Course description and aims

This course covers the structure of nuclear power plants and the radiation found there, dismantling technology for long-running nuclear power plants, the generation of dismantling waste, and treatment and disposing technology for the waste, such that students learn the current circumstances around measures for decommissioning nuclear reactors. Through a cost evaluation of removal measures, we will go over the life cycle of nuclear power plants, including waste processing. Finally we will touch on global experience dismantling nuclear reactors, making clear what problems await regarding decommissioning measures.

Student learning outcomes

[Course objectives] This course covers measures for decommissioning and dismantling nuclear power plants, treatment and disposing of dismantled waste, the economics of decommissioning costs, the global situation and issues for reactor decommissioning. Students learn the technological system necessary for decommissioning that will be starting for first generation reactors that have been running for over 40 years.
[Topics] The topics of this course are the structure and life of nuclear power plants, radioactivity of nuclear power plants, dismantling of nuclear power plants, treatment and disposing technologies for dismantled waste, decommissioning costs, and the current global situation and issues for decommissioning measures. Students will learn through these about the current situation and issues for decommissioning technology.
