Abstract
The transporting behavior of As, Cs, Sr in vitrification form has been studied using a simulating model of ascending flows.Instrumental Neutron Activation Analysis (INAA) was used to determine the quantity of elements transportation. The results of simulating experiment show that the elements can be transported vertically from the vitrification form by ascending flows in the form of nanoscale particles. Then these elements accumulate continuously in the adsorber above the vitrification form. In addition, when the temperature difference between the ground surface and the environment where the vitrification form disposed increases, the transportation speed of these elements will increase too.
