Chapter 317: Four Generation Reactors!
"Professor Zhang, this is our latest generation of nuclear reactors."
Experts in dark blue, nameplate-free uniforms enthusiastically introduce their latest masterpieces.
Around the pale white reactor, there was not a single trace of dust to be seen.
"Two VK-2M PWRs, capable of providing more than 280 megawatts of electricity."
"I wonder if I can meet your needs?"
Nuclear power experts don't know the identity of the person in front of them.
But the fact that I don't know my identity is enough to get a glimpse of the leopard.
Those who can become experts in nuclear power construction are absolutely too familiar with secrecy to be more proficient.
Even they don't know that the true identity of the person who came is definitely the highest level of secrecy.
"The electricity supply is barely enough to meet the demand."
Zhang Xingyang, who was wearing a white hard hat, nodded slightly:
"But what about security?"
"Our application scenario is very special, and we can't afford to make the slightest mistake."
"Once a failure occurs, it will not only cause hundreds of billions of economic losses to the country, but also hundreds of casualties."
Although Zhang Xingyang did not specify the application scenario, nuclear power experts still heard the seriousness of it.
In the blink of an eye, nuclear power experts have thought of possible application scenarios.
Nuclear submarine!
Although he did not know the cost of a nuclear submarine, it was definitely an astronomical amount.
As for the number of casualties, it is better to understand, if the reactor fails, then the officers and men of the Navy on a whole nuclear submarine will basically not survive.
After the nuclear power expert figured out this layer, he was instantly a little awe-inspired:
"Our reactor failure rate is definitely the lowest."
"I'll vouch for my life, and there won't be any problems with them."
The origin of domestic nuclear power is actually the application of nuclear reactors on nuclear submarines.
At that time, in the face of the nuclear deterrence of the world's two superpowers, the great man proposed: "Nuclear submarines must be built in 10,000 years!" ”
It took only five years from the official launch of the project in 65 years to the launch of the first nuclear submarine in 70 years.
The most difficult of these is the nuclear reactor at the heart of the nuclear submarine.
Zhang Xingyang believes that when the other party says this, he is absolutely sincere.
However, the requirements for reactor inspections have not been relaxed.
"This reactor, we'll take it away when we're done."
"But we won't be the slightest bit lax in the inspection requirements."
Zhang Xingyang still maintained a serious expression and said.
"That's as it should be." The nuclear power expert nodded.
"Do you want us to help with the inspection?"
Out of kindness, the nuclear power expert asked more.
Zhang Xingyang waved his hand: "No need, we have our experts." ”
Then he brought the members of the expert group and politely stepped forward to start handing over the reactor construction personnel.
A comprehensive inspection of the reactor was then carried out, and every screw was thoroughly tested to ensure their strength.
"How long have you been working at a nuclear industry company?" In his spare time, Zhang Xingyang chatted with the nuclear power experts around him.
The nuclear power expert obviously didn't think about this problem, and was stunned for a moment before saying, "It's been about 20 years." ”
"When I first graduated, I joined the Ministry of Nuclear Industry, and then the department was reorganized, and I joined the Nuclear Industry Company."
seemed to remember his past years, and said with some emotion:
"At that time, we had just started to build civil nuclear power, and we didn't have much experience."
"It was Peng Lao who led us to learn from the nuclear power construction of the Gauls, otherwise there would not be many civilian nuclear power plants now."
Zhang Xingyang remembered a name, but didn't say it.
Because of his many information, it should not have been declassified at this time.
Speaking out yourself, it is likely to cause unnecessary trouble.
Peng Shilu, one of the first nuclear power experts in China, once presided over the construction of the first nuclear submarine in China, and promoted the establishment of many systems in nuclear power construction.
"Do you have plans for a four-generation reactor now?"
Zhang Xingyang changed the topic and asked.
"The current size and power of the reactor are still far from our ultimate goal."
Before the reception, the nuclear power specialist was authorized.
You can tell them all about this.
"To be honest, the international understanding of the third-generation reactor is still in a state of development and perfection, and the fourth-generation reactor is only a theoretical thing."
The claims of nuclear power experts are a bit of a rhetoric.
But I still understand it.
That is, theoretical research was done, but the actual development progress was zero.
