Nuclear Energy Data is the Nuclear Energy Agency’s annual compilation of statistics and country reports documenting nuclear power status in NEA member countries and in the OECD area. Information provided by governments includes statistics on total electricity produced by all sources and by nuclear power, fuel cycle capacities and requirements, and projections to 2035, where available. Country reports summarise energy policies, updates of the status in nuclear energy programmes and fuel cycle developments. In 2016, nuclear power continued to supply significant amounts of low-carbon baseload electricity, despite strong competition from low-cost fossil fuels and subsidised renewable energy sources. Three new units were connected to the grid in 2016, in Korea, Russia and the United States. In Japan, an additional three reactors returned to operation in 2016, bringing the total to five under the new regulatory regime. Three reactors were officially shut down in 2016 – one in Japan, one in Russia and one in the United States. Governments committed to having nuclear power in the energy mix advanced plans for developing or increasing nuclear generating capacity, with the preparation of new build projects making progress in Finland, Hungary, Turkey and the United Kingdom. Further details on these and other developments are provided in the publication’s numerous tables, graphs and country reports.This publication contains 'StatLinks'.
