Does anyone know about Nuclear Power Stations worldwide? I am not looking for specific information just to find out if anyone has heard of them using a "Critical Safety Cooling Water Pipeline" this is a separate water pipeline that is used in event of a meltdown and not the current water supply used to cool the reactor via inlet pipes from the ocean or rivers. I have heard rumours of such a pipe but cannot find anything on web to confirm or deny such a thing?, has anyone heard about this pipe or know of its existance?
