World Nuclear Performance Report 2023 highlights nuclear's contribution to clean energy

10 August 2023

In 2022 nuclear energy supplied around 10% of the world’s electricity, and around one quarter of all low-carbon clean electricity. However, the amount of electricity supplied from nuclear energy was 2545 TWh, down 4.2% on the previous year.

The global fall in nuclear generation was due to extended outages in France, the shutting down of reactors in Germany, and the halting of the Zaporizhzhia plant in Ukraine.

However, in Asia, nuclear generation rose by 5%. Nuclear generation in Asia has more than doubled over the last decade.

These facts are included in World Nuclear Performance Report 2023, the definitive publication on nuclear generation and construction, released today.

Speaking at the launch of the report, Sama Bilbao y León, Director General of World Nuclear Association said;

“While growth in nuclear generation in Asia is strong, elsewhere it is not growing fast enough to address the challenges of ensuring energy security, tackling climate change, and providing access to clean energy for all. An increasing number of governments are recognising the value of nuclear generation, but now we must put policies into action, else government and industry commitments will remain as just good intentions.”

World Nuclear Performance Report 2023 contains analysis of global nuclear reactor performance and progress on nuclear construction in 2022, using the latest data from the IAEA. The report also includes updates on countries with nuclear reactors operating or under construction. There are also three case studies examining new nuclear construction and reactor refurbishments.

The report is available on the World Nuclear Association website and can be downloaded for free.
