In 1986, the Chernobyl nuclear accident devastated the Soviet Union and shocked the world. But, 40 years on, are we now seeing a nuclear renaissance? And what does that mean for the climate?

Climate Question host Jordan Dunbar has just visited the most contaminated place in the world for a BBC World Service documentary. He tells co-host Graihagh Jackson about the ghostly atmosphere in the former Chernobyl control room and the huge dome that now covers the remains of the nuclear reactor that exploded.

Jordan and Graihagh also discuss how the disaster set back the nuclear power industry for decades. Now, however, nuclear is firmly back on the international agenda because of rising power demand and concerns about energy security.

With around 40 countries now aiming to build more nuclear power stations, what will this mean for the climate and the world’s goal of keeping global warming under control?
