drw

DRW in China has been relatively poorly studied and work needs to be improved in such aspects as site selection standard series, experimental techniques and modeling approaches.

我国放射性废物的处置与研究较为滞后，需在处置场选址规范体系、核素运移试验以及模拟技术等方面取得突破和提高。

While surfing the internet at home, I saw a notice made by DRW ( short for Dalian Rainbow Working Group). It said: We'll hold a swimming activity in Yan Nian on the evening of Apr.

回家上网的时候，我看到了大连彩虹工作组发的一则信息：4月15日晚我们将在彦年海水游泳馆举行活动，以便广大的“同志”们能更好的认识和交流。

Safety of DRW can be achieved by disposal of radioactive wastes with a multi-barrier system.

指出采用多重屏障系统进行放射性废物的处置，其安全性是可以得到保障的；
