Background information and definitions
Once-through cooling systems use a process that involves pulling in cold water from rivers, lakes, or the ocean to cool power plant reactors. Marine or freshwater mammals may be drawn into the intake tunnels and become trapped resulting in injury or death. An alternative approach is to use cooling towers in which water is stored in large tanks and re-used.
