This is a traditional dilema. We weigh the benefit of the small percentage that something could go wrong against the damage that would be cause if that small percentage is the case. If a dam breaks, thousands may drown. If a nuclear facility melts down, millions would be harmed.
theres been 2 major nuclear disaters and both of them havent come close to the death toll that conventional power has produced
1 of those disaters was by carefree russian technicians in an unsafe design, the other was in one of the worlds oldest reactors that survived one of the biggest eathquakes in history and a tsunami with only the
underground generators failing
and they still haventkilled the millions your emotional pleading claims
and your still not addressing my advocation of gen 3 reactors
But as I said, I could go with exteme measures - like placing the plants far away from fault lines or tsunamis or heavy weather but the sequestration of spent fuel is still an issue - a big one. Suppose we managed to go 100 years having dependable and clean energy only to pay for that with the contaminatgion of a major aquifer. Was it worth it?
at the start of the nuclear race there was a big demand for fissionable materials for bombs thats why we've been stuck with the current design for reactors and the offshot of that is radioactive material that has on had a few percentage of energy extracted from it and will stay radio active for hundreds of thousands of years
we know how to remove pretty much all of the energy from that waste and have it radioactive for just a couple of hundred years about the same time that CO2 stays in the atmosphere but without the ecoshpere changing effect
you need to read up on what nuclear is rather than resorting to these emotive attacks on it
