Why are all the nuclear power plants in China built along the coast?

First of all, nuclear power plants need a lot of water to cool coastal areas to facilitate water intake. If they are inland, they need to build cooling towers. Many inland thermal power plants also need to build cooling towers, that is, those very high chimneys that emit "white smoke", which are actually water vapor. Secondly, the construction cost of nuclear power plants is very high. Most economically developed areas in the world are coastal areas, and only economically developed areas can bear such costs. Moreover, the development is limited to 5 kilometers around the nuclear power plant, in case there is enough time to evacuate people in case of an accident at the nuclear power plant, so the location of the nuclear power plant is generally remote. The number of immigrants in coastal areas can be reduced.
