Chapter 350: Nuclear power plants are capable of producing nuclear bomb materials

Originally, when I said yesterday, I was going to visit the breeder reactor, which is used to produce weapon-grade nuclear materials, but now, because there are people from the Han country who are visiting together, the chicken country has converged a little, and I brought everyone here. The ordinary Macur nuclear power plant.
This is the earliest nuclear power plant in the country. At the beginning, the first nuclear reactor was put into operation in Markur in 56 years. At the same time, in 68 years, the nuclear power plant was decommissioned.
Later, in 59 and 60 years, two other nuclear reactors were established, and these two nuclear reactors, historically, in 1980 and 1984, have also been out of operation.
This is the first-generation nuclear reactor that uses graphite as a moderator.
The energy of the nucleus comes from the loss of mass, and the loss of mass is due to the splitting of the nucleus under the impact of neutrons. However, only slow neutrons can easily collide, and the effect of fast neutrons is very poor. (Speed ​​refers to speed)
Therefore, it is necessary to turn fast neutrons into slow neutrons, which is the function of moderators.
Back then, during World War II, Hans State was developing nuclear reactors, but at that time they all thought that heavy water could be used as a moderator, and Niu State sent people to blow up Hans State's heavy water factory and prevented them from producing.
In fact, Hans State at that time did not know that in addition to heavy water, the most common graphite can be used as a moderator, and most of the first-generation nuclear reactors use graphite as a moderator.
The first generation of nuclear reactors developed by Ji Country was a graphite gas-cooled reactor, and the second generation was a pressurized water reactor.
Now, these first-generation nuclear reactors are almost about to be shut down, so even if people from Han are invited to visit, there will be no major problems. At the same time, people from the date palm country are even more knowledgeable. Yes, I brought them here, mainly because I want to urge them, the nuclear reactor, can't we do it?
Now, as a representative, Morris took them into the control room of the nuclear power plant.
"What you can see is that we have been safely operating nuclear power plants for 20 years. The nuclear power technology of our country is quite reliable, effective and safe. We are also willing to export our nuclear power technology to any energy shortage. Country," Morris said.
Does Han State lack energy? It may not be lacking now. Han is still an oil exporter. However, Han has already begun reform and opening up. This is a country with a huge population. Once developed, the demand for energy will be quite large, so Although Morris is the chief of staff of the Air Force, it is said that he can't reach it, but he is also doing his best to serve the interests of the chicken country.
If you say that the Han country comes to the chicken country to import nuclear reactors, you can make another profit.
Safety? Qin Guan couldn't help but laugh when he heard Morris said that it was safe. Others didn't know, but he knew it. The most unsafe is graphite reactors. The nuclear reactors here are all graphite reactors.
Why is it called heap? Because graphite is piled up piece by piece, it is similar to a pile of bricks. This is the name of the reactor. Graphite can be used as a moderator, but it is not easy to dissipate heat. Therefore, the melting of the core is all graphite. The reactor dried out.
"This kind of nuclear power technology is exported for civilian purposes. At the same time, it can also export the raw materials for nuclear weapons." Qin Guan said with a smile: "In this type of nuclear reactor, the plutonium needed for nuclear bombs can be produced."
Hearing this, the people of the Date Palm Country suddenly changed their expressions, and Qin Guan said nothing.
There are two kinds of raw materials for nuclear bombs, uranium 235 and plutonium 239.
Among them, the content of uranium-235 in natural uranium ore is only 0.715%, and the remaining 99% is uranium-238 that cannot be used by fission. To make an atomic bomb, the content of pure uranium 235 must be as high as 93.5%.
This is quite difficult, because the two are isotopes and their chemical properties are exactly the same. It is impossible to distinguish the two by any chemical means. Only the slight difference in the specific gravity of the two can be used. Centrifugation is used to separate and refine. come out.
In this way, to extract 1 kg of pure uranium 235, at least 200 tons of high-quality natural uranium ore is required, and tens of thousands of centrifuges are required to rotate around the clock, consuming a lot of electricity and financial resources.
To be specific, look at the Parthian nation. It took more than 20 years to operate hundreds of thousands of centrifuges. Until later generations, only less than 10 kg of 235 uranium with a concentration of 20% was produced.
Therefore, it is quite difficult to build a nuclear bomb with uranium-235. In contrast, it is much simpler to build an atomic bomb with plutonium-239.
Plutonium 239 hardly exists in nature. It is obtained by bombarding uranium 238 with fast neutrons in a nuclear reactor.
Since plutonium-239 and uranium are two completely different elements, simple chemical methods can be used to extract and purify plutonium-239 from spent reactor fuel!
To get plutonium 239, only build a nuclear reactor to make it artificially.
Making plutonium bombs is much simpler than uranium bombs, and exporting nuclear reactors means exporting nuclear weapons raw materials to target countries!
Hearing what Qin Guan said, Morris shook his head: "Why then? We have always advocated the peaceful use of nuclear energy. The output of nuclear reactors must be supervised by the International Atomic Energy Organization, and we also have a whole set of nuclear waste disposal facilities. Technology. Now, I will take everyone to see how to deal with nuclear waste."
Nuclear power is for the benefit of mankind, but how to deal with radioactive contaminated nuclear waste is another problem.
The Macur nuclear power plant was the first to be established and has been in commercial operation for more than 20 years. At the same time, the first batch of nuclear reactors will soon be eliminated.
Therefore, Ji Country simply uses waste and has established nuclear waste treatment plants in these nuclear reactors.
Now, the first nuclear reactor has been discontinued, and several large furnaces have been built in its original location.
At this time, the snowflakes outside were still boiling underground, and the ground had begun to freeze. When he came out of the control room, looking at the silver-clad world outside, Amir controlled his surprise, but his eyes were exposed. Everything about him.
The other date palm countrymen who went with them all began to cheer.
"There are two nuclear waste processing furnaces over there." Looking at the buns from the tropics, so surprised by the snow, Morris said: "We can walk over, of course, if everyone wants, in the past At that time, you can roll up a snowball."
Walking on the snow, there is a crunching sound under your feet. If you have not experienced it, you will find it very interesting. At the same time, is also an activity that can only be found in the snow.
As for snowball fights? Forget it, adults are not good at playing this kind of game, and they are still people from many countries.
