"Director, is this paper useless?"

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

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

The office, which still smelled of paint, has long been replaced by the smell of old papers.

It has a strong musty smell.

Even if the air purification system in the room is working non-stop, it can be difficult to get rid of the odor in the office.

"I'll see."

Zhang Xingyang took a document from his assistant's hand, glanced at it a little, and said:

"There's something wrong with the paper, it's just that they haven't been taken down."

"Actually, it's not as strong as the data they say in their paper."

"We experimented with it three years ago."

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

Although the research assistant is also a Ph.D. from a top university in China, he has only read this article before.

No experimental reproductions have been conducted.

In fact, even if they want to reproduce, they don't have that condition.

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

Zhang Xingyang recalls the scene at that time, "At that time, we also wrote a letter to the journal, giving the mistakes in the article. ”

"But I didn't expect that they haven't taken it down yet."

"I don't know if it's because it's too inefficient, or if it's something else."

The research assistant asked curiously, "Don't they all say that Westerners are efficient?" ”

THE ERA OF MOBILE INTERNET HAS JUST BEGUN, AND ENTERTAINMENT SOFTWARE SUCH AS TIKTOK HAS NOT YET DEVELOPED.

Chinese people always have a filter that is difficult for others to understand about countries they have never seen.

Only after the rise of short video platforms has an all-round insight into all aspects of other countries in the world.

will understand that many good impressions in this world are just your own YY.

Zhang Xingyang said: "There is also a difference in the efficiency of work in the West, this is a John Bull journal, they only publish two issues a year. ”

"With their efficiency, it is possible to see the letter within two years and retract it within four or five years."

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

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

It's as if she knows that the goddess who seems to be perfect also needs to shit with a beautiful ass.

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

did not continue to say anything to Zhang Xingyang.

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

In fact, at the beginning, the main thing that limited Zhang Xingyang's speed of screening documents was that Li Fei's recording speed was too slow.

Wanting to keep up with him completely.

At a minimum, you'll also need a computer that can automatically browse through your records.

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

A few hours later.

Li Fei burst into the office out of breath.

"Director, something happened!"

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

"What's wrong?"

"Construction site, or where?"

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

No matter which one goes wrong, everyone doesn't want to see it.

If it was just a little problem in the construction of the project, it would be good to say.

I am afraid that there will be a major safety accident, resulting in a large number of casualties.

"No, no."

Li Fei hurriedly shook his head and said.

The construction site is now almost entirely under military control, and it is almost impossible to have problems.

Zhang Xingyang was slightly relieved when he heard the negative answer.

"It's the piping design team and the materials lab who are arguing."

After taking a few breaths, Li Fei suddenly said what the problem was.

This is not uncommon.

How can you not quarrel with people if you are engaged in engineering design?!

Zhang Xingyang just felt strange.

It's just a quarrel, how can it come to him.

"What the hell is going on, let's talk about it carefully."

As soon as Zhang Xingyang finished speaking, he said:

"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 directly to lead the way for Zhang Xingyang.

Seeing this, the scientific research assistant was also ready to follow and see the excitement.

It's just that before he walked out of the office door, he was stopped back by Zhang Xingyang.

"You continue to organize the materials and finish the bunch before you get off work."

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

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

Only the scientific research assistant who looked at a large pile of documents and his eyes were clouded wanted to cry without tears.

The current buildings of the institute are not very tall.

The above-ground part has only 6 floors.

The underground section is a bit more subterranean, with a minimum of 6 floors and a maximum of 8 floors per building.

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

In fact, it is not so exaggerated, and the deepest laboratory is only about eighty meters underground.

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

They don't use much underground space for experimentation on a day-to-day basis.

Therefore, the office is mainly concentrated on the first floor, with several tall factories.

"What the hell are they arguing about?"

On the way, Zhang Xingyang also asked Li Fei this question.

However, Li Fei thought about it and didn't answer, but said: "It's quite troublesome to talk about this matter, let them explain it themselves when they get to the scene." ”

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

As soon as I got close to the equipment design office, I heard a lot of noise coming from it.

"Why don't you go to heaven with such material requirements?"

"It's not that Lao Tzu hasn't been to heaven, Lao Tzu was a paratrooper when he was young!"

"What's wrong with the equipment designers, now, they have to rely on stacking materials to meet the design requirements?"

"Obviously, you can't make materials that meet the requirements, and you still have a rake!"

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

From the outside, it seems that both sides have begun to make a move.

Zhang Xingyang hurriedly pushed open the door and shouted, "Stop it!" ”

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

Dozens of experts and scholars, who are well-known in their respective fields in China, are each holding a few pieces of paper, not knowing what to write.

Although many people still have depression between their eyebrows, they didn't do anything.

