Sweden - World Nuclear Performance Report

There are six reactors operating in three locations in Sweden: Ringhals, 50 km south of Gothenburg; Oskarshamm, 220 km south of Stockholm; and Forsmark, 120 km north of Stockholm.

In October 2022 a pro-nuclear centre-right coalition government took office. In January 2023 the government announced that it was preparing legislation that would scrap both the country’s limit of ten reactors and the
requirement to only build new nuclear reactors at locations where they already exist. The bill was passed by parliament in November 2023. 

Earlier, in August 2023, Sweden’s Radiation Safety Authority (SSM) presented its final report to the government on how the regulatory framework should be developed for nuclear power to be expanded in the country. This followed a government request a year earlier for SSM to review the regulatory framework to ensure there are conditions for using both existing and future nuclear power. 

In November 2023 the government announced plans to construct two large-scale reactors by 2035 and the equivalent of 10 new reactors, including small modular reactors, by 2045. Also in November, Vattenfall sought
planning permission to enable construction of new reactors on the Värö Peninsula at its Ringhals site. In June 2024 the owners of the Forsmark and Ringhals nuclear power plants announced they are assessing the possibility of extending the operating lifetimes of the plants’ reactors from 60 to 80 years.
