国内以海阳核电为代表的第三代核电首次采用了高密度聚乙烯高完整容器。文章介绍了美国Barnwell和Clive处置场HDPE-HIC的处置经验以及国内低放处置场的处置现状,结合我国处置标准要求分析了HDPE-HIC处置要求,并介绍了国内针对HDPE-HIC...国内以海阳核电为代表的第三代核电首次采用了高密度聚乙烯高完整容器。文章介绍了美国Barnwell和Clive处置场HDPE-HIC的处置经验以及国内低放处置场的处置现状,结合我国处置标准要求分析了HDPE-HIC处置要求,并介绍了国内针对HDPE-HIC处置的堆码方案研究,以期为妥善处置HDPE-HIC提供参考。In China, the third-generation nuclear power plant represented by Haiyang Nuclear Power Plant used high-density polyethylene high integrity container for the first time. This paper introduces the disposal experience of HDPE-HIC in Barnwell and Clive disposal sites in the United States as well as the present disposal situation of low radioactive disposal sites in China. Combining with the requirements of China’s disposal standards, the disposal requirements of HDPE-HIC are analyzed, and the stacking scheme research for HDPE-HIC disposal in China is introduced, in order to provide a reference for the proper disposal of HDPE-HIC.展开更多
