Yeah we need a certain baseline production that will always be on. Power needs fluctuate dramatically throughout the day. Maybe we need 100W in the morning but when people come home from work that jumps to 200W. You need to double your power production.
Nuclear takes a while to start up and slow down, so we just keep it at 100W the whole time. Then we have stuff like natural gas and goal which are great to use during peak times. You can turn it up and down very quickly.
If we want to have a nuclear + renewable system with zero fossil fuel usage then we essentially need better energy storage systems. Which people are working on, thankfully.
German nuclear plants can swing from 700MW to over 1300MW per day. Some nuclear plants can manage two swings per day, and these are OLD designs.
I still don't think that would work as a peaker plant, but it's better than nothing! If they really have improved it more than that it might work, but you are going to need at least one power source that can be meaningfully changed multiple times per day.
