【 摘 要 】

The research activities of this EMSP project at the U. S. Department of Energy Savannah River Site (SRS) are developed for the site-specific needs in the area of high level nuclear waste tanks. Traditional and advanced fracture methodologies are assessed, the crack growth resistance properties for the material of construction (A285 carbon steel) are measured in terms of crack tip constraint, crack growth criteria based on crack opening displacement (CTOD) or angle (CTOA) are developed, and the relationship between stress corrosion cracking (SCC) and the weld residual stress is investigated. All these activities lead to the development of predictive tools for the structural integrity of the SRS waste tanks. The methodologies can be extended to commercial applications.
