Abstract

Nuclear industry production would produce large amounts of nuclear waste.How to safely dispose of the nuclear waste especially high level radioactive waste (HLW) became increasingly serious problem at present. This article turned out that compaction energy was an important factor of the impact compaction performance through the light and heavy compaction experiments . Adding a certain amount zeolite or attapulgite could get larger maximum dry density and smaller optimal moisture content. In zeolite or attapulgite added to 0%-20% of dry density increased mixed materials, compaction curve was relatively tame. With zeolite or attapulgite increased to 20% to 50%, the pressure increased sharply. But when zeolite or attapulgite increased more than 50%,the pressure of the compaction needed higher. Thus the content of zeolite or attapulgite in 20% to 30% was easier to compact.
