We  have one right here in San Diego. Sea water is sucked in through pipes, cools down the plant by going in chambers <b>around</b> (not into) the material, then flows back into the ocean. The only change that occurs to that water is that it now returns heated :) Makes for great swimming,(reply>), Iirc San Onofre had a similar cooling solution prior to its shutdown,(reply>), Nothing like pumping super heated water into the ecosystem. I’m sure it is a great benefit to the wildlife.,(reply>), I heard that this is a problem for fish because heating the water deprives it from it's oxygen. But then again it's the sea. It resupplies with the waves. How are the fish there mate?
