Synopsis: Every first and third Monday of the month, The Straits Times analyses the beat of the changing environment, from biodiversity conservation to climate change.

Nuclear energy is a controversial source of energy that is gaining prominence globally, including in Singapore as a potential solution to tackling climate change. Nuclear is considered a clean form of energy as the generation process does not release any greenhouse gases, unlike the traditional mode of energy generation from burning fossil fuels. 

But following the nuclear disasters in Chernobyl in 1986 and Fukushima in 2011, how safe is this form of energy now? In this episode, The Straits Times environment correspondent Audrey Tan and climate change editor David Fogarty discuss these questions with Dr Matthew Lloyd, a research fellow at the Singapore University of Technology and Design, who does research on materials that can be used in the nuclear process.
