Abstract

Investigations about the characteristics of glasses involved in the solidification of the fission products solutions are carried out as regards to their mechanical and chemical properties. Since the glasses will contain actinide elements, it is necessary to evaluate the possible modifications of these properties versus time. The major problem in doing so is the simulation of a long term storage to make the effects of α- emitters discernable in a relatively short time span. Several methods can be considered: Irradiation by heavy ions in order to match the energy input which would have been dissipated by α- emitters, neutron irradiation to induce either (n,α) or fission reactions, and finally to doping the glasses with various contents of actinides. C. E. A. (Commissariat a l’Energie Atomique) chose the latter. This method is indeed expected to ensure a more realistic simulation.
