Grids should be what, 80% renewables and 20% nuclear base load? It should not matter if renewables are cheaper than nuclear, because 20% base load isn't fungibl

Grids should be what, 80% renewables and 20% nuclear base load? It should not matter if renewables are cheaper than nuclear, because 20% base load isn't fungible for renewables to be swapped in. The natural gas / coal base load is not pricing in it's externalities. The only way nuclear should be going away is if the cost of burning fossil fuels as base load AND capturing 100% of it's emissions is less than nuclear... That or massive grid scale batteries, which doesn't seem plausible anytime in the next couple decades.
