It goes without saying that it is important to increase the Q value, which is the basis for the energy produced by a nuclear fusion reactor. In this regard, Chen Yue carried out research in several major aspects, such as reducing energy consumption, improving control accuracy, the completeness of nuclear fusion, and improving the accuracy of equipment.

Each of these aspects will involve a few dozen or hundreds of research projects. Each project will be studied by one or more specialized research institutes.

This research direction alone involves hundreds of large research institutions. These large-scale research institutions involve more upstream machinery factories, power plants, foundries, metallurgical plants, chip factories, transportation lines and so on.

Such a huge project, if it were not for Chen Yue's model, if it were to be done by human civilization, I don't know how many times more loss would have been made.

Equally important is the study of increasing the length of ignition time. It involves the stability of a nuclear fusion reactor. Chen Yue didn't want one day, a spaceship he was riding in would fuse and fuse, and then suddenly the fire would go out and he would never be able to fight again.

It's a bit better in a galactic environment, as it's easier to get supplies. If you are in interstellar space outside the galaxy, there may not be a single macroscopic matter in the surrounding range of several light-years, and then it can be regarded as heaven and not earth. Cornered.

This is mainly improved by more advanced lithium alloy materials, as well as tritium self-sustaining technology and plasma stability studies. This also involves a wide range of research institutes.

The overall installed capacity is related to the size of the reactor. Obviously, the larger the ship, the higher the overall capacity.

Needless to say, in terms of miniaturization, just like the nuclear fusion power station built by Chen Yue at this moment, covering an area of millions of square meters, no matter how big the spaceship is, it is impossible to have so much space.

These four research directions involve all aspects of the current Chen Yue science and technology system, and Chen Yue must integrate the entire scientific system, work together, and advance synchronously in order to finally promote the progress of research.

With all the satellites above the scale of the entire Jupiter system as the source of resources, Chen Yue did his best to push the heavy cart of science forward slowly.

Time passed slowly, and in the seventieth year of research, the second fusion power station with practical value was put into operation and began to be connected to the grid for power generation.

Compared to the first fusion plant, it has a footprint half as small, energy output is ten times higher, and energy consumption is reduced by one-third.

At this stage, fusion power plants do not have any advantages over nuclear fission power plants. Its overall efficiency is about the same as that of an ordinary thermal power station.

But it is still the same sentence, the upper limit of thermal power stations is here, and no matter how high the technology is, it cannot break through the limit. Although the level of the fusion power station is now the same as yours, the upper limit is tens of millions of times higher.

After another 20 years of development, I don't know how many spaceships have been broken, I don't know how many mineral resources have been consumed, I don't know how many iterations have been updated, and the comprehensive efficiency of the nuclear fusion power station is finally on par with the nuclear fission power station.

At this moment, Chen Yue's fusion technology has made great progress in four aspects: Q value improvement, overall installed capacity, reactor miniaturization, and ignition time.

The newly developed controllable nuclear fusion marine reactor has reached the performance indicators of the mature nuclear fission reactor in terms of volume, quality and stability.

That is to say, at this moment, Chen Yue can completely transform the current nuclear fission spacecraft into a nuclear fusion spacecraft, and these spacecraft will not have any performance degradation.

But, that's not enough.

It's just flat, which doesn't mean anything to Chen Yue. Chen Yue wants higher energy density, longer range, and higher acceleration ability.

At this moment, Chen Yue can already claim that he has completely mastered the technology of controlled nuclear fusion. It's just not that deep.

Time passed slowly, and in the blink of an eye, more than ten years passed. On this day, Chen Yue finally achieved a goal that he had never imagined before.

For the first time in history, the tritium produced by fast neutrons bombarding lithium alloys in nuclear fusion reactors exceeds the tritium consumed by nuclear fusion!

Prior to this, Chen Yue's state-of-the-art fusion reactor had been operating continuously for 16 years without a ceasefire. It is expected to be operational for at least 10 years.

However, even if it can operate continuously for 30 years, there is still a time limit. At that time, once the fusion reactor is de-fired, it will have to be re-replenished with tritium before it can be ignited again.

But now, with the output exceeding the consumption, it means that the tritium self-sustaining duration limit has been completely overcome by Chen Yue. From now on, as long as the equipment is not damaged, nuclear fusion can continue forever, and there is no need to worry about a ceasefire!

This major breakthrough made Chen Yue extremely excited.

Since then, Chen Yue's luck seems to have changed for the better all of a sudden, and several major problems have been broken through in just five years.

"Is this a lot of accumulation? Hundreds of years of research in thousands of large-scale comprehensive research bases have produced scientific data, and finally from quantitative changes to qualitative changes. ”

Chen Yue sighed with emotion, his heart full of pride.

Because all of this has only appeared under his persistent push.

The solution of these major problems has made the total energy supply per unit weight and volume of fusion reactors five times that of nuclear fission reactors for the first time.

But that's not the limit.

Chen Yue had a hunch that in another twenty years at most, this number would reach about twelve times.

Ideally, fusion produces about five times as much energy as nuclear fission with the same mass of fuel.

However, the nuclear fission reactor is converted into electric energy that Chen Yue can directly use, and the loss is large. Chen Yue's newly developed system, which is specifically designed to convert the energy of nuclear fusion reactors, can achieve smaller losses. In this way, there can be a situation where the fusion energy is 12 times higher than that of nuclear fission.

"Although it has not yet been developed to the limit, the time is now ripe for the construction of a fusion-powered spacecraft. It's time for a costume change. ”

Chen Yue made this decision that was extremely significant to him.

He did not directly modify the original nuclear fission spacecraft, because those ships were specifically designed for nuclear fission power and were not very suitable for nuclear fusion.

He developed a new spaceship, and after years of iteration and refinement, it was finally finalized and produced.

New structural layout, new materials, new power source, major upgrade of ion propulsion system, communication system, radiation anti-radiation system, heat insulation system, electronic control system......

The comprehensive performance of this nuclear fusion spacecraft is ten times higher than that of the original nuclear fission spacecraft!
