A big country of aerospace with black technology

"Director, is this paper useless?"

The scientific research assistant took the paper that Zhang Xingyang had screened and put aside and said:

"I read this article when I was studying for my Ph.D., and I think their arguments on ultra-high temperature corrosion-resistant materials are quite useful."

The office that originally smelled like paint has been replaced by the smell of piles of old paper.

Mixed with a strong musty smell.

Even if the air purification system in the room is working continuously, it is difficult to remove the odor in the office.

"Let me see."

Zhang Xingyang took a document from his assistant, glanced at it and said:

"There are problems with this paper, it's just that they have never been taken down."

"It actually doesn't reach the strength of the data stated in their paper."

"We did an experimental reproduction of it three years ago."

"The results were actually only able to achieve 40 percent of their theoretical strength."

Although the scientific research assistant also has a doctorate from a top domestic university, he has only read this article.

No relevant experimental replication has actually been carried out.

In fact, even if they wanted to reproduce it, they didn't have the conditions.

The equipment required for the experiment is only available in a few domestic research institutes.

Zhang Xingyang recalled the scene at that time, "At that time, we wrote a letter to the journal and pointed out the errors in the article."

"But I didn't expect that they haven't withdrawn yet."

"I don't know if it's because the work efficiency is too low or if there are other reasons."

The scientific research assistant asked curiously, "Don't they say that Westerners are more efficient at work?"

The era of mobile Internet has just begun, and entertainment software such as TIKTOK has not yet been developed.

Chinese people always have a filter that makes it difficult for others to understand countries they have never seen before.

Only after the rise of short video platforms can we have a comprehensive and in-depth understanding of all aspects of other countries in the world.

Only then will you understand that many of the beautiful impressions in this world are just your own YY.

Zhang Xingyang said: "There are differences in work efficiency in the West. This is a John Bull journal. They only publish two issues a year."

"With their work efficiency, it is possible that the letter will be seen within two years and withdrawn within four or five years."

"After all, this is a country where it takes several months to apply for a bank card."

For a moment, the scientific research assistant felt that the good impression he had established about Western countries had been shattered.

It was as if she knew that the seemingly perfect goddess also needed to poop with her beautiful ass.

After being hit, the scientific research assistant looked a little depressed for a while.

He didn't continue to say anything to Zhang Xingyang.

Instead, he silently continued to sort out the files that Zhang Xingyang had screened.

In fact, what initially limited Zhang Xingyang's speed in filtering files was Li Fei's slow recording speed.

Wanting to completely keep up with his speed.

At least a computer capable of automatically browsing records is required.

In the office, it was back to the time when only the sound of paper documents being turned over could be heard.

After several hours.

Li Fei burst into the office panting.

"Director, something happened!"

Zhang Xingyang instantly stood up from the pile of documents and asked:

"What happened?"

"Construction site, or somewhere?"

At present, the construction of nuclear power plants and related research facilities has entered the most critical period.

No matter which one has a problem, no one wants to see it.

It would be okay if there were just some problems in the construction of the project.

I am afraid that a major safety accident may occur, causing a large number of casualties.

"no no."

Li Fei quickly shook his head.

Almost everything at the construction site is now under military control, and it is almost impossible to cause problems.

Zhang Xingyang breathed a sigh of relief when he heard the negative answer.

"It was people from the pipeline design team and the materials laboratory who started arguing."

After taking a few deep breaths, Li Fei suddenly revealed the problem.

This situation is not uncommon.

How can someone who is engaged in engineering design not quarrel with others? !

Zhang Xingyang just felt strange.

It was just a quarrel, so why did it come to him?

"What exactly happened? Please tell me carefully."

Zhang Xingyang just finished speaking and said again:

"Forget it, let's go to the scene and talk about it. Where are they now?"

Li Fei didn't say much nonsense and turned around to lead the way for Zhang Xingyang.

When the scientific research assistant saw this, he was ready to follow him to see the excitement.

