Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

In a high-yield, low repetition rate Inertial Fusion Energy (IFE) system, such as the Z-Pinch IFE reactor, compressible liquid/gas jets offer the opportunity to protect the cavity walls from the target X-rays, ions and neutrons. They can especially limit and mitigate the mechanical consequences of the shock waves produced by rapid heating/evaporation of the protective jets. In this investigation, experiments have been conducted to examine the stability of two-phase jets and quantify the extent by which they can attenuate a shock wave. An exploding wire was used to generate a shock wave at the center of downward flowing annular single- and two-phase jets within a concentric cylindrical enclosure. The pressure history at the enclosure wall was recorded as the shock wave propagated through the attenuating two-phase medium. Experiments were conducted using two different-size jets and enclosures at various liquid velocities, void fractions, and initial shock strength. The data showed that stable coherent jets could be established and steadily maintained with relatively high void fractions and that significant attenuation in shock strength could be attained at relatively modest void fractions. The data obtained in this investigation can be used to validate predictions of shock attenuation models for future IFE reactor cavities.
