Facts and figures

NEA member countries account for approximately 85% of the world's installed nuclear capacity. In the OECD area, nuclear energy represents almost 21% of the electricity supply.

The NEA publication Nuclear Energy Data is an annual compilation of essential statistics on nuclear energy in OECD countries, providing information on plans for new nuclear construction, nuclear fuel cycle developments and projections of installed nuclear capacity to 2035 in OECD member countries. This comprehensive overview of the current situation and expected trends in various sectors of the nuclear fuel cycle provides authoritative information for policy makers, experts and academics working in the nuclear energy field.
