Within the SUNRISE project (Sustainable Nuclear Research In Sweden) design, safety analysis and materials development and qualification for a lead-cooled research reactor intended to be constructed in Oskarshamn is carried out. The project partners are KTH, Luleå University of Technology and Uppsala University. SUNRISE is funded with 50 MSEK by the Swedish Strategic Research Foundation and is co-ordinated by Professor Pär Olsson at the division of nuclear engineering at KTH.
