NATURAL ANALOGUE WORKING GROUP
A brief overview is presented of uranium ore bodies as natural analogues of radionuclide migration in the far field of HLW repositories. Particular reference is made to the secondary mineralization associated with the Koongarra ore body. Attempts have been made to assess the validity of generating equations which form the basis of transport codes. The effect of these phenomena, time dependent sorption coefficients, colloid transport and alpha recoil effects which are not adequately described by many codes $- are discussed. An approach to modelling the distribution or uranium series through separable mineral phases within the host rock is presented. Current attempts to extend the analogue to fractured rocks are outlined. Finally, an approach is suggested for applying the results of natural analogue studies to HLWR site assessment.
