Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

Brad Nelson has over 40 years of experience as a lead engineer and engineering manager for projects involving the design, analysis and integration of experimental equipment, systems, and facilities. Before joining Type One Energy as Vice President of Engineering, he worked as Chief Engineer for the US ITER Project, a multibillion-dollar international project to construct and operate the first full-scale fusion reactor.
Nelson’s experience includes mechanical design, analysis, and integration of complex experimental systems for fusion energy research, supervision of associated engineering groups, and coordination of mechanical design, analysis, R&D, fabrication, installation and startup of experimental devices and facilities. Three of those facilities were stellarators, including the Advanced Toroidal Facility and Quasi-Poloidal Stellarator Experiment at the Oak Ridge National Laboratory, and the National Compact Stellarator Experiment at Princeton Plasma Physics Laboratory.
He earned B.S. and M.S. degrees in Mechanical Engineering from the University of Missouri.
