低中放处置场环境评价参数灵敏度分析

摘要

选取90Sr、239Pu和14C为代表核素,采用单参数变分法对某低中水平放射性固体废物处置场环境影响评价中与核素迁移相关的主要评价参数开展了参数灵敏度分析.分析结果表明:对于低中放处置场而言,环境影响评价模式中主要评价参数的选择对最终评价结果的影响很大,因此在环境影响评价中开展不确定度及敏感度分析是必要的.%Taking90Sr,239Pu and 14C as examples,sensitivity analysis is done for the parameters of nuclide migration,in environmental impact assessment of a low andintermediate level radioactive disposal facility by using method of variation of parameters.The analysis results show that parameters have great influence on final assessment result,and it is necessary that uncertainty and sensitivity analysis should be part of the environmental impact assessment.
