World Nuclear Performance Report 2016 Asia Edition provides an up-to-date picture of the civil nuclear power sector today and how it is performing across several key metrics, with a special focus on Asia. This report was launched at Singapore International Energy Week. At the start of 2015 there were 436 operable reactors around the world and by year-end there were 439. This increase in reactor numbers came despite the retirement of seven units during the year. A larger number of nuclear power units are under construction than at any other time in the last 25 years, and with another ten new reactors coming online – also a 25-year record for the industry – 2015 demonstrated improving new build performance all round. The existing global fleet generated roughly 10% of the world’s electricity, making up around one-third of the world’s low-carbon electricity supply.
