Chapter 440: Nuclear fusion demonstration meeting, when did we have such high-end technology?
"Flower growers need to research controllable nuclear fusion technology..."
"It's impossible to succeed even in fifty years!"
When the news spread abroad, it also attracted a large number of media reports, almost all of which were unfavorable. "Such a large-scale engineering project, even if it is officially approved for research, will most likely fail midway. No matter how much manpower is invested,
Material resources are meaningless."
"Modern research into nuclear fusion is simply impractical."
"Even Amerikan and Europe, which have more advanced technology, will not be able to start research on nuclear fusion for the time being..."
"It's probably just a slogan, and it's impossible to actually invest in research."
"..."
The international media not only made judgments, but also conducted a series of analyses. The Large Example Collider project was used for comparison.
In the past many years, China has been demonstrating large particle collider projects.
The purpose of this project is to replace the aging electron-positron collider and provide the country with the most advanced collider to conduct research in related fields.
The large particle collider project has the equipment, technology, and theory, and there will definitely be no problem in manufacturing it. The only thing that needs to be demonstrated is whether it is worth the investment.
Even such a project has not been officially launched yet.
Controllable nuclear fusion is a century-old project and is considered the main energy technology in the future, but the threshold for research is too high.
For example, Germany has demonstrated that it can manufacture a complete tokamak device, but its budget exceeds 100 billion US dollars.
After spending hundreds of billions of dollars, it does not mean that the research can be completed, but that the nuclear fusion reaction can be carried out inside the device. The results are still limited to the laboratory, rather than being put into the application field.
Naturally, this kind of project cannot be approved.
The reason why the research on controllable nuclear fusion is not optimistic is that there are too many technical difficulties to be solved.
The "Times" of Eagle Country summarized several technical problems that are difficult to overcome in response to hot public opinion issues. The first is the difficulty in ignition.
Every ignition of nuclear fusion requires the creation of a high-temperature and high-pressure environment.
It is too difficult to create a high-pressure environment. Generally, it is replaced by a high-temperature environment, which requires creating an environment of at least 100 million degrees Celsius.
The second point is that computer simulations are not accurate.
This is a math problem.
All research on controllable nuclear fusion cannot avoid plasma, and problems related to plasma, including instability, turbulence, and the basic equations that control various elusive behaviors of plasma, can only be approximated through simulation calculations.
In fact, it is just like Newton's law that governs the motion of three bodies, the NS equation that governs the motion of fluids, and the Boltzmann equation that governs the motion of a large number of molecules.
It is very difficult to solve these partial differential equations, and most of them can only find approximate solutions.
There is also the matter of materials.
The reason why nuclear fusion can be called unlimited energy is because the deuterium in seawater is almost "infinite" to humans.
But the problem is, it's too difficult to use just 'deuterium'.
At a temperature of one hundred million degrees, the reaction cross section of deuterium-deuterium is nearly two orders of magnitude lower than that of deuterium-tritium. When the temperature rises to one billion degrees, the bremsstrahlung radiation will be greatly enhanced. If you want to achieve output
Larger than the input it becomes extremely difficult.
If 'tritium' is used, the problem is also obvious.
Tritium is radioactive and almost does not exist naturally in nature. Human production capacity is extremely limited, and the resources of lithium used for tritium multiplication are also limited.
Of course, the biggest difficulty is indispensable, "How to make the output greater than the input?"
From an input perspective, the power of radio frequency waves, neutral beams, and lasers used to heat plasma is smaller or even much smaller than the electrical power consumed to generate them.
From an output perspective, the efficiency of converting neutron energy into usable thermal energy is limited, and the efficiency of thermal power generation itself is not high.
etc.
There are many difficulties that need to be overcome in the research of nuclear fusion.
When the news came out, almost no one at home or abroad was optimistic that the nuclear fusion project could actually be launched.
Such research cannot even pass the argument.
But in fact, domestic nuclear fusion research still has a foundation, and many scholars support the launch of project demonstrations.
The tokamak device researched and manufactured by Tang Jianjun solved the problem of perfect annular magnetic confinement.
In addition, the circulator m device manufactured by the Southwest Research Institute of Nuclear Industry, which is called an ‘artificial sun’, also successfully achieved ‘discharge’.
Although all the problems of nuclear fusion technology have not been solved, China has mastered the design, construction and operation technology of large-scale tokamak devices.
These are the basics.
…
Public opinion at home and abroad is not optimistic about nuclear fusion research.
Most people think that 'rumors are just rumors', and they are just rumors. Even if they are willing to do research, it is not easy to pass the argument.
This kind of super-large research project cannot be decided by one person. It requires the support of many institutions and scholars to carry out it. The first step is to conduct technical demonstration. The purpose is to discuss the problems that may be encountered in the research, whether there are solutions and follow-up research.
Issues such as division of labor.
