nuclear was being phased out before fukushima anyways in germany, it was just accelerated a few years. New nuclear power plants are just way too expensive - take a look at Flamanville, Hinkley point C, Olkiluoto 3, Wylfa Newydd and Hanhikivi and you'll see that they are just too expensive. You can argue for having the old ones run a bit longer but the older the plants become the more maintenance issues arise.
It's well established that the West has forgotten how to build nukes. But Hitachi, KEPCO, and the Russians have not forgotten, and can build them effectively today. Perhaps with some effort the West can re-learn how its done from these modern success stories.
Wylfa Newydd was a project by Hitachi before it got cancelled despite being guaranteed a higher-than-market compensation of £75 per MWh[0], yet despite those heavy subsidies it apparently is not worht it.
