It's been over 20 years since ive dug into nuclear tech pretty deep but - don't we already have breeder reactors and other tech that is low waste, safer and thus we could build modern (not based on nuclear submarine) reactors in the fission category and deliver cleaner power, today? Yes there is a lot of politics especially around manufacturing, production and storage of spent fuel so all of those are probably show stoppers no matter how safe they are in reality but we aren't invested in it.
