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.

Laser ablation scheme can cover pretty wide range of intensity regime as a heat source at its laser focus spot from 103 W/cm2 to 1014 W/cm2. These intensities cover the ones expected at the divertor (MFE) and the first walls (IFE) in a reactor. For example expected values are of 10 to 100 MW/m2 at MFE divertor and 109 W/cm2 or higher at IFE first walls. The ablation may include plasma, gas, liquid, or solid: all possible phases mixed at an extreme condition where temperature may exceed 1 eV with corresponding densities. The areas of these mixed phases at extreme conditions (MPEC) have not been systematically studied. The inside of the solid wall becomes so called “Warm Dense Matter” where the details of the states should still be clarified.In our experimental setting up, the ablated plumes can be aligned orthogonally and can cross each other. The collision processes include Coulomb, elastic, molecular, and cluster collisions at the cross point. The characteristics of this experimental platform are introduced and attractive application is indicated.
