1. Advantages
1. Clean
Compared to thermal power plants burning fossil fuels, nuclear power plants use nuclear fission reactions to release energy to produce electricity. Nuclear power generation does not produce harmful gases such as sulfur dioxide and does not pollute the air.
2. Environmental protection
Nuclear energy production does not produce carbon dioxide like fossil energy production. The development of nuclear energy can help reduce the greenhouse effect and improve the climate environment.
3 Low consumption
The nuclear fuel consumed by nuclear power plants is much lower than the fossil fuel consumed. by thermal power plants of the same power.
4. Low ecological footprint
Compared to renewable energy sources such as wind and solar energy, energy productionie nuclear power presents significant advantages in terms of ecological footprint and security of energy supply.
For example, solar power generation occupies about 20 times the area of nuclear power generation of the same scale, and wind power occupies about 80 times. Additionally, wind energy and solar energy are greatly affected by weather conditions. Their annual full power operating hours are less than 1,500-2,500 hours, and their operating rate is less than 30%, which is far lower than the operating indicators of nuclear power generation. .
2. Disadvantages
1. Nuclear power plants will produce high and low level radioactive waste, or spent nuclear fuel. Although the volume is not large, care must be taken because. it contains radioactive rays, you have to deal with it and deal with political unrestare considerable.
2. The thermal efficiency of nuclear power plants is low, so they emit more waste heat into the environment than ordinary fossil fuel power plants. Therefore, thermal pollution from nuclear power plants is more serious.
3. There is a large amount of radioactive materials in the nuclear power plant reactor if released into the external environment during an accident, it will harm the ecology and people.
Detailed information
With the increasing depletion of traditional fossil energy and the increasing negative impact of fossil fuel combustion on the human living environment, nuclear energy, regardless of From the economic and environmental point of view, it is an indispensable alternative energy source.
There are three main forms of nuclear energy release:
1. Energyie nuclear fission
The so-called nuclear fission energy comes from some heavy atomic nuclei (such as uranium 235, uranium 238, plutonium 239, etc.), the energy released by fission.
2. Nuclear fusion energy
Two or more hydrogen nuclei (such as the hydrogen isotopes - deuterium and tritium) are combined into a heavier nucleus, and mass loss occurs in same time. Reactions that release enormous amounts of energy are called nuclear fusion reactions, and the energy they release is called nuclear fusion energy.
3. Nuclear decay
Nuclear decay is a much slower natural form of fission, difficult to use due to its slow release of energy.
