项目摘要

Disposal of nuclear waste is a critical engineering challenge. The international consensus is that underground disposal is the only viable option. Canada, a major waste producer, is currently at the concept research stage for a high-level repository contained in sedimentary rocks. The cost of a repository will exceed $20B and success relies on accurate prediction and management of the Excavation Damage Zone (EDZ) around repository tunnels, pillars and shafts. The EDZ is a suite of concentric zones of disturbed, damaged and fractured rock that can provide pathways for radio-nucleides. The long term research goal is to improve understanding of the mechanical damage response and robust solutions for engineering control of the damage zone in sedimentary rock, at an repository scale. The five key (short term) objectives for the next 5 years of DG research are:
核废料的处理是一个关键的工程挑战。国际上的共识是,地下处置是唯一可行的选择。加拿大是一个主要的废物生产国,目前正处于沉积岩中高放废物处置库的概念研究阶段。处置库的成本将超过200亿美元,成功取决于准确预测和管理处置库隧道、支柱和竖井周围的挖掘破坏区(EDZ)。EDZ是一套由扰动、损伤和破裂的岩石组成的同心带,可以为放射性核素提供通道。长期的研究目标是提高机械损伤响应的理解和强大的解决方案,在沉积岩中的损伤区的工程控制,在存储库规模。未来五年DG研究的五个关键(短期)目标是:
