Hand rubbing nuclear fusion live in the wilderness

Chapter 443 Manufacture of Nuclear Weapons

The separation and purification of uranium 235 is a matter of course for South Korean won.

It would be a little more troublesome if he didn't have information about various resources and mineral deposits around the world and the X-1 industrial robot required him to do it himself, but it was just a little more troublesome.

After mastering the information of various resources and mineral deposits around the world, the problem of the source of raw materials is completely solved.

If it were before, it would be much more troublesome to mine the uranium mine in Inner Mongolia than it is now.

Although the grade of that uranium mine is relatively good, compared with the super uranium mine in Xijiang, it is much lower, and the uranium grade is only in the single digits.

To extract enough uranium 235 from this grade of uranium ore, the amount of raw ore required cannot be handled by a solution of [-] to [-] tons, and the amount must be increased by at least ten times.

To deal with such a large amount of liquid, what is needed is a factory, not several pools and water pumps.

After owning the intelligent industrial robot, the problem of labor force has also been solved, otherwise, the extraction of uranium 235 alone would consume a lot of his time.

After the uranium 235 used to make nuclear weapons was separated, Won did not delay, and directly started to make nuclear bombs to complete the mission.

Although there are still more than two months left in the Starlink mission, it is still necessary to leave some time just in case.

The 75 kilograms of uranium 235 extracted were all used to make a nuclear weapon, and the won was not prepared to save some for himself.

The requirement for the Civilization Guardian branch chain task is to create a nuclear fission weapon or nuclear fusion weapon, and the explosive power is required to be no less than [-] tons of TNT equivalent.

A nuclear weapon with an equivalent of 235 tons of TNT does not require much uranium-[-].

But the 75 kilograms of uranium 235 he extracted is not too much to put into nuclear weapons, and it belongs to the low-yield-medium-yield intermediate level.

The "Little Boy" nuclear bomb that the United States dropped on the small island country back then had an equivalent of 1.2 to 1.5 tons of TNT explosives and used 65 kilograms of uranium.

This is a very good reference data for the won.

The requirement for the task of guarding the branch chain of civilization is that the explosive power is not less than [-] tons of TNT equivalent, so the Korean won will be manufactured with this ton.

Not less than [-] tons of TNT equivalent, to ensure that he can complete the task.

But it won't exceed much, because the nuclear bomb will cause severe nuclear radiation after the explosion.

Even in the uninhabited desert, there is still an ecological environment, and the ecological environment of the desert is more fragile than places such as forests and grasslands.

However, a dead fellow Daoist is not dead, and compared to other places, the desert is undoubtedly the most suitable place to detonate a nuclear bomb.

It's not that South Korea has never thought of detonating a nuclear bomb in space, after all, there is no air in space.

Without air, there would be neither a mushroom cloud phenomenon nor a huge air shock wave that would destroy everything with an air shock wave.

After the nuclear weapon is detonated, its power will be greatly reduced.

But after thinking about it, he gave up the idea.

On the one hand, although he now has the ability to send a spacecraft into space, he cannot leave the earth too far.

On the other hand, countless charged particles will be produced after the explosion of the nuclear warhead, and these charged particles will disturb the earth's magnetic field. Many fragments produced by the nuclear explosion will especially affect the earth's atmosphere, and it is likely to bring many hidden dangers to the creatures living on the earth. sexual harm.

Moreover, a large number of alpha rays, beta rays, gamma rays, neutrons, and electromagnetic interference produced by detonating nuclear bombs in low earth orbit will cause great damage to the "Zero Satellite" and the "Zero Spaceship" that transports nuclear weapons to the sky. Impact.

This will cause satellites hanging in low earth orbit to fail at least, or to be damaged and fall.

Beyond that, Won also wanted to give viewers a glimpse into the true power of nuclear weapons.

So considering all things considered, he still chose to detonate such a nuclear bomb in the desert.

In the case of having enough uranium 235, it is not difficult for South Korean won to make a nuclear bomb.

Soon, a series of spare parts such as detonating devices, explosives, neutron reflectors, directional devices, and uranium columns were processed.

These things are not difficult to process for him who already owns various industrial equipment. Drawings, data models, and related NC programs are all in his mind, and he can copy them and write them into the central computer.

The audience in the live broadcast room watched the nuclear bomb being assembled, and expressed their views on the barrage.

