Xinghai Research Institute, in a quiet office near the scenic lake, Xu Chuan sorted out the work at hand.

He did not expect that the miniaturized and controllable nuclear fusion energy would usher in a breakthrough so soon.

In his planning, it may not be until next year to solve the new classic transportation problem of the stellarator.

After all, this is also a world-class problem, and the Planck Plasma Institute has been working on it for several years, in exchange for only increasing the engineering difficulty to reduce the loss of high-temperature plasma.

But even so, the original Spiral Stone-7X's new classic transport far surpassed the tokamak device.

This is a 'common problem' with stellarator structures, with complex chamber tracks bringing plasma turbulence control far beyond tokamak installations, as well as a high level of neo-classic transport.

I didn't expect the researchers of the Energy Research Institute to be so powerful and find a solution so quickly.

Sorting out the technical materials sent by Liang Qu, Xu Chuan carefully flipped through the solutions and methods in these research processes.

I just got a rough idea two days ago, but now I look at it carefully, and some of the ideas and solutions in it are still worth exploring in depth.

For example, the distribution of coils in the polar direction of the stellarator will produce various vacuum magnetic island shapes, destroying the edge magnetic plane topology.

Although the severity of this problem is not comparable to the high-level neoclassical transportation problem, if it is ignored, it will cause a magnetic surface disorder effect during the operation of the plasma, which will destroy the monitoring of plasma turbulence by the mathematical model, and eventually cause a serious accident.

In order to avoid edge effects, the traditional solution is to leave the last closed magnetic surface surrounding the plasma from the vacuum chamber wall, increasing the distance between the magnetic surface and the first wall.

But in this way, although the problem is solved, the volume of the stellar simulator will be much larger.

On the side of the Energy Research Institute, under the leadership of a researcher named Xu Yanghui, the polar cross-section of different hoop angles was rotated according to the rotation law by using the magnetic axis as the axis of rotation to obtain an equivalent calibrated polar cross-section under the rotation coordinate system, and an axisymmetric operation model was designed, which solved this problem.

This is a semi-detached idea from the engineering structure, through the mathematical model combined with the permanent magnet structure to complete the suppression of the edge magnetic plane topology problem, Xu Chuan faintly feels that aside from the controllable nuclear fusion technology, this method seems to be able to be used in other fields.

As for which field it was applied to, he couldn't remember it for a while.

Shaking his head, Xu Chuan came back to his senses, took out the notebook from his backpack, opened it, copied the relevant information, and created a new document.

Fingers clicked on the keyboard, and a condensed summary document appeared.

This is also his habit, every time he finds something that he finds useful or 'interesting', he will organize and save it.

He was able to solve all kinds of theoretical and applied problems at this age, relying not only on the knowledge brought by his previous life, but also on the huge ideas that this habit brought him.

After all, knowledge is always accumulated.

At this moment, there was a sudden knock on the door of the office.

"Please come in." Hearing the voice, Xu Chuan shouted without raising his head.

"Academician Xu, I'm busy, or I'll come over later."

In the office, a warm voice sounded, and Xu Chuan looked up to see that it was Wen Yuanhang, who was working in the daily work of the Management Institute.

Nodding at him with a smile and saying hello, he said, "Just wait a minute, I'll finish sorting this thing." ”

Hearing this, Wen Yuanhang also sat down and said with a smile: "Don't worry, Academician Xu will be busy first." ”

Nodding, Xu Chuan took his attention back, and after perfecting the last bit of things, he looked at Wen Yuanhang who was sitting on the sofa, and asked with a smile, "Is there anything that Dean Wen is looking for me?" ”

Wen Yuanhang smiled and said, "There is something. ”

After a pause, he continued: "First of all, the breakthrough of our research institute's miniaturized and controllable nuclear fusion technology, I would like to ask, judging from the current situation, when will the first small reactor come out?" Academician Xu, do you have any approximate data or estimates? ”

It is not only the researchers of the Energy Research Institute who pay attention to the progress of miniaturized and controllable nuclear fusion technology, but also Wen Yuanhang, who manages the daily work of the research institute as a science and technology expert, must also keep an eye on the progress of the major projects of the institute.

