There are three forms of nuclear reactions known to mankind, namely nuclear fission, nuclear fusion and nuclear decay.
Among them, nuclear fission and nuclear fusion can provide energy to humans. According to Einstein's mass-energy equation E=mc^2, it can be seen that as long as there is mass attenuation before and after the nuclear reaction, it means that a certain amount of energy is released.
The so-called nuclear fission produces energy by causing mass loss through the splitting of heavy atomic nuclei.
Nuclear fusion, on the other hand, is just the opposite. It produces energy through the aggregation of light atomic nuclei to produce heavier atomic nuclei, which undergo mass decay.
The reason why nuclear fusion is better than nuclear fission is not only because the energy released by nuclear fusion is greater, but more importantly, the raw materials for nuclear fusion can be extracted from seawater. Deuterium is abundant in the seawater of the earth, with up to 400,000 Billion tons, if all were used in fusion reactions, the energy released would be enough for human beings to use for tens of billions of years.
Uranium-235, a common reaction raw material for nuclear fission, has scarce reserves, and the nuclear waste produced will affect the geology for hundreds of years. Therefore, nuclear fission cannot be compared with nuclear fusion in terms of reserves or cleanliness and safety.
Therefore, nuclear fusion energy is an unlimited, clean, and safe new energy that countless people yearn for.
Of course, nuclear fusion does not only refer to the fusion of deuterium and tritium. As long as the elements in the periodic table are smaller than iron, nuclear fusion can actually occur. The reason why humans choose only tritium and deuterium as fusion materials is because they undergo nuclear fusion. The conditions are the simplest.
Compared with other elements, the hydrogen isotopes deuterium and tritium have only one proton in the nucleus. For the fusion reaction between tritium and deuterium, it is enough to overcome the repulsive force between two protons, while other elements need to overcome a bunch of protons. The previous repulsive force was extremely difficult.
Now that the next step to conquer nuclear fusion was determined, Chen Chen returned to his office and found out the nuclear fusion reactor technology in the "Elysium Space" plane.
But after a few glances, Chen Chen frowned. He had always specialized in medicine and biology. Although he had a slight understanding of nuclear physics, it was only superficial. At most, he only knew more than ordinary people.
So, Chen Chen raised his head and said, "X, immediately compile a document for me that can quickly understand nuclear physics."
As he spoke, he took out an iron box of chewing gum, opened it gently, and immediately a piece of NZT-48 flew into his mouth.
Then Chen Chen's expression became clear.
At the same time, Little data of.
This time, Chen Chen could almost understand it.
"I didn't expect that there is more than one kind of nuclear fusion reactor technology used in the plane of "Elysium".
Chen Chen smiled and opened the second drawing, "Inertial confinement fusion reactor and magnetic confinement fusion reactor? It's incredible..."
"Actually, these are the two mainstreams in all continents of the Earth Federation."
Xiao X explained, "But if these technologies are broken down, they can be divided into multiple branches. There are even similar jokes circulating on the Internet..."
"What kind of joke?" Chen Chen couldn't help but ask.
"It divides various fusion branch technologies into the nine camps of DND at an intuitive level. Each camp also has an anthropomorphic speech."
Little
"As for the neutral and kind-hearted magnetic realm, the anthropomorphic statement is: there is no more magnetism worth leaking, and there is no more helium-3 to burn, because I no longer make reactors!"
"And the chaotic and kind-hearted Tokamak: Plasma Current, I tell you again, don't cause trouble again!"
"In addition, there are spherical tokamak that represents lawful neutrality, field anti-configuration constrained tokamak that represents absolute neutrality, and magnetized target fusion that represents chaotic neutrality, etc..."
The more he talked about it, the more excited Little
“…”
Chen Chen looked up in shock, "X, did I hear correctly? You are actually in GHS?"
"I, I don't have it..."
Little Smell!"
Chen Chen shook his head and did not care about this issue. He just kept in mind the changes in Little Many, in fact, it’s because the physical laws of the two reactions are different.”
"The nuclei of nuclear fission have a large mass and are inherently unstable, so fission reactions can be achieved as long as the environment is at normal temperature and pressure, but nuclear fusion is different. To overcome the huge electrostatic repulsion between nuclei, there is not enough energy or special If the environment breaks through the critical point of this repulsive force, it will be impossible to fuse the atomic nuclei together."
"So, the key is to create a high-pressure and high-temperature environment, right?"
"Yes, it is."
Little Fusing hydrogen atoms into helium atoms.”
"But if humans want to achieve the same nuclear fusion on earth, ultra-high pressure conditions are completely impossible to achieve. Therefore, humans' current nuclear fusion devices need to work hard on high temperatures and need to increase the core temperature from 1,500 degrees Celsius in the core of the sun. The temperature must be raised to over 100 million degrees."
"The simplest and most direct method is to use a large number of energized coils to form a ring along the ring, so that it can generate a strong magnetic field to form a magnetic confinement nuclear fusion reactor. This device that can generate a strong enough ring magnetic field is called Called the 'Tokmak Device'."
"Another type of inertial confinement nuclear fusion reactor is to put a mixture of deuterium and tritium in milligrams into a small ball with a diameter of several millimeters, and evenly inject a laser beam from the outside. The spherical surface will expand outward due to the absorption of energy. Evaporation, and due to its reaction, the gas in the ball is squeezed and the pressure rises, accompanied by a sharp increase in temperature. When the temperature reaches the required ignition temperature, the gas in the ball explodes and produces a large amount of Thermal energy!”
