Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.

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.
