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.

Properties of toroidal Alfvén eigenmodes (TAEs), driven by neutral beam injection (NBI) hot ions, are described for the tokamak T-15 under construction in the Kurchatov Institute to test a possible influence on the beam and plasma particle losses. The T-15 baseline scenario with a 10-s flat-top 2 MA current stage, 6-MW NBI plus 6 MW of electron cyclotron resonance (ECR) heating is computed with the ASTRA code. The spatial structure and the frequencies of different TAE modes with the toroidal indexes n = 2 to 8 have been obtained with the ideal magnetohydrodynamic KINX code. The bulk plasma Landau damping, linear growth rates, and nonlinear evolution of the TAE mode amplitudes driven by the NBI ions have been computed with the VENUS code. Our numerical estimations for the T-15 TAE modes are compared with experimental and theoretical results for the DIII-D and NSTX tokamaks.
