Monster Factory

Watanabe is too far away.

He came proudly, but with a full of unwillingness and deep fear, he left China.

On the plane, crossing the sun for too long can not be calm.

"If it is not the mobile phone business of the giant beast industry, and the business of the mine car is too profitable, I think that the most advanced industrial processing technology in our country will be the one of the giant beast industry, and there is no way to fight it." With my lips, there is some tremor in my speech.

In the scene of the living room of the guest house not long ago, the transfer of Fuyang Taichi thoroughly realized that the behemoth industry is unparalleled and powerful.

Fortunately, Behemoth Industry is just a company, not a country, and can take care of all industries in every aspect. If they don't get into the industrial processing robots and the machine tool market, then Duoyang thinks that he still resigned early, and it is better to go to the behemoth industry to eat rice.

"Teacher, I don't understand. The expert said that they have stacked seven special single crystal alloys. How do they do it? The properties and melting points of different metals are different and theoretically cannot be added together."

Du Fuyang looked at the disciple who did not understand and asked, and his eyes were bitter.

You ask me, who am I to ask?

In my heart, I thought that I was too vague to say: "Maybe they have a very special sintering technology, and the probe robot used inside the nuclear reactor does not need too high level of physical protection. The strength of the casing is not important, as long as it can Solve the effects of nuclear radiation."

"It’s too horrible, they claim that the shell protection ability is equal to 110 atomic numbers. Such data, I am afraid that only the United States can do it ten years later."

"I remember... The giant beast industry was founded less than two years ago?" Du Fuyang sighed too much. "It's a pity that everything is late. If you can know earlier that the behemoth industry holds this technology..."

"teacher……"

Another disciple intervened with some hesitation. "In fact, last year, we had a deal with the behemoth industry. At that time, they were also called the Beast Heavy Industry."

"We?" Du Fuyang immediately turned his head. "What do we mean?"

"It is our Japanese Polytechnic University." Another disciple of the mechanical engineering professor at the Japanese Institute of Technology, sighed with sighs. "Last year, our Japanese science and technology, and an academic exchange with Huaxia University in China."

"We wanted to promote Huawei, with a super-high-precision bolt, and it was difficult to go to Zhongyun University. The final result is similar to today."

"Zhongyun University urgently invited the young president of Behemoth Industry to become a foreign aid. He used to be a student at Zhongyun University and said that he was a graduate student. Then, the young president took a nut and took it in only two days. I have to know that even we are not very sure to put a nut out, he actually caught a hand."

Later, they sent us a steel ruler at the University of Science and Technology, asking us to engrave on it. ”

Watanabe was too shocked: "I did technical research on Fukushima last year. Why didn't I hear you say this?"

"Is that word engraved?"

The disciple twisted and pinched for a long time, and finally he did not say a word.

"The thing last year was too shameful, I...we, where will it be promoted everywhere?" After that, he took out his mobile phone from his pocket and transferred a picture. Du Fuyang looked at the picture intently, and there was a black iron ruler on the back of the picture, which attracted him all his heart.

Watanabe too knows that the front of the iron ruler has engraved the word "friendship for a long time", the young president, let them engrave [the teacher of the hundred]. Of course, these four words can't be engraved. It is equal to acknowledging that Huaxia is their teacher. But the Japanese Polytechnics also have to engrave to prove their own behavior, any four words, otherwise the skills are not as good as people, not what is the student?

As a result, Watanabe too saw the top of the iron ruler, and there were several nicks that twisted and twisted. These nicks have traces of laser burning, as well as sparks, and traces of plasma cutting, as well as two traces of the doorway that he temporarily does not see.

But these nicks are not words at all, nor are they the same equipment.

It seems that the University of Science and Technology has tried almost all the methods and has not succeeded in finding a way to write words.

Ferry is too cold to breathe.

......

At the same time, Ye Qing also got the much needed core and cooling water data.

Academician Liu himself is a top expert in domestic nuclear reactors. He is familiar with the knowledge of these nuclear energy theories.

