Chapter 1883: Changing the subject

Previous page        Return to Catalog        Next page

    Nuclear weapons are the topic of most interest to Americans.  But that also means this thing is sensitive.  Americans want to manufacture nuclear weapons by themselves, and at the same time they will be on guard against other people's manufacture of nuclear weapons. If the Eighth Route Army has talents in this field, I am afraid it will attract their special attention.  Qin Baoshan didn't want to cause trouble for Wei Shuqin, so he simply changed the subject.

    How to make a nuclear bomb was originally very difficult.  The Germans didn't make them until the end of the war.  Although the United States was created, it also gathered the strength of the whole United States and gathered the most intelligent people in the world.  Don't even think about the Eighth Route Army here, so Americans don't have to be wary of the Eighth Route Army.

    Of course, this possibility was originally very small.  After all, China is a backward country with almost zero scientific research.  In such a country, no one believes that an atomic bomb can be built.  In this age of war, it is even more impossible.

    Regarding the topic of the atomic bomb, Qin Baoshan didn't want to talk more with the other party. If he said too much, it would mean that the Eighth Route Army had indeed studied this aspect, so he simply changed the topic from nuclear weapons to nuclear reactors.  , the effect is completely different.

    When nuclear reactors were first manufactured, they were actually used for military purposes, for submarines.  With nuclear reactors, submarines have unlimited endurance and become famous ocean killers.  Not enough, the subsequent nuclear reactors began to be used for civilian purposes.  In some countries, even the main domestic electricity is supplied by nuclear power.  If there were not several nuclear accidents, then nuclear power will definitely become the clean energy of mankind in the future.

    Now these American experts are concentrating on making nuclear weapons, and have never thought of using this kind of thing to generate electricity.  So now a new door has been opened for them.  Since Rosen came here, he must gain something.  Provide him with some knowledge about these nuclear reactors, and he will be satisfied.

    And Qin Baoshan also knows that due to the shadow of war, many scientists have to unite in the United States to manufacture nuclear bombs together.  But when the war is over and they see the terrible power of nuclear weapons, they will have a deep worry, and they have opened Pandora's box with their own hands.  They just want to end the war, but their invention may bring disaster to all mankind.  In this complex mood, many people who originally developed nuclear weapons have changed their direction and used their research to benefit mankind, that is, to build nuclear power plants and provide energy for mankind.

    The Luo Sen in front of him is one of them, so Qin Baoshan handed over this thing to him in advance, which can be regarded as paving the way for his future scientific research.  In this way, there will be a closer relationship. In the future, if it is inconvenient for Mr. Qian and others to come back from the United States, they may be able to ask this Rosen for help. This will be considered as a pavement for the future.

    Qin Baoshan had various considerations.  Now, Wei Shuqin said that using this thing to serve mankind, as an expert, of course, Rosen immediately understood what Wei Shuqin was talking about.  A gleam of hope flashed before his eyes.  If the energy contained in these atomic nuclei is released all of a sudden, it will explode.  If it is released gently, it can be used as energy smoothly.

    Scientists like them don't want to develop any bombs, and this nuclear reactor is even more attractive.  What surprised Luo Sen even more was that Wei Shuqin actually took out a design drawing while talking.

    "This drawing was drawn by myself. The original drawing was designed by our teacher. I drew a new one based on memory." Wei Shuqin said.

    The drawing was spread out, it was a model of a nuclear reactor.  This is the schematic diagram of the oldest graphite reactor drawn by Qin Baoshan based on his high school physics knowledge in another time and space.  This is the kind of nuclear power plant that exploded at the Chernobyl nuclear power plant.

    The main body of the entire nuclear reactor is piled up with graphite blocks.  Pieces of graphite are stacked like bricks on a construction site.  This graphite is the main body of the entire reactor.  In addition to being used to prop up the reactor, its more important task is to be used as a moderator.  In order to cause fission of uranium nuclei, only slow neutrons can easily break open the nucleus, resulting in nuclear fission, and the neutrons generated by the reaction are all fast neutrons, so in this process, there needs to be a deceleration process.  Using graphite as a moderator is a graphite reactor, and using heavy water as a moderator is a heavy water reactor.

    Now, this schematic drawing is very vivid, and there is even a part of it as a cross-sectional view. In addition to seeing the graphite stacked up, you can also see the rods inserted in the center of the graphite block.  Inserted vertically is the uranium rod, which is the burning nuclear material.  if nuclear weapons, then the raw material must be concentrated to more than 99%.  But if it's a nuclear power plant, 40 to 50 percent is enough, so it's easier.

    The one inserted horizontally is the control rod.  The control rods are made of cadmium, which has a particularly strong neutron-absorbing ability.  If there are too many stuffed in, more neutrons will be absorbed, and less neutrons will participate in the reaction, so the nuclear reactor will run at low power. If all the neutrons are inserted, the nuclear reactor will stop.

    As for the result of the reaction, it is of course heat, which is taken away by the circulating water flowing past.  The water can be directly turned into steam to drive the steam engine, or it can continue to be used as the heating agent of the boiler to heat another set of boilers.  In this way, although there is one more cycle, the nuclear radiation material will be controlled in the first cycle, which is very safe.

    After reading the drawing and listening to Wei Shuqin's narration, Rosen's whole body trembled.  He said to Wei Shuqin: "This is really a great genius idea. We can use the energy in the atomic nucleus to serve human beings. Your teacher is really great. I will consult with the Chongqing government and I must send you  The teacher found him, and I will take him to the United States."

    As soon as these words came out, Qin Baoshan's heart skipped a beat again.  In front of this person, why do I always do things before?  This time it was like this again, a myth of a non-existent teacher.  If this Lawson confronts the Chongqing government, he will soon find out that there is no such a teacher, nor a student like Wei Shuqin.
