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 Alfvén ion cyclotron (AIC) instability margin in a mirror trap with skew injection of fast neutral beams into a target plasma is investigated in the present work. The instability is driven by inverse population of trajectories of resonant ions having velocity near the injection velocity. So, the stability margin depends strongly on injection details, in particular an injection angle and angular width. The absolute instability margin analysis as well as WKB-analysis on longitudinal and transversal coordinates are used for the stability threshold studying. Simple estimations relating the wave parameters to injection parameters are presented. The stabilizing effect of strong transversal non-uniformity is shown.
