摘要
Migration of Cs-137 accidentally released with wastewaters from a nuclear power plant into a system consisting of a wastewater channel and the Dudvah river in Slovakia was modelled. The SMC model used simulated the river by a series of mixed 'reactors' representing sections of the river. Input data for the model were obtained partially by measurements and partially by calibration of the model using several sets of data for activities of river bottom sediments. In this way the space- and time-averaged value of the coefficient of exchange between suspended solids and bottom sediments in the river was obtained and the sediment distribution along the river was refined. The relatively good agreement between the measured and calculated activities of Cs-137 in bottom sediments proved that the activities can be modelled reasonably well using the averaged parameters in the model.
