Of course, you can call me a big nuke puppet (which I'm not) and a despiseful elitist technocrat (which I am) if you wish. Pierre
Is there an obvious summary of the range of estimates available?
What I'd love to see is a range of estimates of the dangers of including nuclear power in the energy generation mix vs. the dangers of not including it, neglecting the bizarro land belief that we will choose to kill technological civilisation and move to some bucolic utopia rather than kill tens of millions of people through global warming and coal fired electrical generation, because we won't - and the transition to that utopia would kill hundreds of millions.
However, there is a danger on the long term, in phasing out the plants (and henceforth, the operating expertise), and stopping development of new generations. It is a technology with very long lead times. We cannot predict with certainty that we won't need it in 20-30 years. Renewables are on a fast growth curve and can go on like that for 30 years, but we cannot be sure about minimal demand.
What I mean is: even with conservation (and certainly demand destruction), total electricity demand may increase due to a crash switch to PHEV, heat pump heating (now installed in 6% of new houses build in France, so it is really taking off)... And demand for non-fossil heat could come from seawater desalination if we have dramatic changes in rainfall patterns.
We have no guarantee that renewables alone can cope with both nuclear/fossil phase-out, and those new demands. Quite the contrary I think for the 20-30 yrs term. Pierre
I also try to keep my points more limited, e.g. I cast doubt at is your claim that we know the risks well, rather than settle down for a figure or a comparison with the risks of a rival technology. *Lunatic*, n. One whose delusions are out of fashion.
That makes it very hard to quantify risks accurately.
If the Windscale fire problem hadn't been solved, it's likely that much of the Midlands would now be uninhabitable. You can more or less get a way with an accident like that in Russia. In Europe, population densities are somewhat higher and the prospect of losing large sections of a country aren't appealing.
So it's not just imputed fatalities, clearly. The overall risk has to include the extremely small - but not quite zero - prospect of a more serious accident.
As everyone else has been saying, the sanest way to assess the risks is to look at governmental competence and corporate culture.
From that point of view, nukes are politically demanding. If insurers don't want to insure them, it could be as much because they know that the political stability and oversight required to minimise risks isn't there, as because they're worried that any trial will be railroaded by hordes of angry chanting hippies wearing sunflowers.
