IDK, but in Russia nuclear power plants are more than profitable, even with our relatively low electricity prices. Pure total profit of Rosatom from its NPPs electricity is around $10B a year. There even new reactors and power plants rising here, and there are plans to reach 25% of nuclear power in all electricity to 2035. On average, NPP full investments return period is 25 years with investor profit at 10% per year on top (I mean investor will receive 10% of profit a year in addition to investments return during that time). On average, 1kW of nuclear power electricity in Russia cost ~$3K. Yes, it is not a cheapest energy source possible, but perfectly affordable, accounting power stability and no need for permanent fuel supply lines as for combustion power plants or specific landscape as for hydropower. You will pay around same $3k per 1kW if you want a reliable diesel or natural gas backup generator that could run for a week non-stop. Even shitty home grade Generac backup generators cost ~$1k per 1kW and they can't run for weeks. I will instantly pay $3k/kW for personal backup generator that will have reliability and stability of NPP, and need for refueling once in 5 years of runtime.

May be there is something wrong with France and its politics of maintaining and supervising NPPs, and not with nuclear power plants profitability?
