In probabilistic risk assessments, almost all pathways that lead to radiological release in modern reactors is related to decay heat cooling failures. That's the singular safety selling point of Gen IV reactors that have passive cooling features. It was demonstrated in April, 1986 at EBR-II in Idaho, weeks before Chernobyl. Very few people have heard of this awesome capability. https://en.wikipedia.org/wiki/Experimental_Breeder_Reactor_II#Passive_safety https://en.wikipedia.org/wiki/Experimental_Breeder_Reactor_I...
