Repeatedly in recent years there have been calls for a revival of civilian nuclear power. Yet the renaissance never seems to come - on the contrary, nuclear power's share in total energy production worldwide is on the decline.
ZURICH – Repeatedly in recent years there have been calls for a revival of civilian nuclear power. Yet that renaissance never seems to come.
Indeed, of the more than 200 countries in the world, only 30 use nuclear power. In July 2010, a total of 439 nuclear power plants with a net installed capacity of 373.038 GW(e) were connected to various national electricity grids, about 1.2 GW(e) more than at the beginning of 2006.
Roughly 16% of total energy needs (up to 25% in the highly industrialized countries) are now met by electric energy. Nuclear fission’s contribution to total electric energy has decreased from about 18% more than ten years ago to about 14% in 2008. On a worldwide scale, nuclear energy is thus only a small component of the global energy mix, and its share, contrary to widespread belief, is not on the rise.
During 2009, for example, nuclear power plants provided 2,560 TWh(e) (2,560 billion kWh) of electric energy, about 1.6% lower than during 2008 and almost 4% lower than during the record year of 2006, when 2,658 TWh(e) were produced. Early results for the first four months of 2010 for the OECD countries, collected by the International Energy Agency indicate that so far the 2010 results are as low or lower than during the last year.
During the next five years, on average, roughly 10 new nuclear reactors are expected to become operational every year. But this assumes that all of them are constructed according to schedule, and the nuclear industry has rarely met its promised construction deadlines. According to the World Nuclear Association (WNA), 17 new reactors should have become operational between 2007 and 2009. But only five came onstream during this period – three in 2007 and two in 2009.
Moreover, four reactors were de-commissioned during 2009, and a larger number of reactors in Japan and Germany are not in use, owing to various technical stoppages. At least one hundred older and smaller reactors will most likely be closed over the next 10-15 years.

Furthermore, during the past 10 years, only about two-thirds of worldwide demand for nuclear fuel – about 68,000 tons of natural uranium equivalent are needed for 2010 – was met from resources obtained from mining. The remaining 20,000 tons came from so-called secondary uranium sources – mainly inventories held by utilities and governments, re-processed nuclear fuel, and stockpiles of depleted uranium. The supply from these sources will drop by roughly 10,000 tons at the end of 2013, when the Megatons to Megawatt Program between Russia and the United States – which recycles highly-enriched uranium from Russian nuclear warheads into low-enriched uranium for nuclear power plants – comes to an end.
Current projections indicate that uranium shortages in the coming years can be avoided only if existing and new uranium mines operate according to plan. Indeed, extrapolations of global supply that foresee an increase in uranium mining are based on claims about the ability to expand output in Kazakhstan. So far, uranium mining in Kazakhstan has increased roughly as expected, from 4,357 tons in 2005 to 8,521 tons in 2008 to 14,000 tons in 2009.
But it remains to be seen if the uranium mining in this country can indeed increase further to 18,000 tons in 2010 and to 30,000 tons by 2018. According to the WNA’s latest estimates, from July 2010, the expected uranium extraction figure for 2010 has actually been decreased to 15,000 tons.
The view that the amount of energy derived from nuclear power worldwide will continue its slow decrease during the coming years is further supported by the 2008 annual report of the Euratom Supply Agency, which coordinates the long-term uranium needs of nuclear power plants within the European Union. According to the agency’s forecast, uranium demand in Europe will fall from 21,747 tons in 2010 to 17,378 tons by 2018 and roughly 16,000 tons by 2024.
These numbers indicate that the EU, currently producing about 1/3 of the world’s nuclear electric energy, is heading for a reduction in nuclear-energy production of up to 20% over the coming 10 years. One can also expect that the current worldwide economic crisis will not help to accelerate the construction of nuclear power plants and new uranium mines.
In summary, the hard facts about nuclear energy are inconsistent with the possibility of a worldwide renaissance of nuclear energy. Indeed, they point toward a continuing slow phase-out of civilian nuclear energy in most of the large OECD countries.
It thus seems unavoidable that energy consumers, especially in many rich countries, will have to learn to exchange their current worries about the distant future consequences of global warming for the reality of energy shortages during periods of peak demand. Such shortages could result either in chaotic supplies and power outages or in a coordinated policy of energy rationing.
In the absence of nuclear-energy revival, most of us will be forced to reduce our direct energy consumption. Let us hope that we can learn to adapt to simpler – though perhaps still satisfying – lifestyles.