He told Ye Qing that the aircraft carrier reactor and commercial power plant reactor technology are the same, but in actual use, the core parameters will be very different. The biggest difference is the difference in the concentration of uranium 235 in the core.

For commercial commercial nuclear power plants, the purity of core uranium 235 is only 3% to 6%, and the fuel needs to be changed every year.

However, the core used by the US aircraft carrier is directly removed from the retired nuclear warhead. The concentration of uranium 235 is over 95%. It can work continuously for 30 years and has more powerful power.

Academician Liu told Ye Qing that if Huaxia manufactures a nuclear-powered aircraft carrier, the concentration of uranium 235 in the core is at most 60% to 80%. Because the higher the uranium 235 concentration is, the higher the capital cost will be.

The United States created a large number of nuclear warheads during the Cold War. After the nuclear warheads were retired, the Navy simply recovered the nuclear power fuel core used as a warship. Without this historical accumulation, China will naturally be unable to imitate the United States, which is rich in wealth. Academician Liu also told Ye Qing that after the Cold War, the United States sealed thousands of tons of weapon-grade uranium; enough of those warships used for more than a thousand years.

Using weapons-grade uranium as a core is a very extravagant and highly advanced technology.

Fortunately, the core theory of weapon-grade uranium is not complicated, and it is only difficult to be industrially capable.

The last question, at noon Ye Qing and Academician Liu, at the guest house, chatted and asked why the US aircraft carrier reactors were all equipped with ordinary steam turbine units, not supercritical or even super-supercritical.

The latter laughed and said that this was related to core manufacturing technology.

Even the United States, which is strong in the world, is not sure to produce qualified core materials.

For example, Academician Liu said that a fuel pellet in a warship reactor core is only one centimeter long and one centimeter wide, but it can release energy equivalent to hundreds of tons of coal. Numerous fuel pellets are loaded into the fuel rod. When fission is performed, the internal temperature of the fuel rod is usually maintained at 700 to 800 degrees. However, the fuel rod is directly in contact with the primary circuit cooling water, and the cooling water is heated to three hundred degrees. Fuel rods made of special alloys will work in an underwater environment with different internal and external temperatures for a long time.

The temperature inside and outside is different, and it is necessary to accept the high temperature for a long time. The material properties of the metal will be greatly tested. If the battery is broken, the fuel rod will break and break. When the Fukushima Power Station caught fire, it was because of the failure of the primary circuit cooling system that the cooling water level dropped, and it was impossible to cover the entire fuel rod, and the upper half of the fuel rod was exposed to the air, and then the fuel rod broke.

The fuel rod is broken, which is directly the most serious nuclear accident at level 7. The consequences refer to Fukushima.

If you want to play supercritical, the internal temperature of the fuel rod will be as high as 1000 degrees, and the primary circuit cooling water will also change in essence.

Ultra-supercritical, it is 1200 degrees, the primary circuit cooling water is heated to 600 degrees. At that time, water is steam, steam is water, and the pressure exceeds 30 MPa. Ordinary steel in this environment will become a pile of discus in less than ten seconds.

It can be an aircraft carrier reactor with a design life of up to 30 years, during which the fuel rod is always closed in the ship.

What kind of fuel rod, what kind of pressure shell can last for 30 years?

Even the United States can't do it.

After that, at the dinner table, Academician Liu and Zhou Yangwen suddenly saw Ye Qing with a very strange and hot look.

Americans can't do it...

It seems that the giant beast industry can try it. It seems that if Huaxia builds a nuclear-powered aircraft carrier in the future, the pressure-resistant shell and fuel rods will most likely find the giant beast industry to help.

......

Late at night, Ye Qing returned to the Longxitan factory.

After the discussion, the monsters decided to go to the super-supercritical unit.

Academician Liu’s information completely refined the model of the electro-crystal design. Since the theory is no problem, the actual industrial processing is no problem.

The giant beast industry, a leader in the processing capacity is higher than the technical theory.