"We have a lot of ambitions for miniaturized reactors, and if you're interested, I think we can work together."
Zhang Xingyang smiled and extended an invitation to the other party.
"Of course, we have a great research interest in the fourth-generation reactor!"
The nuclear power expert said excitedly.
In fact, he can't do this kind of thing.
Especially if you are completely unaware of the opposing unit.
However, nuclear power experts thought they had guessed the other party's origins.
has already made up a reason for Zhang Xingyang's brain.
If nuclear submarines are to be further developed on a larger scale in the future, then the current reactors may not be able to carry them.
Doesn't this require a stronger heart, that is, four generations of piles!
In addition to nuclear submarines, nuclear-powered aircraft carriers may also need fourth-generation nuclear reactors.
The reactor of a nuclear submarine can also be used in a nuclear-powered aircraft carrier to some extent.
For example, the aircraft carrier Charles de Gaulle in Gaul uses the GEC Alsthom PWR Type K-15 nuclear reactor on the Gallic Triumph-class nuclear submarine.
However, it also caused another problem.
The Gallic aircraft carrier became the floor tile of the aircraft carrier's speed after the war.
The actual maximum speed was only 25 knots.
And the general aircraft carrier speed is more than 30 knots.
"In fact, we have already conducted a lot of theoretical research on the fourth generation reactor."
Nuclear power experts came to talk and talk.
"Our theoretical research is mainly focused on the field of thermal neutron reactors."
"There has been an experimental UHT reactor in the world before, which has been successfully built in South Africa.
However, the cost of its supercritical steam boiler is so high that we are not prepared to build such a reactor. ”
After talking about ultra-high temperature reactors, nuclear power experts reacted slightly.
Isn't what I said a little professional, and I'm a little afraid that the other party won't understand.
Zhang Xingyang saw the other party stop, and raised his eyebrows: "So you haven't conducted research on molten salt reactors?" ”
Before Zhang Xingyang, the thorium-based molten salt reactor mentioned by Geng Bo belongs to this category.
Nuclear power experts are a little surprised, now that the international exploration of fourth-generation reactors has just begun, not many people know about molten salt reactors.
"We've looked at that as well."
"You've done a lot of theoretical research." Zhang Xingyang said.
The nuclear power expert smiled slightly, "In the past days, the scientific research funding was not very sufficient, and we were able to conduct some theoretical research. ”
"Experimental piles are very expensive."
Zhang Xingyang nodded in agreement, he also always felt that the scientific research funds were not enough to spend.
The cost of building an experimental reactor is estimated to cost a whole year's profits of the nuclear industry company.
"We have also done some model calculations that nuclear fuel is dissolved in fluoride to form metal salts."
The nuclear power expert, who just cried poor and wanted to wait for a little more money, said:
"For example, uranium tetrafluoride and thorium tetrafluoride, according to our calculations, reach a critical mass when the molten salt fluid of the mixed nuclear fuel flows into the graphite-decelerated core."
"It's a very feasible design option."
Zhang Xingyang was just about to say something, when there was a gradual uproar within the team of experts inspecting the nuclear reactor.
He paused what he was about to say.
Nuclear power experts have also turned their attention to the team of experts in dispute.
The two glanced at each other and walked together towards the experts who were arguing.
"What's going on?"
Zhang Xingyang stretched out his hands, pulled the two people apart, and asked the person next to him.
"Lao Qin and Lao Yao have a little different opinions on the strength requirements of a structural part, and then neither of them is convinced."
On the one hand, the person who had been watching the beginning and end of the incident was enthusiastic to explain to Zhang Xingyang.
After listening, Zhang Xingyang was a little helpless.
This kind of thing, it's really hard to judge who is right and who is wrong.
However, Zhang Xingyang was still very curious and asked: "What kind of structural parts make the two of you so disagreeing?" ”
"The main axle of a closed-cycle gas turbine."
Lao Qin tidied up his clothes and said calmly.
"As the core of the power generation equipment, I think it is necessary for it to achieve the theoretical optimal strength."
Lao Yao, who was obviously a little unconvinced on the side, was obviously angry when he heard this, and even wanted to rush forward and pull Lao Qin's collar.
"You're embarrassed to say the theoretical maximum, is that achievable in reality?!"
