Abstract

High-level radioactive waste can be safely disposed of in deep geological repositories, for which a possible geological environment in Hungary is the Boda Claystone Formation. In the repository site selection, the geochemical investigation of the host rock is necessary including the structural characterization. In this study, the porosity (p%~1.5% and 5.84%) and the T2cutoff value (0.12 ms and 0.10 ms) of two siliciclastic rocks was determined by desktop low-field NMR, the value of which differed from the 3 ms accepted for clay-bound water and the 33 ms for movable water in clastic reservoirs. Based on the T2cutoff, the producible porosity was found to be high, however, based on the T2 distributions, the bound-water types dominate the composition of the water phase of the rock.
