Course description and aims

Modern society, while taking advantage of the benefit from the advent of science and technology including nuclear energy, need to assess, understand and govern the risks arising from their use. Through the lectures and discussions in this topical area by faculty members and lecturers from outside, students are expected to deepen their understanding of risk and risk management.

Student learning outcomes

To acquire knowledge of risks, risk assessment and risk management as well as the capability to think about risks; and thereby contribute to the Society as a leader in risk management such as by appropriately project, prepare and respond or by appropriate decision-making.
