Nuclear Power Worldwide - Status

Nuclear power, in step with growing global demand for energy, will continue expanding into the next two decades, says the 2008 edition of Energy, Electricity and Nuclear Power Estimates for the Period to 2030, just published by the International Atomic Energy Agency (IAEA). The report is produced every year since 1981, provides high and low projections - very general growth trends whose validity must constantly be subjected to critical review, the report states. The IAEA provides energy planning assistance to its 145 member states.

The low projection assumes that all nuclear capacity currently under construction or in the development pipeline gets constructed and current policies, such as phase-outs, remain unchanged. In such a scenario there would be growth in nuclear electricity production capacity to 473 gigawatt electrical (GW[e]) from the current 372 GW[e]. (A gigawatt is one billion watts). Rising costs of natural gas and coal, coupled with energy supply security and environmental constraints are among factors contributing to nuclear´s growth, said Hans-Holger Rogner, Head of the IAEA´s Nuclear Energy Planning and Economic Studies Section.

Mr. Rogner said that new environmental constraints such as entry-into-force of the Kyoto Protocol and the European carbon trading scheme mean there is now a real financial benefit to avoiding greenhouse gas emissions, adding to the appeal of low-carbon electricity generation, including nuclear power and renewables. The complete nuclear power chain - including uranium mining, reactor construction and waste disposal - emits only 3 – 24 grams of carbon dioxide per kilowatt-hour, about the same as wind and hydro power, and well below coal, oil and natural gas.

The IAEA´s high projection, based on government and corporate announcements about longer-term plans for nuclear investments, as well as potential new national policies, such as responses to new international environmental agreements to combat climate change, estimates nuclear power electricity capacity would grow to 748 GW[e] by 2030.

From 2007 to 2008 the report says, total global electricity generation rose 4.8% while nuclear power´s share dropped to 14% from a nearly steady rate of 16 - 17 per cent between 1986 and 2005.
