On March 11, 2011, an earthquake large enough to knock the earth from its axis sent a massive tsunami speeding toward the Japanese coast and the aging and vulnerable Fukushima Daiichi nuclear power reactors. Over the following weeks, the world watched in horror as a natural disaster became a man-made catastrophe: fail-safes failed, cooling systems shut down, nuclear rods melted. In the first definitive account of the Fukushima disaster, two leading experts from the Union of Concerned Scientists, David Lochbaum and Edwin Lyman, team up with journalist Susan Q. Stranahan, the lead reporter of the Philadelphia Inquirer’s Pulitzer Prizewinning coverage of the Three Mile Island accident, to tell this harrowing story. Fukushima combines a fast-paced, riveting account of the tsunami and the nuclear emergency it created with an explanation of the science and technology behind the meltdown as it unfolded in real time. Bolstered by photographs, explanatory diagrams, and a comprehensive glossary, the narrative also extends to other severe nuclear accidents to address both the terrifying question of whether it could happen elsewhere and how such a crisis can be averted in the future.
