Introduction to country pages

The Country Pages in this section present summaries of recent developments and performance data for countries with reactors in operation, and updates on those new entrant countries with their first nuclear reactors under construction.

The information for the numbers of operable reactors and reactors under construction is correct as of 31 July 2024.

The lifetime CO2 avoided data is calculated on the basis of the emissions of carbon dioxide that would have been released had the electricity supplied by nuclear generation in each country to 31 December 2023 been  generated by coal-fired power plants instead. The values for emissions avoided annually since 2019 are derived from equivalent electricity generation from coal-fired or gas-fired plant.

The nuclear share of generation figures refer to the percentage of electricity generated from nuclear for 2023. As elsewhere in this report, capacity factors are calculated based only on those reactors that generated electricity in each calendar year. The electricity generation charts show total electricity generation for each year and subdivide this into electricity generation by reactors of different ages, based on the date of first
grid connection.
