Chapter 223 223 New methods of producing radioactive substances

"You mean... smaller?"

"Yeah, although this thing looks very convenient, how can I put it? It is more than enough than the above. Compared with nuclear power devices, its battery life and power are not enough, but compared with conventional batteries, Much stronger."

"Hurry up, Xiao Wang, don't listen to his nonsense, he may be so happy in his heart, and he is still picking and choosing here..." Elder Ren said unwillingly.

Wanting to make the device smaller is not a theoretical problem, but an engineering problem. Before the emergence of more excellent superconducting materials, this thing was impossible without even thinking about it.

"I'm talking with Professor Wang here, what are you talking about?"

"Just because you can't do it doesn't mean others can't do it, right, Professor Wang!"

As a person who has dealt with ships and electricity all his life, he really knows what the appearance of this thing means, but how to say, it would be great if it could be made smaller, even if the power is small Anything at all is perfectly acceptable.

"Ahem, I'm only responsible for solving theoretical problems. For specific engineering problems, I still have to listen to the opinions of the elders. After all, I only have a bachelor's degree in electrical engineering..." Wang Feng said helplessly.

"That's a pity. With this guy, there is probably no hope..."

"It sounds like you are so powerful. If I can't do it, can you do it?" Mr. Ren said angrily.

"That's not necessarily the case. Our experience in nuclear engineering is not necessarily less than yours, especially with the miniaturization of devices."

"That's good, tell me how to reduce the size of the superconducting magnet while maintaining the magnetic field strength?"

"Tell me, how to reduce the cooling device to ensure that the magnet does not overheat and exit the superconducting state?"

……

"No, wait a minute, are you still studying these things?"

"Do you think nuclear devices only have nuclear fission, and nuclear fusion!"

Mr. Ren spread his hands: "It's a pity that nuclear fusion is still 50 years away, so I'm afraid you won't see it in your life... But I'm fine, they designed and customized a lot of equipment from us, including this Superconducting magnets and cooling…”

Be silly, we still study fusion!

Moreover, electromagnetic decay accelerators do not rely on fission technology, but fusion technology, especially superconducting magnet technology, which is one of the core technologies of nuclear fusion.

A very important way of superconducting technology is to use superconducting materials to make superconducting magnets with extremely strong magnetic properties.A superconducting magnet is actually a closed superconducting coil wound with a superconducting wire or strip.When the current is applied to the superconducting coil, a strong stable magnetic field can be maintained.Compared with ordinary magnets, superconducting magnets have many advantages such as small size, high stability, and low energy consumption.

In the study of nuclear fusion energy, superconducting magnets are the key core of the tokamak device.Advances in particle accelerators also depend to some extent on the level of superconducting magnets.From the BJ Electron Positron Collider to the European Large Hadron Accelerator, the accelerating magnets and detectors all use superconducting magnets.The superconducting magnets of particle accelerators can enhance the deflection and clustering capabilities of particles, thereby greatly shortening the length of the accelerator channel.

Superconducting generators made by applying superconducting magnets to generators can increase the power generation capacity of a single unit by 5 to 10 times compared with conventional generators, while the weight and volume of the whole machine are reduced by 1/3 and 1/2 respectively. The power generation efficiency is increased by about 50%.Military ships and aircraft use superconducting generators, which can increase their combat effectiveness.

The superconducting maglev train is another typical case of the application of superconducting magnets.Compared with conventional maglev technology, superconducting maglev trains will be faster, more stable and safer.Because superconducting magnets can pass a large amount of electric current, they generate a larger magnetic field than conventional magnets.At the same time, since the superconducting magnet has almost no resistance, it only needs to maintain its low-temperature working environment to ensure that it does not quench when the power is removed after the current is applied once.In this way, superconducting magnets have the advantages of light weight, small size, low energy consumption and high efficiency.

Of course, the use of superconducting materials is far more than that. In today's society, the importance of electricity is beyond doubt.

