    Abstract

    An operational puff diffusion model, RINPUPP (Risø Mesoscale PUFF model) has been developed at Risø National Laboratory to provide risk and safety assessments in connection with e.g. nuclear installations. The computer model releases a sequence of puffs with individual pollutant and heat contents, then calculates the time-dependent concentration field, which is provided by the collection of puffs. The puffs are advected through a three-dimensional grid on the basis of a time sequence of measured horizontal wind vectors. The model code is written in standard FORTRAN 77 for a Burroughs B7800 computer. The code also runs on a VAX or a IBM computer. The input data consists of two data files with parameter specifications. In addition, data files with precalculated wind fields and population distribution can be provided. The model outputs for doses,
    puff positions wind and concentration fields consists of disk files and printed data. Graphical presentation of results is based on a specific program, which creates background maps, wind vector plots, puff plots and isoconcentration contours.
