Du Kuiyang left.
He came with pride, but he left Hua Xia with a heart full of unwillingness and deep fear.
On the plane, Du Kuiyang couldn't calm down for a long time.
"If it weren't for the mobile phone business of the Monster Industry and the Thunderbolt Automobile business being so profitable, I think the most cutting-edge industrial processing technology in our entire country would be beaten by the Monster Industry without any power to fight back." Du Jingyang covered his lips, and his words trembled a little.
The scene that happened in the guest house's reception room not long ago made Du Kuiyang thoroughly realize the unparalleled power of Monster Industries.
Fortunately, Monster Industries was only a company, not a country, and could take care of all industries in all aspects. If they immersed themselves in the industrial processing robot and machine tool market and didn't come out, Du Kuiyang felt that it would be better for him to resign early and come to Monster Industries to make a living.
"Teacher, I don't understand. That expert said that they stacked seven special single-crystal alloys together. How did they do it? Different metals have different properties and melting points. In theory, they can't be stacked together. "
Du Kuiyang glanced at this disciple who asked questions because he didn't understand. His eyes were full of bitterness.
You ask me, but who should I ask?
Du Kuiyang thought in his heart, but his mouth said vaguely, "Maybe they have mastered a very special sintering technology. Moreover, the exploration robot used in the interior of the nuclear reactor doesn't need a high level of physical protection. The strength of the shell isn't important, as long as it can solve the problem of nuclear radiation."
"It's terrifying. They claimed that the protective strength of the shell is equivalent to 110 atomic number. I'm afraid that only the United States ten years later can achieve such data. "
"I remember … Monster Industries was established less than two years ago, right?" Du Kuiyang sighed. "Unfortunately, it's all too late. If only we knew earlier that Monster Industries had mastered this technology …"
"Teacher …"
Another disciple hesitantly interrupted. "Actually, last year, we had a deal with Monster Industries. At that time, they were still called Monster Heavy Industries. "
"We?" Du Kuiyang immediately turned his head. "What do you mean by 'we'?"
"It's our Japan University of Technology." Another disciple who serves as a mechanical engineering professor in Japan Institute of Technology sighed heavily. "Last year, we held an academic exchange with Hua Xia Zhongyun University."
"We originally wanted to show off our power to Hua Xia by using an ultra-high precision bolt to stump Zhongyun University. The final result was similar to today."
"Zhongyun University has urgently invited the young CEO of Monster Industries to be their foreign aid. He used to be a student of Zhongyun University and was said to be a graduate student. Then, this young CEO only took two days to catch a handful of nuts. You have to know that even we don't have much confidence in making a nut, but he actually grabbed a bunch. "
Later, they gave our Japan University of Technology an iron ruler and asked us to carve words on it. "
Duhei Yangtai said in astonishment, "Last year, I was doing technical research in Fukushima. Why didn't I hear you mention this?"
"Have the words been carved?"
The disciple hesitated for a long time before he finally choked out a sentence.
"Last year's incident was too shameful, I... we, how can we still publicize it everywhere?" After that, he took out his mobile phone from his pocket and turned out a picture. Duhei Yangtai looked at the picture intently. In the picture, there was a dark back of an iron ruler, which attracted all his attention.
Duhei Yangtai knew that the front of the iron ruler was engraved with the words [Friendship for a Long Time], and the young CEO asked them to engrave [Teacher of the Century]. Of course, these four words could not be engraved. It was equivalent to admitting that Hua Xia was their teacher. But Japan University of Technology also had to engrave words to prove that they could do it, any four words, otherwise their skills were not as good as others.
As a result, Duhei Yangtai saw a few crooked scratches on the iron ruler. These scratches had traces of laser burning, electric sparks, and plasma cutting, and two kinds of traces that he could not see for the time being.
But these scratches were not words at all, nor were they made by the same equipment.
It seemed that Japan University of Technology had tried almost all methods, but they did not succeed in finding a way to engrave words.
Duhei Yangtai gasped again.
…
At the same time, Ye Qing also got the urgently needed nuclear core and cooling water information.
Academician Liu himself was a top expert in nuclear reactors in China, so he was familiar with the knowledge of nuclear energy theory.
