Nuclear is a red herring introduced by climate crisis opponents - the plants take decades to get away, are intrinsically dangerous and nobody wants one near them. Meanwhile solar and wind are far cheaper, much much faster to build and can be accompanied by batteries to smooth demand.
Nuclear is far safer than any other power generation method. Nuclear reactors, when not made like Cherynobl’s reactor are safe. There is no intrinsic danger at a nuclear power plant because it is engineered away through fail safes.
If we are going to get serious about the climate change, we need to think long term. Solar and wind is a red herring for base loads; they handle peak events very well when properly placed. Batteries are no where now or in the future production ready to smooth demand at the scale you are talking.