But before he could even walk out of the office door, he was stopped by Zhang Xingyang.

"You continue to organize the information and finish all the piles before leaving get off work."

Before leaving the office, Zhang Xingyang pointed to the files on the desktop that formed a great wall.

Before the scientific research assistant could fight for themselves, the two left the office.

The scientific research assistant, who was looking at a large pile of documents with eyes blurred, was left crying without tears.

The current buildings of the institute are not very high.

The above-ground part has only 6 floors.

There are more underground parts, with each building having at least six floors and the most having eight floors.

It is said that the construction team is equivalent to digging out a mountain.

In fact, it is not that exaggerated. The deepest laboratory is only about 80 meters underground.

What Li Fei took Zhang Xingyang to at this time was the building where the equipment design team was located.

They don't use much underground experimental space on a daily basis.

Therefore, the offices are mainly concentrated on the first floor, with several relatively tall factories attached.

"What on earth were they arguing about?"

Zhang Xingyang also asked Li Fei this question on the way.

However, Li Fei thought for a while and did not answer. Instead, he said: "This matter is quite troublesome to talk about. Let them explain it themselves when we get to the scene."

The distance between the buildings is not far, and they will be there after walking for three or four minutes.

As soon as I approached the equipment design office, I heard a lot of quarrels coming from it.

"With such material requirements, why don't you go to heaven?"

"It's not like I've never been to the sky before. I was a paratrooper when I was young!"

"What's wrong with the equipment designers? Now they have to pile up materials to meet the design requirements?"

"It's obvious that you can't make materials that meet the requirements, but you're still raking them out!"

"Brothers, come on, give these material guys a little physical shock."

Listening from the outside, it seems that both sides have begun to fight.

Zhang Xingyang hurriedly opened the door and shouted: "Stop it!"

However, the actual scene inside the room was somewhat unexpected.

Dozens of experts and scholars who are well-known in their respective fields in the country are each holding a few pieces of paper and don't know what to write.

Although many people were still angry, they did not take action.

Most of the people in the room were still at a loss, holding pens and papers, looking at Zhang Xingyang who suddenly broke in.

Zhang Xingyang also felt slightly embarrassed at this time.

Fortunately, I was thick-skinned enough, so I coughed and asked:

"What are you doing now?"

Someone quickly responded, "Director Zhang, you have to give us a review."

"These guys are engaged in equipment design and bully us into making materials."

"You used to make materials, so you can definitely understand us!"

Many people present are well aware of Zhang Xingyang's historical honors.

Many of his achievements are in the field of materials science.

Similar to two-dimensional carbon fiber, composite materials, high-temperature superalloys, third-generation semiconductors, etc.

He did almost everything by himself.

This has also led many people to regard Zhang Xingyang as a beacon in materials science.

But when he said this, the bald scholar next to the man suddenly became anxious.

"Director, we are not bullying others, we also follow the actual requirements!"

"The so-called actual requirement is to increase the strength of the previous material by another 20%!"

The materials researcher next to him immediately retorted.

At this time, Zhang Xingyang reluctantly understood what they were arguing about.

It is mainly an academic debate based on their respective research contents.

It's much better than the worst-case scenario I predicted before.

"Ahem."

Zhang Xingyang did not continue to tolerate their quarrel, but directly stopped both parties.

"Next, I'll ask and you answer."

Immediately afterwards, Zhang Xingyang looked at the materials researcher who initially complained.

"You start talking first, what is going on?"

The materials researcher saw that Zhang Xingyang seemed to be standing up for them, so he said excitedly:

"Director, you also know that one of the difficulties in building a molten salt reactor is the corrosion resistance of the heat exchange pipes."

Everyone present knew this, and no one said anything.

So he continued: "According to the design standards we specified previously, under the standard flow rate of molten salt fluid in the pipeline, our corrosion resistance is already 1.6 times that of the previous reactor."

"For us, this number is something we can only achieve by gritting our teeth."

