Description
Sodium borosilicate glass matrix incorporating 25 wt % of simulated high level wastes (HLW) oxides from ThO2-PuO2 MOX fuels was developed and leached in high purity water and simulated granitic and tuff ground waters at 70 and 90 degC. The normalized leach rates (NLRs) were in the range of 10-3-10-8 g.cm-2.d-1 and were found to depend on leachant water composition. From the NLRs results activation energies of leaching were estimated. The activation energies (ΔEa) were least for sodium leaching in all three types of water. The Ea in high purity water increased in the order silica > B > Na just opposite to leach rates. (author)
