IAEA inspectors at Fukushima Daiichi nuclear plant

Global nuclear use could increase significantly despite Fukushima

Global use of nuclear energy could increase by as much as 100 per cent in the next two decades, a U.N. report says.

The report by the International Atomic Energy Agency (IAEA), which has not yet been made public, said a somewhat slower capacity expansion than previously forecast is likely after the world's worst nuclear accident in a quarter of a century.

However it said: "Significant growth in the use of nuclear energy worldwide is still anticipated - between 35 per cent and 100 per cent by 2030 - although the agency projections for 2030 are 7-8 per cent lower than projections made in 2010."

Japan's reactor meltdowns at the Fukushima nuclear plant triggered by a deadly earthquake and tsunami on March 11 last year shook the nuclear world and raised a question mark over whether atomic energy is safe.

Germany, Switzerland and Belgium decided to move away from nuclear power to grow reliance on renewable energy instead.

The IAEA document, obtained by Reuters, said the number of new reactor construction starts fell to only three last year - two in Pakistan and one in India - from 16 in 2010.

Also last year, 13 reactors were officially declared as permanently shut down, including the four units at Fukushima as well as eight in Germany.

"This represents the highest number of shutdowns since 1990, when the Chernobyl accident had a similar effect," the Vienna-based U.N. agency said in its annual Nuclear Technology Review.

"As a comparison, 2010 saw only one shutdown and 2009 three."

In 1986, a reactor exploded and caught fire at Chernobyl in the then Soviet Union, sending radiation billowing across Europe.
