The high level-radioactive waste might lead to sustainable harms to the environment for thousands of years, and the geological disposal has been considered as a preferred proposal for the high-level radioactive waste safety management based on the passive safety. The time scale of the safety assessment could be up to ten thousand years, and the long-term safety assessment is the focus for the application and approval process of the repository site. Therefore, the safety assessment system needs to be simplified for the calculation and the prediction to improve the reliability of the assessment results. This paper reviews the research progress of the geological disposal for the high-level radioactive waste, the passive safety of the geological disposal and the safe management enlightenment of the nuclear technology. Based on the uncertainty safety principle of the geological disposal, the concept of the safety supervision is introduced to provide the technical support for the safe management of the high-level radioactive waste geological disposal.
