Monster Factory - 788

In Ye Qing’s vision, the two nuclear reactors in front of him represent the highest level of industry.

The key equipment 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 the two hands of the electric crystal are connected, the sealing shell on the drawing is removed.

Ye Qing and the monsters discovered that there were two other sealed shells inside the sealed shell.

They have a flat cylindrical shape and are stacked on top of each other.

The upper sealed shell is covered with thick metal rods. These metal rods are fixed inside the sealed shell, a total of 480 pieces. There are no metal rods 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 physical drawings, Ye Qing can easily guess that this reactor is divided into two core parts.

Above is the fuel rod, and below is the circulating cooling system.

The circulation 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, gradually cool down, and rejoin the circulation process.

It sounds simple.

Fuel rods generate a lot of heat, which heats up the liquid, which is simply water.

Someone once joked that no matter how many generations of reactors have been developed, 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 if it is claimed that there will never be twenty-five years away from success, the controlled nuclear fusion that breaks the laws of physics will eventually still be used to generate electricity by burning hot water.

But it cannot be said that “boiling hot water” is very earthy. Among the thermal energy conversion known to mankind, the efficiency of boiling water is currently the highest.

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 the 480 fuel rods are not the same for each.

For fuel rods arranged in a hexagonal shape, if thousands of uranium-235 pellets are loaded in the outermost fuel rod, only 600 are loaded in the middle fuel rod, and their number arrangement is also very regular.

In doing so, Ye Qing guessed that it was to pursue the consistency of thermal energy.

If there is no drawing, the giant animal industry here wants to find the most perfect fuel pellet arrangement, I am afraid that it will have to go through many tests and verifications, consume a lot of resources, and accumulate a lot of data before it can finally be simulated by Supercomputing. And now, all you need to do is to paint a gourd.

There is also the working method of the cooling circulation 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 to 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. The Longxitan plant 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 control of supercritical unit manufacturing technology, it is clear that the United States is the largest country. Why are ordinary units that are at least two generations behind of technology used conservatively on such an advanced reactor?

There must be a reason.

To make the circulating water reach a supercritical state is very simple, just increase its residence time around the fuel rods.

The fuel rods generate 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 choose, you must not talk about supercritical or even ultra-supercritical units.

The Americans dare not go.

Among them, is it because the metallurgical industry technology does not pass the test? Or is it the natural limitation of the fuel rod itself?

If it’s the former, then Ye Qing doesn’t mind letting Americans see what is the world’s top industrial technology. They can’t do it. Giant Animal Industry will show them what is ultra-supercritical and what is infinite surging power.

If it is because of the latter, then the giant animal industry can only adopt the same conservative plan as the United States.

…

All night, the monsters were analyzing the hard-won three-dimensional drawings of the aircraft carrier reactor. All the details were meticulously memorized, and Dianjing transplanted this set of drawings into the supercomputing, using the complete drawings, and the existing metallurgical technology of the Giant Animal Industry, to establish a set of calculation models on the supercomputing.

For example, the drawings cannot show which alloy technology the Americans used to build the sealed pressure shell on the outermost periphery of the reactor.

But the giant animal industry knows to make it by itself, and it can make a shell that can withstand the highest pressure.

Similarly, the pressure of the primary circuit cooling pipe of the circulation 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 still unclear. 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 purely theoretical data. China is also a nuclear power. Large nuclear power plants have reached the mature third generation, maintaining the same leading level as the world. Perhaps limited by industrial processing technology, it is impossible to produce reactors for surface ships.

But what kind of core to use, how to stabilize the core, or why the United States does not use supercritical units, can all get answers from nuclear energy system workers.

Zhongyun University does not have a nuclear energy department, but several universities of science and technology in Shanghai do.

Many of the professors inside have participated in the design and R&D of China Nuclear Power Plant. They are people who have both theory and practical work experience. In the name of the company, hire them to improve the parameters of the material rods and cooling circulating water in the model built by Dianjing. Don’t be too easy.

Moreover, it is not illegal to provide only these internationally-used data, and they do not know whether the giant animal industry wants to build a reactor or the world’s most advanced marine reactor from the United States.

Early the next morning, 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 the Department of Mechanical Engineering, he was in the circle of professors and lived a lot of years. He has connections all over the country. It is not wrong to ask him to recommend a few professors in the field of nuclear energy.

After receiving the call from Ye Qing, Professor Cai Chenning didn’t think for too long, before letting out a series of firecracker-like laughs.

“Mr. Ye, you are asking the right person when you ask me.”

“Listen to me, you don’t have to find a bunch of professors to study theoretical data. Researching nuclear energy is not about playing mahjong. It’s useless if there are too many people.”

“I recommend a super’big cow’ to you. He is enough. He has the ready-made data you want.”

Ye Qing asked a little anxiously who this’big cow’ was, wouldn’t he be a national treasure-level academician? This kind of people seems to be busier than the president, so it’s not easy to move, right?

“Haha~ President Ye, don’t worry. If this’big cow’ wants to talk about other companies, he really doesn’t want to move, but your behemoth industry is just fine.”
