Neutron Transport Simulation

We simulate how neutrons move, scatter, absorb, and interact with matter inside nuclear, plasma, and radiation-related systems. Neutron transport modelling provides essential insight into shielding efficiency, reactor behaviour, activation levels, and safety-critical design parameters.

What Is Neutron Transport?

Neutron transport simulation solves the Boltzmann transport equation to predict the behaviour of neutrons as they undergo collisions, scattering, absorption, and fission events.

Using deterministic (SN) solvers, Monte Carlo particle tracking, and coupled multiphysics models, we calculate flux, energy spectra, reaction rates, and shielding requirements. These simulations are crucial in nuclear engineering, radiation shielding, material activation, and high-energy plasma environments.

Why It Matters
  • Improve shielding design: Ensure adequate protection from neutron radiation.
  • Predict material activation: Understand long-term radioactivity buildup.
  • Enhance reactor safety: Evaluate power distributions and neutron leakage.
  • Optimise research setups: Beamlines, detectors, irradiation chambers, plasma neutronics.
  • Reduce risk and cost: Replace expensive nuclear experiments with validated models.
