Is the Sun light nuclear fusion or heavy nuclear fission?

The core temperature of the Sun is as high as 15 million degrees Celsius, and the pressure is equivalent to 250 billion atmospheres. The gas in the core is extremely compressed to 150 times the density of water. Nuclear fusion takes place here, and 700 million tons of hydrogen are converted into helium every second.

In the process, about five million tons of net energy are released.

The sun is engaged in nuclear fusion all its life, from the formation of the beginning of the light to the hydrogen fusion of the main sequence star, the late hydrogen combustion begins helium nuclear fusion, generally higher than the mass of the sun can carry out nuclear fusion with a larger atomic number in the late stage, all elements in the universe are produced through the nuclear fusion of stars.

At present, nuclear fusion cannot be fully controlled, and some nuclear fusion devices are in the experimental stage, and there is still some time before commercial use, so the current nuclear power plants are all nuclear fission type.

Sun former. Nuclear power plant the latter.

The former is more powerful, but human technology has not been able to use it smoothly.

The sun is nuclear fusion h+h=he. Nuclear power plants are fission, because humans have not been able to control nuclear fusion very well so far. So, a nuclear power plant should be nuclear fission.

The sun is made of hydrogen and helium. Nuclear fusion occurs between the two elements.

The artificial sun is nuclear fusion. The so-called "artificial sun" refers to the full use of this scientific principle to build a nuclear fusion device on the earth, which will occur like the sunNuclear fusion reactions, the limbs are accompanied by a continuous stream of energy. Strictly speaking, the name of the artificial sun is not exclusive to the Oriental Superring, and any device that applies a similar principle can be called so.

Nuclear fusion occurs in the sun, which relies primarily on the gravitational pull of the planet to confine the plasma. But there is not such a large gravitational force on the earth, and if you want to keep the energy from getting out of control, you need to use the magnetic field to constrain it. The realization of controlled thermonuclear fusion is inseparable from the extreme environment of ultra-high temperature, ultra-low temperature, ultra-strong magnetic field, ultra-high current, and ultra-high vacuum, scientists.

The tokamak is made of a magnetic field, which firmly controls the hot material, and the outside of the magnetic field is isolated by a vacuum to protect the material of the device from being burned.

Characteristics of nuclear fusion

Nuclear fusion has the potential to avoid the generation of long-cycle radioactive waste. This can be achieved with proper structural materials and coolant design, i.e., eliminating any long half-lives that can be excited.

Isotope material. One such design optimization is RAFM steel, which is a modified 91-gauge steel that is free of molybdenum and niobium.

Fusion reactors.

The use of such low-activation materials mainly leads to the generation of C-level low-level waste, which does not require deep geological treatment according to the definition of C, and will cause minimal harm to potential residents even if there are potential residents at the disposal site in the next 500 years. The use of these materials in future nuclear fusion reactors ensures that the equipment operates safely, while also being environmentally friendly and leaving no visible waste.

The sun is nuclear fusion.

The Sun uses the proton-proton cycle, one of the pathways by which four hydrogen nuclei fuse into a helium nucleus, a reaction process that is a small-mass, low-luminosity main-sequence star.

For example, more than 90% of the energy radiated by the Sun at this stage is provided by proton-proton reactions.

Nuclear fusion is also known as nuclear fusion, fusion reaction, fusion reaction.

or thermonuclear reactions, atomic nuclei.

There is a huge amount of energy in it, and the change of the nucleus (from one nucleus to another) is often accompanied by the release of energy.

The conditions under which nuclear fusion occurs

The conditions required to produce nuclear fusion are very demanding. The sun, for example, has a central temperature of 15 million degrees Celsius, and there is a huge amount of pressure to allow nuclear fusion to take place normally. And the earth can't get that much pressure, so it can only be compensated by raising the temperature, but then the temperature will have to reach hundreds of millions of degrees.

Nuclear fusion is so high that no solid substance can withstand it, and it can only be confined by a strong magnetic field. If high-temperature superconductors can be really put into practical use, they can solve the problem of magnetic fields, but the volume will inevitably be huge.

The artificial sun is nuclear fusion. Artificial solar technology is a type of controlled nuclear fusion.

Its meaning is to provide a constant source of energy to human beings like the sun. The sun is actually a giant nuclear fusion reaction.

Reactor (nuclear fusion) is the transfer of two lighter nuclei.

Combine to form a heavier nucleus, and a very light nucleus or a nuclear reaction of particles, in the process, the nuclear fusion reaction converts a part of the reactant-like mass into energy), and the artificial sun is to imitate the nuclear fusion principle of the Bupaiwan sun, providing inexhaustible energy for human beings.

Introduction:

The production capacity and energy supply of artificial suns must be made a reality, and there must be several conditions: first, the high temperature of more than 100 million degrees, second, the long-term confinement in a limited space, and third, the density is high enough. Under the condition of high density, when the body temperature of the plasma reaches more than 100 million degrees, a considerable number of particles can have enough kinetic energy to overcome the repulsion between the atomic nuclei to achieve nuclear fusion reaction, thus generating considerable fusion energy.

Solar energy comes from nuclear fusion.

1. Solar energy is produced by the fusion of hydrogen atoms inside the sun to release huge nuclear energy, and the radiation energy from the sun. The vast majority of the energy required by humans comes directly or indirectly from the sun. Plants release oxygen, absorb carbon dioxide, and convert solar energy into chemical energy through photosynthesis for storage in plants.

2. Fossil fuels such as coal, oil, and natural gas are also primary energy sources formed by the evolution of animals and plants buried in the ground in ancient times over a long period of geological time. The energy contained in the earth itself usually refers to the energy related to the thermal energy in the earth's interior and the energy related to the nuclear reactions.

3. The energy source associated with the nuclear reaction of the atom is nuclear energy. When the structure of the atomic nucleus changes, it can release a large amount of energy, which is called nuclear energy, referred to as nuclear energy, commonly known as atomic energy. It comes from the nuclear fission energy resources stored in the earth's crust when the uranium, plutonium and other fission reactions occur, and the nuclear fusion energy resources stored in the ocean when the deuterium, tritium, lithium and other nuclear fusion energy resources occur when the fusion reaction occurs.

4. Solar energy is the energy produced by the continuous process of nuclear fusion reactions inside the sun. The average intensity of solar radiation in Earth's orbit is 1369W. The circumference of the Earth's equator is 40,076 kilometers, which makes it possible to calculate that the Earth can obtain up to 173,000 tw.

The sun is nuclear fusion. The sun is mainly composed of hydrogen and helium, so it can only carry out nuclear fusion. In the process of fusion, matter is constantly converted into energy, and elements with lighter mass are constantly fused into heavier elements.

As the proportion of heavy elements on the star increases, the pressure of nuclear fusion on the star becomes greater, and the energy production efficiency becomes lower and lower.

Reaction conditions:Nuclear fusion refers to a form of nuclear reaction in which atoms with small masses, mainly deuterium or tritium, under certain conditions (such as ultra-high temperature and high pressure), polymerize with each other to form new nuclei with heavier mass, accompanied by a huge energy release. The nucleus of an atom contains a huge amount of energy, and the change of the nucleus (from one nucleus to another) is often accompanied by the release of energy.
