The method being implemented in the IJnited States and abroad for long-term disposal of high-level radioactive waste is to incorporate the waste into glass. A liquid-fed ceramic rnelter is used to produce this waste glass and to pour it into metal canisters. However, the ther1"1al gradients that occur during the canister filling and cooling process give rise to significant thermal and residual stresses in the glass. These stresses generally result in significant cracking of the glass in the canister. Considerable attention has been given 1 to 48.
