Power plant condenser, cooled by seawater

Internal Cathodic Protection of a Power Plant Condenser Cooled by Seawater... 

Marine Crustacea, which include barnacles and crabs and the marine molluscs, which include mussels, can cause severe fouling problems when coastal seawater is used for once-through cooling of power plant turbine condensers. Various species of marine barnacles, mussels, and their spat quickly establish in warm waters and become extremely troublesome. (The problems are exacerbated by seaweed, sponges, various other marine organisms, and SRBs.) The marine acorn (or rock) barnacle, of group Cirripedia, is a common marine foulant, as are the mussels of family Mytillidae. 

The water used in the condensers to cool the steam is drawn from the sea. At Barseback, each reactor unit uses 2S cubic meters of seawater per second, which is pumped into a channel leading into the power plant. When the cooling water is returned to the sea In the Oresund Strait, It Is 10 C warmer than when It entered the plant. The seawater is pumped through the condenser in a special system of tubes. It never comes into contact with the steam produced by the reactor.
