摘要：

EXAFS at grazing incidence with fluorescence detection has been used to investigate the local atomic structure around uranium at the surface of borosilicate glasses. Structural changes have been observed as a result of leaching in water at 100 degrees C. These indicate that uranium migrates to the surface to form island structures in a surface layer which, subsequently, peels off to reveal fresh surface for further corrosion.
