Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

An experiment of Alfvén wave excitation and heating of a field-reversed configuration (FRC) plasma is presented. A low frequency magnetic pulse is applied to the FRC plasma by an azimuthally symmetrical antenna. After the pulse applied, an obvious increase of the plasma energy and the propagation of the magnetic wave are simultaneously observed. The excited wave propagates along the steady magnetic field line with the radially distributed phase velocity. The phase velocity outside the separatrix agrees the dispersion relation of the shear Alfvén wave. On the other hand, it is close to the acoustic speed, inside the separatrix. It is also observed that there is a generation of a non-oscillating toroidal magnetic field, which is possible to cause the heating of the FRC plasma.
