This time on Cleaning Up, Michael welcomes Kirsty Gogan back to the show to update us on developments across the world of nuclear energy. Kirsty is co-CEO and founder of TerraPraxis, an NGO and climate solution accelerator, and a leading expert on nuclear power. 

It’s been three years since Kirsty’s last appearance on the show in August 2020, during which we’ve seen new reactors come online across the globe, as well as supply dropouts and wholesale nuclear phase-outs. Kirsty walked Michael through the headlines, as well the rise of SMR (Small Modular Reactor) technology and its potential applications. 

Michael and Kirsty end discussing whether nuclear is offering too little, too late on the path to net-zero in the coming decades, as renewables continue to rise to meet global energy demand. As a one-stop update on all things nuclear, today's Cleaning Up is not to be missed.
