This way of estimating the real total cost isn't realistic, in such a (military) context accounting is difficult. In France the supreme court of audit (Cour des comptes) simply dropped the ball on it and used ballpark figures. The rea

Not sure about this. For the Koreans (KEPCO) selling (even at a loss) their most recent nuclear plant (at Barakah) was vital because the Korean government then paused nuclear in Korea. Some shortcuts may have been useful ( https:/&#

No. The last reactor delivered by the French, before Olkiluoto-3, was Civaux-2 and it was delivered in 1999 (work started in 1991). Work on Olkiluoto-3 started in 2005.

We already have excess green power (spot prices are sometimes 0 or even negative). There is (now) just not enough of it. However as renewables quickly ramp up there will be more and more of it.

Hydrogen will probably not happen for transportation, but it is a serious contender for power grid backup.

There is no industrial fast-neutron reactor, and therefore nothing (yet) to deploy. Superphenix, in France, never reached the industrial stage. Incidents-riddled, its best performance was, after 13 years, a .31 annual load factor.

The major factors are: France was massively less industrial than Germany, its industrial sector is way less developed than 30 years ago (not emitting is easy when you buy more imported goods), its GDP is quite lower, its climate warmer.

The BN-800 didn't reach industrial stage. Moreover it only runs MOX now (far from a complete closed cycle), just as many classic REP do (for example in France). It has problems and there is no plan to build another one: "problems

Yes, the dose rate (and type of exposure, bioaccumulation of radioisotopes...) is one of (if not the) key parameter. As for its role the document I referenced seems pretty convincing to me.
