Yes. They have to. (And so do we.) Nuclear power is the only viable means of power we have in the immediate and intermediate future, considering all of the factors, even accounting for all the risks.

Build more nuclear power plants!
In Finland. There are several nuclear power plants in Finland and more are likely to be build.
France produces about 80% of its electricity by nuclear plants, but this is an exception in Europe, most countries with nuclear plants have about 20%, as in the USA. Not sure about Japan, but nuclear appeals there I think because they have little fossil fuels in the country. See www.world-nuclear.org for a more detailed survey.
The reason is that there are many people around the world who are uneducated in the nuclear power field and therefore still assume the stereotypical nuclear meltdown or mutations will occur and as such, oppose their construction vehemently. Also, it is quite expensive to develop and build such plants.
Nuclear power plants are expensive to build and need highly trained engineers to operate. Fear of a nuclear accident and fear of nuclear waste mean many people don't want nuclear plants to be built near them.
There are several reasons for the limited growth of nuclear power compared to fossil fuel plants. One reason is the high cost of building and decommissioning nuclear facilities. Concerns about nuclear accidents and waste disposal also contribute to the reluctance to expand nuclear power. Additionally, the time it takes to build a nuclear plant and the availability of alternative energy sources play a role in the decision-making process.
Yes, nuclear power plants are legal in the United States. The Nuclear Regulatory Commission (NRC) regulates nuclear power plants to ensure they operate safely and securely. There are currently over 90 commercial nuclear power reactors operating in the US.
The generating cost is much the same overall as coal, the fuel cost is lower but the plants are more expensive to build. Most nuclear plants run on base load because the fuel cost is lower.
Nuclear energy makes up 80% of France's energy intake. The USA has over 100 power plants and many countries are building more nuclear power plants (like India and China.) Poland is starting on Nuclear energy in 2020.
The plants are very expensive to build, and could be dangerous in case of an accident.
