Monster Factory

Watanabe Yang is gone.

He came proud, but left Huaxia with a deep sense of frustration and deep fear.

Watanabe Yang has been on the plane for too long to calm down.

“If it weren't for the mobile business of the giant animal industry and the torpedo automotive business, I think the most sophisticated industrial processing technology in our entire country would have been beaten by the giant animal industry.” The Watanabe sun covered his lips and his words were shaking.

A recent scene in the living room of the reception hall made the Watanabe Sun fully realize that the giant animal industry is unparalleled and powerful.

Fortunately, the giant animal industry is just a company, not a country, and can accommodate all sectors. If they are stuck in the industrial processing robot and machine tool market, the Watanabe Sun thinks it would be better to resign early and come to the giant animal industry to mix meals.

“Teacher, I don't understand. The expert said how did they do that by stacking seven special single crystal alloys together? Different metals perform differently from melting point to point and cannot theoretically be superimposed together. ”

Watanabe Sun glanced at the disciple who did not understand and asked, his eyes were bitter.

Ask me, who am I asking?

In my mind, Watanabe Sun's mouth is vague: “Perhaps they possess a very special sintering technique, and the probing robot used inside the nuclear reactor does not need a very high level of physical protection, the shell strength is not important, as long as it can solve the effects of nuclear radiation. ”

“It's horrible, they claim that shell protection equals 110 atomic numbers. I'm afraid it's only 10 years from now that the United States can do this. ”

“I remember... the giant animal industry was founded less than two years ago, right?” The Watanabe Sun sighed. “Unfortunately, it's too late. If we had known sooner, Giant Beast Industries would have mastered this technology...”

“Teacher...”

Another disciple interrupted with hesitation, "Actually, last year, we had an affair with the giant animal industry. Back then, they called the Beast Heavy Industries. ”

“We?” The Watanabe Sun immediately turned its head, “What do we mean? ”

“is our Japanese Polytechnic University.” Another disciple who was a professor of mechanical engineering at Nippon Polytechnic sighed heavily, "last year we held an academic exchange with Nippon Polytechnic and Zhongyun University in Huaxia. ”

“We were going to Yang Weihua Xia, with an ultra-high precision bolt, and it was difficult to pour down Zhongyun University, and the final result was similar to today's. ”

“Zhongyun University urgently invited the young president of the giant animal industry to become a foreign aid. He was a student of Zhongyun University and said he was a graduate student. Then the young president grabbed a nut in just two days. You know, even we weren't so sure with a nut, he actually caught one. ”

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

Watanabe Sun was stunned: “Last year I did a technical assault on Fukushima's side. Why didn't I hear you say this? ”

“Is that engraved? ”

The disciple twisted and squeezed for half a day before finally holding out a single sentence.

“Last year was so embarrassing, I... where else would we spread the word?” After that, he pulled his phone out of his pocket and turned a picture out. The Watanabe Sun looked at the picture without turning a blind eye. In the picture, there was a black iron ruler on the back that attracted all of his mind.

The Watanabe Sun knows that the front of the Iron Ruler is engraved with the words "Friendship for a long time". The young president asked them to engrave the words "Master of the Hundreds". These four words, of course, cannot be engraved, which is tantamount to acknowledging that Hua Xia is their teacher. But Nikkei also has to engrave to prove that he can do it. Whatever the four words, otherwise the skill is worse than that of a person, not a student what is it?

As a result, the Watanabe Sun saw several twisted marks on the iron ruler. These marks show laser burns, electric sparks, and plasma cuts, and two other types that he can't see for the time being.

But these marks are not words at all, nor are they the same device.

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

The Watanabe Sun sucked in the cool air again.

……

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

Academician Liu himself is the leading expert in nuclear reactors in the country, and he is familiar with the knowledge of these nuclear theories.

He told Ye Qing that aircraft carrier reactors and commercial power plant reactors had the same technical principles, but in practice, core parameters would vary greatly. The biggest difference is in the concentration of uranium 235 in the core.

In general commercial nuclear power plants, the core uranium-235 is only 3 to 6 per cent pure, and fuel needs to be changed every year.

The core used by United States carriers, however, is weapons-grade uranium dismantled directly from decommissioned nuclear warheads, with uranium-235 concentrations exceeding 95 per cent, capable of working continuously for 30 years and with greater power.

Maester Liu told Ye Qing that if Huaxia manufactures a nuclear power carrier, the uranium 235 concentration of the core is up to 60-80%. The higher the upward purification of uranium 235, the higher the financial cost involved.

The United States manufactured a large number of nuclear warheads during the Cold War, which, when decommissioned, were simply withdrawn by the Navy as nuclear power fuel reactors for warships. Without this accumulation of history, Huaxia will naturally not be able to imitate the rich and rugged United States. Liu also told Ye Qing that after the Cold War, the United States had stockpiled about thousands of tons of weapons-grade uranium; enough for those warships to last more than a thousand years.

The use of weapons-grade uranium as a core is a very luxurious and very advanced technology.

Fortunately, the core theory of weapons-grade uranium is not complicated, it is difficult only in terms of industrial manufacturing capacity.

One last question, when Ye Qing and Liu Academician were eating at the hostel at noon, they chatted about why the American Aircraft Carrier Reactor was paired with a regular steam turbine unit, not a supercritical, or even supercritical.

The latter laughed laughingly, saying that it was related to core manufacturing techniques.

Even the strongest America in the world is not sure to make qualified core materials.

For example, one fuel core in a warship reactor core is only a centimetre long and a centimetre wide, but it can release energy equivalent to hundreds of tons of coal. Countless fuel cores, loaded in fuel rods. The internal temperature of the fuel rod is typically maintained at 700 to 800 degrees while the fission is taking place. However, the fuel rod is in direct contact with a circuit of coolant, heating the coolant to 300 degrees. Fuel rods made of special alloys work in an underwater environment with varying internal and external temperatures for a long time.

Different internal and external temperatures are subject to high temperatures for a long period of time. The material performance of the metal will undergo a huge test. If it is slightly inadvertent, the fuel rod will break. The fire at Fukushima Power Station was caused by the failure of a circuit cooling system, which caused the cooling water level to drop, unable to cover the entire fuel rod, exposing the upper half of the fuel rod to air, and then the tragedy of the fuel rod breaking.

The breakdown of the fuel rod was the most serious nuclear accident of Class 7, and the consequences were referred to Fukushima.

If you want to play ultra-critical, the internal temperature of the fuel rod will be as high as 1000 degrees and a circuit of coolant will change essentially.

Ultra-supercritical, it takes 1,200 degrees, and one circuit of coolant is heated to 600 degrees. Water is steam, steam is water, pressure is over 30 MPa. Normal steel in this environment turns into a pile of iron cakes in less than ten seconds.

A carrier reactor has been designed for a period of up to 30 years, during which time the fuel rods remain sealed in the ship.

What kind of fuel rod, what kind of pressure-resistant shell, will last 30 years?

Not even the United States can do that.

After that, at the dinner table, Liu Academicians and Zhou Yanwen suddenly looked at Ye Qing with a very strange and hot look.

Americans can't do it...

It seems that the giant animal industry can try it. It seems that if Huaxia were to build a nuclear-powered aircraft carrier in the future, it would probably have to get help from the giant animal industry for the crust resistant shells and fuel rods.

……

Late that night, Ye Qing returned to Longxi Beach Factory.

At the end of the discussion, the monsters decided to board the super-supercritical Unit.

Professor Liu's data makes the model of the crystal design complete. Since the theory is fine, the actual industrial processing is also fine.

Giant animal industry, one of the forerunners of higher processing capacity than technology theory.
