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.

Numerical kinetic code capable to integrate the dynamical collisional kinetic equation has been developed. The steady state distribution of ions in a mirror cell with flow-through plasmas has been calculated. It has shown that near separatrix there is a phase-space region with unstable inverted gradient of the distribution function. The dispersion relation of the oscillations with ~ b (b is bounce-frequency of ions) has been treated analytically for simplified model with b = const. Interaction of passing ions with the oscillations has been considered. It is found that passing ions could lead to instability as long as their flow velocity is high enough.
