Course description and aims

This course is structured in such a way as to gain an understanding of future developments in decommissioning reactors. Students will learn about the decommissioning measures taken for the reactors involved with the accidents at Three Mile Island and Chernobyl, the situation with Fukushima Daiichi Nuclear Power Station, the situation with the fuel debris and technology for removing them, technology for treating (decontaminating) and disposing contaminated water, technology for dismantling the reactors involved, etc. Lectures are held by an operator, invited as lecturer, involved with on-site decommissioning work. Students gain a concrete understanding of issues involved with measures for decommissioning the reactors involved. Students gain an understanding of the processes necessary for decommissioning from an engineering viewpoint, and students are instilled with the fundamental skills for smoothly decommissioning a reactor.

Student learning outcomes

[Objectives] Students in this course will gain an understanding of several issues (removing fuel debris, dismantling the reactor, treating and disposing dismantled waste, contaminated water, and rubble) with the decommissioning measures for the Fukushima Daiichi Nuclear Power Plant, and understanding future developments towards decommissioning.
[Topics] We will cover insights from the decommissioning of reactors such as TMI and Chernobyl, grasping the current situation with fuel debris and its removing technology, and technology for treating and disposing contaminated water, soil, and rubble, as well as future developments towards dismantling reactors and decommissioning measures.
