The reason why people tend to get a bit cheerleadery about nuclear power is because it has some great PR and it resonates with them.

It needs the PR because it is so unconscionably expensive. The public needs to be primed to consent to indirect and direct subsidies.

The reason China, US, France, it is because it shares a skills base and supply chain with nukes.

The reason Sweden, Poland, Iran, etc. build a few plants is because it shares a skills base and supply chain with a nuclear weapons program they might want in a hurry one day. It's always obvious for those countries who the existential threat is.
