Dr Vaibhav Chaturvedi presented a seminar titled ’Implications of risk perceptions for long term future of nuclear energy in India: A sensitivity analysis around nuclear energy cost within an integrated assessment modelling framework' Imperial College London. Dr Chaturvedi started the presentation by highlighting the contentious nature of nuclear energy, and the high decibel debate both for and against nuclear energy. This was followed by a discussion in the nuclear accident liability frameworks of USA, France and India. He then described the controversy around the 'recourse to suppliers' clause of the Indian Civil Nuclear Liability Act. The motivation for the study, that there are significant uncertainties around the evolution of nuclear energy cost, was then presented. Dr Chaturvedi also presented the scenario analysis framework and the integrated assessment methodology of Global Change Assessment Model (GCAM). This was followed by a discussion of key results- that low risk induced costs will not have any significant implications for India's energy future, but higher increased in costs can lead to significant decline in the penetration of nuclear energy; and nuclear energy penetration in India is sensitive to both nuclear energy cost as well as stringency of climate policy, and nuclear liability offsets climate liability. The presentation concluded by highlighting the need for credible risk assessment and more effective communication to reduce the risk perception gap between supporters and sceptics of nuclear energy to delineate an optimal role for nuclear technology in the Indian energy system.
