Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

The Alfvén ion cyclotron instability is studied for mirror-confined bi-Maxwellian highly anisotropic plasmas. In such plasmas the wave length of unstable modes is of the order of the plasma scale length. Another specific feature is that a typical ion can execute several bounce oscillations along the strongly non-uniform plasma during the time of the phase divergence between the wave and cyclotron rotation. Traditional approaches such as WKB method and local dispersion relation fail under these conditions.An integral equation for the modes is derived. The spatial distribution of the eigenmodes as well as the marginal stability conditions are found by numerical solution of this equation. The asymptotics of these results in the limit of infinitely large anisotropy are obtained analytically. It is found that the mirror-confined highly anisotropic plasma can be much more stable than it follows from the traditionally used scaling.
