Sweden’s parliament has approved a bill allowing more commercial nuclear power reactors to be built than previously planned, scrapping the previous cap of 10, as the country seeks to increase power generation and energy security.

The new laws will also allow construction of nuclear reactors at sites other than existing ones. Sweden’s six existing nuclear plants are at Ringhals, Forsmark and Oskarshamn.

“The Riksdag shares the government’s assessment that fossil-free nuclear power will continue to play a central role in the Swedish energy mix,” the parliament said in a statement.

“The main reasons for this are an expected greater demand for electricity in combination with the need to phase out fossil fuels, not least for climate reasons,” it added.
