Chaired by Academy CEO Dr Hayaatun Sillem CBE, this Critical Conversation discussed the nuclear technologies that can help achieve a decarbonised energy system by 2035, and the challenges faced in delivering them.
As the UK works towards a decarbonised energy system, what will the role of nuclear power be over the next decade or so? What new technologies will help deliver energy decarbonisation? And what challenges do we face in fully realising the technology's role?
We were delighted to welcome Professor Paul Stein CBE FREng and Professor Paul Howarth FREng as panellists for this event.
