SAFETY ASSESSMENT AND INDICATORS OF GEOLOGICAL DISPOSAL SYSTEM OF HIGH-LEVEL RADIAOACTIVE WASTE
高放废物地质处置系统安全评价及其指标体系

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.
