Nuclear capacity will rise to 619 GW by 2050 if current trends including planned new projects are met, but more collaboration between countries will be needed for robust growth, a report from the Nuclear Energy Agency (NEA) shows.

The OECD NEA Nuclear Energy Outlook: Installed capacity to 2050 and beyond report showed that under current plans nuclear capacity would rise by over 60% from current levels.

According to the International Atomic Energy Agency (IAEA) there is around 379 GW of nuclear capacity in operation today.

The report said that under current scenarios growth would mostly come from non-OECD (Organisation for Economic Co-operation and Development) countries, led by China. It said 70 GW of capacity under construction was around 80% outside OECD countries.
