OK, let's do risk management 101 shall we ?
For a start, let's just remove the clutter of a "small nation getting wiped out by a nuclear accident".
For a start, you'd have to be a *very* small nation to be wiped out by a Chenobyl sized accident, maybe the Vatican but not a "giant" like Lesotho.
I do not see the difference between (say) 50,000 people killed in a small country and 50K in a large one.
And yes, unlike Greenpeace I am prepared to accept that my favoured option has risks. I accept that it is effectively certain that we will experience some truly bad things from nuclear energy.
Using past data points, I guess we will be dealing globally with about one or two thousand deaths per year from accidents. That will be a mix of small and big events. Sometimes we will get 10,000 dead in a year, sometimes very few.
I believe that a rational person cares about dying more than exactly what gets them. So unlike a Greenpeace member a rational person is indifferent between dying of cancer caused by breathing in fumes from carbon fuels as from radiation.
Thus I would not really care if I were the only person to die in my accident, or one of thousands.
A rational person cares about the chances of getting shafted, what we non-Greenpeace types call "probability".
We observe that in Britain, you have about a one in 12,000 chance of dying in a road accident per year. Most people die in single death crashes, but those don't make the news. Train crashes do make the news.
If you were merely to rely upon the media, you would assume that trains were vastly more dangerous than cars. Indeed, recently one might get the impression that one only died in a road accident if criminals were making a getaway or you were shot, both highly rare events.
A trick we non-artsgrad Greens use to tell if an argument is bollocks, is to change the nouns, and see if the logic still makes sense.
Swap the Green "risk" argument against nuclear and you do indeed get them arguingf that trains should be banned. Firemen have been complaining for some time that the channel tunnel trains lack proper firefighting precautions, and that one day several thousand people with die.
But to a Green trains are good, so their risks don't matter.
Of course trains are vastly safer.
If you look at carbon, we see lots of people dying because of oil and coal, but usually in small events, and often because they are coloured the media doesn't bother much, unless it's the latest mass death in Nigeria from poking holes in pipelines.