Most of the people in the room were still at a loss for what to do, holding paper and pen, looking at Zhang Xingyang who suddenly broke in.

Zhang Xingyang also felt slightly embarrassed at this time.

But fortunately, his face was thick enough, and he coughed and asked:

"What are you doing now?"

Someone quickly reacted, "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 must be able to understand us!"

Zhang Xingyang's historical honors are very clear to many people present.

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

Similar to two-dimensional carbon fibers, composite materials, superalloys, third-generation semiconductors, and more.

He did almost all of it single-handedly.

This also makes many people regard Zhang Xingyang as a lighthouse in materials science.

But as soon as he said this, the bald scholar beside the man suddenly became anxious.

"Director, it's not that we bully people, we also come according to the actual requirements!"

"The so-called practical requirement is to increase the strength of the previous material by 20 percent!"

The material researcher next to him immediately retorted.

Zhang Xingyang also barely understood why they were arguing at this time.

It is mainly an academic debate because of the content of their respective research.

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

"Ahem."

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

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

Immediately after, Zhang Xingyang looked at the material researcher who had complained at the beginning.

"Let's start with it, what the hell is going on?"

Seeing that Zhang Xingyang seemed to be trying to stand up for them, the material researcher said with some excitement:

"Director, you also know that one of the major difficulties in making molten salt reactors is the corrosion resistance of heat exchange pipes."

This was well known to everyone present, and no one said anything.

He continued: "According to the design criteria we specified, the molten salt fluid is already 1.6 times more corrosion resistant than the previous reactor at the standard flow rate in the pipeline." ”

"That's a number for us to grit our teeth and be able to do it."

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

The materials researcher said this, gritting his teeth and looking at the bald head beside him.

"But the equipment design team has to say that when the flow rate increases, the corrosion of molten salt will increase, and we are required to continue to increase the corrosion resistance of the material by 20%!"

"It's not a strong man's difficulty, what's it!"

When he finished speaking, the researchers who belonged to the materials laboratory responded one after another.

"Yes!"

"That's true!"

"It was originally very demanding, but now such a request is not to embarrass us for anything!"

Seeing that he has caused outrage.

The bald head hurriedly said to Zhang Xingyang:

"Director, you don't know, it's really not me who embarrass them."

"Here's our latest calculation of the maximum flow rate, the corrosion velocity gauge, you can take a look."

"I'm sure you'll be able to see why we're doing this!"

The bald head said as he reached out and handed a few calculation books to Zhang Xingyang.

"Give me some time, I'll take a look first."

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

It took a minute to take a closer look at the calculation book that the other party had given him.

Zhang Xingyang finally figured out the root of the problem.

The reason is actually the reactor itself.

It is known that before this time domestic reactors were either pressurized water reactors or boiling water reactors.

Both use water as the heat transfer medium.

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

And the molten salt pile they are going to do now is in a state of high temperature and atmospheric pressure.

However, unlike boiling water reactors, molten salt can reach a temperature of 700 degrees!

As the temperature increases, the requirements for the pipes will be higher.

Originally, when we were doing the preliminary design index formulation, we had already taken this into account.

But when the piping design team is still actually working.

I still found a problem here.

There is a big difference between theory and practice.

To put it simply, the original design of the pipe material strength did not meet the requirements.

That's why they asked the material R&D department to increase the strength of materials by 20%.

Zhang Xingyang did a little mental calculation.

It was found that this figure was not something they came up with casually.

It is just the minimum strength that can maintain the pipeline under the impact of molten salt at high flow rate without damage.

The strength is lower, although the pipe can withstand it.

But the service life will be greatly reduced.

Nuclear reactors, on the other hand, 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.

"I don't blame you for this problem, it's mainly our problem."

"When calculating theoretically, we still think about the ideal situation."

"It's even worse than we thought."

Zhang Xingyang first apologized to the pipeline designers.

If this matter is traced back to the source, it is actually a problem of the person who formulated the design indicators.

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

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

Their ideas are also very simple and simple.

The main thing is the indignation after seeing the outrageous design indicators.

As for the rest, not at all.

"Now you know, it's really not us who is going to fix you."

The bald head seemed to raise his eyebrows at this time and said.

"It's really our pipes that need materials of this strength."

The material researcher beside him was also a little deflated at this time.

I didn't expect it to be the end of it, but it was really like this.

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

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

Zhang Xingyang laughed at this time and said:

"Just because others can't do it doesn't mean I can't do it either."

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

Zhang Xingyang exudes a strong sense of 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, he is such a man.

Never let anyone down!

The others present were also infected by Zhang Xingyang's strong self-confidence.

They have expressed their willingness to join Zhang Xingyang's team in the research and development of new materials. (End of chapter)
