Rethinking on Influence of Temperature on Diffusion of 75Se(Ⅳ) in Beishan Granite

Abstract

The researches on the diffusion of key nuclide Se in Beishan granite, which is the pre-selected surrounding rock of China’s high-level radioactive waste geological repository, were summarized, including research methods, relevant data obtained and work to be carried out. Moreover, the influence of temperature on the diffusion of 75Se(Ⅳ) in Beishan granite and the possible influence mechanism were analyzed emphatically, in order to provide useful references for domestic peers.
