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.

A detailed study was conducted on the first wall fabrication process using the reduced activation ferritic/martensitic steel that will be used to fabricate ITER test blanket modules. The effects of the tube-drawing process on microstructural and mechanical properties of F82H is one of the most important issues for fabrication of the module. Square tubes with [hollow square]11 mm × 1.5T (thickness) mm × 3500L (length) mm have been developed by a cold-rolling method. This tube is long enough to fabricate the first wall without any joint in the cooling path. Its surface roughness (Rz) and outer curvature are less than 1 m and 1.4 mm, respectively. Dimensions were accurate enough to reduce the assembly gap for a Hot Isostatic Pressing (HIP) joint. Although the rolling process introduced an elongated microstructure containing dense precipitates, this anisotropic microstructure was successfully recovered by heat treatments corresponding to that used in the HIP process. This work demonstrated that the drawing process could be applicable to a fabrication process for the breeding-blanket component.
