First U.S. nuclear reactor built from scratch in decades enters commercial operation in Georgia::ATLANTA — A new reactor at a nuclear power plant in Georgia has entered commercial operation, becoming the first new American reactor built from scratch in decades.
Proper analysis has been done on this and it’s very achievable. With sufficient storage (which is lower than you’d expect to need intuitively with a full grid + mix of renewables) solar + wind in combination are the cheapest forms of power today. E.g. Here’s a cost analysis by csiro (aus government science body), that includes an optimisatic estimate of costs for nuclear in 2030 with widespread smr adoption. https://www.csiro.au/en/research/technology-space/energy/energy-data-modelling/gencost
Renewables with integration costs are the cheapest by a good margin
