Abstract. A phenomenological model for recombination in the scrape-off-layer of tokamak plasma is proposed. Software tools for examination of the model are tested with 1D Particle-in Cell (PIC) simulation of stable plasma in tokamak. The model is validated using global parameters for a 2MW L mode density shot performing 2D calculations of plasma discharge evolution. The role of recombination in different plasma states is discussed.
