Abstract

A R&D programme has been conducted on the main waste streams arising from the operation of PWR power plants, in order to assay the concentrations of a number of longer-lived nuclides such as C-14, Ni-59, Ni-63, Sr-90, Nb-94, Tc-99, I-129, Cs-135, Cs-137 and the transuranium elements. The aim was to evaluate the possibility of deducing the concentrations of the longer-lived critical nuclides from the data on easily measurable key nuclides such as Co-60 and Cs-137, for example by gamma spectrometry on conditioned drums. A number of samples from representative batches of primary water, evaporator concentrates, ion exchange resins and filter cartridges were collected at the different PWR power plants operated in Belgium and destructively analysed in order to determine their content of critical nuclides and key nuclides. In parallel, a number of cemented drums made from the same batches were examined by gamma spectrometry to confirm the concentrations of key nuclides determined by destructive analysis. As an additional verification, some of these conditioned drums were core drilled and the samples analysed destructively.
