【 摘 要 】

Radioactive wastes are contained in 48 underground storage tanks at the Savannah River Site (SRS). The materials and structures of the tanks provide a confinement function by maintaining leak integrity and structural stability. It is essential that the potential changes in properties of the structural materials due to service environment be evaluated and that conditions that can cause significant (active) degradation be avoided or mitigated. Aging mechanisms are those which cause changes in the materials including degradation of the materials. Degradation is either a reduction of the mechanical properties (e.g., loss of toughness or ductility), or a loss of net section of materials (e.g., cracking, pitting, thinning), or both which reduces the level of confinement inherent in the original installed condition and could lead to failure of confinement.
