【摘要】 甘肃北山野马泉地区是我国高放废物处置库预选场址之一。本文以该预选场址为例,在地下水铀、钍含量及其同位素比值测试、分析基础上,计算了铀存在形式,探讨了铀的迁移特征。初步认为,铀在当地的地质、水文地质等环境条件下,迁移能力有限,迁移距离较小。这一认识为预选场址评价提供了重要的信息和依据。更多还原

【Abstract】 Yemaquan region in Beishan area.Gansu province,is one of the preselected sites of disposal repository for high level radioactive waste(HLW) in our country.Taking this site as an example,based on the measurement and analysis of groundwater U,Th content and isotopic ratio,the uranium occurrence species was calculated and the uranium migration feature was explored in this paper.The result shown that the migration ability and distance of U were very limited in the geological,hydrogeological environmental conditions of the site.This cognition provides very important information and basis for the evaluation of Yemaquan preselected site.更多还原
