China is still steadily increasing it's nuclear power capacity, and it's share of total electricity production in China has kept growing, though still only about 5%-6%.

The 2020 National People's Congress reportedly supported aiming for 6-8 new reactors a year, which would double the existing deployment in 6-8 years, and the aim is to not just increase the number of reactors but doing so at a pace that will increase the overall proportion of electricity from nuclear.

For a while it seemed like it would be Japan since they were experimenting with a breeder reactor way back in the ‘80s. After a bunch of false starts it really seemed to be happening in 2010 but then of course the Fukushima accident happened the next year and put a stop to everything: https://en.wikipedia.org/wiki/Monju_Nuclear_Power_Plant

It’s just frustrating to see energy programs fail due to public opinion shift brought on by random perfectly-timed coincidence since there’s not really anything to blame or at fault. Like how The China Syndrome talks about “an area the size of Pennsylvania” and came out exactly twelve days before the actual Three Mile Island accident lol
