Lots of people oppose nuclear power. Why? While it's not renewable, at least it doesn't fuck the environment nearly as much as fossil fuels if you don't horribly mismanage the power plants themselves.
There are several reasons other than being scared of accidents.
It has one of the longest time of any fuel type of payoff, including economic and emission reductions; uranium at sufficient qualities to use in existing designs is severely limited and wouldn't even last the lifetime of the plants if they had been scaled up enough to meet the global warming challenge*; and it's actually one of the most expensive options when you look at it. A lot of the costs end up being born by the taxpayer, for example, dealing with the huge nuclear waste dumps we have no idea what to do with. All of those things need to be factored into the lifetime costs.
If nuclear
actually made economic sense then private industry would be clamoring towards nuclear power en masse barely withheld by government regulators and you'd see a proliferation of nuclear power in places with less regulation. We don't see any of that. The only people promoting nuclear are industry lobbyists who make a profit from building and operating the plants. No other segment of industry is calling out for nuclear energy, and that's because they know it's not something that makes anyone else any money. If it made sense, then some big industries who use a lot of electricity would be on the nuclear bandwagon, but there's really nobody in there except for nuclear salesmen. They're the monorails of energy production. The stuff's only even viable with a huge and ongoing influx of taxpayer's money, that goes well beyond the lifespan of the plants themselves. That's why when we bemoan the lack of nuclear, who do we point the finger at? We say "the government" should be doing more to build nuclear plants and roll out the red carpet. If any of it made sense, then that wouldn't make sense. Tesla, for example, makes electric cars, because electric cars make economic sense to make, so they get made, government or no government, and solar gets rolled out with or without the government, because it makes economic sense. Nuclear basically doesn't exist at all unless we pour insanely huge subsidies into it, to make it barely break even with other alternatives. This is why it's not happening, it doesn't make any economic sense for investors. They only even try and build nuclear plants in places with large government infrastructure because then you can leverage the taxpayer to pay for the things. They are a boondoggle.
If John Galt built his libertarian city on the hill, privately funded, there's no way in hell they'd have nuclear, because you couldn't trick other people into paying for the building of it, the security and anti-terrorism, and the safe storage of the inevitable mountains of waste. It's only viable if somebody else is paying for it.
* there are several techs that could make the fuel availability more plausible, however they are all sci-fi basically as none of them are in use. If we need to fix the emissions problem ASAP in the next 20 years we cannot afford to bet on stuff that hasn't been proven to work yet, so at most, those get test projects. Currently we know about 70 years worth of viable fuel for working reactor types, and nuclear makes up 10% of total world electricity generation. Scaling that up by 4 times means the known fuel runs out in less than 20 years, and it'd take 15-20 years to build the plants anyway. There are solid physical reasons we haven't scaled up nuclear much more than it already is scaled up, and just building more plants doesn't solve those problems. We'd already have had more plants if it made any sense to do so. We need to wait 30-40 years until the hypothetical super efficient uranium and/or thorium plants can be built for it to make any sense, and by then we could have just built out all the solar we need since it has a very short time to being emissions positive compared to nuclear.
