Excellent little comment at CiF:
Electricity Generated by Nuclear Power 1970-2006 = 2,080,435,274 MWh
Estimated Decomissioning Cost = 85,000,0000,000
Cost per MWh = 2.5 pence per MWh
Cost per kWh = 0.25 pence per kWh
Sure 85 billion is a big number but we got alot of (carbon free) electricity over the last 40 years.
And of course those numbers include the research and development costs of the nuclear industry as well: they\’re vastly higher than the costs of a new generation of plants.
