"Let's start with the steam generator."

A steam generator is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam.

To put it bluntly, whether it is conventional power or nuclear power, it is essentially a process of boiling water.

It's just that the way to boil water is different.

Xu You first designed the sketch of the steam generator in the computer according to the request of the code name Wu.

According to the demand, this steam generator needs to be responsible for the heat exchange of the primary and secondary circuits.

While designing, Xu You is also deriving related formulas.

"The working medium on the side of the primary circuit is coolant, and the coolant pipeline is divided into multiple nodes along the flow direction, which need to satisfy the mass conservation equation and energy conservation equation..."

After focusing on the design of the model and the derivation of the formula.

The whole process is an extremely complicated physics problem.

But this is completely different from the questions Xu You did when he was in school.

The investigation of those topics is relatively simple, and many conditions are directly ignored. It only needs to be analyzed according to the ideal model.

However, in actual design, all problems must be considered, and those conditions cannot be idealized directly.

Another difficulty is that there are not many reference plans for the design of nuclear power plants for nuclear aircraft carriers in China.

Most of these internal data are the nuclear power plants of some nuclear submarines, as well as some fragmented data about the beautiful national nuclear aircraft carrier.

These fragmented data, because of the way they are obtained, cannot guarantee the complete accuracy of the data.

Xu You must clearly distinguish whether these materials are correct or not, so as to help him design the nuclear power plant of the aircraft carrier.

In this way, another ten days passed.

Xu You completed the design of dozens of model diagrams, deduced related theoretical formulas, and wrote several notebooks.

The mathematical model of the entire set of nuclear power equipment has finally completed the preliminary design.

In these ten days, Xu Youming spent more than one hundred hours on the surface, but in fact, he has spent hundreds of hours in the state of deep learning.

Many of them are more efficient flow states.

It can be said that the design of each small model and the derivation of each formula contain Xu You's full of hard work.

With the mathematical model they made, Xu You, Fan Haisheng and others started another round of meetings.

"Professor Xu, have you really established the mathematical model of nuclear power equipment so quickly?"

They all expressed their amazement at Xu You's speed.

Even for a team, it is difficult to complete the design of such a level model in such a short period of time.

It seems that what they said, that Xu You can beat an elite team by himself, is not just talking.

"Well, the first version of the mathematical model has been prepared."

Although Xu You is very confident in his mathematical model.

But before the model has been verified, Xu You still has to leave some leeway for himself.

Next, Xu You explained some key contents of the model.

Talking about the model from beginning to end, I don't know how many days it will take.

But just the key part of it, Xu You also spent several hours explaining it.

"The K value here can be obtained according to the principle of cylinder heat transfer. The Rw among them is obtained from the formula of the heat conduction resistance of the tube wall. The heat transfer of the working fluid on the primary side and the subcooling section on the secondary side is single-phase heat transfer. , the heat transfer coefficient is calculated according to the Dittus-Boelte formula. The heat transfer of the working fluid in the secondary side boiling section is flow boiling heat transfer, and the heat transfer coefficient can be calculated using the Rohsenow formula..."

As the chief designer codenamed Wu, Fan Haisheng also tried his best to keep up with Xu You's train of thought.

As for the other designers and engineers, because they were responsible for different tasks, they could not fully understand many of Xu You's explanations, so they could only bite the bullet and listen.

Whether you understand it or not, you can see that Xu You's nuclear power plant model is really not simple.

However, as for whether this set of nuclear power plant models can really be applied to aircraft carriers, no one can draw a conclusion at this time.

"If we can get the actual ship data of the beautiful national nuclear aircraft carrier, it can help us verify the nuclear power plant model. Unfortunately, we do not have their complete nuclear aircraft carrier actual ship data."

All countries will strictly keep this level of data confidential.

At this time, Fan Haisheng said:

"My idea is to use the land-based model reactor for verification. If there is no problem with the land-based model reactor, we will build a technology verification ship. If everything goes well, it will eventually be applied to nuclear submarines."

A nuclear reaction power plant in the theoretical stage will certainly not be directly applied to a nuclear aircraft carrier, but requires multiple verification processes.

Among them, the first verification is often in the form of land-based model piles.

The land-based model reactor, as a test facility for the development of reactor technology, can be used to test the overall technology and special technology of the reactor, and to carry out test verification of new reactors and their systems, equipment and components.

This is also an experimental method used by the beautiful country in the process of researching nuclear aircraft carriers.

However, the locations where onshore model stacks are established are often relatively remote inland areas.

After all, even a model reactor is a real nuclear reactor.

Once a nuclear reactor accident occurs, the consequences are very serious.

Establishing land-based model reactors in areas with fewer people can avoid risks to the greatest extent while reducing possible radiation pollution.

At the same time, the location of the land reactor, the traffic is best not to be too far behind.

Otherwise, shipping is also a problem.

At this time, Xu You said:

"I agree with Mr. Fan's idea. I am also willing to go to the location of the onshore model reactor and participate in the experiment of the onshore model reactor."

Hearing Xu You's words, everyone in the conference room had a surprised expression.

Xu You, you want to take the initiative to participate in the experiment of the land-based model reactor?

This is a very dangerous experiment!

Xu You's current value is that of a national treasure in the entire country, and he cannot tolerate any mistakes.

"Professor Xu, I can't let you go to the scene. If you make a slight mistake, we can't bear such responsibility."

Now Xu You's identity is still a professor of Ji University.

Participating in this project is not Xu You's obligation, but Xu You's voluntary participation.

If this Nobel Prize winner in physics, who was only in his early twenties, was harmed by a dangerous experiment, the loss would be immeasurable.

"Mr. Fan, I have full confidence in safety control. If I dare not go to the scene myself, how can I let other operators go to the scene?"
