It already takes longer to build new nuclear starting now than build enough renewable + batteries + transmission starting now. So good news! We don't have to "get there soon", we are there already! We have everything we need except the political will to take resources away from fossil fuels and invest them towards a clean energy future.

Nuclear will continue to be built and it should but it is not the thing we need to focus heavily on.

Japan's mean time to build nuclear is under 5 years, I believe.

And how long from proposal to breaking ground? And how many can we build at the same time? Can we find enough sites or extend existing ones enough? What problems will we have with water shortages for cooling? And so on.

We are, thankfully, going to continue to build nuclear all over the world, perhaps most importantly in places like China where they may convert thermal coal plants to nuclear, but it's going to be a relatively small part of the energy mix overall and is not going to solve the doubt that the poster had and my original response was aimed at. Renewables + batteries + transmission, and I should add efficiency improvements, can do it now, at scale, and faster than we can imagine.
