[quote:Anonymous Coward 1324356:MV8xNjA2ODQxXzI2NTU2MDU2X0M3OUZFQTQ4] I don't get the idea we're supposed to be seeing steam...but I'm sure someone else will come along who knows what's what. Article here: http://www.dom.com/about/stations/nuclear/north-anna/waste-heat-treatment-facility.jsp Cooling System The process of generating electricity at North Anna begins with the fission, or splitting, of uranium atoms in the reactor vessel. The vessel is filled with water (not from the lake), which controls, or moderates, the fission process, and removes heat from the reactor core. This water is kept under very high pressure, which prevents it from boiling although it is heated to three times the normal boiling temperature. This hot, pressurized water is pumped to nearby steel containers called steam generators. In the steam generators, the water passes through thousands of small U-shaped tubes — about the diameter of your little finger — transferring its heat to a second, slightly cooler water system. This secondary water becomes steam, which travels through large pipes to spin the turbines in the adjoining building. Spinning at 1,800 RPM, the turbines drive a generator that produces electricity. The steam then is condensed back to a liquid by a third cooling system before it returns to the steam generator to start the process again. The third cooling system's water comes from Lake Anna, and flows through the private WHTF before returning to the lake. [/quote]
