A 1‐D kinetic code has been developed for simulating the transport of neutral particles in the Scrape‐Off Layer using the multi‐energy‐group discrete‐ordinates (S N ) solution method. The S N algorithm, usually applied to time‐independent calculations, has been here extended to the time‐dependent case. The code has been coupled with a 1‐D, 1‐fluid, time‐dependent plasma code, and results comparing the diffusion (S 2 ) approximation with the fully kinetic case are presented.
