Nothing is ever perfectly safe and a lack of perfect absolute safety is not a valid objection. All sources of power have associated risks, even renewables. Wind power has 0.04 deaths per terawatt hour and solar has 0.02 [1]. Nuclear power has 0.03 deaths per terawatt hour (safer than wind), and it's worth noting that almost all of those are from Chernobyl, which was considered unsafe even at the time (they knew about the positive void coefficient). I'm not arguing that nuclear power is perfect, mainly because it isn't. But it's not like all other sources of power are idyllic havens of safety. There are always tradeoffs.
Those figures seem very optimistic. Uranium miners die early, often of horrific cancers.

But the bottom line is that renewable costs are trending down, hard and fast, battery tech is just getting started, and development time for wind and solar is comparatively fast.
Future nuke costs at this point are speculative, development time is very slow, and even if new reactors were commissioned tomorrow, by the time they came online it's very, very likely solar and wind + storage would make them uneconomic.
IMO the attachment to nukes is completely irrational. There are obvious economic downsides, no obvious economic benefits - and that's just the money side.
