Chapter 133: Three Difficulties

Yu Yifeng's first reaction was: Is it possible to directly use uncontrollable nuclear fusion?

But then again, humanity doesn't know what to do with the "unsolvable" problems of controlled nuclear fusion alone......

This is completely a huge shackle in theory, and no one knows how many years it will be before a genius will emerge to solve these theoretical problems in one fell swoop. X

Could it be that in this case, people really want to drill the horns and continue to take the road of "magnetic restraint"?

Scientists aren't that stupid!

Since "controlled nuclear fusion" is too difficult and complicated, they have frantically come up with another option......

Uncontrollable nuclear fusion!

This is also the more feasible plan that the great sage of Knicks felt before his death ...... "uncontrollable nuclear fusion", this kind of thing has actually been realized by human beings a long time ago, isn't that a hydrogen bomb!

Why should we be obsessed with "controllable"? Can't you use the energy of the hydrogen bomb?! If the energy of the hydrogen bomb can be utilized, won't it also become controllable?

That's what it is...... What this group of scientists really thinks!

Yu Yifeng's scalp tingled when he heard this, and for the first time, he felt that this world was simply too crazy.

But in the next conversation, he knew...... It's not just this world that's crazy!

This idea has already arisen in the time of the earth!

In the sixties and seventies of the twentieth century, when nuclear research and development were at a high level, the Soviet Union and the United States discussed this plan: they tried to dig an underground cave deep in the mountains and old forests, repeatedly carry out nuclear explosions in the caves, and then use the heat of the nuclear explosion to generate electricity......

"According to calculations, as long as 1,000 nuclear bombs with a TNT equivalent of 3,000 tons can meet the power supply problem of a medium and large city...... According to our output, more than 100,000 pieces a year will not be a problem. ”

Professor Ding Yidong said with a smile: "Of course, it was a plan 70 years ago, and there are still a lot of problems that have not been solved, so it will not be solved in the end." ”

"Nuclear bombs were quite expensive for the construction at the time, and using them to generate electricity was completely putting the cart before the horse. Moreover, the large-scale manufacture of nuclear bombs can easily cause nuclear leakage, and if a nuclear bomb falls into the hands of terrorists, it is simply unimaginable......"

"But for us, there shouldn't be that problem. There should be no terrorists in Noah's society......"

"We can make the nuclear bomb bigger and stronger, or we can replace the underground cavern with a spherical reactor, so that we can collect more energy."

Yu Yifeng looked at Ding Yidong's weird smile and shuddered in his heart. The old man has been getting mader and crazier since he regained his youth.

I guess he has been thinking about this plan for a long time, right?

But other scientists were supportive, especially the conservatives like Dr. Felix.

Don't...... Is it really possible?

The more he thought about it, the more bizarre he felt, but he still kept enough calm and asked a series of questions: "Is this plan really feasible, have you strictly researched it?" You can't just tap your head to decide the direction of the entire civilization! ”

"And ...... Where does the tritium element come from in the hydrogen bomb explosion? Is it with helium-3 bombs? Or an ordinary four-hydrogen nuclear bomb? The equivalent is too big, right? What about the cost of laser ignition? ”

“…… Have you considered security? What if that boiler explodes? ”

The scientists looked at each other, and in fact, they had been discussing this scheme for a long time, and it was more reliable than magnetic confinement.

However, they felt that Yu Yifeng's words were to the point, and as a qualified leader, a cautious attitude was really the most important.

One of the experts immediately took the report in his hand and said: "Captain, regarding your question, we have compiled the relevant data. ”

"With uncontrollable nuclear fusion, it doesn't mean that you can do it, it actually has certain difficulties, and three conditions need to be met."

"First, the study of nuclear bombs must be very in-depth. The amount of energy used to build a small nuclear bomb must be much smaller than the amount of energy released by the nuclear bomb. Otherwise it's a joke to generate electricity with a nuclear bomb! ”

Yu Yifeng nodded, this is also true.

Nuclear bombs are not ordinary missiles, and they are very expensive to manufacture, for example, to make an atomic bomb, high concentrations of uranium-235 are used, and purification of these highly enriched uranium requires a lot of energy.

The whole energy used up is even more than the energy released!

Besides, it is impossible for humans to collect all the energy released by nuclear bombs, and it is good to be able to use 10% or 20%!

In this way, if the energy is spent less than the revenue, then the power generation plan is sure to fail.

Seeing Yu Yifeng's pensive appearance, the expert continued: "Second, the raw materials of the nuclear bomb must be very extensive, not rare tritium, and preferably helium-3...... Otherwise, it is still unsustainable. ”

"We still have some helium-3, but the reserves are not very large, less than a thousand tons at the moment...... This is also a problem. ”

"Third, there is the problem of the reactor, of course, we can dig a hole in the ground to explode in it, but in this way, most of the energy will be transmitted to the ground, and the utilization rate of the nuclear explosion energy will be lower."

"And if you detonate a nuclear bomb in a cave, the cave will melt down after a long-term explosion, and it may even cause a large-scale earthquake...... Locations need to be changed frequently. ”

This list of difficult points shows that this group of scientists has indeed thought carefully about this problem.

Yu Yifeng frowned and pondered, undecided.

I saw the scientist say again: "Actually, in the final stage of the Nix civilization, it also thought about using this scheme to obtain energy...... But they don't have enough tritium or helium-3, so they don't have enough raw materials for nuclear bombs, not enough raw materials for ignition. ”

"But we have a four-hydrogen nuclear bomb, which has a wide range of raw materials, and only a small amount of tritium or helium-3 can be detonated as an ignition agent. Though...... Belch...... Equivalent...... If it's a little bigger, then just make the reactor bigger! ”

"Our technology for the production of nuclear bombs...... It should be quite mature, and the energy consumption is relatively small, which is a big advantage. ”

Yu Yifeng didn't know what to say anymore......

The technology of building a nuclear bomb is awesome, and it seems to sound good...... What is this? Is this also a plus?

Normal civilization is in peaceful mode in the later stages of development, and it will not be as crazy as the new human civilization to study nuclear bombs.

Especially during the Earth period, the hydrogen bomb was a weapon that was slowly phased out because of its high maintenance costs......

"As long as the deuterium-deuterium fusion reaction is sufficient, there is no need for a four-hydrogen nuclear bomb." Professor Ding Yidong added: "The critical reaction temperature of this new type of nuclear bomb is only 3-500 million degrees, which is much lower than that of the four-hydrogen nuclear bomb, and the yield can be smaller, completely controlled within one million tons of yield......"

Yu Yifeng's head was sweating, what do you mean as long as 500 million degrees......

As long as 500 million kWh......

"The four-hydrogen nuclear bomb costs more than 1 billion kWh! The yield can only be larger, and a smaller deuterium bomb is a better choice! ”

The study of nuclear bombs has become a unique technology of the new human civilization, which has greatly surpassed the Nix civilization and the earth civilization.

After all, with the solar explosion as the enlightenment teacher, human research on nuclear reactions has indeed gone one step further.

However, the structure of this new type of nuclear bomb is similar to that of the four-hydrogen nuclear bomb, which requires helium-3 bombs or hydrogen bombs to ignite, and the yield cannot be lowered, at least at the megaton level, which is a major difficulty.

What can eat a nuclear bomb with a megaton yield?

A nuclear bomb with a yield of one million tons, with a killing area of 150 square kilometers, can blow up a city!

He Yu Yifeng was really convinced...... r
