The pro-nuclear Breakthrough institute in the USA says the new Finnish EPR nuclear plant, with an estimated total cost of $15 bn, will, over its 60-year lifetime, provide electricity at 3.5-3.9 cents per kWh, compared to 16.5-21.5 cents per kWh for Germanys solar PV over their 30-40 year lifetimes. Two EPRs would it says generate slightly more than Germany’s solar PV, at less than a fourth the total cost.

Once people decide to reduce particulate air pollution for health reasons, the “devil’s payment” will be extracted via increased global warming.
