Deterministic transport is a methodological approach and research field focused on modeling the movement and interaction of particles, such as neutrons, photons, or other radiation, through a medium by directly solving governing integro-differential equations. This concept investigates the spatial, energy, and angular distribution of particles, their flux, and reaction rates within a system by bypassing statistical sampling methods. Its key characteristic is the precise, non-probabilistic calculation of particle behavior, providing highly accurate solutions essential for the design, analysis, and safety assessment of complex systems like nuclear reactors, shielding, and radiation detectors.
