It says clearly about the respective parts of renewables and nuclear in Japan gridpower, before and after Fukushima (which happened 14 years ago).

If a sustainable massive and very quick restart of such heavy industrial equipment seems possible to you after 14 years I stay alert, popcorn in hand.

Sizewell C seems a good deal to the UK because it will in practice the French taxpayer will have to pay for it. Let's see if it happens, or even will be possible. SMRs are an investment-luring ghost ready to explode: https://news.ycombinator.com/item?id=45182003

Sure, there will be some new reactors. Most will be built horrendously over budget and late, obtaining refined uranium and managing their waste will be a growing concern, will produce electricity at a high cost not compensated by any benefit as other ways to compensate 'intermittency' will be more and more effective, any incident will threaten the depreciation of investments, the decommission costs will skyrocket (see nuclear decommissions in the UK, right now)... Good luck with this!

My bet: in 40 years the nuclear industry of nations which expand it now what coal industry is to Germany.