On the one hand, it is to cooperate with the relevant research work and affairs, and on the other hand, it is to feedback the progress and situation of some important projects, such as miniaturized fusion technology and aerospace engines.

After all, these things involve all aspects of national development, from national defense to people's livelihood.

This breakthrough in miniaturized and controllable nuclear fusion technology is the most typical example.

Whether militarized or commercialized, its emergence can completely change the world.

If it takes a long time for the infinite energy brought by controlled nuclear fusion technology to change the world little by little, then the impact of miniaturization technology on the global pattern is tantamount to a short period of time.

Whether it is aircraft carriers, heavy bombers and other equipment, relatively speaking, only a simple transformation is needed to obtain a strategic-level combat equipment with almost unlimited endurance, which is undoubtedly greater than the civilian fusion reactor for the impact of the world situation.

Therefore, after confirming that the miniaturized and controllable nuclear fusion technology has made a breakthrough, Wen Yuanhang came to this person's office as soon as possible to find out about the situation and sort out the information for reporting.

Behind the desk, Xu Chuan thought for a while and then said: "The progress of the first miniaturized fusion reactor has been theoretically completed so far, and the rest of the progress depends on the production and assembly of relevant parts. ”

After a pause, he then asked, "Didn't we design and order parts for a small pile from major parts suppliers, how is the production of the relevant parts?" When will it be complete? ”

Hearing this, Wen Yuanhang quickly replied: "I have followed up on this matter, but the latest situation was ten days ago, and the current production of small reactors is at 60% according to the overall progress, and the production progress of the most critical field coils and magnet windings is slow. ”

"Judging from the progress ten days ago, it will take about two months for the production of the whole set of equipment."

Hearing this, Xu Chuan shook his head lightly and said, "It's a little slow." ”

The customization of the small pile, after the arrival of the Spiral Stone 7X, they actually began.

If it is a tokamak device, I am afraid that the relevant equipment will already be assembled, and it will take two months for the stellar simulator to be fully produced.

Wen Yuanhang smiled bitterly, and said helplessly: "No way, the production difficulty of the stellar simulator component is much greater than that of the tokamak device, if it weren't for the fact that you improved the design of the permanent magnet stellar mimic before, and the modularization of the magnet winding greatly reduced the production difficulty, according to the standard of the Spiral Stone-7X, I'm afraid this time will have to be extended by two or three times." ”

Xu Chuan shook his head and said: "Two months, according to this situation, counting the assembly time, the completion of the first miniaturized fusion reactor may not be until the beginning of spring in February next year." ”

Not only production, but also the assembly of the stellarator is also a troublesome matter, the complex structure and twisted coil must be accurately positioned to each position without the slightest deviation, which is much more difficult than the tokamak device.

As for the progress of the small reactor, Xu Chuan felt that it was a little slow, but there was no way.

This is an inevitable stage in the research and development process of a new technology, and this problem can only be solved by waiting for the production scale to be systematic.

For Huaguo, an industrial power, this is probably the first time that the speed of production cannot keep up with the development of theoretical applications.

On the other side, Wen Yuanhang, who was sitting on the sofa, didn't feel this way.

From tomorrow to February, the time interval will be only five months.

Five months to complete the production and assembly of a miniaturized and controllable nuclear fusion reactor is still in the stage of scientific research and experiments, which is fast enough.

After recording the time information, he then spoke: "What about the performance parameters, Academician Xu, whether this miniaturized fusion reactor is efficient enough to provide energy for large aircraft carriers, strategic bomber fighters, space stations, and other equipment." ”

"Or can it be loaded on aircraft carriers, strategic planes, and so on?"

Hearing this question, Xu Chuan smiled and said: "The purpose of my research on miniaturized and controllable nuclear fusion reactors was to install them on the space shuttle to provide energy for the aircraft. ”

"Although I don't know much about the structure of the aircraft carrier and strategic aircraft you mentioned, if there is enough space, it is theoretically no problem to install it."

"As for power, don't worry too much about this, although the power ceiling of a small reactor is much lower than that of a large Daybreak fusion reactor, it is more than enough to provide energy for equipment such as the Space Shuttle."

