"Baseline power" isn't all that useful. What we need to complement renewables is a reliable source of dispatchable power that can be turned on and off, preferably quickly. Nuclear ain't it. While it's possible to somewhat increase or decrease the output of a nuclear power plant, it's slow, operationally complex, and increases the already formidable costs of nuclear power. It's also not terribly common in the US due to licensing restrictions.
