The revival of the global nuclear sector has been progressing as the International Atomic Energy Agency (IAEA) has noted that over 110 reactors are planned, with an additional 300 units proposed for the future. Leading the charge to increase energy generation from nuclear reactors are the United States and China, but other nations are also jumping on board the nuclear bandwagon, paving the way for a new era of energy generation from the nuclear market. Following nearly two decades of stagnation, the nuclear sector is set to reach new heights over the coming years.
Debaronizing the global energy market is a shared responsibility
It has become the number one priority for the nations of the world to implement measures to accelerate the decarbonization of the international energy market. Emissions are reaching a tipping point, with climate change becoming all too real across the world.
To accelerate the reduction of emissions from the energy market, a litany of nations has turned to the nuclear sector. The International Atomic Energy Agency’s Power Reactor Information System (PRIS) tracks reactor status worldwide and has reported astonishing growth across the market.
The agency predicts that global nuclear energy capacity could potentially double by 2050, reaching between 561 GW(e) and 992 GW(e). In November, the IAEA noted that 416 nuclear reactors provide a total capacity of 376.3 GW(e) around the international energy market.
The substantial growth of the nuclear energy sector has been led by several nations across the world, such as:
- The United States, which has 94 reactors generating roughly 782 TWh
- China currently operates 57 reactors, and has plans to add 29 reactors over the coming years
- In Europe, France leads the nuclear revival with 57 reactors producing 63 GW(e) and supplying 67.3% of the country’s electricity
- Slovakia’s percentage of electricity produced from nuclear reactors is sitting at 60.6%
- Hungary’s electricity contribution from nuclear reactors is at 47.1%
- Lastly, Finland also relies heavily on nuclear power for 39.1% of its electricity
Investments in the nuclear energy market are reaching astonishing levels around the world
Across the world, 63 reactors are under construction, adding 66.2 GW(e) of capacity to the international market. The projects that came online during the period between 2024 and 2025 increased investors’ confidence in the nuclear sector, such as:
- Barakah-4 in the UAE
- Flamanville-3 in France
- Vogtle-4 in the US
- Kakrapar-4 and Rajasthan-7 in India
- Fangchenggang-4 and Zhangzhou-1 in China
The report from the International Atomic Energy Agency notes that at the moment, 70 reactors are under construction, with an additional 110 being planned for the future. This growth of the nuclear market exemplifies the sentiment for clean energy generation across the global energy market as nations aim to meet their emission targets through clean energy generation, led by the nuclear sector.
With the United States leading the charge for the revival of the nuclear sector, the nation has seen several projects reaching critical landmark deployments over the past few years. Nuclear energy generation can also produce heat for district heating, thereby alleviating the pressure of relying on coal and gas. The future of the renewable energy market is being held firmly and safely in the nuclear sector’s hands.
The nuclear energy market has reached a new era of clean energy production
The significant growth expectations of the nuclear energy market come as several nations report progress in their plans to establish new facilities over the coming years, potentially reshaping the global energy market. For example, the United Kingdom is moving forward with its £2.5 billion flagship SMR program in North Wales. With the report from the IAEA fresh in our minds, the expectations are for the market to reach new highs in the coming years as more projects are commissioned, bringing the standing of the nuclear sector to a new and exciting level.
