283 - Gain factor Q value

Naturally, Chen Chen did not need to host the press conference on the Xingtian project. He had just chatted with Xia Yin when Xiao X suddenly sent a message.

On the mobile phone, Xiao X sent a message: Just a few minutes ago, during the experiment of the inertial confinement reactor, an atmospheric pressure leak was suspected.

So, Chen Chen couldn't care about Xia Yin anymore, turned around and left in a hurry.

After stepping out of the black light dome, Chen Chen quickly got into Cheng Chao's car and said at the same time, "Chaozi, hurry to the steeple as fast as possible, hurry up!"

But before he finished speaking, Xiao X's voice came from the car audio again: "Your Excellency Godfather, in fact... it was a data error just now, and everything in the inertial restraint reactor is normal..."

Chen Chen: "..."

Cheng Chao looked at Chen Chen curiously with the rearview mirror, "Boss, are you still going to the steeple?"

"Go, I'll drop by."

Chen Chen waved his hand and said helplessly.

Immediately, the vehicle started slowly and left the black light dome.

The inertial confinement reactor mentioned by Little X is a nuclear fusion device developed by Chen Chen based on the plane technology of "Bliss Space" years ago. From the end of last year until now, various consortiums have provided him with a large number of high-precision laser components according to Chen Chen's request. .

Chen Chen even discovered that some of these laser components turned out to be spare parts for the official NIF facility in North America. I don't know what kind of means these families used, even the laser generator of the NIF project was brought over.

After the reactor was assembled, after several months of experiments, the inertial confinement reactor had successfully ignited 13 times in a row, causing the deuterium-tritium fuel inside to undergo nuclear fusion reactions, forming a miniature sun with a diameter of one centimeter.

Not only that, after multiple parameter corrections, this inertial fusion reaction can be maintained for more than five minutes, and the Q value has easily exceeded the number of 10, reaching as much as 18 points.

Seeing that the world's first truly controllable nuclear fusion reactor was about to succeed, but when the atmospheric pressure leaked at the very moment, Chen Chen was naturally panicked.

Fortunately, it was just a false alarm.

Half an hour later, when Chen Chen took the elevator to the Minaret Experimental Base, he happened to see a newly built giant building standing in the southwest corner of the underground space.

This is a shed-like building similar to an assembly line factory.

At this time, dozens of black knights were coming in and out here, looking very busy.

This shed-like building is Chen Chen's new inertial constraint power station.

Different from nuclear fission power plants, nuclear fusion is a completely clean energy source. The substance produced after the reaction is only water, and because of the harshness and particularity of nuclear fusion, once the reactor fails, the reaction will automatically stop, there is no need to There will be nuclear radiation proliferation and other accidents.

Therefore, Chen Chen was very relieved to build the nuclear fusion factory in the underground steeple experimental base.

As Chen Chen walked into the workshop, what caught his eyes was a huge cylindrical building with a diameter of more than 30 meters in front of him.

The whole body of this building is made of reinforced concrete, and inside this building with an outer wall as thick as five meters is the inertial confinement reactor.

Who would have thought that at this time, inside this huge building like a building, there is a high temperature of hundreds of millions of degrees and an ultra-high pressure of more than 100 billion atmospheres that the earth has never seen before?

Chen Chen looked at the console beside him, then raised his head and asked, "X, how is the situation now?"

"Today, fifteen consecutive ignitions have been successful, and the reaction time of the inertial confinement fusion reactor has exceeded one hour. So far, the Q value has exceeded 20."

"Has the lack of stability been resolved?"

Chen Chen couldn't help raising his eyebrows when he heard the words, "I remember that in the previous experiment, the room temperature superconductor couldn't completely stabilize the plasma, right?"

Xiao X replied, "The reason why it is difficult to stabilize is that once nuclear fusion occurs in the plasma, it will become very turbulent, and the reaction will be terminated due to scattering. Offer a reward, and modify the background data, so that the reward for my question is worth hundreds of experience points."

"That is to say, whoever can solve my bounty problem can get more than a hundred points of experience on the website."

"In order to gain experience, those high-energy physicists offered suggestions and came up with 341 methods, but in my opinion, they are useless."

"In the end, I almost got a really useful answer from an ID named 'Sun Sakikawa, the boy of Zhaohe'—"

Little X continued, "Add 0.1mg of heavy elements into the deuterium-tritium fuel pellets as the core, because the heavy elements will gather toward the center of the pellets, so after the fusion reaction occurs, the pellets will maintain a certain high temperature and high pressure state, maintaining Plasma temperature and pressure toward the center of the sphere."

