Monster Factory Chapter 778: : Please Daniel
In Ye Qing’s vision, there are two represented nuclear reactors with the highest level in the industry.
The key device, which is hidden in the sealed shell, may be very precise and compact. It is not an exaggeration to describe it as a dojo in a snail shell. When Electric Crystal connects his hands and removes the sealing shell on the drawing.
Ye Qing and the monsters discovered that there were two other sealed shells inside the sealed shell.
They are flat and cylindrical, stacked on top of each other.
In the above sealed shell, there are thick metal rods inside. These metal rods are fixed inside the sealed shell, a total of 480 pieces. There is no metal rod in the lower sealing shell, but there are many pipes. The upper part of these pipes is connected with the overhead sealing shell, and the lower part extends to the outside, and finally is connected with the steam turbine.
If you only look at the body building drawings, Ye Qing can easily guess that this reactor is divided into two core parts.
On the top is the fuel rod, and below is the circulation cooling system.
Circulating system continuously takes away the high-pressure heat flow around the fuel rods. These heat flows exchange heat with the water in the secondary circuit, drive the steam turbine to rotate, and after gradually cooling down, it is added to the circulation process again.
It sounds simple.
The fuel rod generates a lot of heat, and this heat heats the liquid, which is simply water.
Someone once joked that no matter how many generations of reactors are developed and what high technology is used, they still cannot get rid of the problem of boiling hot water. When will we get rid of this point, it will be regarded as real technological progress.
This seems to make sense. Even though it is claimed that there will always be 20 five years away from success, the controllable nuclear fusion that breaks the laws of physics will still boil hot water to generate electricity.
But it cannot be said that "boiling hot water" is very earthy. Among the thermal energy conversion known to mankind, boiling water is currently the most efficient.
The technical difficulty of boiling hot water in a nuclear reactor is not at all imaginable. It is simple to make it boil hot water, but how to make it always boil hot water steadily and perform the combined cycle safely and stably is the real difficulty. Otherwise, in the event of a nuclear leak, the only outcome of the entire ship is to be sunk to the bottom of the sea.
The reactor drawings on the screen were enlarged a little bit. Soon, Ye Qing and the monsters discovered many extraordinary details from these seemingly ordinary core structures.
For example, the reactor fuel pellets contained in these 480 fuel rods are not all the same.
Hexagonal arrangement of fuel rods. If thousands of Uranium-235 pellets are loaded in the outermost fuel rods, only 600 of them are loaded in the middle fuel rods, and their numbers are arranged regularly. .
In doing so, Ye Qing guessed that it was to pursue the consistency of thermal energy.
If there is no drawing, the Monster industry wants to find the most perfect fuel pellet arrangement. I am afraid that it will have to go through many experiments and verifications, consume huge volume resources, and accumulate a large amount of data before Super Computer can finally be simulated. And now, all you need to do is to draw a gourd.
There is also the working mode of the cooling cycle system below, which is enlarged with the drawing. Ye Qing and the monsters, following the cyclic structure tracking analysis, it is easy to infer the power generation mode of this reactor from the structure of this system.
The primary circuit cooling water, which conducts heat into the secondary circuit water of the steam turbine for power generation, is not in a supercritical state.
Supercritical units are very different from ordinary steam turbine units. Dragon Creek Beach Factory has produced supercritical units here, so naturally I know this very well. It is not supercritical, which proves that the heat efficiency ratio of this reactor is not high.
If the supercritical unit can have a heat efficiency ratio of 50%, the heat efficiency ratio of the current set is at most 30%.
Ye Qing is a little strange. Although only a few major countries have the technology for supercritical unit manufacturing, it is clear that USA is the largest country. Why is still conservatively adopting the ordinary unit which is at least two generations behind on such an advanced reactor?
There must be a reason.
It is very simple to make the circulating water reach the supercritical state, just increase its residence time around the fuel rods.
The fuel rod generates heat during the chain reaction process to heat the water in the pressure shell. Without cooling, the temperature of the fuel rod can rise to more than two thousand degrees. The critical temperature of water is only 374.15 degrees, and Ye Qing estimates that the steam working temperature of this unit is at most 300 degrees.
The difference is only more than 70 degrees, but the heat efficiency ratio is very different. If you let yourself be choice, you must not talk about supercritical or even ultra-supercritical units.
USA people are afraid to go.
Among these, is it because the metallurgy industrial technology is not good enough? Or is it the natural limitation of the fuel rod itself?
If it's the former, then Ye Qing doesn't mind letting USA know what is the world's top industrial technology. They can't do it. Monster Industry will show them what is ultra-supercritical and what is infinite power.
If it is because of the latter, then the Monster industry can only adopt the same conservative plan as USA.
……
All night, the monsters were analyzing the hard-won 3D drawings of the aircraft carrier reactor. All the details have been meticulously memorized. Electric Crystal transplanted this set of drawings to Super Computer, using the complete drawings, and Monster's existing metallurgy technology, to establish a set of calculation models on Super Computer.
For example, the drawings cannot show the USA people and which alloy technology is used to build the outermost sealed pressure shell of the reactor.
But the Monster industry knows that it can manufacture it by itself, and it can produce a shell that can withstand the highest pressure.
Similarly, the pressure of the primary circuit cooling pipe of the system and the maximum working pressure of the secondary circuit can be expressed in a very specific model.
Of course, these data alone are not enough. The specific formula of the core in the fuel rod is not clear, and what kind of catalyst or passivator is added to the cooling circulating water to stabilize the chain reaction process of the fuel rod. ?
However, these data are no longer a stumbling block.
The core structure is cracked, and the remaining unknown parameters are pure theoretical data. China is also a nuclear power. Large nuclear power plants have developed to the mature third generation, maintaining the same leading level as the world. Perhaps limited by the industrial processing technology, it is impossible to produce reactors for surface ships.
But which kind of core is used, how to stabilize the core, or why USA does not use supercritical units, can all get answers from the nuclear energy system workers.
Zhongyun University does not have a nuclear energy department, but several universities in Shanghai do.
Many of the Professor insiders have participated in the design and research and development of China nuclear power plants. They are people who have both theory and practical work experience. In the name of Company, hire them to perfect the parameters of the material rod and cooling circulating water in the model established by Electric Crystal. Don't be too easy.
Moreover, it is not illegal to provide only these international data. They do not know whether the Monster industry will build a reactor or the world's most advanced marine reactor from USA.
The next morning~IndoMTL.com~ Ye Qing called Professor Cai Chenning of Zhongyun University.
Professor Cai Chenning was Ye Qing's mentor when he was in college. Although he was in charge of Mechanical Engineering Department, he was in the Professor circle, and he lived a lot of years, with contacts all over the country. It's not wrong to ask him to recommend a few Professor in the nuclear energy field.
After receiving a call from Ye Qing, Professor Cai Chenning didn't think about it for too long, and then let out a series of firecracker laughs.
"Mr. Ye, when you ask me, you are asking the right person."
"Listen to me, you don't need to find a bunch of Professor to study theoretical data. Researching nuclear energy is not about playing mahjong, so many people are useless."
"I recommend a Exceed Grade ‘Da Niu’ to you. He is enough. He has the ready-made data you want."
Ye Qing asked a little nervously who is this ‘big cow’, wouldn’t he be a national treasure academician? This kind of people seems to be busier than the president, so it's not easy to please move?
"Haha ~, Mr. Ye, don't worry, this'big cow' wants to talk about other companies, so please don't move, but your Monster industry is just fine."
