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.

Recently, fast alpha-particle-driven kinetic Alfvén waves were investigated by means of a nonlinear turbulent theory, and an analytic expression for the corresponding diffusion coefficient was derived. This diffusion coefficient is introduced in a kinetic alpha-particle transport code based on the solution of a special Fokker-Planck equation by means of a multigroup formalism. The structure of Dα leads to a nonlinear and self-consistent problem. The simulation of realistic International Thermonuclear Experimental Reactor (ITER)-like plasmas by means of a plasma transport code and a description of the anomalous ion and electron transport by the widely accepted Rebut-Lallia model are dealt with. This code is combined with a kinetic alpha-particle transport code to calculate the alpha-particle power deposition profiles to the plasma electrons and the plasma ions. Results are presented for an ignition scenario for ITER-like plasmas. These seem to be the first plasma simulations using a self-consistent alpha-particle transport model. Estimating the effects of anomalous alpha-particle transport is accomplished by repeating each scenario switching off the alpha-particle transport routine and assuming local alpha-particle power deposition. Important physical quantities like density profiles and diffusion coefficients are discussed.