[I said that the anchor is the most useless teacher I have ever seen. I didn't learn anything to teach, and it was useless if I learned it. 】

[Everyone is welcome to watch the following programs: "Atomic Bomb From Beginning to Mastery", "From Hanging out with Fish to Imprisonment! "" A little trick for going to prison every day! "】

[It feels so easy to watch the anchor make a nuclear bomb. If there are raw materials, I want to try it too. If I make it, I will sell it on the street. 】

[Emotions, you are the little girl who sells nuclear bombs. 】

[Manufacturing a nuclear bomb requires a lot of centrifuges and electricity, so the general country will be found by a big country, to be precise, by the United States, and then sanctioned, but now with the technology of the anchor, it seems that electricity and centrifuges are no longer needed , Maybe every country will have nuclear bombs in the future. 】

[It’s boring to watch, let’s talk about the details, for example, what are these parts used for? 】

[True punishment upstairs! 】

【Which boy doesn't want a boy? _]

[We don’t allow hydrogen bombs to be released during Chinese New Year, we can only use atomic bombs, the power is much smaller, and there is no new year flavor. 】

[It's okay, hydrogen bombs are banned, and it's a good experience to occasionally release antimatter bombs. 】

[You guys are still better, we only listen to the stick of God ╰(￣ω￣o)】

[A group of gods, but I also want to hear the details, although I know that uranium 235 can make nuclear bombs. 】

Looking at the playful barrage, Han Yuan smiled and said, "Then just say it briefly."

"In an atomic bomb based on uranium 235, there are mainly several main parts such as detonating device, detonating explosive, neutron reflector, uranium 235, shell case, and guide groove."

"Except for the neutron reflector and uranium-235, these parts are not much different from those used in ordinary missiles."

"It is also very simple to manufacture, a slightly more troublesome neutron reflector."

"The so-called neutron reflector refers to a cladding layer at the center of a nuclear bomb that prevents neutrons from leaking out."

"This layer is made of materials such as beryllium, graphite, and uranium-238."

"Its main purpose is to reflect neutrons."

"During the nuclear reaction, the neutron reflective layer can reflect the neutrons released by the nuclear charge in the reaction and may be leaked back to the reaction area, so that it can participate in the nuclear reaction to improve the reaction efficiency, so that the critical mass of the nuclear charge can be reduced. Significantly reduced."

"So this layer of structure is one of the core components of a nuclear bomb explosion. Its existence is related to whether the nuclear bomb can be detonated smoothly."

"The principle of the atomic bomb is actually very simple. The uranium atom splits, releases energy and releases neutrons at the same time, and the neutrons hit the uranium nucleus respectively, releasing energy and neutrons again."

"By analogy, it's what's called a chain reaction."

"But there's a problem here."

After a pause, Han Yuan continued:
"It is said in middle school textbooks that if a uranium-235 atom is compared to a football field, then the nucleus in the atom is only the size of a sesame seed, and the size of a neutron is smaller than a grain of dust."

"In such a vast space of atoms, it is conceivable how difficult it is for such a 'neutron dust' to hit the 'sesame nucleus' in a football field."

"The probability of one hit may not be higher than one in a billion."

"If the neutrons couldn't hit the nucleus, the chain reaction wouldn't happen, and the uranium-235 wouldn't explode at all."

"So in a nuclear bomb, if the chain reaction goes smoothly is the key factor in detonating the nuclear bomb."

"There are two solutions."

"The first is to arrange footballs with enough steps so that they are closely packed so that the 'neutron dust' goes all the way, and there is always a 'nuclear sesame' that gets hit."

"This is actually the critical mass of uranium-235 itself."

"Less than the critical mass means that there are not enough football fields. Most of the neutrons will fly out of the uranium block without hitting the nucleus. The reaction cannot be multiplied, and the uranium block will only heat up and not explode."

"When the mass is greater than the critical mass, the dust will continue to hit the sesame seeds, and the energy will multiply rapidly, resulting in a nuclear explosion."

"The critical mass of uranium-235 is 48 kilograms."

"If you can extract enough uranium-235, remember not to pile them all together."

"If the mass of uranium 235 piled together exceeds 48KG, you will experience a violent nuclear reaction."

"After I extracted enough uranium 235 before, I divided it into small pieces and stored them separately, just to prevent the chain reaction of uranium 235 from exceeding the critical mass."

