Abstract
In most of the failed nuclear objects sitting processes the main barriers were not the technical or safety questions, but the problem of communication and reaching the public acceptance about decision. The paper presents one of the possible approaches that could contribute to the more community sensitive, transparent, communicative and finally successful siting process. The computer-supported approach for assessment of LILRW disposal impacts on regional and urban development is one of several modules loosely connected to a spatial simulation model in GIS. The results are shown as cartographic representation of impacts on different land uses and a possible future land use pattern. This model will be used for evaluation of alternative sites from regional and urban development impact aspects and for negotiating compensation schemes for local communities. One of the very important findings of this work is that the modeling outcomes depend more on value assumptions, according to which the input parameters are chosen, than on accuracy of computations. Therefore any conclusion based on the model outcomes should be verified in a wide panel of experts, interest groups and also wider public.