If it cannot pass technical demonstration, that is, there are no reliable solutions to some problems, the project will not be started at all.
Some people don't see it that way.
For example, professors at Xihai University who are familiar with Wang Hao.
They also know that there are many problems in nuclear fusion research, some of which cannot be solved at the technical level.
However, in comparison, they are more willing to believe Wang Hao.
The nuclear fusion research project is undoubtedly related to Wang Hao. Since it is a project that Wang Hao participates in and leads, any technical difficulties seem to be no problem.
Some people react very quickly.
For example, Zhang Zhiqiang.
After Wang Hao returned to Xihai City from the capital, he did not rush to work. Instead, he accompanied Su Yingxue to rest at home for a few days.
Then he returned to Xihai University.
When he entered the office of the Mason Mathematics Laboratory, he had just sat down to read the information when he saw Zhang Zhiqiang walking in carrying a big box.
This chapter is not over yet, please click on the next page to continue reading! Wang Hao stood up and glanced at it, and said with confusion on his face, "Lego?"
"yes."
Zhang Zhiqiang put the Lego toys aside and said with a smile, "Isn't my sister-in-law about to give birth? I'll give you a gift in advance to congratulate you!"
"..."
Wang Hao looked at Zhang Zhiqiang with a strange expression. It was okay to give the child a small gift, but the problem was... the child was not born yet!
Lego?
This kind of toy is not suitable for newborn babies to play with.
In addition, Zhang Zhiqiang will take the initiative to give gifts?
Zhang Zhiqiang immediately revealed his true purpose. He said with a smile, "Wang Hao, we are best friends, right? For a project as big as nuclear fusion, you have to think of me..."
"Not to mention other high-end technologies, it's okay to participate in a project to build a simulation system."
Wang Hao shook his head helplessly, "This project is not certain yet. Besides, you took the back door..." Before he could finish his words, Zhu Ping and Luo Dayong pushed the door open and came in.
Zhu Ping's face was full of enthusiasm.
She came to Wang Hao's side and hugged his arm. Zeng said, "Wang Hao, if the nuclear fusion project can really be launched, you have to think of us..."
"I'll forget it."
"Dayong is also interested in joining the project, joining the math group or the calculation group."
Wang Hao turned his head and looked at Luo Dayong, almost writing the words "You don't care" on his face, but Luo Dayong turned a blind eye and gave him a look that said, "It doesn't matter who takes advantage."
I feel helpless now.
Wang Hao felt that he was being taken advantage of, so he quickly pulled out his arm, coughed lightly and said, "You don't have to do this."
"I'll talk to you directly."
"First of all, this project may not be passed. If the project is passed, an experimental base will be built in and around Xihai, and our laboratory will also be one of the participants."
"Although we may not be important participants, we will definitely be allocated some work for projects such as computer simulation systems and automatic control systems."
"This is a very large project, so don't worry about not being able to participate."
"Of course."
"If you want to lead a team to take on projects, or you have to build a team and apply yourself, it all depends on your ability."
After Wang Hao finished speaking, several people took a long breath. They really wanted to participate in such a major project. Just participating in it was an honor.
The atmosphere in the office suddenly became lively.
Zhang Zhiqiang patted his chest and said, "Da Luo, let me tell you, in this way, you and I, plus Teacher Qi Xiao and others, we will apply for an independent project together."
"At my level and with my qualifications, there will definitely be no problem if I prepare."
Wang Haodao, "I want to remind you, Brother Zhang. If you want to apply for a project independently, your competitors include the Institute of Information of the Academy of Sciences, the Computer Center of Shuimu University and other top mathematical computer institutions and teams."
"Compared to these top teams, you have to think about your advantages in advance and make adequate preparations..."
Luo Dayong nodded in approval, "Yes, what is your advantage?"
"Advantage, advantage..."
Zhang Zhiqiang opened his mouth forcefully, but did not speak for a long time.
Compared with ordinary mathematics and computer scholars, his qualifications and technical level are quite good, but compared with the top scholars in the country, his qualifications have no advantage.
So where are the advantages?
Luo Dayong said, "Old Zhang, you don't have to think about it, I've already thought of it for you."
"What advantage?"
Zhang Zhiqiang looked over with confusion.
Luo Dayong pointed to the top of his head, nodded seriously and said, "Baldness is your advantage. You have a roller skating rink in the middle, barbed wire fences on both sides, and scholars with the highest standards."
"With your image, if you stand in front of the expert judges, you will get ten points for your image first."
"..."
Zhang Zhiqiang touched the smooth top of his head and shouted with a dark face, "Yeah, it's decided, I'll go for a hair transplant tomorrow!"
…
The tech sector moves fast.
While the discussion was still going on in the media, the science and technology department had already organized the first technical demonstration meeting.
Many scholars who received the news were surprised.
