrier nuclear power plant technology, which means he cannot even look forward to the future.

People from the anti-gravity aircraft team began to discuss whether a reactor with low abundance and high power could be used, but the final result was of course 'no'.

There is no doubt that the power required by the flying fortress, and considering future service, is definitely higher than that of a large aircraft carrier.

Nuclear power plant technology cannot even meet the needs of large aircraft carriers, and it is even less likely to meet the power needs of the flying fortress.

Zhao Yi was not disappointed with this. He was not part of the anti-gravity aircraft team. Anti-gravity was developed by him, but he only provided theory and technology. It was not his job to design the aerial fortress.

The purpose of his visit this time is to learn about nuclear-related theoretical techniques in order to supplement his understanding of particle physics, which may help improve the boundary theory and analyze the divine code.

After the anti-gravity aircraft team members left, Zhao Yi stayed. He decided to stay for a few days to discuss nuclear physics issues with several nuclear experts from the Nuclear Institute.
