Chapter 42 (2/2)
Generally, the enrichment of uranium for civilian grade nuclear fuel is about 3%, while that for weapon grade nuclear fuel is more than 93%.
Naturally, the purity of this drop of uranium purified by Nie Yun can not be 100%, but some other elements are specially incorporated into it, and the purity is about 90%.
The conditions for nuclear fission explosion are critical pressure, critical mass and critical temperature.
The higher the purity of uranium, the lower the critical condition.
In other words, if it is 100% pure uranium, maybe tens of grams of uranium will be directly fission reaction at room temperature and pressure, leading to nuclear explosion!
Nie Yun naturally did not dare to really go to death, the concentration of 90% is his dog's gall.
Although the process of purification was very smooth, because the content of uranium in seawater was too low, even though Nie Yun added ten sets of piston extractors to work together, it took three hours and exhausted the reserve energy in the base, thus extracting a kilogram of 90% uranium.
Looking at the high strength of the glass made by Nie Yun?
He had a dreamy feeling.
Because the half-life of uranium is very long, the radiation under natural conditions is very weak, only when it is in fission state, it will emit a large number of lethal high-energy radiation rays.
Therefore, even if highly enriched uranium has little impact on human body, even if Nie Yun only uses a thick alloy thermos cup as a container, he does not have to worry about radiation damage.
As for why the thermos cup is used Can you expect Nie Yun to have a professional nuclear fuel container? I can only live with it!
Although the nuclear fuel is extracted, but he looked at the thermos cup in his hands but a little confused.
My goal is to build a nuclear powered hyena, but only nuclear fuel has no egg use.
He can easily build an atomic bomb now, but it doesn't mean he can build a nuclear power generator.
It requires much more technology than simply detonating an atomic bomb if the violent fission reaction is to be carried out continuously and stably to provide continuous energy.
Only a few countries in the world have mastered the technology of nuclear power plant, not to mention the miniaturized nuclear power ships. But this thing is an absolute state secret, Nie Yun also can't go online to download information!
Now Nie Yun is embarrassed.
He's the most dangerous person in the history of the world He will not be here!
”Didi!” Just then, Nie Yun's satellite phone rang.
This phone has been simplified by him, and now it looks smaller. He will directly cancel the battery parts that take up a lot of volume, because the robot worm can charge and discharge itself, so there is no need to keep the ugly large battery.
Regardless of the other capabilities of the robot, as a material, it has already exploded all the special alloys known on the earth, and it also has its own energy.
”Hello, Xiaoxiao!” Nie Yun did not look at the caller ID, in addition to Chu Xiaoxiao, no one knows the number.
”Nie Yun, thank you for saving me again. Sister Ye min asked me to thank you on her behalf!”
”Hey, what a big deal! Don't mention it. Next time someone ties you up, call me directly! ”
Chu Xiaoxiao:
”Where are you now? What do you do? ” Chu Xiaoxiao wisely didn't take his words.
”What can I do to fish?”
“…… You bought a freighter that big just to catch fish? ”
Chengjiang? You don't know, it has already become the dust of history, I will remember it
”Well, in fact, I don't know what to do with it. I can only fish!” Nie Yun perfunctory way.
”Didn't you think about shipping? This is a big profit, and our group has a lot of business. If you agree, we can cooperate. Of course, don't get me wrong. I'm not helping you!
Our group is doing ocean trade recently. We really need some reliable transportation companies to help with logistics.
What's more, each of your gold coins has been shot for about 3 million yuan. Now that you are a billionaire, you can consider opening a transportation company! It doesn't matter if you don't understand the process. We have related business in our group. I can help you with it! ”
Nie Yun scratched his head. He didn't understand Miss Chu's kindness. He got close to Chu's group. He was on the verge of success.
But logistics? He's really not interested.Brother, it's hundreds of millions every minute! I don't want to bend down to pick up gold coins everywhere!
A billionaire? For a nuclear fisherman, ha ha
However, he suddenly thought of a business that could be done.
”I really have a little idea. Don't you know that your group does import?”
”Yes, we do both import and export, and recently our business is inclining in this direction! There are a group of bad guys who do this, we are competing with them, hum! I must let them know that the Chu family is not easy to offend! ”
Nie Yun faintly guessed who the villain in her mouth was, but he didn't tell the truth. Instead, he laughed with a smile.
”That's great. I have some goods imported from other countries. I want to import them into China.”
”Well? What kind of goods? ” Chu Xiaoxiao asked suspiciously. How come you haven't seen you for two or three days, and you've started international trade?
”But you can rest assured that our business covers all aspects. As long as your products have a market, we can guarantee to introduce them to China for sale.” Chu Xiaoxiao is confident in her marketing ability.
”The market? Well, there should be That, cough! Do you want nuclear fuel? ”
