TY  - JOUR
AB - The role of diffusion-controlled ion exchange in corrosion of nuclear waste borosilicate glasses has been examined. Ion exchange is the principal radipnuclide release mechanism in conditions when glass network hydrolysis is suppressed, such as in silica-saturated solutions when it persists over geologic time scales. In dilute aqueous solutions ion exchange controls the initial cation release and can dominate for tens and many hundreds of years if temperatures are low. Ion exchange rates are shown to have square root time dependences, Arrhenius-controlled temperature and exponential pH dependences. Numerical estimates of radionuclide release inventory are given for typical nuclear waste radionuclides. Copyright © 2005 by ASME.
