The Nuclear Legacy

BBC World Service - Witness History, The Nuclear Legacy

The story of how the world was made safe from the former Soviet Union's nuclear legacy

The story of the huge secret operation by Russian and American scientists to make safe the former Soviet Union's former nuclear testing site in newly independent Kazahstan

One of the most potentially dangerous legacies of the collapse of the Soviet Union was its huge nuclear arsenal and nuclear weapons industry. There were particular concerns about the Soviets' former nuclear testing site at Semipalatinsk in Kazakhstan, a vast swathe of contaminated land where there were tunnels with spent plutonium. When the Soviet Union ended, the site was left open to scavengers. Louise Hidalgo has been hearing from the former head of America's nuclear weapons laboratory, Dr Siegfried Hecker, about the long secret operation by Russian and American scientists to make the site safe in what's been called the greatest nuclear non-proliferation story never told.
