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.

An analytical model for magnetohydrodynamic flow in a porous medium comprised of a packed bed of uniform spheres is developed. A rectangular geometry only is considered. Two distinct cases are studied: an infinite packed bed and a finite packed bed including wall effect. The wall effect is modeled by employing a two-zone porosity model, with a higher porosity wall region inserted between the solid wall and the lower porosity core region. The effect of the conductivity of the packed bed is accounted for by analogy with Hartmann flow in a duct with an external load. A parametric analysis is performed with the completed model to assess the effects of various factors upon the model results.
