Model of calculation of fission product transport and deposition in the HTGR primary coolant circuits

A model allowing one to conduct an engineering calculation of diffusion deposition of various fission products on the walls of pipelines and equipment of high-temperature reactor plants with regard to physical and hydrodynamic coolant characteristics, wall properties, temperature conditions and other factors, is proposed. The model is used when developing the RADON program. The intensity of particle deposition on the wall surface is taken into account using a special empirical parameter
