The World Nuclear Association is the international organisation representing the global nuclear industry. The WNA's World Nuclear Outlook Report 2025 forecasts global nuclear capacity reaching 1,428 GWe by 2050 — nearly quadrupling from 2025 levels — assuming policy support and streamlined regulation. The WNA advocates for nuclear energy globally, publishes authoritative industry data, and organises the annual World Nuclear Symposium. Its 2025 forecast underpins investment decisions across the entire SMR sector.