"In fact, we are only able to achieve 80 percent of the design requirements."

When the material researcher said this, he gritted his teeth and looked at the bald man next to him.

“But the equipment design team insists that as the flow rate increases, the corrosiveness of molten salt will become stronger, requiring us to continue to increase the corrosion resistance of the material by 20%!”

"This is not forcing others to do something difficult, what is it!"

After he finished speaking, the researchers in the materials laboratory present all responded.

"right!"

"Indeed it is!"

"The requirements were already very high, but now the requirements are not to embarrass us!"

Seeing that he has aroused the anger of the crowd.

The bald head hurriedly said to Zhang Xingyang:

"Director, you don't know, it's really not me who is making things difficult for them."

"This is our latest calculated corrosion rate table at the maximum flow rate. You can take a look."

"I believe that after reading this, you will be able to understand why we do this!"

As the bald man spoke, he reached out and handed several calculation books to Zhang Xingyang.

"Give me some time, let me take a look first."

Zhang Xingyang took the calculation book and said to the materials researchers on the side.

It took a minute to carefully look at the calculation book the other party gave me.

Zhang Xingyang finally figured out the source of the problem.

The reason actually lies in the reactor itself.

As we all know, before this, domestic reactors were either pressurized water reactors or boiling water reactors.

Both use water as the heat transfer medium.

The water inside the pipeline is often in a state of high temperature and high pressure.

The molten salt reactor they are building now is in a high-temperature and normal-pressure state.

But unlike a boiling water pile, the temperature of molten salt can reach 700 degrees!

As the temperature increases, the requirements for pipelines become higher.

Originally, everyone had already taken this into consideration when formulating the preliminary design indicators.

But when it comes to the pipeline design team, it’s still time to do the actual work.

Still found the problem.

There is a big difference between theory and practice.

Simply put, the strength of the pipe material originally designed did not meet the requirements.

That's why they asked the materials research and development department to develop materials with a 20% increase in intensity.

Zhang Xingyang did a little mental calculation.

I found that this number was not brought up casually.

It is just the minimum strength that can maintain the pipeline without being damaged under the impact of high-flow molten salt.

Even if the strength is lower, the pipe can still withstand it.

But the service life will be greatly reduced.

Nuclear reactors generally have a long service life.

At least forty years!

"I already understand the cause and effect of the problem."

Zhang Xingyang put down the calculation book in his hand, looked at both sides and said.

"The problem this time is not your fault, it is mainly our problem."

"When doing theoretical calculations, we still consider ideal conditions."

"The actual situation is even less ideal than we thought."

Zhang Xingyang first apologized to the pipeline designer.

If this matter is traced back to its origin, it is actually the problem of the people who set the design indicators.

Most of the indicators for the nuclear power plant were set by Zhang Xingyang and the team leaders.

Zhang Xingyang's apology obviously made most people feel a little embarrassed.

Their ideas are also very simple and honest.

The main reason is the indignation after seeing the outrageous design specifications.

As for the others, not really.

"Now you know, it's really not us who is trying to punish you."

The bald man seemed to be proud and proud at this time.

"It is indeed our pipelines that require materials of this strength."

The materials researcher next to him was also a little discouraged at this time.

I didn't expect that it would be like this in the end.

"But the strength requirements of this material are too high. No one in the world can develop it, let alone us."

As soon as these words came out, many people present became depressed.

Zhang Xingyang laughed at this time and said:

“What others can’t do, doesn’t mean I can’t do it too.”

"Since there is no material of this strength in the world now, we will develop it ourselves!"

Zhang Xingyang exudes strong confidence.

If you put it on others, it can be regarded as conceited!

However, no one present doubted that Zhang Xingyang could do it.

After all, that's the kind of man he is.

Never let anyone down!

Others present were also infected by Zhang Xingyang's strong confidence.

They all expressed their willingness to join Zhang Xingyang's team that develops new materials. (End of chapter)
