N2 - Alteration of borosilicate glass, sintered ceramic, glass-ceramic, and supercalcine ceramic was studied under hydrothermal conditions of 100°, 200°, or 220°C and 300°C for 28 days under a confining pressure of 30 MPa. The solid and solution reaction products were characterized to determine the formation of new crystalline phases and to determine the extent of element release. Analyses of the product solutions determined the partitioning of elements between solid and solution phases. Results show that the chemical composition of the waste, in addition to its form, plays an important role in keeping the hazardous nuclides out of solution during waste-form alteration under hydrothermal conditions that may arise in a nuclear-waste repository.
