高放废物地质处置进展和安全评价研究

Study on the Progress and Safety Assessment of the Geological Disposal of High Level Radioactive Waste(HLW)

高放废物是一种特殊废物,对其最终处置存在非常大的难度。我国核能工业发展过程中,逐渐累积了大量高放废物尚未得到地质处置。基于国内外相关研究的分析与探讨,深入研究论述了高放废物地质处置的若干关键科学问题,综述了高放废物地质处置库进展及其安全性能评价的特性,旨在为高放废物地质处置安全评价研究的进一步发展提供建议与参考。

High level radioactive waste(HLW)is different from general waste,which is very difficult for final disposal.In the development of nuclear energy in China,a large amount of HLW has been accumulated and has been geologically disposed.In this study,on the basis of the latest progress at home and abroad,it was focused on the discussion of the key scientific issues,and summarized the characteristics of safety assessment in the geological disposal of the HLWs.In addition,it was pointed out the research direction and the urgency of safety evaluation in the next step of the geological disposal of the HLWs in China.
