By 2045 the government wants to have the equivalent of 10 new reactors, some of which are likely to be small modular reactors (SMRs), smaller than conventional reactors.
Energy Minister Ebba Busch said the government was planning a "massive build out" of new nuclear power by 2045.
"It's decisive for the green transition, for Swedish jobs and at heart for the welfare of our citizens," she told reporters.
Countries like Poland, the Czech Republic, and Britain are looking at expanding nuclear power as societies transition to a fossil-fuel free future.
But critics have pointed to the huge costs and the private sector's reluctance to invest without guarantees or other incentives - like Britain's deal with French nuclear developer EDF for its new Hinkley Point C plant which gave price guarantees.
