This report compiled the information on distribution and mode of occurrence of uranium deposit was compiled from the published data. Distribution of uranium deposit suggests that geological environments suitable for geological isolation are widely distributed in the Japanese Islands, despite their location in a geologically active area. The mode of occurrence of the uranium deposits indicates that formation of uranium-bearing mineral as well as sorption is expected in both sedimentary and crystalline rocks. The functioning of the natural barrier would be expected in various geological environments in the Japanese Islands, because mineralization and sorption are regarded as a barrier function to retard the migration of radionuclides in HLW, and because of the uranium deposits in the various rock types.

Uranium ore in the Athabasca region, Canada, is highly variable in density. This is due to large variations in the grade of high-density uranium and associated metalliferous minerals, and also to changes in porosity. As it is not practical to take accurate measurements of dry bulk density values of a large number of samples. As a result of investigation on actual ore samples, it has been found practical to estimate the dry bulk density of ore from measured wet bulk density and grain density calculated from chemical data.
