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.
Technical Session|Panel|Modeling and Simulation for Fusion Neutronics

With the growth of the private fusion industry and a shift in R&D programs toward the engineering aspects of fusion energy systems, the study of neutronics is likely to play an increasingly important role in the overall design of fusion systems. The geometric complexity, deep shielding type problems, and needs for multiphysics integration and uncertainty quantification in fusion systems pose significant methodological challenges to be addressed by the fusion neutronics community. This panel brings together experts from industry, academia, and government laboratories to discuss the current state of fusion neutronics modeling and where challenges lay ahead.
