First of all, it should be noted that fission nuclear power plants are not clean, although they do not produce pollution when generating electricity, but the nuclear waste produced by nuclear reactions is difficult to dispose of, and the slightest carelessness will seriously harm the environment, and once an accident occurs, the consequences will be even worse (such as the Chernobyl accident), in view of the above reasons, some European countries (such as Germany) have implemented a nuclear abandonment policy, no longer build new nuclear power plants, and have closed many original nuclear power plants.
Nuclear power plants using the fusion principle (controlled nuclear fusion) do not have these problems, but they are not yet possible.
The difficulty with controlled nuclear fusion is that the temperature required for the fusion reaction is extremely high, reaching hundreds of millions of degrees. We know that the hydrogen bomb uses the principle of nuclear fusion, in the hydrogen bomb, such a high temperature is obtained by detonating an atomic bomb first, if you want to generate electricity, such a method is obviously not possible.
For the fusion reaction to continue to proceed smoothly, it needs a continuous and stable high temperature, rather than the instantaneous and destructive energy release like the detonation of a hydrogen bomb. But there is no substance in the world that can withstand hundreds of millions of degrees of heat, that is, there is no suitable container for fusion reactions.
It wasn't until 50 years ago that people invented the tokamak device, which seemed to give hope to everyone, and the tokamak device could generate a specific toroidal magnetic field, confined the reactive substances participating in nuclear fusion and the high-temperature plasma in the magnetic field, and the magnetic field became an invisible container. So it was expected that controlled nuclear fusion would be possible in 50 years.
Now, 50 years later, controlled fusion is still practically out of reach, so it is expected that in another 50 years controlled fusion will be put into use, but it is difficult to say whether it will really work in another 50 years.
Controlled nuclear fusion is an extremely complex and difficult systems engineering that involves multiple disciplines, and every bit of progress made in it requires a lot of work. I've also had Shin involved in this work and have experienced first-hand how difficult it can be.
It is precisely because the work is too arduous for any country to complete independently, so there is international cooperation, and at present, many countries in the world have cooperated to launch the ITER project, that is, the International Thermonuclear Experimental Reactor project, China is also the main participating country, and the experimental reactor is built in France. If you are interested, you can take a look at this information.

Yes. The high level of energy required to initiate a fusion reaction is the main challenge in building a fusion nuclear power plant, because it can only be used to build a hydrogen bomb (each with a small atomic bomb) because it can only be obtained through fission reactions. Lasers are known to produce high energy, so some scientists are now experimenting with lasers to initiate fusion reactions.

It is not possible at this time.
But it is possible.
At present, there is an experimental reactor in China.
It's hard to say when it will actually be applied.
If you're optimistic, within 20 years.

Nuclear power plants are built above ground, and reactors are generally underground.
-
Nuclear fuel and reactions are often built underground.

It is estimated that the likelihood of the near future is extremely low, although Hubei Xianning Dafan Nuclear Power Plant, Jiangxi Pengze Nuclear Power Plant, and Hunan Taohuajiang Nuclear Power Plant are the three major inland nuclear power projects. However, due to the Fukushima accident in Japan, the development of inland nuclear power has not yet started.
As for whether it will be built in the future, it depends on the relevant national policies and the situation of nuclear power development.

Nuclear power is to rely on nuclear power to generate electricity, and the current methods of power generation mainly include hydropower, thermal energy, nuclear power, wind power, etc. As China's nuclear technology has been recognized in the world, many small countries have also signed contracts with China to build nuclear power plants, at present, several cities in Zhejiang, Jiangsu, and Guangdong are nuclear power generation, and Hunan is also being built. Nuclear power generation is environmentally friendly, it does not produce thick smoke, does not pollute the land, and wastes resources for power generation.
Small power generation can also use wind power generation, which is also pollution-free, but the power supply capacity is not as good as nuclear power.
-
The development of nuclear power plants is a waste of nuclear energy, and nuclear energy should be used in the pursuit of lightweight and fast transportation equipment.
This small, lightweight, high-energy energy is not wasted on equipment that pursues high speed, or equipment that needs long-term energy** with less transportation costs, or strategic equipment that pursues great power.
Nuclear power plants are easy targets and can cause great disasters if attacked.
The development of nuclear power plants does more harm than good, and now conventional energy sources such as hydropower, wind power, and photovoltaic power generation technology are mature, and it is recommended that the state vigorously promote conventional energy and reduce and abandon nuclear power plants.

Nuclear energy is very powerful, it is a very good energy source,,, now nothing is important, the important thing is energy, the country fights for energy, how important do you say.
-
Wahaha, build the bomb, hehe.
-
Japan is a large industrial country and a developed country with a high level of modernization, and its electricity consumption level is very high (more than 3 times that of us per capita). Japan's existing conventional power generation facilities (mainly thermal power) simply cannot meet the demand for electricity, so Japan needs nuclear power plants (wind power and water resources are not available, 23% of the total number of nuclear power plants in Japan).

Preparation for the future development of nuclear bombs,

It's a bit late. It's nuclear fission.
-
Fission It is said that the sun is nuclear fusion!!
-
Fission, using atomic impact.
The expert is right, the fission is mainly caused by the U-235 substance, and the U-235 fuel for nuclear bombs is extremely rich in more than 95, while the fuel used in nuclear power plants is extremely rich in only 3. For example, if we use fire to light alcohol, it will burn, but if we use fire to light liquor, it will not ignite. >>>More
Whether it is a conventional thermal power station or a nuclear power plant, it is necessary to condense the exhaust steam after the steam turbine is driven to generate electricity, so a large amount of cooling water is required; Due to the high cost of nuclear power plants, in order to dilute the cost, the general unit capacity is very large, and because most of the nuclear power plants have low steam parameters, the heat released through the exhaust steam is much more than that of conventional power plants, therefore, in order to reduce the consequences of thermal pollution, many nuclear power plants are built in coastal areas. >>>More
<> present, there are 17 nuclear power plants and about 40 nuclear power reactors in Germany. >>>More
To be built, Sichuan's *** confirmed. However, the state has not yet approved. The boss of CGN may have some impact if there is a problem, and some work has been carried out at the local level.
The earliest nuclear power plants built in China were in Qinshan, Zhejiang, and Daya Bay, Guangdong. These regions are among the earliest and most economically developed regions in China's reform and opening up. The rapid development of the economy has led to a shortage of electricity, and the main resources of China's power energy are not in the south, so only the construction of nuclear power plants in the south is a good way to solve the local electricity problem.
