People always think nuclear is boo, scary!
When Katrina hammered New Orleans I was chatting to a US nuclear engineer (on a brew board

) and asked what about the New Orleans nuclear generator, if that got flooded. He said if the oil refinery there got flooded it would be worse.
Do not forget that coal mining, especially the underground version, is one of the most dangerous occupations.
As well as GHG emissions coal fired generators emit uranium and cadmium out their chimney stacks. Other problems can include fires like we saw in Victoria not that long ago.
Neither course is risk free. Neither course.
We know clean coal is bullshit. You burn coal you emit CO2 and CO2 and some other gases are cooking the world.
Modern nuclear does not blow up. We can situate the reactor and the waste depository safely away from active faults and out of reach of tsunamis. There is the Mt Painter abandoned uranium mine etc where waste can be stored. Some can no doubt be stored in deep abandoned lead-silver-zinc mines in Broken Hill, giving that town new life, Olympic Dam etc.
