As long we don’t have a way to deal with the nuclear waste, nuclear is not safe.
And even if we had a way to deal with this, Mining, preprocessing, building the reactor, running the reactor and treating the waste has to be cheaper than renewabls, which I doubt.
Last, but not least, building such powerplants takes years, if not decades, to build, which we don’t have. At the current rate of emission, we have less than 6 years left before we miss the 1.5°C target[1], which is way to short for any nuclear facility.
