Spain has seven operable nuclear reactors at five sites across the country, all of which started up in the 1980s. With a combined capacity of 7123 MWe, the units generate over 20% of the country’s electricity.

Until 2011 it was planned that operation of Spain’s reactors would end in the 2020s as operating lifetimes would be limited to 40 years. That restriction has since been removed and the reactors currently in operation are now expected to close by 2035.

In July 2022 the first container holding used fuel from the Garoña plant was placed in the onsite interim dry storage facility.
