Four days is not a long time, and with the efforts of the Energy Research Institute and the Nuclear Industry Group, the first domestic small controllable nuclear fusion reactor was officially completed.

In Xu Chuan's view, this small controllable nuclear fusion reactor should be called a compact fusion reactor.

Because it is completely unable to reach the technology of miniaturization.

A truly miniaturized fusion device should be able to break through the limit of meters and be installed on various vehicles such as cars, airplanes, and ships.

Of course, there are smaller ones, but that one can't be called a fusion device, it's more appropriate to call it a 'fusion battery'.

But for human civilization, or they who are researching miniaturized and controllable nuclear fusion technology, as Liang Qu said, there is no way forward on this road, and everything has to be groped forward in the dark.

Even if you haven't even done miniaturization, you just think about fusion batteries, which is even more impossible.

Even when he was reborn, he didn't know how to go on the road of miniaturized and controllable nuclear fusion.

After all, in the era before the rebirth, controlled nuclear fusion technology has not been realized, so how can we talk about miniaturization?

However, he has an extra twenty years of time, and he still has some new insights and controls for the future direction.

This year-on-year downsizing of the Daybreak fusion reactor, which has been successfully commercially operated, is undoubtedly the most worthwhile way to try.

It's just that, to be honest, Xu Chuan is not very optimistic about the road of shrinking the dawn fusion pile.

Although the Daybreak device has achieved controlled nuclear fusion technology, to be honest, it is actually a trick, and there are some problems that have not been solved at the root cause.

For example, the problems of plasma magnetic surface tearing, distortion, plasma magnetic island, etc., in fact, have not been completely solved, but are forcibly pressed down by superconducting materials with strong critical magnetic fields and changing the structure of the magnetic field in the outer ring of the fusion reactor.

It is undeniable that it has been able to achieve stable operation in a large fusion reactor, but no one knows whether the scaled-down device will encounter these problems that have already been solved during operation.

But no matter what, he had to try.

After all, the development of science is through the accumulation of data little by little, and then research, and finally succeed.

Without past data and mistakes, how can we usher in the final fruits of victory?

Of course, the small device built this time is not simply to collect data, and Xu Chuan and others still have a glimmer of hope for whether it can achieve a compact fusion reaction.

After all, theoretically speaking, there is still some hope for the miniaturization of the miniaturized equipment that reproduces the dawn fusion device.

If it succeeds, it will not be able to be applied to the space shuttle, but it will be enough to be applied to an aircraft carrier.

The five-meter-five-meter*five-meter core reactor, even with the addition of supporting control and power generation equipment, has enough space on the aircraft carrier to load.

An aircraft carrier equipped with a fusion device as a power source can be said to be a real carrier that never sets.

This is enough to give the Xinghai Research Institute a try.

On March 3, with the efforts of the Xinghai Research Institute and the Nuclear Industry Group, the final commissioning of China's first miniaturized compact fusion reactor was completed.

In the research institute based on the transformation of Qixia's controllable nuclear fusion experimental engineering, even the general control room has not changed, and everything has transitioned so naturally.

Standing in this general control room again, Xu Chuan gave the order to start the test as a matter of course.

With the transmission of orders, everything here seems to go back to the time when controlled nuclear fusion was studied.

The crews in the control rooms were busy again.

Adjustment of the magnetic field of the external coil, cooling of liquid nitrogen and liquid helium, formation of a confined magnetic field, and injection of helium three simulated raw materials

One familiar work after another unfolded, only this time, they were standing on the shoulders of giants, looking out into the farther future.

By the time the first simulation was completed, it was already afternoon.

The collected data was processed overtime by the supercomputing center at the Daybreak Demonstration Reactor Project, and because of the relevant experience, the supercomputing center completed the analysis work the next day.

The processed data was sent back to the Xinghai Research Institute, and Liang Qu, the director of the Energy Research Institute, personally delivered it to Xu Chuan.

"How's it going?"

After receiving the processed data, Xu Chuan asked casually.

"Not optimistic."

Liang Qu shook his head and replied, "There are a lot of problems that have appeared in this operation. ”

"For example, the plasma magnetic plane tearing, twisting, and plasma magnetic islands in the reactor chamber are too serious."

"I didn't expect that after the fusion reactor became smaller, these problems that had been solved would appear again."

"And this is still helium trihydrogen simulation experiment data, if the real deuterium and tritium raw materials, I can't imagine what the result will be, directly explode and tear the entire fusion reactor to the big explosion?"

Xu Chuan flipped through the report in his hand and listened to Liang Qu's report.

Judging from the experimental results, this miniaturized and controllable nuclear fusion experiment can be said to be a complete failure.

As he had expected, the same problems that had been solved on the Daybreak fusion device reappeared in the shrinking fusion reactor.

The miniaturization of the tokamak route is likely to be really impossible.

After flipping through the test report in his hand, Xu Chuan put it on his desk, and after thinking for a while, he said with a smile: "Since the tokamak route doesn't work, then it's better to change the route." ”

Hearing this, Liang Qu was directly stunned, and hesitated for a long time before asking, "Change?" A different route?? ”

"Do you mean we're going to abandon this little fusion device that we just built altogether?"

He thought that the boss would find a way to solve these problems, after all, with his mathematical ability, it should be promising to solve problems such as magnetic plane tearing, twisting and touching, and plasma magnetic islands.

As a result, I didn't expect him to directly change the research route with one mouth?

Isn't that a bit of an exaggeration?

If you change the route directly, this means that all the investment in the early stage is basically wasted.

Xu Chuan smiled, thought about the language for a while, and then said: "Judging from the experimental data, the main problem of this test is that the problems of magnetic surface tearing, distortion and touching, plasma magnetic islands, which have not been completely solved before, have erupted again. ”

"This is a fatal flaw and a problem that the Tomamak device cannot solve."

After a slight pause, he looked at Liang Qu with a puzzled and tangled look on his face, as if he knew what he was thinking, and said with a smile:

"Don't think I can mathematically solve the problems of magnetic plane tearing, distortion and plasma islands. I tried it back in the days when I was working on the Daybreak fusion reactor. ”

"If I could, I wouldn't have let these problems stay until now."

"This is not a mathematical problem, but in the structure of the tokamak device itself, its overall structure remains unchanged, no matter how we adjust the angle and direction of the outer field coil, it is impossible to eliminate the problems of magnetic surface tearing, twisting, and plasma magnetic islands."

"Given the uncertainty of the current inside the plasma, it would be difficult to control the magnetic field inside the reactor even if we could perfectly construct the magnetic field we needed through the outer field coils."

"If it's a large tokamak device, we can also perform micromanipulation with a strong magnetic field and a mathematical model. But the small size of the tokamak, I'm afraid we can't react until it breaks through the first wall after it happens. ”

Hearing this, Liang Qu's face showed a look of shame and embarrassment, and after thinking for a while, he opened his mouth and asked, "If we change the route, which one can we change, the stellarman?" Ball beds? Counter-field tightening? Or do you abandon magnetic constraints and go to inertial constraints? ”

The stellar simulator was denied by this big guy in the early days, and the pebble bed also has the shortcomings of the tokamak in this regard, while the technology of the anti-field hoop is not mature, too niche, as for the final inertial constraint, to be honest, there is not much research in China in this regard.

For a while, he really didn't know which route this big guy wanted to follow.
