On April 26, 1986, in a remote corner of Ukraine, 400 times more radioactive material was released into the atmosphere than Hiroshima. What happened inside the Chernobyl power plant that led to the disaster? That's the focus of HBO's miniseries "Chernobyl." Craig Mazin is the creator, writer and executive producer.
