Russia and the end of nuclear power
Only China left as a supplier of large nuclear plants
Of the 50-odd nuclear plants currently under construction, around 1 in 3 are Russian VVER designs, being built by Rosatom. Sanctions on the supply of all kinds of electronics mean that few of these will be completed on time, if ever. in promoting sales, Russia has relied heavily on concessional financing through Sberbank, which is also sanctioned. That’s going to make future sales just about impossible, and create big difficulties in fulfilling existing commitments.
With the exception of the EPR money-pit, the only remaining large reactor design still in the market is China’s Hualong One. Given the experience with Russia, buyers outside China may well be cautious about this option.
So, if there is any chance for new nuclear, it rests with Small Modular Reactors, none of which actually exist (there are small reactors, but they aren’t modular, that is, mass-produced).
Modular reactors - the "just swap for coal plants" sort - are about 5 decades overdue, need another decade (or more), need more grants and subsidies to get there and won't be low cost. There may yet be some serious growth for nuclear but it will come later than it might have once (if ever) the Right's Wall of Denial comes down and the current opponents of climate action turn to using the seriousness of the climate problem to promote nuclear instead of downplaying it in support of not having emissions reductions ambitions or nuclear as the right's climate solution.
Criticisms of others for not having nuclear as the solutions (after handing off the issue in "you care so much, you fix it" style to environmentalists who they knew wouldn't support it, in the mistaken belief their "alternative energy" would be a spectacular car crash, leaving the fossil fueled status quo unaffected) is not the same as having nuclear as their own policies and committing to them.
Take Barnaby Joyce - who insists The Greens must support nuclear if they are serious - who's nuclear "policy" is no more than the empty symbolism of overturning the emptily symbolic ban on nuclear power, with (not so emptily symbolic) absolute support for fossil fuels. If he and his ilk have their way it would be all the way to RCP8.5 and beyond, as an inalienable right. Meanwhile the renewables success story is only going to grow. Russia's actions - and responses to it - will reinforce that renewable energy growth.