He told Ye Qing that the technical principle of the aircraft carrier reactor was the same as that of the commercial power plant reactor, but in actual use, the nuclear core parameters would be very different. The biggest difference was the concentration of Uranium-235 in the nuclear core.
For ordinary commercial nuclear power plants, the purity of Uranium-235 was only 3% to 6%, and the fuel needed to be changed once a year.
However, the nuclear core used by the US aircraft carrier was weapons-grade uranium disassembled directly from retired nuclear warheads. The Uranium-235 concentration was more than 95%, and it could work continuously for 30 years with more power.
Academician Liu told Ye Qing that if Hua Xia built a nuclear-powered aircraft carrier, the Uranium-235 concentration in the nuclear core would be at most 60% to 80%. This was because the higher the concentration of Uranium-235, the higher the cost of funds needed to purify it.
The US produced a large number of nuclear warheads during the Cold War. After these nuclear warheads were retired, the Navy simply took back the nuclear fuel cores used for warships. Hua Xia did not have this historical accumulation, so naturally, they could not imitate the rich US. Academician Liu also told Ye Qing that after the Cold War, the US stored about thousands of tons of weapons-grade uranium, which was enough for the warships to use for more than a thousand years.
Using weapons-grade uranium as a nuclear core was very luxurious and very advanced technology.
Fortunately, the nuclear core theory of weapons-grade uranium was not complicated. It was only difficult to manufacture it.
The last question was, at noon, when Ye Qing and Academician Liu were eating in the guest house, they chatted and asked why the US aircraft carrier reactor was equipped with ordinary steam turbine units, and not supercritical or even ultra-supercritical.
The latter laughed and said that it was related to the nuclear core manufacturing technology.
Even the US, the most powerful country in the world, was not confident in producing qualified nuclear core materials.
Academician Liu gave an example. A fuel core in the reactor core of a warship was only one centimeter long and one centimeter wide, but it could release energy equivalent to hundreds of tons of coal. Countless fuel cores were loaded in the fuel rod. During fission, the internal temperature of the fuel rod was usually maintained at 700 to 800 degrees. However, the fuel rod was directly in contact with the cooling water of the primary circuit, which heated the cooling water to 300 degrees. The fuel rod made of a special alloy would work in an underwater environment with different internal and external temperatures for a long time.
The internal and external temperatures were different, and it had to be subjected to high temperatures for a long time. The material properties of the metal would be greatly tested. The slightest carelessness could cause the fuel rod to break. When the Fukushima power station caught fire, it was because of the failure of the primary circuit cooling system, which caused the cooling water level to drop and could not cover the entire fuel rod. The upper half of the fuel rod was exposed to the air, and then the tragedy of the fuel rod breaking occurred.
The breaking of the fuel rod was directly a level 7 nuclear accident, and the consequences were similar to Fukushima.
If one wanted to use supercritical, the internal temperature of the fuel rod would be as high as 1,000 degrees, and the primary circuit cooling water would also undergo a qualitative change.
Ultra-supercritical required 1,200 degrees, and the primary circuit cooling water would be heated to 600 degrees. At that time, water would be steam, and steam would be water, and the pressure would exceed 30 MPa. Ordinary steel in this environment would become a pile of discus in less than ten seconds.
However, the design life of an aircraft carrier reactor was as long as 30 years, and during this period, the fuel rod had been sealed in the ship and did not move.
What kind of fuel rod, what kind of pressure shell, could last for 30 years?
Even the United States could not do it.
After speaking, at the dinner table, Academician Liu and Zhou Yangwen suddenly looked at Ye Qing with a very strange and fiery look.
The United States could not do it …
It seemed that Monster Industries could give it a try. It seemed that if Hua Xia built a nuclear-powered aircraft carrier in the future, the pressure shell and fuel rod would most likely have to ask Monster Industries for help.
…
Late that night, Ye Qing returned to the Longxitan factory.
After the discussion, the monsters decided to get on board with the supercritical unit.
Academician Liu's information completely perfected the model designed by Dian Jing. Since there was no problem in theory, there was no problem in actual industrial processing.
