Advanced excavation damage zone behaviour prediction for immediate and delayed construction response during deep tunneling and deep geological repository development

高放射性核废料的处置是所有核能发电国家面临的一项重大工程挑战。专家们一致认为，地下处置是唯一可行的长期选择。加拿大与许多国家沿着，正在推进高放射性（乏燃料）废物处置的研究和先进计划，目前正在为本国的地下处置库选址。对加拿大人来说，这样一个处置库的最终成本将是数十亿美元，长期的可行性和安全性取决于对处置库基础设施周围引起的挖掘破坏区（EDZ）的管理。安全性评估主要涉及EDZ的最大范围和该受损晕内液体流动性增加的梯度。

Disposal of high-level nuclear waste is a critical engineering challenge for all countries that generate nuclear power. The expert consensus is that underground disposal is the only viable long-term option. Canada, along with numerous countries, is moving forward with research and advanced plans for high-level (spent fuel) waste disposal and is currently in the site selection process for its own underground repository. The ultimate cost to Canadians, of such a repository, will be 10's of $Billions and the long-term viability and safety relies on management of the Excavation Damage Zone (EDZ) induced around repository infrastructure. Safety assessment is primarily concerned with maximum extent of EDZ and the gradient of increased fluid mobility within this damaged halo.
