Why build a nuclear power plant?

As long as all safety facilities and systems work normally, nuclear power plants can ensure that the environment and human body are not harmed by radiation. Therefore, nuclear power plants are safe. When the total installed capacity of the Three Gorges reaches 22 units, the total power is only 32x70=2240 million kilowatts, which is also a small part compared with the total power of nearly 654.38 billion kilowatts in China, and cannot meet the national power demand. Moreover, due to the limitation of rainy season and dry season, hydropower cannot be uninterrupted all the year round. Power generation and hydropower account for 24% of the total installed capacity in China, but the power generation only accounts for 15%. The location of hydropower station is also limited by the geographical location of big rivers. Although hydropower stations can't be built everywhere, with the destruction of the environment, dams have changed the natural course of rivers, and the water flow is slow, which is prone to water blooms. The so-called flowing water does not rot, and the dam blocks the migration channels of fish and other creatures, so salmon wants to come back to swim and produce every year. Eggs go to the upper reaches of the river to lay eggs. The eggs of these fish can only develop normally through the swift current. Building a dam will have a large submerged area, which requires immigration, especially in densely populated areas. Immigration is very difficult. There are 6,543,800 immigrants, and how to resettle these people is also a big problem. However, the area of nuclear power plants is much smaller than that of reservoirs, and the annual fuel consumption is only 30 tons, which is convenient for transportation. No emission of greenhouse gases such as carbon dioxide, sulfur dioxide and nitrogen oxides, and no acid rain pollution. The cost is similar to that of thermal power plants, so nuclear power still has great advantages and needs to be built.
