A deep geological disposal is one of the most important ways for the safe treatment of various kinds of radioactive wastes generated by nuclear power and reprocessing plants. This course focuses on the relation between the disposal engineering and natural environments, and explains basic science and technologies in the waste disposal, e.g., vitrified glass, bentonite buffer material, canister, overpack, and rock.
Moreover, the course aims to cultivate students' skills to evaluate the safety and feasibility of the radioactive waste management scientifically.
The goals of this course are as follows.
1. Students can understand the qualities, the safety, and the performances of engineered barrier systems consisting of vitrified glass, bentonite buffer material, canister, overpack, and rock.
2. Students can obtain the scientific knowledge of waste management and the problem solving abilities.
