The traveler was the third and final ORNL participant in a collaborative study of waste immobilization technology with scientists at the Centre de Etudes Nucleaires de Saclay (GEN-S) in France and also visited five other European research centers where research and development (R D) is conducted on the immobilization of hazardous and radioactive wastes. French cements and technology were used to immobilize two low-level radioactive waste streams typical in the US. Results obtained by the previous collaborators, Sams and Mattus, resulted in the selection of two types of French cement which were used to prepare radioactive samples for leach studies. The traveler was also given the opportunity to analyze, in depth, some data from long-term leach experiments. The traveler's visits to the other laboratories in Europe were very enlightening and informative. It was most evident that the Europeans are fully committed to cement-based waste forms and are determined to obtain the understanding and data necessary to convince the regulatory community of the efficacy of this immobilization medium. Since their regulatory climate is quite similar to ours, it would be to our benefit to continue and expand this collaboration on cement-based waste forms.
