bob was right?

IFRs and some of the other newer nuclear fission technologies are probably safer now, taken as a whole, than continuing to build fossil fuel burning power stations.

Is that right? ...

The danger/safety of things at scale are shifty notions - using plastic packaging might prove orders of magnitude more harmful to global ecosystems than the worst possible nuclear power plant disaster.

Not so sure about this ... but I'm feeling that this might be another example of how bad we are at guessing about threat; like when we drive our children to school out of concern for their safety, but expose them to much more probable danger associated with the reduced exercise.
