【摘要】 深地质处置是目前国际上普遍接受的高放废物最终处置方案。对于这种处置方案而言, 最有可能使处置库系统中放射性核素释放并进入生物圈的机制是地下水的作用。本文阐述了这种地下水的作用,包括地下水与工程屏障的相互作用、地下水在地质屏障中的核素迁移作用及核素滞留作用;介绍了处置库场址评价中水文地质研究的国际进展和动向;重点介绍了我国高放废物处置库预选场址水文地质研究进程和概况。更多还原

【Abstract】 Deep geological disposal scheme is now widely accepted for high level radioactive waste disposal in the world. The most possible mechanism leading to the radionuclide releasing from repository system and entering the biosphere for this disposal scheme is the function of groundwater. This paper describes the groundwater function including the interaction between groundwater and engineering barrier, the radionuclide migration and retardation functions of groundwater in geological barrier. In addition, the progress and trend of hydrogeological research in the assessment of potential repository site in the world are introduced, especially the hydrogeological research progress and general situation related to potential site of high level radioactive waste disposal repository in china.更多还原
