Does anyone know of a study/meta-analysis on current fission reactor safety/standards? I would also like to see research/data on the capacity for fission to decrease the rate of CO2 emission. It's a question of which risk is greater. I'm not sure which side is correct in this debate. I think fission is insanely bad for the climate. There are parts of the world we literally cannot go because of fission reactor accidents. I'm lacking data to make an informed opinion and would love some sources. I'm aware modern reactors are safer, but are they really?
