Preliminary site investigations were carried out at Kivetty (in Finland), in 1987-1992 in accordance with the investigation programme drawn up by Teollisuuden Voima Oy (TVO). The site was modelled in terms of rock type, fracturing, fracture structures and geohydrological conditions, with the main emphasis being placed on fracturing and associated hydraulic conductivity. The various properties of the bedrock structures were classified in relation to a three-dimensional model. The descriptions of the models were stored in a computer system for the purpose of illustration. The principal rock types encountered at the Kivetty site are porphyritic granodiorite and porphyritic granite, in addition to which even-grained granite and granodiorite, gabbro, and small felsic and mafic veins occur. The rocks have undergone two distinct phases of deformation.
