Why do nuclear power plants have to be built along the coast?

The reasons why nuclear power plants are built along the coast are as follows:

1, nuclear power plants need a lot of water for cooling, and it is convenient to take water along the coast, so inland nuclear power plants need to build cooling towers;

2. The construction cost of nuclear power plants is very high, which is several times that of thermal power plants of the same scale, while most coastal areas are relatively developed relative to the mainland, and only economically developed areas can bear such costs;

3. Development is restricted within 5km around the nuclear power plant, so that there is enough time to evacuate people in case of an accident at the nuclear power plant. Therefore, the location of the nuclear power plant is generally remote, and the coastal area can reduce immigration.
