1/ "Not industry ready" while (AFAIK) being researched for at least 4 decades is a real problem 2/ Superphenix had numerous non-'political' problems/challenges, see https://en.wikipedia.org/wiki/Superph%C3%A9nix https://en.wikipedia.org/wiki/Superph%C3%A9nix 3/ Fukushima (not the max-case: half of the reactors weren't running at the time of the accident, not built in a densely-populated area...) will costs billions to cleanup https://en.wikipedia.org/wiki/Fukushima_disaster_cleanup#Costs_of_the_cleanup_operations https://en.wikipedia.org/wiki/Fukushima_disaster_cleanup#Cos... 4/ This is either justified, or not. If it is, as we probably both think it is(?), this adds complexity (delays and costs), calling for margins (delays, costs), even w/o knowing the requirements in advance. Every EPR project (in France, Finland or China) largely blowed-up both its schedule and budget.
