alt Hacker NewsNuclear /could/ have solved this years ago but the spectacular and scary nature of failures like TMI or Chernobyl [0] really sunk any chance of that happening. Plus you had all the traditional nonrenewable energy providers intensely interested in stoking fears of that and the question of nuclear fuel storage.
[0] Yes pollution from normal everyday fossil fuel power generation causes more damage and deaths in the aggregate but it's a diffuse hard to attribute kind of damage which makes it far less, for lack of a better way to say it, real to people. eg: Did living downwind of that unupgraded coal plant really kill them or is their death because of something else.

Nuclear has to be the most cultish topic on HN, I swear. Anything less than full-throated support for nuclear gets downvoted into oblivion and it simply doesn't matter how well-reasoned those views are.
To borrow the meme about LISP [1], if nuclear was so good, it would've caught on at any point in the last 80 years. And it hasn't for some good reasons:
- It's too expensive. As an example, Hinkley Point-C in the UK has a super high negotiated rate that only lasts 35 years for a plant that still needs a lifetime of 60 to justify the investment so who knows how expensive the power will be for those last 25 years;
- It takes too long to build, typically ~20 years;
- Fuel processing (to create the fuel rods) creates a lot of harmful waste (eg UF6) and it is not a solved problem;
- Processing of spent fuel is not a solved problem. There's this idea that you just stick it in a barrel and leave it for a thousand years doesn't match the reality. It typically needs active cooling for possibly decades, for a start;
- Failure modes for a single plant dwarf any other alternative. The standard counterpoint is global warming from fossil fuels but that's for the entire fossil fuel ecosystem. The clean up for Fukushima, for example, will likely take over a century and cost over $1 trillion;
- The taxpayer bears the burden for these failures because, in the US for example, the industry self-insurance fund is a couple of orders magnitude too small to cover it;
- Nuclear requires liability limits well below any such failure mode to make it remotely economical (eg the Price-Anderson Act liability limits);
- The ecosystem of building, maintaining, repairing, servicing, monitoring and regulating nuclear power plants as well as all the supply chains (eg transporting and storing fuel) takes a long time to scale up.
I really wish I understood why nuclear has this cult-like following. It's completely irrational.
Price probably played a pretty big role, too. The up front cost of a new nuclear plant is eye watering. Hard to compete against solar & battery these days which can be spun up in months and cost comparatively pennies.
