Studsvik applies to build more reactors; Sweden seeks majority control of SMR company
New developments in Sweden’s nuclear energy industry continue to make headlines. Last week, Swedish engineering services firm Studsvik submitted an application to build between 600 MWe and 1,400 MWe of new nuclear power capacity “at and around” its Nyköping Municipality headquarters. Separately, the Swedish government is looking to acquire a majority ownership stake in Videberg Kraft AB.
