摘要：

The safe disposal of high-level radioactive wastes (HLWs) is a critical concern due to the environmental risks posed by radionuclides like plutonium (Pu), which is highly radiotoxic and has a long half-life. Deep geological disposal, such as at the Beishan site in Gansu Province, China, is considered a viable solution for isolating HLWs from the biosphere. However, the potential for tectonic disturbances and fracture networks raises concerns about the migration of radionuclides, making it essential to understand the speciation and mobility of P...