However, the power loss of long-distance transmission is surprisingly large.The data shows that my country's transmission and distribution losses account for about 6.6% of the country's power generation, most of which are resistance losses of transmission and distribution lines.The development of superconducting power transmission technology is undoubtedly a potential way to solve the loss dilemma of large-capacity power transmission and distribution.

Superconducting power transmission technology is a new power transmission technology developed using superconducting materials with high density current carrying capacity. Superconducting transmission cables are mainly composed of superconducting materials, insulating materials and low-temperature containers that maintain the superconducting state.The current carrying capacity of superconducting materials can reach 100 to 1000 A/mm50, which is about 500 to 25 times that of ordinary copper or aluminum and other materials.The power transmission loss of superconducting cables is almost zero. There is a certain AC loss during AC power transmission. The total power transmission loss can be reduced to 50% to [-]% of conventional cables.

At present, the research on superconducting cable power transmission technology has made important progress.The transmission capacity of superconducting transmission far exceeds that of traditional overhead transmission lines and oil-filled cable transmission lines, and is also greater than that of inflatable transmission pipelines and low-temperature low-resistance cable transmission.Scientists estimate that if superconducting power technology is used in power generation, power transmission, and power distribution, the total efficiency of power resources will increase by about 5%.

At present, my country's electricity mainly comes from coal-fired power generation.Superconducting cable transmission can not only reduce the loss of the power grid, but also reduce the emission of pollutants, so its application prospect is very promising.At the same time, the use of superconducting power transmission can also simplify the thermal insulation of generators, transformers and motors, and ensure the stability and safety of power transmission.

So in this area, everyone is scrambling to move forward. Since the 20s, high-temperature superconducting materials have come out one after another, and the critical temperature of superconducting has also continued to increase.The research of Chinese scientists in the field of iron-based high-temperature superconductivity has been at the forefront of the world's superconducting technology research. In particular, China's successful development of the world's first 80-meter-level iron-based superconducting long wire has accelerated the introduction of superconductivity into practice. the pace of life.

Of course, it is not easy to use this thing. At present, people still use copper oxide more. While using copper oxide materials, we should study the formation mechanism of superconductivity contained in it.

The current mainstream view is that the superconducting pairing of cuprate high-temperature superconductors does not originate from the traditional BCS electroacoustic coupling, but from the strong correlation effect between electrons.In order to deal with the strong correlation effect in this kind of system, people have put forward a variety of treatment methods in theory.This article reviews one of the more commonly used theoretical treatments, the renormalized mean-field (RMFT) method.

It is used in Wang Feng's device. This is part of the scientific research task they undertake in the international controllable nuclear fusion project, but it is only a simplified version. The ultimate version is not a small toy the size of an MRI machine. , but a big guy as tall as several floors!
The China National Nuclear Corporation has reserves for this technology, but if you are a shipbuilder, it must be impossible to have it, right?

Ren has long seen what this guy wants to do, but he just doesn't mention it. It's a rare opportunity to see this old boy deflated.

Although scientists are polite when they treat outsiders, it is for the outside to see. Inside, especially when they are discussing issues... the scene is quite spectacular.

At this time, this guy is the most confident, why?

Because the sea-based nuclear force is the most important part of the trinity strategy and the final guarantee to ensure mutual destruction, so... finally caught this kid today!

"Hey, although we can't help with superconductivity, our electrical design and manufacturing capabilities are top-notch, and we can definitely help a lot. How about it!"

"Do you want to join the ship too?"

"Look at what you said, it's all about making contributions to the country, how it sounds like..."

"That's not necessary, after all, our cooperation is quite pleasant, and our capabilities are completely sufficient..." Although Mr. Ren knew that the joining of CSSC was a foregone conclusion, he didn't plan to do anything on it, but He still wanted to see the other party give in.

After all, at their age, isn't it just a fight?
Academician Zhang: "..."

"Okay, I also brought a bottle of fine wine, haven't you been thinking about it for a long time, I brought this today!"

