Newer designs (existing reactors use 1970s technology) are cheaper and faster to build. Look up the concept of "Small Modular Reactors".

If Wikipedia isn’t missing some examples, there’s exactly one of those operating now in Russia. That seems like we might need more data points before proclaiming them cheaper and faster in the present tense.

I’m totally on board for building more but it doesn’t seem like this is a solved problem yet.
