Predictive and interpretative edge plasma models often rely upon a kinetic neutral particle module. A virtually exact description of atomic, molecular and radiative reactions is provided via Monte Carlo synthesis of the relevant processes. For many integrated edge transport models, such as B2–EIRENE (‘SOLPS’), OEDGE, EDGE2D–EIRENE (all 2D) and EMC3–EIRENE (3D) the EIRENE Monte Carlo code provides this microscopic analysis for the macroscopic plasma flow fields. The current status of the neutral-particle and radiation transport model in the EIRENE Monte Carlo Code is presented. The directions of further developments of the databases are outlined.
