摘要
本文简要论述了利用天然地质类似物(或类比体),类比评价核废物处置系统的安全性能。地质类比研究是安全评价核废物处置系统的重要方法之一,也是地质学科的新研究领域。目前已有的地质类比研究对象主要有火山玻璃、陨石玻璃、粘土矿物、铁陨石、铜矿床、铀矿床、含Th和REE的铁矿床、天然核反应堆(一种特殊的铀矿床)和火成岩接触带等。最后对我国今后从事同类研究提出了若干建议。
This paper brieflv reviews the use of natural geological analogues in assessments of the safety function of the nuclear waste disposal system. The study of geological analogues is one of the important methods for safety assessments of the radioactive waste repository. It will be a new field for geological research in China. Important natural geological analogues are volcanic glass and meteoric glass(anal-ogues of solidified mass), clay minerals (natural analogues of backfill material), iron meteorite and copper deposits (natural analogues of waste containers), natural nuclear reactors, uranium deposits, iron deposits containing Th and REE and contact zones between igneous rocks and other rocks (natural geochemical analogues of HLW repository).Finally, the author puts forward some suggestions for the research on natural geological analogues in China.
