Nuclear in Sweden

Installed capacity0.27ktoe

Production1.73Mtoe per year


Between 1971 and 1985 a total of 12 nuclear reactors (nine BWRs and three PWRs) commenced operation. The 10 units remaining in service at end-2009 had an aggregate net capacity of 8 958 MWe. Nuclear power provided 42% of Sweden’s net output of electricity in 2008, but its share fell to 37.4% the following year.

Sweden’s coalition government annulled the country’s anti-nuclear policies early in 2009. In May of the same year approval was given for increasing the thermal output of Ringhals 3 by 5%, and test operation of the uprated unit for one year was sanctioned in the following October.

It was announced in June 2009 that the world’s first permanent disposal site for used nuclear fuel would be constructed at Forsmark in eastern Sweden, with site works possibly beginning in 2013.

A capacity expansion of almost 38% for Unit 2 of the Oskarshamn NPP received government approval in April 2010.

Sweden’s nuclear capacity at end-2020 is forecast by the WEC Member Committee to total 10 000 MWe from 10 units, implying that an overall increase of around 1 062 MWe (or 11.9%) is obtained as a result of uprating existing reactors during the years 2009-2020, assuming that no new reactors are brought into service in this period.
