【摘要】 高放废物地质处置系统的安全评价不同于其他工程系统的安全评价,主要表现在:(1) 所考虑的时间尺度长。(2) 所涉及的空间范围大,且具有明显的非均质特征。伴随未来生物圈和近地表环境条件的不确定性而来的是高放废物地质处置系统安全评价将面临的许多不确定因素。主要介绍了高放废物地质处置系统安全评价的基本特征、方法和所采用的安全指标体系。更多还原

【Abstract】 Safety assessment for geological disposal systems of HLW differs from other engineering systems in the following aspects. (1) Extremely long time scales must be taken into account. (2) Natural environments,which are heterogenous and cover large areas,must be evaluated. Therefore,the safety assessment has difficulties in dealing with uncertainties associated with the far future state of the biosphere and the conditions in near-surface zone. This paper describes the feature,methodology and safety indicators of safety assessment for geological disposal systems of HLW.更多还原
