The Literary Life of a Science Leader

Chapter 111 The Atomic Bomb Manufacturing Method

In fact, this kind of key secrecy is very common.

For example, how to make an atomic bomb!
The early atomic bombs, the two atomic bombs dropped on RB Hiroshima and Nagasaki, were actually very primitive.

The Little Boy atomic bomb dropped on Hiroshima is a gun-type atomic bomb. The internal parts look like a gun chamber, mainly including electronic detonators, explosive packs, hollow shaft blocks, tungsten carbide and uranium blocks.

When activated, the electronic detonator at the tail will detonate the explosive package, and the expanding gas will push a hollow cylindrical uranium block into another cylindrical uranium block at the head, and the combination of the two blocks will exceed the critical mass.

What is critical mass?

The critical mass is the minimum mass of uranium material just enough to sustain the chain reaction.

根据美国核武器研究基地洛斯阿拉莫斯实验室于1969年的解密文件可知，93.8%的纯度的球形铀-235，密度为18.75g/cm3时，临界质量为52kg。

When the two uranium blocks are combined, they will also hit the projectile balls made of polonium and beryllium metal around the solid uranium block. These projectile balls can release a large number of neutrons and cause nuclear fission.

In addition, the uranium block is surrounded by thick tungsten carbide, which can reflect the leaked neutrons back to the uranium block, accelerate the chain reaction, and trigger a nuclear explosion.

The Fat Man atomic bomb in Nagasaki is an implosion-style wrapping structure that explodes from the outside in.

When activated, the electronic detonator will detonate a total of 32 explosive packages under the metal plate at the same time, and the shock wave will squeeze a spherical pusher made of easily deformable aluminum into the inner layer.

Eventually the nuclear material, plutonium-239, is constantly extruded into the center.A substance that is more fissile than uranium-235.

Due to extrusion, the density of this piece of plutonium-239 will increase rapidly and reach a critical state.The polonium-beryllium pellets wrapped inside will release a large number of neutrons, causing nuclear fission.

There is also a layer of uranium-238 on the outside, which is used to reflect neutrons and accelerate the chain reaction to trigger a nuclear explosion.

In this way, do you think it is not difficult to make an atomic bomb?

As long as the nuclear materials are in place, everyone can make it?
but it is not the truth.

There is nothing wrong with the fact that the construction of the atomic bomb does have guns and implosions, but that doesn't mean it's right.There are traps in the atomic bomb-related documents declassified by the United States.

First, the declassified materials deliberately overstated the enrichment of available nuclear materials and the critical mass of nuclear materials with different concentrations, so that if the materials were copied for testing, it would waste a lot of time to enrich the nuclear materials and lead to criticality accidents in the assembly of nuclear bombs. Possibly, increased risk of nuclear program exposure, and experimenter casualties.

Second, detailed information will give the leadership of the forces the illusion that nuclear bombs are not difficult, and errors in key data will lead to delays in the progress of nuclear tests. However, when the progress of the nuclear program is lower than expected, the research team will suffer greatly. Political pressure, even the team was dismissed, resulting in serious waste of scientific research.

Third, for countries that are conducting nuclear programs, if they do not conduct tests according to the data of the United States, the data will not only be of no help, but will also lead to a split in the opinions of the planning decision-makers and research teams. , or to copy the technical route of the United States to start a debate.

For the leadership, in order to ensure the smooth progress of the nuclear program, even if they knew that the materials might be fake, they had to detach a group of scientific researchers to follow up on the U.S. technical route, which led to duplication of research.

Fourth, for hostile countries that have mastered nuclear technology, even if they know the loopholes in the materials, they will not point them out. However, the partial authenticity of the materials will arouse their vigilance against vassal states, potential rivals, and other neutral countries researching nuclear weapons, prompting them to research nuclear weapons. The country's decision-makers carried out intelligence collection against these countries, which resulted in the country's intelligence forces being dispersed. At the same time, they would avoid nuclear proliferation and had to cooperate with the United States.

This is a common tactic in modern international politics, an open conspiracy.

Back then, the U.S. released some hydrogen bomb data, trying to mislead China's hydrogen bomb research and development. Once it fell into the pit, it would waste a lot of resources. Fortunately, Yu Min immediately noticed that there was a problem with the data, and then determined through calculations that it was wrong.

Of course, in this era, even if we know how to make an atomic bomb, there is no source of nuclear materials.

Uranium mines around the world are controlled by the five gangsters. Only countries that have signed the nuclear non-proliferation agreement can buy low-enriched uranium for power generation from the five gangsters.

Moreover, the disposal of nuclear waste must be reported, but India’s leader refuses to sign it, so India’s nuclear power plants have not been able to develop.

Pulling away again, back to the topic.

Mu Jingchi's key secrecy is like deciphering the method of making an atomic bomb.

Actively expose some content and attract material researchers to conduct research together, but the most critical data and precise path have always been kept in their own hands.

On the one hand, it can guide foreign materials research, and finally make wedding dresses for Mujingchi and Huaxia.On the other hand, it is to extend this 'dislocation theory system' to a larger scale, which is very important for future material research.

This debate is definitely fruitless, at least not at this meeting.

Whether or not to keep it secret, and how to keep it secret, are not the topics that researchers like them care about. It is enough to express their own ideas. As for how to do it at the national level, it is beyond their consideration.

Regardless of whether it is kept secret or not, there is no doubt that this dislocation system that links theory and application will continue to be studied.

So, Minister Huang started the next topic.

"Led by the School of Materials, Huaqing University, in conjunction with the School of Mechanical Engineering, and the [-], [-], and [-] Research Institutes of the Ministry of Industry and Information Technology, the core project of the research topic 'Mujingchi Dislocation Theory System' is jointly formed."

"Dr. Mu Jingchi, School of Materials Science and Technology, Huaqing University, as the academic leader of this core project, is responsible for the construction and guidance of the general direction of theory."

"Do you guys have any ideas?"

The next thing involved real material research. Minister Huang and Minister Xie began to read the relevant red-headed documents.

Young people may not be stable or experienced, but young people are aggressive, aggressive, imaginative, and unconstrained.

Besides, Mu Jingchi is not alone, behind him is the extreme condition material team headed by Yang Wenwu, and also supported by Harbin Institute of Technology, one of the seven national defense leaders headed by Zhou Huaiguo and Du Cunyi.

This is not the power of a single person, it can also be said to be the power of academic schools.

Therefore, such a heavy responsibility fell on Mu Jingchi.

The professors and academicians below glanced at Mu Jingchi, and most of them shook their heads slightly.Mu Jingchi was born in Huaqing University, behind him there is a huge school of materials, and Huaqing University's network strength is also top-notch.

There is really no way to compete for this kind of academic leader who is almost the core project topic of Huaqing University's bowl of meat.Even if it is to talk about qualifications, it is not up to people outside the School of Materials Science and Technology of Huaqing University.

Fortunately there are other projects out there.

Through Mu Jingchi's academic report in the morning, they knew that Mu Jingchi had a total of [-] core conjectures for the entire dislocation theory system.

But this is just a guess. Who can guarantee that this must be the correct path?

Everything is possible before it becomes a real system.

In their hearts, perhaps the direction they choose is the real core direction.

　The two updates are over today, please recommend a ticket.
