Know : No. of Nuclear Reactors in the World (Country wise)

Currently, 73 reactors are under construction in 15 countries. Some new countries will be starting their first nuclear power plants including: Belarus, Vietnam, Turkey, United Arab Emirates, Jordan, Ghana, Morocco and Saudi Arabia.

Nuclear power stations operate in 31 countries. 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 June 2011, countries such as Australia, Austria, Denmark, Greece, Ireland, Italy, Latvia, Liechtenstein, Luxembourg,  Malaysia, Malta, New Zealand, Norway and Portugal remain opposed to nuclear power.

Of the thirty countries in which nuclear power plants operate, only France, Belgium and Slovakia use them as the primary source of electricity, although many other countries have a significant nuclear power generation capacity. According to the World Nuclear Association, a nuclear power advocacy group, over 45 countries are giving “serious consideration” to introducing a nuclear power capability, with Iran, the United Arab Emirates, Turkey, Vietnam, Belarus, and Jordan at the forefront. China, South Korea and India are pursuing ambitious expansions of their nuclear power capacities.
