Cooling water: a source of conflict in Spain, 1970-1980

Abstract

Water resources are limited and uneven in space and time. Competition for the use of the resource can lead to conflicts between water users. Besides its use for irrigation and agriculture, water is an essential input in the thermoelectric power generation process. Massive Spanish nuclear program projects have conditioned water management in the country, as significant freshwater volumes need to be constantly available for the proper operation of these facilities. Water for cooling has conflicted with other water-using activities, resulting in regional imbalances. The present study shows that cooling water represented a source of conflict between irrigators and electricity companies in Spain in the 1970s and 1980s. A historical analysis of documentary sources reveals that the drawing off of fresh water for cooling by the nuclear industry was one of the many causes of frequent disputes and the rise of social movements against the installation of nuclear power plants in Spain during that period.
