A new study entitled Business Risks and Costs of Nuclear Power has concluded that the cost of power from new nuclear plants is 25 to 30 cents per kilowatt-hour (kWh) - three times current US electrical rates.
According to ClimateProgress, the report was written by a leading expert in power plant costs, Craig A. Severance. A practicing CPA, Severance is co-author of The Economics of Nuclear and Coal Power (Praeger 1976), and former Assistant to the Chairman and to Commerce Counsel, Iowa State Commerce Commission.
Further, a recent story in Time magazine recently concluded "new nuclear energy is on track to cost 15¢ to 20¢ per kilowatt-hour. And no nuclear plant has ever been completed on budget."
Back to the Severance report:
Recent construction cost estimates imply capital costs/kWh (not counting operation or fuel costs) from 17-22 cents/kWh when the nuclear facilities come on-line. Another major business risk is nuclear’s history of construction delays. Delays would run costs higher, risking funding shortfalls. The strain on cash flow is expected to degrade credit ratings.
Generation costs/kWh for new nuclear (including fuel & O&M but not distribution to customers) are likely to be from 25 - 30 cents/kWh.
Personally my opinion is that the main roadblock to new nuclear power plants is the high cost, and if this report is even in the ballpark, it's simply not a feasible option. Personally I prefer renewable options which can provide baseload power such as geothermal and concentrated solar thermal.
