Nuclear and renewables do not like to share a grid. Their attributes do not complement each other at all, despite their differences, because fundamentally both of them are not dispatchable. In practice what happens is either nuclear has enough subsidies to survive or renewables completely wreck the economics of it by supplying way cheaper power most of the time.

Both forms of generation want to be paired with something dispatchable, either gas turbines or energy storage. A mix of renewables and nuclear is a mix that is weaker than the sum of its parts, not stronger.