Obviously, Lao Yao is from a related manufacturing industry and has a clear understanding of how big the gap between theory and practice is.
Lao Qin is an obvious theoretician, pursuing the so-called theoretical optimum.
Industrial manufacturing is not just writing and drawing on paper, and theoretical values can really only stay on paper.
Generally speaking, as long as it is within a certain margin of error, everyone can accept it.
"What is the difference between the measured value and the theoretical value?"
The two are fighting so hard, Zhang Xingyang also preconceived that the gap between the two may be relatively large.
"Actually, the gap is much smaller than we thought before."
Still the zealous onlooker:
"The measured value is only 2/10,000 smaller than the theoretical value."
After Zhang Xingyang listened, he was a little speechless for a moment.
The gap of 2/10,000 is actually very small.
It is within the permissible range.
A closed-cycle gas turbine serves as the generating end of the entire nuclear reactor.
The body size is very large, the main shaft alone is several meters long, nearly half a meter thick.
Not to mention a two-thousandth error, even if it is two thousandths.
Actually, it's all acceptable.
"Lao Qin, this kind of strength is enough for us."
Zhang Xingyang rarely persuaded a person.
"Professor Zhang, before coming, you asked us to be meticulous and strive for perfection during the inspection." Lao Qin said with some dissatisfaction.
Zhang Xingyang did say such things before he came.
"You can't be regarded as striving for perfection anymore, theory is theory, reality is reality, and this error is reasonable."
Zhang Xingyang said bitterly.
"We can't demand it with such standards, it will cause us a lot of trouble."
"Regardless of whether we can build a new main axle that fits the bill perfectly."
"Even if we could build it, how much time would it waste?"
"Do you know how big the impact this will be on our project?"
After listening to Zhang Xingyang's questions, Lao Qin's body, which had been tense, suddenly became deflated, and he leaned slightly:
"Professor Zhang, I know that a perfect part is impossible, but I just want to."
As he spoke, tears faintly appeared in Lao Qin's eyes:
"I just want us to use the best parts!"
"Otherwise, if there are any problems in the future, I won't be able to get over that hurdle in my heart!"
After Lao Qin finished speaking, everyone present was stunned.
Lao Qin really treats the whole project as if he were his own child.
I hope it can get the best and the most perfect in everything.
Zhang Xingyang looked at Lao Qin with a somewhat complicated look, and didn't say anything, just patted his back lightly to calm his emotions.
Although I have seen many such lovely people in this era.
But every time he meets them, Zhang Xingyang is still shocked.
They may not have the ability to do research very well.
But they have dedicated their lives to the development of the country's science and technology.
There are actually a lot of these people around Zhang Xingyang.
But Lao Qin's tears still touched Zhang Xingyang's heart.
He even changed his decision a little.
"Lao Qin, our reactor is only for verification, and there will be some extreme situations, so you don't have to worry so much."
"And, I promise you, within five years, you'll see our project a success!"
Zhang Xingyang was still immersed in the emotion of being moved, and he couldn't extricate himself.
Lao Qin had already wiped away his tears, looked at Zhang Xingyang with a smile on his face and said:
"Really!"
"A man can't go back when he speaks!"
Looking at Lao Qin in front of him, who seemed to have changed his face in Sichuan opera, Zhang Xingyang naturally reacted.
I was tricked.
Lao Qin's mood is real, but after the first persuasion, he actually figured it out.
It's just that he had a flash of inspiration and came up with a great idea.
So he got a promise from Zhang Xingyang.
"It always feels like you're playing me."
Zhang Xingyang complained slightly, but soon said seriously:
"Five years."
"Within five years, everyone will be able to see the project succeed!"
As for what the project is, no one has said clearly.
So much so that nuclear power experts have made up a whole drama on the sidelines.
An old scientist who has dedicated his life to the cause of nuclear submarines wants to see a new generation of nuclear submarines come out within his career.
The leader of the new generation has made a military order, and he must be allowed to see success within five years.
"I hope you can really succeed in your business."
The nuclear power expert said next to the crowd.
Then I saw everyone's strange eyes.
"Is there anything wrong with what I said?" Nuclear power experts muttered to themselves.
Although Zhang Xingyang didn't know what the other party had made up in his brain, he always felt weird, but he still thanked him gently. (End of chapter)
