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.

Institut fur Plasmaphysik, Kernforschungsanlage Julich GmbH, Association EURATOM-KFA, Julich, West Germany The variation in the steady state hydrogen permeation flux magnitude through composite metals under both molecular and atomic hydrogen upstream driving conditions is discussed. With molecular hydrogen upstream, the permeant flux magnitude does not depend on the permeant direction through the composite. Under atomic hydrogen bombardment conditions on the upstream side, however, this magnitude does depend on the permeant direction. In a two layer system, the permeant flux magnitude is enhanced by orienting the composite metal such that the layer with the higher product of solubility (S) with surface recombination rate constant (kr) faces downstream. Furthermore, the degree of asymmetry in the hydrogen flow (forward permeation/reverse permeation) increases with decreasing upstream pressure. First measurements on a copper-clad mild steel membrane are presented and confirm the expected permeation performance.
