My understanding from listening to conferences and podcasts is that it is a combination of a lack of mass production (every new reactor is rare and apart, France had economies of scale by building the same design all over the country), unnecessarily tight and ever changing regulations (having to change a design in the middle of construction is always going to derail a project) and lack of private financing (given the upfront nature of the investment with no positive cash flow for 10 years).
