Sweden had nuclear phase-out policy from 1980 that was repealed in 2010. In June 2023 Sweden replaced its energy target of "100% renewable" electricity by 2040 with "100% fossil-free" electricity, allowing the government to push forward with plans for new nuclear plants.
Long-term operation
Preliminary studies are to be undertaken at Oskarshamn and Forsmark to explore measures to extend the operating lifetimes of units from 60 to 80 years.
New capacity
Large-scale reactors
In November 2023 the government announced plans to construct two large-scale reactors by 2035 and the equivalent of 10 new large reactors, including small modular reactors, by 2045.
The government has promised SEK 400 billion ($38.2 billion) in credit guarantees to companies that plan to build new reactors.160
Small-scale reactors
In December 2022 Fortum and Kärnfull announced that they were exploring the development of SMRs.
in November 2023, Vattenfall applied for planning permission to build new nuclear generating capacity on the Värö peninsula to the west of the Ringhals plant. Vattenfall said it aims to deploy new nuclear capacity at the site in the early 2030s.
In mid-2024 Vattenfall announced it had shortlisted Rolls-Royce SMR and GE Hitachi Nuclear Energy as potential SMR suppliers next to the existing Ringhals site. In August 2025 Vattenfall said that it had decided that small modular reactors, rather than large reactors, had been chosen to be the form of new nuclear capacity to be built on the Värö peninsula.
The project would be for around 1500 MWe of capacity, either five BWRX-300s or three Rolls-Royce SMRs with start up scheduled for the early 2030s.161
