Monster Factory Chapter 784: : Ultra-supercritical unit
Watanabe Yota is gone.
He came with pride, but with full of unwillingness and deep fear, he left China.
On the plane, Watanabe Yota couldn't calm down for a long time.
"If it weren't for the cell phone business of Monster Industry, and the Swift Thunder automobile business to make money too much, I think our country's most cutting-edge industry processing technology will be beaten by the Monster industry, and there will be no fight back." Watanabe Yota covered her lips, There was some tremor in the words.
The scene that happened in the reception room not long ago made Watanabe Yota completely realize that the Monster industry is unparalleled and powerful.
Fortunately, Monster Industry merely, a Company, is not a country and can take care of all industries in all aspects. If they plunge into the industrial processing robots and machine tools markets and fail to come out, then Watanabe Yota feels that they should resign early and come to the Monster industrial mixed meal to eat better.
"Teacher, I don’t understand. The expert said that they stacked seven special monocrystal alloys together. How did they do it? Different metals have different properties and melting points, so theoretically they cannot be stacked together." /
Watanabe Yota 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 this in my mind, Watanabe Yota said vaguely: "Maybe they have mastered the very special sintering technology, and the detection robot used in the nuclear reactor does not need too high level of physical protection. The shell strength is not important. It can solve the impact of nuclear radiation then it will be alright."
"It's too terrifying. They claim that the shell protection ability is equal to 110 atomic number. Such data, I am afraid that only USA in ten years can do it."
"I remember...the Monster industry has been established for less than two years, right?" Watanabe Yota sighed, "Unfortunately, everything is too late. If you can know that Monster industry has this technology..."
"Teacher..."
Another disciple interjected a little hesitantly, “In fact, we had a deal with Monster Industry last year. At that time, they were still called Monster Heavy Industry.”
"Us?" Watanabe Yota immediately turned his head, "What do we mean?"
"It's our Japanese University of Science and Technology." Another student of Professor in mechanical engineering at Japanese University of Science and Technology, he sighed heavily, "Last year, our Japanese University of Science and Technology held an academic exchange with China Zhongyun City University."
"We originally wanted to raise the China and use a super high precision bolt to stump the Zhongyun University. The final result is similar to today."
"Zhongyun University urgently invited the young president of Monster industry to be a foreign aid. He used to be a Zhongyun University student and said he was in graduate school. Then, the young president took a handful of nuts in only two days. You know. Even us, we are not too sure to match a nut out, he actually grabbed one."
Later, they gave us an iron ruler at Nikkei University, asking us to engrave on it. "
Watanabe Yota was shocked: "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, but finally he said no.
"That incident last year was too embarrassing, I...Where would we advertise it everywhere?" After speaking, he took out the cell phone from his pocket and transferred a picture. Watanabe Yota looked at the picture intently. In the picture, there was a black iron ruler on the back, which attracted all his attention.
Watanabe Yota knew that [Friendship For All Time] was engraved on the front of the iron ruler. The young president asked them to engrave [Master Of A Hundred Lifetimes]. Of course these four characters cannot be engraved. Engraving is equivalent to admitting that China is their teacher. But 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 several crooked marks on the iron ruler. These nicks have laser burn marks, electric sparks, and plasma cutting marks, and there are two other marks that he can't see the doorway temporarily.
But these notches are not words at all, nor are they made by the same device.
It seems that Nikkei University has tried almost every method, but failed to find a way to engrave characters.
Watanabe Yota sucked in cold air again.
……
At the same time, Ye Qing also got the much-needed information on the core and cooling water.
Academician Liu itself is a top expert in domestic nuclear reactors, and he is familiar with these nuclear energy theories.
He told Ye Qing that the aircraft carrier reactor and the commercial power plant reactor have the same technical principles, but in actual use, the core parameters will be very different. The biggest difference in this difference lies in the Uranium-235 concentration in the core.
ordinary commercial nuclear power plant, the purity of the core Uranium-235 is only 3% to 6%, and the fuel needs to be changed once a year.
However, the core used by USA aircraft carrier is a weapon-grade uranium disassembled directly from a decommissioned nuclear warhead. The concentration of Uranium-235 exceeds 95%, and it can work continuously for 30 for years, and the power is more powerful.
Academician Liu told Ye Qing that if China produces nuclear power aircraft carrier, the core Uranium-235 concentration is at most 60% to 80%. Because the higher the concentration of refine Uranium-235, the higher the capital cost.
USA produced huge volume nuclear warheads during the Cold War. After these nuclear warheads were retired, navy simply recovered the nuclear power fuel core used as military vessel. Without this historical accumulation, China naturally cannot imitate the wealthy USA. Academician Liu also told Ye Qing that after the Cold War, USA had sealed up thousands of tons of weapon-grade uranium; enough for military vessel to be used 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 industrial manufacturing capabilities.
Last question, when Ye Qing and Academician Liu were eating at the guest house at noon, they chatted and asked why the USA aircraft carrier reactor was equipped with ordinary steam turbine units instead of supercritical or even ultra-supercritical.
The latter is heartily laughed, saying that it is related to the core manufacturing technology.
Even USA, which is as powerful as World First, is not sure to produce qualified core materials.
Academician Liu gave an example, a fuel pellet in the military vessel reactor core 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. But the fuel rod directly contacts the primary circuit cooling water, heating the cooling water to three Baidu|numerous. Fuel rods made of special alloys, President can work in an underwater environment with different internal and external temperatures.
The internal and external temperatures are different, and long-term high temperature effects are required. The material properties of metal will be tested by immense. 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 fracture occurred.
The fuel rod fracture is directly the most serious nuclear accident at level 7, and the consequences can 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 change essentially.
Ultra-supercritical, it is 1200 degrees, and the primary circuit cooling water is heated to 600 degrees. At that time, water is steam, steam is water, and the pressure exceeds 30 megapascal. In this environment, ordinary steel will turn into 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 this period, the fuel rods have been enclosed in the ship without moving~IndoMTL.com~ What kind of fuel rods and pressure shells can last 30 years ?
Not even USA can do it.
After finishing speaking, Academician Liu and Zhou Yangwen at the dinner table suddenly looked at Ye Qing with strange and fiery eyes.
USA people can’t do it...
It seems that the Monster industry can give it a try. It seems that if the China builds a nuclear power aircraft carrier, the pressure shell and fuel rods, most of them have to ask the Monster industry for help.
……
Late night that night, Ye Qing returned to Dragon Creek Beach Factory.
After the discussion, the monsters decided to launch an ultra-supercritical unit.
The information of Academician Liu makes the model designed by Electric Crystal completely perfect. Since the theory is fine, the actual industry processing is also fine.
Monster industry, an item that is at the forefront of processing capability higher than technical theory.
