Nuclear and renewables inherently conflict with each other.
The reason is pretty simple. Advances in wind turbine design and manufacturing have made them dramatically cheaper per watt produced when the wind is blowing. Similar advances in solar have brought it’s cost per watt down immensely, to the point that it’s the cheapest form of power in some biomes when it is producing.
So it puts you in a situation where when the sun’s out when the wind is blowing, you actually may be slightly over 100% of grid load just from renewables. Other times, it may be a dark and cold and calm night and you have a huge demand for power.
Nuclear can’t really respond to these load changes. If you ever get a nuclear plant running, you want it to run at full rated reactor power 24/7, and you want customers to be forced to pay per kWh full freight (10 cents or more) for every kWh the reactor produces, all day all the time. Otherwise you just can’t really pay the bills on one of these.
So it just doesn’t work. You don’t want to be installing nuclear reactors if 30%+ of the time, renewables are producing all the power you need.
Instead what you want are cheaper generators, ones that can burn fuel when needed but don’t cost much to idle. So you want a mix of co-gen natural gas plants, which you want to kick on first when the grid needs it. Gas turbine based. And then you want piston engine natural gas generators, because they are the cheapest per watt of generating capacity but less efficient, to kick on during that rare 5-10% when you need it.
And batteries, though batteries are very expensive, so you use them more like a grid-scale UPS, where they only supply power in brief spurts for a few minutes.
You want to make coal illegal because of the air pollution. If you do need to use coal, there are ways to turn it into natural gas without releasing any coal smoke to the atmosphere.
And before anyone comments me on breathless futurism, this is what is happening right now. In Texas, where we have an unregulated grid, there is rapid shift to wind + natural gas by free market forces.
