Nuclear power, if all the incidental costs (often absorbed into government 
budgets) for things like liability cover, waste disposal, etc. is not 
overwhelmingly competitive with other sources.   One must also consider the 
capital cost of the production equipment and it's retirement (which is 
quite a bit higher than for, say, coal fired, gas fired, etc.)

Implying that nuclear energy generation costs are <0.0005/kWh?  I find this 
quite hard to believe.  Can you cite a reasonable source for the data? Just 
the capital cost of the generating plant is more than that. (2 GW plant, 20 
yr life, 3.5E11 kWh.  If the plant costs $1B, you're at about $0.003/kWh)

I think that nuclear power, by the time you figure in all the stuff you 
need to, is a bit cheaper than fossil fuel, but not hugely cheaper, and 
certainly not an order of magnitude.

In fact, the chart at the end of  http://www.uic.com.au/nip08.htm shows 
that they're all within a factor of 2:1, except for high cost oil fired. 
(this chart has cost for OECD 1990)

Now there's an interesting prospect... buy your electricity on the open 
traded market, and schedule your cluster computation as the price goes up 
and down. Don't laugh.. it's been done in other industries.
