The Willow Island disaster was the collapse of a cooling tower under construction at the Pleasants Power Station at Willow Island, West Virginia, on April 27, 1978. Fifty-one construction workers were killed. It is thought to be the deadliest construction accident in U.S. history.
A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream, to a lower temperature. Cooling towers may either use the evaporation of water to remove heat and cool the working fluid to near the wet-bulb air temperature or, in the case of dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature using radiators.