"That's good, you go and type up the report first, and then we'll have a few drinks in the evening, and today we've got the honor of Professor Wang!" It's almost done here, Mr. Ren is very satisfied, and can let this kid He bowed his head and obediently took out the treasured wine, and he was considered a victory.

"Now we have found a good place for those fission products... But in the future, will there be enough fission products?" Two old academicians and Wang Feng chatted as they walked.

"It will definitely die. In the future, it will not be a matter of a few kilograms or tens of kilograms. It is estimated that hundreds of kilograms or even tons will be used. Nuclear power plants alone will definitely not be enough." Wang Feng replied without thinking.

"What should I do?"

"At that time, we will have to find a way to artificially produce radioactive materials, of course not relying on nuclear reactions to produce them, but relying on strong magnetic fields, the kind of strong magnetic fields as high as tens of t, through the weak electric correlation model. Produce radioactive elements!"

"Wait a minute, young man, your idea is a bit dangerous!"

"If radioactive nuclides can be produced just by relying on this, do you know how harmful this technology will be?"

"This technology still needs to be cautious!"

Wang Feng:? ? ?
"No, do you have any misunderstanding about the strong magnetic field?"

"The magnetic field of dozens of tons is not something that ordinary people can play with?"

"No, there are not many laboratories with this thing at all, let alone use it well; you must know that we have built a supercomputer specially for this thing, these things add up, and there are no billions that can't be used at all. Turn, and even if you have money, there is no place to buy these things!"

"Not to mention the troublesome power consumption and electricity bills at that time, isn't this goal obvious?"

Wang Feng talked for a long time without noticing the smiles in the eyes of the two old men: "Don't be nervous, just kidding and relax, if the teacher is so serious, it's easy to get mentally fatigued!"

Wang Feng:! ? ?
Are you guys born in the 60s joking around like this?

"No... I wasn't nervous at first, but after you said that, I suddenly felt that this technology is quite dangerous. Otherwise, forget it. I'd better go back and study my chemistry. I have money and money. Honor!"

"No, wait, don't take it seriously. As you said, with so many restrictions, other people simply don't have this ability. What are you worried about?" They were joking at first, but when they saw Wang Feng That serious look made them a little flustered:
The kid doesn't really intend to go back to chemistry, does he?
"I still don't want it, it's too dangerous, and it's not very ambitious, it's easy to attract criticism."

"No, even those outsiders are full, but everyone still remembers you, and the country also remembers you. Taking your current results as an example, at least it is a national award!"

"Oh, I already have it!"

Two people: ...

"By the way, I heard that they plan to award me the Nobel Prize in Chemistry. I think it's better not to be idle."

Two people: Σ(⊙▽⊙”a
Although it may not be very good to say so, the National Award does not seem to be as compelling as the Nobel Prize, especially if it is an award in the natural sciences!

It is no exaggeration to say that the Nobel Prize is basically the highest honor that a scientist can get. No scientist would not like to get her, but she is like a world-class goddess who only favors the limited number of people in the world every year. Then a lucky couple or two...

If the Nobel Prize Review Committee really intends to award this year's Nobel Prize in Chemistry to the young man in front of them, then they really have to consider this realistic question: whether they really want the other party to continue to engage in this kind of work? Sensitive research!
"Hey, don't you guys really take it seriously? I'm just kidding!" Wang Feng was a little panicked when he saw that the two bosses were really thinking seriously: Without the help of these two bosses, he wouldn't have that industrial ability!

"Are you talking about the Nobel Prize or the project?" Mr. Ren asked seriously.

"Of course it's a project. According to my friends and mentors abroad, I have a high probability of winning the chemistry award this year. If there is no discovery that can compare with my achievements, then this year's award will be mine. .”

"Then I understand!" Elder Ren said: "All the results of this period of time are temporarily sealed, don't leak any information, I will go to the higher-ups to ask first."

"However, as far as I am concerned, it is better to suspend our project for a period of time, which is beneficial to you."

If a Nobel Prize winner can be cultivated locally, it will be very beneficial to the country. Anyway, this project is not in a hurry. At present, high-energy batteries are enough for them to digest for a while.
