The top nuclear-powered countries in the world can be distinguished based on several criteria such as the number of operational nuclear reactors, the total nuclear electricity generation capacity, and the percentage of electricity generated from nuclear power. As of my last update in April 2023, here are some of the leading countries in each of these categories:
- United States: The United States has the largest number of operational nuclear reactors and the highest total nuclear electricity generation capacity. The country has been a pioneer in nuclear energy, using it for both civilian and military purposes.
- France: France is notable for generating a significant portion of its electricity from nuclear power, with around 70% of its domestic electricity production coming from nuclear energy. This is one of the highest percentages in the world.
- China: China has been rapidly expanding its nuclear power capacity, with numerous reactors under construction and plans for further expansion. It aims to increase its use of nuclear power to meet growing energy demands and reduce air pollution.
- Russia: Russia has a significant number of nuclear reactors and is also a major exporter of nuclear technology. The country is investing in next-generation nuclear reactors and small modular reactors (SMRs) for both domestic use and international sales.
- Japan: Despite the Fukushima Daiichi nuclear disaster in 2011, Japan still has a considerable number of nuclear reactors. The country has been cautiously restarting some of its reactors after safety reviews.
- South Korea: South Korea relies on nuclear power for a significant portion of its electricity generation. The country has advanced nuclear technology and is also involved in exporting nuclear reactors.
- Canada: Canada is known for its CANDU reactors, a type of nuclear reactor that uses natural uranium as fuel. Nuclear power is an important part of Canada’s electricity generation mix.
- United Kingdom: The UK has a long history with nuclear power and is in the process of modernizing its nuclear infrastructure with plans to build new reactors.
- Germany: Although Germany has been phasing out nuclear power in favor of renewable energy sources, it still had a number of operational reactors as of my last update. However, the country is committed to a complete nuclear power phase-out by the end of 2022.
- India: India has been developing its nuclear power capacity as part of its energy mix to meet growing electricity demands and has plans for significant expansion.
These rankings and data can change over time as countries build new reactors, shut down existing ones, or change their energy policies. For the most current information, consulting recent data from sources such as the International Atomic Energy Agency (IAEA) or the World Nuclear Association would be beneficial.n’s first Indian-origin Prime Minister by King Charles III
