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.

Macroscopic behavior of a high-beta and supersonic plasma flow is investigated in the HITOP device. It is found that a cylindrical plasma begins to rotate eccentrically around the center axis in a divergent magnetic mirror. The eccentric radius increases with the increase in the mirror ratio and the beta value of the plasma. The rotating frequency changes with the radial electric field in the plasma, which is controlled by end-plate biasing technique. The rotation direction and its velocity are consistent with E × B drift motion. This behavior seems to be a flute/ballooning mode driven by static and dynamic pressure gradient in a bad curvature region of the divergent field line.