Generally, large-scale engineering research projects require repeated internal discussions. During the process, some top scholars must be summoned to see what their opinions are. Only after there is enough support from scholars and institutions, a large-scale technical demonstration meeting will be organized.
This technical demonstration meeting can also be classified as an internal discussion, and it is still confidential to the outside world. However, there are several institutions that have received the information, and the number of participating scholars has exceeded a hundred, so it has long been out of the scope of a small discussion.
Institute of Physics, Institute of High Energy Physics, Academy of Sciences, Southwest Research Institute of Nuclear Industry, Institute of Nuclear Physics, Superconducting Materials Research Center...
etc.
Many large organizations have received the news.
They each sent a heavyweight expert team and gathered together in the main hall of the conference center where the demonstration meeting was held.
After entering the conference center, the scholars were still surprised, "I didn't even expect that the demonstration meeting would be held so soon."
"It seems like I just saw the news a few days ago..."
"Is this project related to Academician Wang Hao? There should be a direct connection."
Everyone else nodded in approval.
Nowadays, the main core technology for controlling nuclear fusion is no longer a secret. Many people know that the strong annihilation field generating device is suitable as a 'container' for nuclear fusion reactions.
In this regard, there are many reports abroad.
For example, the International Annihilation Theory Organization proposed that nuclear reactions can be studied in strong annihilation force field devices. First, the antigravity field can reduce particle activity, that is, control the reaction speed. Second, the outer strong annihilation force field can absorb energy.
, allowing the reaction vessel to withstand higher temperatures and energy.
While the scholars were discussing, Wang Hao, Tang Jianjun and others entered the venue together.
Wang Hao did not come alone. He temporarily formed a small team, including Tang Jianjun from the Institute of Nuclear Physics, Fang Yongsheng from the Institute of High Energy, Li Chun from the Institute of Nuclear Energy, Zhao Jiarong from the Center for Superconducting Materials, Ding Zongquan from the Wuhan Iron and Steel Research Institute, etc.
people.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Their respective research can be accumulated as technology for controllable nuclear fusion.
For example, Ding Zongquan's team used first-order iron to create a steel with a very high melting point and toughness. It also has certain magnetic properties and can be used as a material to create a spiral magnetic field on the outer layer of the container.
The leading party of the demonstration meeting is the science and technology department.
Teacher Xu came to the scene to set the tone for the demonstration meeting. He was the first to speak and said, "The content of our discussion at this meeting is the technical problems of controllable nuclear fusion engineering."
"This is a preliminary discussion meeting, so everyone should not feel pressured."
"If you have any questions or want to know, you can ask and talk. We have to discuss and study together to know what problems we will encounter in research and how to solve these problems..."
After Teacher Xu set the tone of the meeting, it was Wang Hao's small team's turn, with Tang Jianjun speaking as a representative.
His job is to elaborate on the existing technical foundation.
Tang Jianjun is very enthusiastic about the research on nuclear fusion. He very much hopes that the demonstration meeting can be passed. He even made a detailed ppt to list the main problems.
The first problem is ignition technology.
The ignition of nuclear fusion reactions requires very high-end technology. There is a saying in public opinion that "a hydrogen bomb requires an atomic bomb to detonate."
This statement is not an exaggeration.
When an atomic bomb explodes, the core temperature can reach as high as 100 million degrees Celsius in an instant, just reaching the temperature conditions for detonating a hydrogen bomb.
However, on the ppt made by Tang Jianjun, there is only one title on the ignition of nuclear fusion.
When he made the introduction, he skipped directly to the next question, "Let's look at the second question, high magnetic field environment manufacturing and reaction control..."
An old academician below reminded me, "Academician Tang, you haven't asked the first question yet."
"Although we already have ignition technology, the new reaction vessel is a strong annihilation field device with an anti-gravity field inside. How to achieve nuclear fusion ignition in an anti-gravity field?"
Everyone looked at Tang Jianjun on the stage.
Tang Jianjun smiled confidently and said, "Academician Zhou, this question can be skipped because we already have complete nuclear fusion ignition technology."
"Perfect nuclear fusion ignition technology?"
"right."
Tang Jianjun nodded seriously, "This ignition technology does not require restarting the equipment or internal intervention. It can ignite externally at any time."
After he finished speaking, he looked at Teacher Xu.
Teacher Xu nodded in approval, "Yes, we already have perfect ignition technology, so there is no need to discuss this issue."
"Hula..."
The venue was suddenly in an uproar.
All the scholars participating in the meeting did not expect that Tang Jianjun broke the big news just after taking the stage. They actually had a brand-new, so-called "perfect" ignition technology.
This technology doesn’t even need to be discussed?
Teacher Xu nodded in approval?
What does it mean?
This shows that the technology has been perfected and can solve any problem encountered in the ignition process!
"When did we have such high-end technology?" Many scholars couldn't help but discuss it. They were really surprised.
