The IAEA's 'Nuclear Explained' series takes scientific and technical subjects related to nuclear topics and makes them easier to understand. Delve into our top explainers in 2024 to find out how nuclear science and technology can be used to produce clean energy; measure how coastal ecosystems help limit climate change; and how radiation and radioactive isotopes can be used for lifesaving healthcare.
1. What is nuclear energy?
Nuclear energy is gaining momentum as countries push to meet their climate targets and reduce greenhouse gas emissions. Nuclear energy was in the spotlight in 2024 as the IAEA and the Government of Belgium organized the world's first Nuclear Energy Summit, and the IAEA raised its projections for nuclear electrical generation for the fourth year in a row. Our explainer on nuclear energy was the most read in English and in all the other UN languages. Read it here. If that leaves you wanting more, take a look at Net Zero Needs Nuclear, the IAEA's Bulletin on the role of nuclear science and technology in achieving a net zero future, or find out more about Small Modular Reactors (SMRs) here.
