> When EDF signed a fixed cost contract to deliver nuclear in England the CFO resigned.

Yes, because they had to borrow at a 7 or 9% long term rate on the market (in the era of ZIRP!), which makes financing costs 70-80% of the overall final electricity price.

Of course that kind of deal was insane, but it says more about financing long term projects on the market than it says anything about nuclear as a technology.

> The "profits" are from running decades old reactors that were never transparently costed.

EDF gave more in subsidies to its competitors through ARENH over the past 15 years than what the entire fleet costed.

French nuclear has been an indisputable financial success over the past 40 years (while giving France one of the cheapest electricity in Europe). Saying otherwise is just ignoring reality entirely.