"Because this pressure is maintained, the ball does not undergo all-round fusion immediately, and part of the energy of the plasma on the surface will be released into the surrounding reaction chamber, keeping the two in balance, and the ball will neither expand nor Shrink, and the fuel of the ball will be squeezed to the surface to participate in the reaction in an appropriate amount, making the reaction more durable and stable..."

"It's so simple?"

Chen Chen showed surprise, "Could it be that that person is a genius in high-energy physics? X, can you find out his real identity?"

"I've already checked. This person has opened a studio with only one person in charge of writing soft articles, online trolls, and trademark squatting."

"..."

It has to be said that no matter how sophisticated the nuclear fusion equipment copied by Chen Chen is, and no matter how well he restores the technology of the "Elysium" plane, the technology generation gap always exists.

But what Chen Chen didn't expect was that Little X found another way and solved a big problem by brainstorming. Although doing so would cause the power of the reactor not to reach the level of the original version, it was enough for Chen Chen.

In fact, the fundamental meaning of the so-called inertial confinement nuclear fusion is to hit the energy of multiple lasers on a very small target containing nuclear fuel in a very short period of time to create a miniature nuclear fusion and release a large amount of energy .

After the first nuclear fusion is over, the reactor will automatically load new fuel targets, and in this way, nuclear fusion will be ignited again and again, thereby obtaining a large amount of energy.

The real difficulty here is that in addition to the supersymmetric laser elements, there is another point that requires the laser generator to consume a huge amount of electricity to ignite and form a fusion reaction.

That is to say, even if it is not enough to form a nuclear fusion reaction, the energy produced by the nuclear fusion reaction must be greater than the energy consumed by the ignition of the laser generator.

Therefore, here we have to mention the gain factor of nuclear fusion energy - "Q value".

The ratio of "output energy to input energy" is called "Q value". If Q is greater than 1, it means that "output is greater than input". Counting the cost, if it is a steam turbine that burns a boiler, the "thermal efficiency" is about 40%-70%. Counting some other losses, it can be roughly considered that Q=2.5 is a real cost price.

That is to say:

At Q0, the fusion reaction is realized, which is a sign of a breakthrough in the principles of human fusion reactors.

At Q1.0, the output energy is greater than the input energy, which is a sign of "break-even".

Q2.5, the output energy is still greater than the input energy after it is converted into electrical energy, which is the true sign of a breakthrough in the "practical application" of nuclear fusion.

Q50 is a symbol of "commercialization" that can realize profitability after the output energy is converted into electric energy.

Therefore, there is often a saying in the high-energy physics community: "Controllable nuclear fusion without talking about the Q value is actually playing hooligans."

And the Q value of Chen Chen's inertial confinement fusion reactor at this time has been raised to as much as 20, and the maintenance cost is already more than enough.

The only regret is that Chen Chen did not use the method of "boiling water" to generate electricity, because the underground space is insufficient to withstand a large amount of heat emission, so Chen Chen used the "Magnetic Fluid Power Generation" technology with low power conversion efficiency.

This technology is not a technology in the plane of "Elysium", but one of the existing technologies in reality, and its principle is also very simple.

The miniature sun in the reactor is actually a high-temperature plasma confined by a magnetic field, and the plasma is also a charged particle system composed of positively charged particles and negatively charged particles. According to the Lorentz force, as long as the positive and negative The particles of charge are concentrated to the two-pole conductors, which can generate a potential difference, and then as long as the wire is connected, the current can be directly output.

The advantage of this magnetic fluid power generation technology is that it is simple and easy to operate, and there is almost no technical difficulty. The disadvantage is that the power conversion efficiency is not high. Otherwise, the Q value of the inertial confinement fusion reactor at this time may have exceeded 50. .

You must know that the nuclear fusion reactors in the world's top nuclear fusion reactors can also maintain a Q value of around 1.5. There is still a long way to go to truly achieve a self-sufficient 2.5.

But no matter what, Chen Chen could at least be sure that his nuclear fusion reactor in the Minaret Experimental Base had officially succeeded, and it would also be the first truly mature nuclear fusion reactor in human history.

According to Xiao X's calculations, the reactor's output power can reach up to 200,000 kilowatts. Although it doesn't look like much, the energy it consumes is only a drop in the bucket, far more cost-effective than nuclear fission power plants.
