Certainly not in the case of Tschernobyl or Fukushima in particular.

And to try and project the risk from accidents that happened so far is just foolish. The risk is really not computable because the chance is small (fat tail) and the consequences catastrophic. Additionally proponents want/need to scale up nuclear power (and thus the risk) by orders of magnitude to make a dent in carbon emissions.

And then, on top of all that, any small amount of actually bad intentions or simple incompetence throws off all the careful risk calculations.
