Countries O-S


Pakistan has six operating reactors. Because Pakistan is outside the Nuclear Non-Proliferation Treaty due to its weapons programme, it is largely excluded from trade in nuclear plant or materials, which hinders its development of civil nuclear energy.


Construction of the Bataan nuclear plant in the Philippines commenced in 1976 and was completed in 1984. Following the Chernobyl accident in April 1986, the new President, Corazon Aquino, decided not to commission the 621 MWe Westinghouse reactor. The country is considering reviving the Bataan project, as well as the possibility of a small modular reactor.


Poland plans to have nuclear power from about 2033 as part of a diverse energy portfolio, moving it away from heavy dependence on coal.



Romania has two nuclear reactors generating about 20% of its electricity. Romania's first commercial nuclear power reactor began operating in 1996 and its second started up in May 2007. The country has plans for two more units.

Russia: Nuclear Power

Russia is moving steadily forward with plans for an expanded role of nuclear energy, including development of new reactor technology. Exports of nuclear goods and services are a major Russian policy and economic objective.

Russia: Nuclear Fuel Cycle

A major increase in uranium mine production is planned. There is increasing international involvement in parts of Russia's fuel cycle. Exports are a major Russian policy and economic objective.


Saudi Arabia

Saudi Arabia has plans to establish a civil nuclear power industry.


Slovakia has four nuclear reactors generating half of its electricity and two more under construction. Slovakia's first commercial nuclear power reactor began operating in 1972.


Slovenia has shared a nuclear power reactor with Croatia since 1981. It has further capacity under consideration.

South Africa

South Africa has two nuclear reactors generating 5% of its electricity. South Africa's first commercial nuclear power reactor began operating in 1984. Government commitment to the future of nuclear energy has been strong, but financial constraints are severe.

South Korea

South Korea is among the world's most prominent nuclear energy countries, and exports its technology widely. Today 25 reactors provide about one-third of South Korea's electricity from 23 GWe of plant.


Spain generates about a fifth of its electricity from nuclear power. Its first commercial nuclear power reactor began operating in 1968. There are plans for renewed uranium mining. Government commitment to nuclear energy has been uncertain.


Sweden's nuclear power reactors provide about 40% of its electricity. In 1980, the government decided to phase out nuclear power but this policy was repealed in June 2010. In 2015 decisions were made to close four older reactors by 2020, removing 2.8 GWe net.


Switzerland has four operational nuclear reactors. Two large new units were planned. However, in June 2011 parliament resolved not to replace any reactors, and hence to phase out nuclear power by 2034.
