Selenium-79 (6.5 × 10-5 years) and Technetium (2.1 × 105 years) are the concerned fission products in nuclear waste repositories.Se(Ⅳ) and Tc(Ⅶ) are the dominant species under enviromental condition, respectively.They have highly potential migration capacity from repository to geosphere because of the anionic exclusion between their anionic species and the nagative surface of bentonite [1].
