An apt reference. In both India and China it was the Fukushima disaster that spurred protests and stalled nuclear power growth. Organized environmental activism in both countries is basically nonexistent.
I would rank US-led nonproliferation policies above environmental activism as a cause for slow nuclear adoption as well. (Nonproliferation was primarily a military objective, by the way, not an environmentalist one.) Many countries only have nuclear power programs because France decided to occasionally proliferate them, many times over US objections.
Most non nuclear powers have a few for the same reason Iran does: having some nuclear scientists and a developed nuclear industry around is handy in case of a, uh, geopolitical "emergency". This is why Poland suddenly became interested in 2023 specifically.
Most countries do not want a lot though - it's too expensive.
