But it is not morally acceptable for coal to release radiation either. It was politically acceptable for a while but less so now. It is right to hold new plants to a higher standard. And as I have been reminded repeatedly in these kind of threads it is perfectly possible to build reactors that have negligible radiation release. The real question is if humans really can tweak the tradeoffs like this. Can you really change a design to be less safe on a controllable way. Also, as you say different technologies have different advantages and downsides. That does mean different regulation.
