"but we've learned most of the problem cases and how to handle them." We also learned time and time again how corrupted human society and individuals can be. So while in theory we could do nuclear safe, we often don't. Neither mining, nor maintaining, nor disposing of the waste. We got lucky quite a few times, but having more of it, will likely just result in more incidents. So while I agree that we should not give it up, I also think we should just harness more of suns fusion power of which we got plenty and invest more in storage technology (you can make batteries out of iron and saltwater for example, no rare elements needed for grid storage). Then there is also the huge energy source beneath our feet, which is fueled by fission btw. if you are more into that. Lots of opportunities ..
