Technology No. CW-24-14

FROG, the Fusion neutron Generator, is an innovative code developed to simulate high-energy neutron yields from fission-fusion reactions, utilizing the Geant4 toolkit to facilitate the design of devices that generate fusion reactor-like neutron spectra within thermal fission reactors.

As the quest for sustainable and efficient energy sources intensifies, fusion technology emerges as a pivotal area of research. Traditional neutron generators fail to produce the high-energy flux required for advanced nuclear research and material testing. FROG addresses this gap by providing a sophisticated simulation environment for the development of neutron converters that bridge thermal and fusion neutron energies, crucial for experimental and material research in nuclear physics.

Built upon the Geant4 particle transport Monte Carlo toolkit, FROG enables users to design and simulate neutron converter devices, specifically tailored for integration within nuclear fission reactors. This tool models the complex interactions leading to high-energy (14 MeV) neutron production through a two-step fission-fusion process involving tritons from Lithium 6 or Helium 3 and deuterium. By allowing for customizable device geometries and materials, FROG serves as an invaluable resource for creating neutron spectra analogous to those found in fusion reactors, thereby supporting a wide range of nuclear research applications.
