Monster Factory - 794

Watanabe Yang is too far away.

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

On the plane, Watanabe Yang could not be calm for too long.

“If it weren’t for the mobile phone business of the Giant Monster Industry and the Jilei Automobile business to make too much money, I think our entire country’s most cutting-edge industrial processing technology would be defeated by the Giant Monster Industry, and it would be impossible to fight back.” She pressed her lips, and her words trembled.

The scene that happened in the reception room not long ago made Watanabe Yang thoroughly aware of the incomparable strength of the giant beast industry.

Fortunately, Behemoth Industry is only a company, not a country, and can take care of all industries in all aspects. If they plunge into the industrial processing robot and machine tool market and fail to come out, Watanabe thinks that he should resign early, and it would be better to come to the Giant Monster Industry to eat.

“Teacher, I don’t understand. The expert said that they stacked seven special single crystal alloys together. How did they do it? Different metals have different properties and melting points, so theoretically they cannot be stacked together.”

Watanabe Yang glanced at this disciple who asked if he didn’t understand, his eyes were full of bitterness.

You ask me, who am I asking?

Thinking in this way, Watanabe Yang said vaguely: “Maybe they have mastered a very special sintering technology, and the detection robot used in the nuclear reactor does not require high-level physical protection. The strength of the shell is not important, as long as it can Just solve the impact of nuclear radiation.”

“It’s horrible. They claim that the shell protection capability is equal to 110 atomic number. I am afraid that only the United States in ten years will be able to achieve such data.”

“I remember… Behemoth Industry was established less than two years ago?” Watanabe Yang sighed too much, “It’s a pity that everything is too late. If you could know that Behemoth Industry possesses this kind of technology…”

“teacher……”

Another disciple interjected a little hesitantly, “In fact, last year, we had a deal with Giant Beast Industry. At that time, they were still called Giant Beast Heavy Industries.”

“We?” Watanabe Yota immediately turned his head, “What do we mean?”

“It’s our Japanese University of Science and Technology.” Another disciple who was a professor of mechanical engineering at Japanese University of Science and Technology sighed heavily. “Last year, our Japanese University of Science and Technology held an academic exchange with China Zhongyun University.”

“We wanted to make a big splash in China and use an ultra-high-precision bolt to stump Zhongyun University. The final result is almost the same as today.”

“Zhongyun University urgently invited the young president of Giant Animal Industry to be a foreign aid. He was a student of Zhongyun University and said he was studying for a graduate student. Then, the young president grabbed a handful of nuts in just two days. You know that even us, we are not too sure to come out with a nut, he actually grabbed a handful.”

Later, they gave us an iron ruler at the University of Science and Technology, asking us to engrave on it. ”

Watanabe Yang was too surprised and said: “I did technical research in Fukushima last year. Why didn’t I hear you talk about it?”

“Has that character been engraved?”

The disciple twisted and squeezed for a long time, and finally he said no.

“That incident last year was too embarrassing, I…we, where would we advertise it everywhere?” After speaking, he took out his phone from his pocket and transferred a picture. Watanabe Yang stared at the picture too intently. In the picture, there was a black iron ruler on the back, which attracted all his attention.

Watanabe Yo too knew that the front of the iron ruler was engraved with the words “Long Friendship”. The young president asked them to engrave the “Master of a Hundred Generations”. Of course, these four characters cannot be engraved. Engraving is equivalent to admitting that Hua Xia is their teacher. However, Japanese science and technology also have to engrave to prove that they can do it, just any four words, otherwise the skills are not as good as people. What is it that is not a student?

As a result, Watanabe Yota saw a few crooked marks on the iron ruler. There are traces of laser burns, electric sparks, and plasma cutting of these nicks, and there are two other traces that he can’t see the doorway for the time being.

But these notches are not words at all, nor are they made by the same equipment.

It seems that Nikkei University has tried almost every method, but failed to find a way to engrave characters.

Yota Watanabe sucked in a cold breath again.

…

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

Academician Liu himself is a top expert on nuclear reactors in China, and he is very familiar with the knowledge of nuclear energy theory.

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

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

However, the core used by the US aircraft carrier is a weapon-grade uranium dismantled directly from a decommissioned nuclear warhead. The concentration of uranium 235 exceeds 95%. It can work continuously for 30 years and is more powerful.

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

The United States produced a large number of nuclear warheads during the Cold War. After these nuclear warheads were retired, the Navy simply took back the nuclear power fuel cores used in warships. Without this historical accumulation, China would naturally not be able to imitate the wealthy and wealthy United States. Academician Liu also told Ye Qing that after the Cold War, the United States had sealed up thousands of tons of weapon-grade uranium; enough for those warships to last for more than a thousand years.

Using weapon-grade uranium as the core is a very luxurious and very advanced technology.

Fortunately, the core theory of weapon-grade uranium is not complicated. It is only difficult in terms of industrial manufacturing capabilities.

The last question is that when Ye Qing and Academician Liu were eating at the guest house at noon, they chatted and asked why the US aircraft carrier reactors are equipped with ordinary steam turbine units instead of supercritical or even ultra-supercritical.

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

Even the United States, which is as powerful as the world’s largest, is not sure to produce qualified core materials.

Academician Liu gave an example, a fuel pellet in the reactor core of a warship is only one centimeter long and one centimeter wide, but the energy it can release is equivalent to hundreds of tons of coal. Numerous fuel pellets are loaded in fuel rods. During fission, the internal temperature of the fuel rod is usually maintained at 700 to 800 degrees. However, the fuel rod directly contacts the primary circuit cooling water, heating the cooling water to 300 degrees. Fuel rods made of special alloys will work in an underwater environment with different internal and external temperatures for a long time.

The internal and external temperatures are different, and long-term high temperature effects are required. The material performance of the metal will be greatly tested. If you are not careful, the fuel rod will break and break. The fire at the Fukushima Power Station that year was due to 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 the tragedy of the fuel rod rupture occurred.

A fuel rod fracture is directly the most significant level 7 nuclear accident. For 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 cooling water of the primary circuit will also undergo essential changes.

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. In this environment, ordinary steel will turn into a pile of discus in less than ten seconds.

However, an aircraft carrier reactor has a design life of up to thirty years, during which the fuel rods have been enclosed in the ship without moving.

What kind of fuel rod and what kind of pressure shell can last for thirty years?

Not even the United States can do it.

After speaking, Academician Liu and Zhou Yangwen suddenly looked at Ye Qing with strange and fiery eyes at the dinner table.

Americans cannot do…

It seems that the Giant Monster Industry can give it a try. It seems that if China builds a nuclear-powered aircraft carrier in the future, the pressure hull and fuel rods will mostly have to seek the help of the Giant Monster Industry.

…

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

After the discussion, the monsters decided to launch an ultra-supercritical unit.

The information of Academician Liu completely perfected the model designed by Dianjing. Since the theory is okay, the actual industrial processing is also okay.

The Giant Animal Industry is at the forefront of processing capacity higher than technical theory.
