reactor exploded Ten years ago the deadliest accident in the history of commercial atomic power occurred when the Chernobyl nuclear power plant exploded, sending radiation that killed at least 30 and affected thousands more across the then-Soviet Union and Eastern Europe. The explosion happened after a loss of coolant water to fuel rods in the reactor's core triggered a series of irreversible reactions leading to a meltdown and a blast that ripped through the roof of the building.
