Adsorption Behavior of Sr,Cs and Np on Beishan Granite

摘要

90Sr,137 Cs and237 Np are the key radionuclides that need to be considered in studies on deep geological disposal of HLW.As a result of the intrusion and erosion of groundwater,90Sr,137 Cs and237 Np in waste vitrification glass would be eventually leached into the groundwater and migrate in far field of repository.The adsorption behavior of90Sr,137 Cs and237Np on Beishan gran-ite determines the degree of migration of90Sr,137Cs and237 Np,and is also a decisive factor in the safe disposal of HLW in the repository.
