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.

The two-dimensional vortex method is applied to the analysis of coolant temperature fluctuations caused by turbulent mixing to examine its applicability to the analysis of thermal striping in liquid-metal fast breeder reactors (LMFBRs). A coaxial jet flow having different temperatures streaming into a stagnant pool is simulated with the method. The calculated velocities are compared with the measurements of an air jet flow. Large scale eddy structures in the mixing region, which cause dynamic large temperature fluctuations, are observed in the numerical simulations. This vortex method can analyze temperature fluctuations caused by large eddies, and is shown to be a useful method for analyzing thermal striping phenomena in LMFBRs.
