Let's say this number is correct: Flamanville has cost a 1/10 of that and has produced 0 kWh, and won't produce any at least 20 years since the project began. Germany produces around 250 TWh worth of electricity per year from renewables, and has done so to an increasing extent in the last 20 years, especially in the last 10. Flamanville Unit 3, I haven't found the estimated production, but judging from the other two units existing it should be in the ballpark of 10TWh per year.
Nuclear has failed to scale, it's a well documented issue. If we want to decarbonize quickly, I cannot imagine how it can make sense to invest a 1/10 for a 1/25 of the production, and then wait decades longer for it. If decarbonization is the goal, projects like Flamanville are already a failure: even if finished it will take decades and decades to make up for the construction time during which it did not produce a single kWh and did not displace a single molecule of co2. Germany was over 50% coal 20 years ago, it would still be at this level if it had gone that route. It can't be the solution now.
