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.

Blanket neutronics experiments were conducted for the development of the water-cooled pebble bed type ITER Test Blanket Module (TBM) using the Fusion Neutronics Source (FNS). Slab mockup assemblies based on the water-cooled pebble bed ITER TBM including water panels and/or a breeder pebble layer were irradiated by 14 MeV neutrons. After the irradiation, the amount of tritium produced in the diagnostic Li2CO3 pellets or breeder pebbles is measured by liquid scintillation counting method. The C/E ratios for the tritium production rate in those experiments are within 1 ± 0.05. A plan of the neutronics test on ITER-TBM and the neutronic diagnostics in the module are discussed. Micro fission chambers and compact activation foil transfer systems to be embedded in TBM are proposed for the neutron flux and neutron spectrum measurements, respectively.
