The EPR is a new generation (new reactor design). As usual ramping it up implies to build one (the 'tête de série') or at max a few ones, then to launch series. We always did it this way. Since 2005 4 projects were launched (Fran

Indeed. In France the nuclear sector (plants, fuel, research...) has about 220000 jobs.

France already did so. Their current reactor architecture (pressurized-water) was Westinghouse's (France bought a license in the 1970's). They even coined a partnership, see https://pubs.acs.org/doi/10.1021&

I completely fail to understand why some think France didn't try to build new reactors for decades. This is not true! We tried , however it is a running disaster. The problem here isn't "political will". See: https:&#

The political will didn't fail. The EPR reactor in Flamanville is a work-in-progress since 2007. Albeit it was scheduled to start in 2012 it isn't yet. It will cost at least 19.1 billions euros (initial budget: 3.4 billions eur
