| Abstract: | Buffer material is an important part of multiple engineering barrier system for the high level radiowaste repository. Since 1980's, researches in this field have been conducted in the world. The authors review the art-of-state progress for buffer material study on bentonite including composition, organic matters, microbial corrosion, pore water chemistry, transformation and nuclide migration etc. , which might be useful for the related study in China. The authors expect that more financial support would be provided for the related research in order to assure the safe disposal of HLW. |
