Full disclosure: I am not from the industry

1. Yes, fear mongering is a factor. If you are a political power that opposes the nuclear, you can win a couple of points.

2. Dependency on a major player. You can’t just build a nuclear plant as a country. It’s a multinational project and even countries like Turkey rely on countries like Russia for building a plant. The choice is not that wide also: France, China, Russia, or the US.

3. Then, you need to buy fuel from these players. There are a couple of examples where the plants were partially rebuilt to work on fuel from another country, but the drive was always political AFAIK: Ukraine and Finland made themselves independent of Russia’s nuclear supply.

4. It’s a long project with sky-high investment at the start and zero to no profit. It should be politically motivated. Like even in Russia I know of 2.5 newly built nuclear plants since the collapse of the Soviet Union. Others were upgrades of existing plants which require less money. But Russia builds nuclear in Turkey, Egypt, and Bangladesh.
