Investigation of the long-term radiological environmental impact caused by an accumulation of nuclear facilities

The programme for the calculation of the radiological impact on the population via the various exposure pathways has been finished. Results have been obtained by making use of this programme for the Upper-Rhine-Region. By inserting some preparatory work for the German risk study a delay in the documentation occured. The documentation will be issued during the first half of 1977. In a further study the build-up of heavy isotopes in the cores of different reactor types were investigated and the resulting throughputs in a reprocessing plant have been derived. Using attainable decontamination factors, the resulting release rate can be estimated. (orig./RW)
