The Swedish parliament has approved the replacement of old nuclear reactors with new ones, marking a change in policy on nuclear power.
The plan, proposed by the government, passed by 174 votes to 172 against, with three MPs absent.
In 1980, a Swedish referendum decided to phase out reactors by 2010, although the target was later abandoned.
Sweden has 10 reactors, at three power stations, which supply about half of the country's electricity.
The BBC reports the plan allows for new reactors to be built at the same site as the existing plants, but forbids the approval of new sites. The number of reactors is not allowed to exceed 10.
The opposition Social Democratic Party said it would rescind the law if it wins the next election, due in September.
