In order to investigate the coupled behavior of Pa release from the wa
ste glass and transport in bentonite, a migration experiment with comp
acted sodium-type bentonite saturated with distilled water was carried
out at room temperature, in which Pu-doped borosilicate glass was san
dwiched. Under these conditions, leaching of Pu from the glass, diffus
ion and sorption of Pu in the compacted bentonite occur simultaneously
.
