Chapter 298: 4 years to build the atomic bomb

What Hitler wanted most to hear was that the nuclear bomb would be manufactured tomorrow. If it didn’t work, then next year would be okay. Now, the result given by Heisenberg is hundreds of years!
What's the joke, Hitler can't live for a hundred years, so what use is the investment now?
"Dr. Heisenberg, there must be some problem, right? Speaking out, our empire will use our best to solve it." Cyric said.
Of course Cyric was playing cover for Heisenberg. Heisenberg gave him a grateful look and continued: "Our nuclear reactor is just a small experimental reactor, and the burning speed is too slow."
"Then continue to build large nuclear reactors." Cyric continued: "Don't worry, the empire absolutely supports this plan, and funding is not a problem."
"General Cyrek, we can build larger nuclear reactors. The electricity generated in this way is sufficient for scientific research in daily life. However, our current problem is that we cannot buy enough uranium ore. If we are in the international market If you buy a large amount of uranium ore, it will arouse the vigilance of other scientists."
Germany has not yet discovered uranium ore. This ore is imported from outside. The best uranium ore in the world is Congo’s uranium ore! The largest uranium mine in Europe is located in the Czech Republic.
Now, after hearing Heisenberg’s words, Cyrenk shook his head:
Dr. Heisenberg, if it’s the uranium ore problem, then we can now start construction immediately and build a larger nuclear reactor. We can always start from the Czech Republic, Obtain enough uranium ore, although the quality is not as good as that of Congo, it is enough."
Get it from the Czech Republic anytime? Heisenberg reacted immediately: "We have already occupied the Czech Republic?"
The technicians present were excited, but Hitler nodded in satisfaction.
The scientists who arrived here in the latest issue also arrived half a year ago. They only know that the relationship with the Czech Republic is strained, but they do not know that the Czech Republic has been annexed. The confidentiality work here is really good.
Unlike the oil base, there are no radios here, and it is completely isolated from the world.
"Well, then we need to continue to allocate 500 million marks to build a larger nuclear reactor." Heisenberg said.
The construction of nuclear reactors is very resource intensive, especially in Libya, all materials need to be transported from Germany, which would cost even more.
Hearing 500 million marks, Hitler first frowned, and then agreed again. After all, if this kind of bomb can be made, it is definitely a big killer!
"With this new reactor, we can build an atomic bomb in a few years?" Hitler continued to ask.
For scientists, Hitler valued them very much. They were the precious wealth of the empire. Hitler had never put scientists in prison for research like Stalin did.
However, having consumed countless resources of the empire, Hitler would definitely not be satisfied if there were no results satisfactory to Hitler.
So Heisenberg remained silent again.
He needs Cyric to get out of the siege. In fact, while building nuclear reactors and continuously burning raw materials for nuclear weapons, they are also conducting theoretical research on nuclear weapons, but the results are shocking.
Seeing Heisenberg's silence, Cyric suddenly remembered the interesting scientific talks of later generations. In the development of the atomic bomb, Heisenberg has taken many detours, and now, it is up to him to break the final key!
"Great heads of state, everyone present, I think of a famous question called drunk walking." Cyric said: "A drunk who walks randomly on the square and turns back 80 times. How big will he stay? In the radius?"
Cyric’s words made Heisenberg a flash of hope in his eyes instantly. General Cyric is simply a god. What he is talking about now is a big problem he faces!
To produce a chain reaction, neutrons must hit the nucleus. This is a very small probability. The space inside the atom is empty. Then there is only one way to increase the quality of the reactants so that the reaction of a uranium nucleus can be guaranteed to occur at least 80 times!
In this case, a lot of volume is needed!
How old? Heisenberg calculated it several times, and the conclusion is that it is crumbled, 54 cm, which is equivalent to 13 tons of uranium 235, or similar plutonium 239, even if it is to build a huge nuclear reactor and want to produce so many reactions It is also very difficult to get things done, at least, it will not be possible for more than ten years.
Hitler was able to ask for a few years, he was already very patient.
Now, does Cyric have a solution?
"If no one interferes, then the drunkard’s radius of activity will be very large, but if someone interferes, the order of magnitude may be greatly reduced."
After that, Cyric’s eyes looked at Heisenberg: "Dr. Heisenberg, have you ever thought about it. You can cover the nuclear material with a neutron reflection layer to let all the neutrons generated by the reaction. Continue to reflect back and continue to participate in the fission reaction?"
The critical mass of a nuclear bomb is a very important data. Heisenberg calculated it to be an astonishing number of 13 tons. Even after Germany was defeated and the United States successfully dropped an atomic bomb on Hiroshima, Heisenberg did not believe it.
"I don't believe the news about the atomic bomb at all. Of course I might be wrong. I thought they (allies) might have 10 tons of rich uranium, but I didn't expect them to have 10 tons of pure uranium 235!"
Later, Heisenberg learned from the newspaper that the actual weight of the bomb was 200 kg ~ EbookFREE.me ~ The core explosive was only a few kg. He looked irritable, wondering where his estimate was wrong.
Now that Cyric has awakened him, he doesn't need so many at all. Use all the neutrons and add a reflection layer!
Just like a cool breeze in a hot afternoon, Heisenberg suddenly realized that he had found the right plan!
"Head of State, if we build a large reactor now, we can produce enough nuclear materials within two years!" Heisenberg said: "Then within two years, we will produce nuclear weapons!"
Within four years, this weapon will be completely manufactured! Heisenberg is now full of confidence.
It is now 38 years. Four years later, it will be 42 years. If the atomic bomb can be made in 42 years, then the entire history of World War II will definitely be rewritten!
Surrender or not? Grow you mushrooms without surrendering!
"Okay, then four years." Hitler said: "I hope we won't let us down. This is the secret weapon of the Empire! Next, let's talk about how the missile is going."
