Abstract
In the first part, the properties of the transuranium elements (TRU) mainly Pu Np Am have been investigated in terms of complexation by OH and CO3 ligands in aqueous solution. The species which are formed in given physicochemical conditions (ionic strength, concentrations...) are studied with no direct reference to well defined ground waters. Equilibrium constants of complexes and redox potential values are useful in the drawing up of Pourbaix`s diagrams. Areas of stability of species in function of Eh pH pCO2 are given for the different elements in a few cases. The second part of this report deals with the study of the transfer of tritiated water cesium and strontium through highly compacted clay (diffusion coefficient). In a third part a code for the computation of ion migration and diffusion in areas close to radwaste storage facilities has been developed. This type of application was found to require a mesh pattern and boundary conditions different from the usual, which justifies the writing of a new code called CONDIMENT. (Convection and Diffusion of elements) 49 figs.; 18 tabs.; 21 refs.
