World Nuclear Outlook Report 2026

Updated Monday, 7 September 2026

The World Nuclear Outlook Report reviews national targets for nuclear capacity and assesses these against the global goal to triple nuclear capacity by 2050. It assesses programme towards those national targets and makes policy recommendations on the additional steps that can help delivery the nuclear capacity required to meet those targets. It also reviews the current and future contribution of nuclear technology to energy provision and summarises the range of different nuclear reactor technologies available.

World Nuclear Outlook Report
Director General’s Conclusions
Global energy demand is rising as populations grow and economies electrify, while emissions must fall sharply. Meeting both objectives will require a major expansion of clean, reliable energy, with nuclear power playing a significant part.