"After all, you have to know that the Daybreak Fusion Reactor can now afford to supply electricity to the entire Sujiang Province. Fusion reactors use energy much more efficiently than fission reactors, and the two are not at all an order of magnitude. ”

After a pause, Xu Chuan continued: "However, there are some big problems that need to be considered when small reactors are applied to aircraft carriers. ”

Hearing this, Wen Yuanhang hurriedly picked up the notebook from the tea table, held the ballpoint pen, and said, "Academician Xu, please speak." ”

After a deep sigh, Xu Chuan spoke: "First of all, there is the control of the fusion reactor. ”

"At present, the controllable nuclear fusion technology, whether it is the dawn fusion reactor or the Huaxing stellarator, is the magnetic confinement route, and the magnetic confinement is inevitably inseparable from the restraint and control of the plasma turbulence inside the reactor chamber."

"This is a big problem, and you must know the specially built supercomputing center at the Daybreak Reactor."

"Although the stellarator has a great advantage in plasma confinement, which greatly reduces the difficulty of running the plasma turbulence numerical control model, it also needs the supercomputing center to provide computing power in any case."

"On the space shuttle, I am going to customize a special supercomputer to complete this task, which can reduce the volume demand for supercomputing, and with the energy generated by the small reactor itself, it should not be a big problem to solve the computing power problem."

"But in this way, the space, weight, and carrying capacity on the space shuttle will be reduced or increased accordingly, which is not a big problem for the space shuttle for scientific research."

"But if it's for fighter jets, I'm afraid it will have a huge impact."

On the sofa, after Wen Yuanhang quickly recorded this question, he was about to open his mouth, when he heard Xu Chuan on the other side add a sentence.

"Don't think about solving this problem remotely over the wireless, it's impossible."

"The delay problem caused by signal transmission is fatal to the control of high-temperature plasma turbulence, and once the reactor is out of control, even if it is a small reactor, tens of millions or even hundreds of millions of degrees of ultra-high temperature will cause great damage"

Hearing this, Wen Yuanhang opened his mouth, and was held back before he could say anything.

He had just wanted to ask if he could solve this problem wirelessly.

On the other side, Xu Chuan looked at Wen Yuanhang, who had a strange face, and asked curiously, "What's wrong?" ”

Wen Yuanhang shook his head awkwardly and coughed dryly: "It's okay, I recorded this problem, and there is more." ”

"And power generation, energy conversion."

In the office, Xu Chuan briefly mentioned some key points of the small reactor to Wen Yuanhang.

It has to be said that although in terms of volume, the volume of the small reactor can be the size of a medium-sized SUV car from the current data, it is still an unrealistic problem to fully apply it.

Whether it is the control scheme, or the supporting power generation equipment, or the volume itself, it is a problem to promote it.

However, Xu Chuan has no extra choice, and technological breakthroughs and changes come little by little.

With the current foundation, it can be said that it is very, very good to be able to achieve this level, and there are many places where it can be applied.

But if you think about the kind of fusion battery in science fiction or science fiction movies, or the size of the current nuclear fission battery, it can only be said that with the current technology, it is still too far away.

On the sofa, after Wen Yuanhang recorded everything, after confirming that there were no omissions, he closed the notebook and carefully put it in his arms for safekeeping.

Immediately, he stood up, saluted to Xu Chuan, who was sitting behind the desk, and said solemnly:

"Although I am not qualified to express my gratitude to you, I still hope to be able to say thank you on behalf of the people of the whole country and the country, you have worked hard!"

Behind the desk, Xu Chuan smiled, waved his hand and said, "Don't be so polite, this is my research work." ”

Although he knew what Wen Yuanhang's gratitude was for, for him, if his research could contribute to national defense, he would also be happy.

Compared to the purely anti-war scholars of his grandfather, Grothendieck, he did not care much about the use of his research in military affairs.

After all, when the motherland is strong, the safety of compatriots who travel abroad will be more guaranteed, both at home and abroad.

From a personal point of view, his choice, at least in his own opinion, is not problematic.
