A typical nuclear reactor generates 1000 MW of electrical energy. In doing so, it produces "waste heat" at a rate of 2000 MW and this heat must be removed from the reactor. Many reactors are sited next to large bodies of water so that they can use the water for cooling. Consider a reactor where the intake water is at 17 degress C. State regulations limit the temperature of the output water to 30 degrees C so as not to harm aquatic organisms.
How many kilograms of cooling water have to be pumped through the reactor each minute?
