Nuclear Free World Policy
These countries are weary of nuclear weapons’ deployment above everything else. Although 8 states are exempted from ban on nuclear weapons, 5 nations retain a de jure status of a “nuclear weapon state.” These states are the United States of America, the United Kingdom, the People’s Republic of China, France and Russia—all of whom had already tested nuclear weapons before the NPT was signed. NWS’s right to possess a nuclear arsenal is countered by Article VI of the treaty, which says that they have a legal obligation to eventually disarm. They also criticized NWS countries for failing to meet their obligation to disarm, in addition to criticizing the 3 states non-signatory nuclear weapons-capable states (which are considered de facto nuclear weapons states). This was stated in point 4 of the Joint Declaration of 1998:
Nuclear power by country
Nuclear power plants currently operate in 31 countries. 
Most are in Europe, North America, East Asia and South Asia.
The United States is the largest producer of nuclear power, while France has the largest share of electricity generated by nuclear power.
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. 
Global nuclear electricity generation in 2012 was at its lowest level since 1999.
China has the fastest growing nuclear power program with 28 new reactors under construction, and a considerable number of new reactors are also being built in India, Russia and South Korea. 
At the same time, at least 100 older and smaller reactors will "most probably be closed over the next 10–15 years".
