Who wants a grid where your refrigerator can't run when the wind isn't blowing or the sun isn't shining?
You can't replace base load with intermittent generation sources and expect fewer price spikes.
Ya'll better get busy building those nuke plants like NOW.
No. But depending on what you're replacing with how much capacity, you can get cheaper electricity on average (for example removing coal). And the nuclear exit in europe, apart from germany, happened (and is happening) more to the lack of replacement capacity than expectation of direct replacement by renewables. In germany, the exit was more-or-less driven by fear. New NPPs are really (and I mean really) expensive and there is little expectation that with conventional NPP that can significantly change.
And stability & price are not the same.

Have you looked at construction times in Western Countries, even pro-nuclear ones like france? That's like the worst idea. It'd take at least 20 years with conventional technology. Modular reactors aren't ready right now (and I'd be surprised if they solved the issues that are leading to the reduction in nuclear generation we're seeing around the world, but that question doesn't have a firm answer yet).
The solution is building out renewables and investing in storage. Hydrogen and P2G both don't have any fundamental difficulties, the will to implement them on a large scale just isn't there right now. Even regular electrochemical cells should be doable if needed. Due to wind turbines producing more in winter, you only have to bridge the normal day-night cycle and low-wind periods in winter across the EU.
We'd already be in a better position if we'd have invested more in electrifying stuff, since that usually improves the efficiency (even end-to-end when looking at gas power plants).
