The modeling of the deposition of cesium, iodine, and silver in comparison with the PHEBUS FPT1 experiment is examined for two models of the formation of aerosols of fission products: taking account of nucleation and conservative setting of the initial size of the aerosols of nonvolatile components. It is shown that it is important to take aerosols into account in order to calculate the deposition of cesium and silver. The discrepancy between the computed deposition of iodine and experiment is primarily due to the absence of a model of the nonequilibrium chemistry of compounds in the gas phase.
