9pm - 10pm: Britain's Nuclear Secrets: Inside Sellafield - "Physicist Jim Al-Khalili explores the history of the nuclear facility near the village of Seascale in Cumbria, investigating Britain's attempts - past, present and future - to harness the power of the atom. He examines the ways waste and spent fuel rods have been stored there over the past 70 years and looks at the latest attempts to try to clean some of it up, from storage in vast open-air ponds to encasing pieces of old reactors in concrete blocks"

10pm - 10.15pm: Mick Jackson Remembers - Threads - "The director and producer looks back on the BBC's apocalyptic drama, Threads, sharing the story behind the creation of this acclaimed vision of Britain suffering the effects of nuclear war. Taking Sheffield as the focal point for the aftermath, the film was highly praised for its examination of the social, economic and environmental damage that such a war would bring"

10.15pm - 12.10am: Threads - "Harrowing drama about the consequences of nuclear war, focusing on two Sheffield families in the days leading up to - and the years following - a direct hit on the city. First shown in 1984, the award-winning film pulls no punches in its depiction of the fallout. Reece Dinsdale and Karen Meagher star"
