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.

Two experiments directed to a search the experimental conditions for the creation of the hot plasma bunch with β~1 at the multimirror trap GOL-3-II are described. In the first one the hydrogen cloud of 0.5 m length and ~1016 density cm−3 was heated in a short (~ 0.5 m) section with relatively small magnetic field placed in the 12-m solenoid with 9 T magnetic field in mirrors. Plasma pressure was measured by diamagnetic loops and reached βvac ≈0.4. In the second experiment the dense bunch is created by pellet (LiD, (CH2)n) injection into the electron-beam-heated plasma. After beginning of the beam injection the pellet is evaporated and ionized, then dense plasma is magnetized and as result dense bunch (ne=1016-1017cm−3) with abrupt edges is created. After heating the bunch has expansion velocity up to 3·107cm/s.
