Abstract

Limiting concentrations of radionuclides (RN) in a granitic environment are determined by computer modelling of a disposal site with quartz sand and clay engineered barriers. Six RN (Sr, U, Pu, Np, Th and Tc) are studied. Temperature is varied with distance from the host rock to waste from 25 to 200°C, The behaviour of these elements appears to be iindependent, of the barrier material and strongly dependent on temperature effect on mineral solubilities.
