In the early 1980’s my dad had a sticker on his vehicle that said “More people have died in Ted Kennedy’s car than in nuclear power plants”.
More coal miners die in on-the-job accidents every year than have been killed by all US nuclear powerplant mishaps, ever, combined.
The US Navy has been operating nuclear reactors since 1948 and has a cumulative 5400 reactor years of experience. At the moment they manage about 90 reactors, almost all of which are mobile, float, and several of which spend weeks to months continuously underwater. All told, Navy reactors have traveled 128 million miles.
In those 5400 reactor-years and 128 million miles of operation, the US Navy has had one (1) reactor-related mishap that required so much as a crewman being medically examined (USS Guardfish, 21 April, 1973,). Some swabbie opened the wrong valve and let a few gallons (<5) of coolant out. Five crewmen were exposed and later examined and found free of any indications of radiation injury.
You can blame the Selective Service but it was the fault of neither the reactor nor its designer that some pinhead turned the wrong valve.
