Ukraine marks the 30th anniversary of the world's worst nuclear disaster that happened in Chernobyl on April 26. The Chernobyl Nuclear Power Plant exploded in Ukraine, spreading radioactive material across much of the Northern Hemisphere. Thirty years after the world's worst nuclear accident, the Chernobyl nuclear power plant is surrounded by both a hushed desolation and clangorous activity, the sense of a ruined past and a difficult future.
