摘要: 在低中放固体废物处置场关闭后的一定时期内仍将继续监护。当监护期结束以后,处置场场址实现无限制或有限制开放,公众可能通过某种途径与处置场填埋废物近距离接触,从而受到填埋废物中的放射性核素的辐射影响。为估算处置场关闭后对环境造成的影响,需对处置场关闭后影响核素释放和迁移的特征、事件以及过程进行分析和筛选。本文依据IAEA研究成果,对国内某低中放固体废物处置场关闭后的景象进行了分析和筛选。分析和筛选结果表明,处置场关闭后景象的选择应在充分调查的基础上,合理确定评价场景。

Abstract: After a low and intermediate level waste disposal facility is shut down, surveillance will be still in place over fora sustained period. When this period ends, the disposal site could be restrictedor unrestricted released. The public may somehow close contact with the waste disposed of, and be impacted by the radiation contained therein. To estimate thepost-closure effect to environment, it is necessary to analyze and select the Features, Events and Processes that can affect the release and migration of radionuclide, directly or indirectly, from a disposal facility. Based on IAEA findings, post-closure scenario analysis and selection was carried out for a low and intermediate level solid waste disposal facility in China. Preliminary results indicate that the scenarios should be properly chosen on the basis of full investigation.
