极低放废物处置研究进展

REVIEW OF VERY LOW LEVEL RADIOACTIVE WASTE DISPOSAL

极低放废物是国际上近年来新提出的一种放射性废物,目前尚未形成公认的定义和处置方式。本文介绍了研究极低放废物比较早的几个国家对极低放废物的定义,概述了国际原子能机构(1AEA)和一些国家的极低放废物处置政策与方法,综述了极低放废物处置场的安全评价方法,比较了这些国家极低放废物的处置状况,指出了我国研究极低放废物的迫切性和研究方向。

Very low level waste (VLLW) is a new type of radioactive wastes proposed recently.No widely acceptable definition and disposal rules has been established for it.This paper reviews the definition of VLLW in some countries where VLLW was researched early,as well as the disposal policies and methods of VLLW that the IAEA and these countries followed.In addition,the safety assessment programs for VLLW disposal are introduccd.It is proved the research of VLLW is urgent and essential in china through the comparison of VLLW disposal between china and these counties.At last,this paper points out the future development of VLLW disposal research in China.
