What’s your point other than people generally sell large projects with a low up front number and it ends up being higher. Investors don’t get the 3-4x return they wanted and have to settle for 2x. Or it takes longer to pay itself back.
Solar and wind are expensive too if they are overbuilt 5x or backed up with enough batteries to be a firm source of power.
How can anyone argue against nuclear being part of the solution of reducing carbon emissions just because it takes more imaginary monetary tokens to build?
Who cares who is building the reactor? Russia and China have the skill and the will to make it happen while everyone else is wringing their hands and continuing to pump out co2.
