Nuclear power stations operate in 31 countries. China has 28 new reactors under construction, and there are also a considerable number of new reactors being built in South Korea, India, and Russia. At the same time, at least 100 older and smaller reactors will “most probably be closed over the next 10-15 years”. So the expanding nuclear programs in Asia are balanced by retirements of aging plants and nuclear reactor phase-outs.

In 2010, before the Fukushima Daiichi nuclear disaster, it was reported that an average of about 10 nuclear reactors were expected to become operational per year, although according to the World Nuclear Association, of the 17 civilian reactors planned to become operational between 2007 and 2009, only five actually came on stream. As of June 2011, Germany and Switzerland are phasing-out nuclear power which will be replaced mostly by fossil fuels, and a smaller part renewable energy.

As of 2012, countries such as Australia, Austria, Denmark, Greece, Ireland, Italy, Latvia, Liechtenstein, Luxembourg, Malta, and Portugal remain opposed to nuclear power. Global nuclear electricity generation in 2012 was at its lowest level since 1999.