"The other way is to create enough neutrons or trap neutrons."

"The neutron reflector is what traps neutrons."

"It is wrapped in uranium 235 and fully covered. In this way, even if neutrons do not hit any neutrons in the process of passing through uranium 235, they will be reflected back by the outer neutron reflector and re- into the uranium-235."

"This process is like playing billiards. A neutron is a billiard ball with almost infinite kinetic energy. As long as the billiard ball (neutron) does not fall into the pocket (reacts with the nucleus), it will continue to move on the court until it finally hits Other billiard balls on the table or pockets."

Hearing this, the live broadcast room suddenly became lively.

[That is to say, I only need to extract enough uranium 235, and then put it together to explode by itself? 】

[It can be said like this, but the premise is that you have enough uranium, and this mode should not explode, or the power of the explosion is very small, and it will only release a lot of radiation. 】

[I remember that there used to be a story in a textbook about a scientist breaking apart an atomic bomb with his bare hands. What was it called? 】

[Dr. Sroda, a famous physicist in Maple Leaf Country, did not break apart the atomic bomb, but separated two pieces of uranium that were being used for experiments. However, he was also subjected to a high dose of lethal radiation, and died in less than ten days. died. 】

[So, scientists told us that it is a wrong operation to break apart the atomic bomb with bare hands, everyone should not learn φ(*￣0￣)]

[You tm broke my atomic bomb, right? 】

[Don't make trouble, this incident was actually fired up, and the current textbooks have deleted this story. In fact, it was Sroda who committed suicide by operating illegally and then wanted to remedy it. 】

[It seems that a scientist was drinking coffee during the experiment, and the cup fell on the ground, which surprised Sroda, and the screwdriver slipped out with a flick of his hand. 】

[Others: Sliding and hitting their head while playing games, Scientists: Sliding and blowing up while playing atomic bombs. 】

[The incident of dedicating to scientific research is not a joke!In any case, scientists are worth learning. 】

[Are you kidding me?Learn a P!Do you understand the truth of the matter?What can a scientist like Sroda learn from a scientist who didn't follow the rules in the laboratory to save trouble and eventually caused a catastrophe? 】

[Each of the safety regulations is followed by human life.All lessons learned in blood. 】

Looking at the barrage, Han Yuan shook his head.

He naturally knew the story about breaking the nuclear bomb with his bare hands. This thing was still in the textbook when he was in school.

It's just that he doesn't know the details of this matter very well.

However, he can be sure that even if the two half-uranium used in the experiment were not broken apart, the experiment would not explode.

If such a simple collision triggers a nuclear explosion, wouldn't it be superfluous for scientists to develop explosives, detonators and other things.

So the supercritical mass of uranium he said before will produce a nuclear reaction, not a nuclear explosion.

In fact, this is also the case. Uranium 235 will automatically undergo a chain fission reaction when it exceeds the critical mass, but under normal circumstances, it will melt due to high temperature, which will eventually cause volume expansion and stop the chain reaction.

However, in this process, it is certain that the uranium block will release a large amount of nuclear radiation.

As for the range, it depends on the mass of uranium used.

However, this range generally does not exceed 20 meters.

The reason why the radiation range of the atomic bomb exceeds tens of kilometers is because of the strong impact of the explosion.

Therefore, if the scientists who conducted the experiment did not lift the lead pot cover protecting the hemisphere at the first moment of contact with the uranium hemisphere, but ran directly, if they came out of the laboratory afterward, they would all survive.

It was because Sloda lifted the protective lead pot lid that he died of an overdose of nuclear radiation, and other scientists also received some radiation.

However, this kind of thing can be said to be excusable at the time when Slorda made such a decision.

After all, the development of science is slowly groping.

At that time, scientists had calculated the critical mass of uranium 235, and knew that a nuclear reaction would occur if the critical mass was exceeded, but they did not know that the nuclear reaction would not explode.

So at that time, people believed that as long as the supercritical mass would cause a nuclear explosion, in order to prevent the nuclear explosion of the uranium hemispheres in contact with each other and cause greater harm, Sloda opened the protective cover and broke the two pieces of uranium with his bare hands. hemisphere.

This is caused by the limitations of the times, but this kind of courage is worthy of everyone's admiration.
