"It seems that the plutonium-239 plan proposed by the Führer Cyric back then is really a shortcut!" Heisenberg said to Hahn while walking.

In the selection of nuclear weapons, Cyrek first made a plan for plutonium-239. At that time, it didn't seem to have a lot of feelings, but now I have realized Cyrek's wisdom.

Compared with direct combustion to obtain plutonium, the centrifuge method is really too expensive!

How expensive is it? The nearby power station is almost enough for all people in Germany. Now, just supplying these centrifuges is just right! The country's electricity is consumed to enrich the nuclear materials. This is also the reason why few countries in later generations can cross the nuclear threshold.

If it is used as a raw material for a nuclear reactor, it only needs to be enriched to 50 or 60%. Therefore, some countries can obtain the raw material for nuclear reactors. However, nuclear weapons must be enriched to 99%, which is almost It is all uranium-235, and the difficulty of this is increasing exponentially.

It is conservatively estimated that relying on our own centrifuges, it will take at least two years of work to have the raw materials to build a nuclear weapon.

While communicating, the two walked out of the underground centrifuge separation factory here.

"Yes, our current plutonium-239 has been produced in enough quantities. Now, our last problem is to determine the critical mass."

Hahn said.

This is a professional content. The inside of the atom is quite empty. If the nucleus is compared to a football, the space of the atom is definitely much larger than the entire football field.

Fission occurs under the impact of neutrons. At the same time, there will be neutrons among the products of impact. Moreover, one fission will generate three or four neutrons, which means that once the fission starts, It can proceed spontaneously, because the neutrons of the product will hit other atomic nuclei and continue to induce nuclear reactions.

In this way, a neutron hits an atomic nucleus to form a fission reaction, releasing four neutrons, and four neutrons hitting another four nuclei to generate four nuclear reactions, which will produce sixteen neutrons, so it increases exponentially In a short period of time, a large number of atomic nuclei are fissioned, and huge energy is released.

This is the atomic bomb.

However, the inside of the atom is quite empty. If the size of the atom is not large enough, there will be a result. The neutron has not hit the nucleus, and as a result, it will fly out of it.

The volume of the entire nuclear material that can continue to react is called the critical volume, and the corresponding mass is called the critical mass.

This thing cannot be calculated through theoretical calculations and must be measured in experiments.

Heisenberg nodded: "Yes, the critical mass measurement is urgent. Have you found someone?"

There is no doubt that this kind of test is quite dangerous, and the candidates for the test must also be cautious.

Hahn nodded: "We have selected seven people from the volunteers to form a measurement team. Among them, the operator is assumed by Slotin. His response is the fastest, and he also has excellent psychological qualities."

Heisenberg carefully accepted the information handed over by Hahn. At the top is the code name of the entire test item, scratching the tail of the evil dragon.

The name alone is enough to reflect the danger of this project, just like scratching the tail of the evil dragon. Once the evil dragon is angered, a slap will slap you to death.

Slotin, given his nickname, is a superman.

Repeated death, repeated death, so he won such a title.

Slotin, a Canadian, is the champion of amateur boxing at school. Before finishing college, he took the friendship of revolutionary comrades and traveled all the way to Spain and participated in the Spanish Civil War. As a result, like George Orwell, he saw the ideal he was pursuing, which was simply ridiculous. Up.

All animals are equal, but some animals are more equal. This is definitely the best irony. The fruits of the revolution were ultimately usurped.

Slotin realized that he, like Orwell and others, was captured in the final battle, and then began a new life in Germany.

He quickly integrated into his new life. He had a great time in Germany. He became a test pilot for the Henschel Company in Germany. He had a great time. All dangerous subjects would fall at any time. The dead subjects were all tested by him.

Therefore, he also gained the trust of Germany. If he is a spy, there is no need to risk so many deaths and engage in intelligence. After all, it depends on the cost.

He has experienced the risk of death. In the test flight alone, there were more than 20 times, every time he turned the danger into a breeze. Therefore, he finally won the title of a dead superman, and he was extremely satisfied with this title.

He likes to explore. Just before coming to the secret base, he planned to climb the Alps with his bare hands. As a result, after layers of selection, two years ago, he was absorbed in and participated in this top-secret project in Germany.

Slotin’s resume was in Heisenberg’s hands. Heisenberg saw the last page and said: “Let him try it~www.novelhall.com~ If the experiment is successfully completed, I will give him Strive for the honorary title of the Holy Aryan."

Base, central area.

The entire nuclear program is too large, so, like the Manhattan Project in the United States, it is divided into two areas, inside and outside, with different levels of confidentiality. Some technicians on the outside do not know what projects they are working on.

For example, a power station thinks that I am just a technician of the power plant.

Internally, I only know one aspect of what I am in charge of, but I don't know everything.

If there is a traitor, then only one detail is known at most. The only people in charge of the entire project are Heisenberg and Hahn.

Slotin is very interested in this task. After intensive preparations in a laboratory in the central area, the experiment is about to begin.

"This is the core of the devil." Slotin looked at the experimental device in front of him, and a flame of love appeared in his eyes. For him, this thing was too magical!

In front of him, there are two hemispheres, these two hemispheres, the outside is made of beryllium, and its inside contains the core of plutonium. There are also two halves, respectively inlaid on the two outer hemispheres.

If you compare it, it is like an egg, cut in half, the outer beryllium is the egg skin, and the inner plutonium is the egg yolk.

The plutonium inside is all that has been burned out of the nuclear reactor so far, which is 6.2 kg! Now, it is used to carry out a series of nuclear tests. If it is installed directly according to the design plan, it may be directly an atomic bomb.

In fact, the steps of the experiment are very simple. Gradually approach and approach the two hemispheres, insert a screwdriver in, pry apart, and insert shims of different specifications to find the distance between them. For the superman, this It's very relaxing. 8) For more wonderful novels, welcome to visit everyone's reading academy
