The 1986 nuclear reactor explosion was dramatised this year in the HBO/Sky series Chernobyl. It includes the story of Lyudmila Ignatenko, whose husband was one of the firefighters who tackled the blaze at the nuclear plant. The series has brought her back into public view, with many people critical of her behaviour at the time. Lyudmila tells her side of the story to Olga Malchevska for BBC Russian.
