Two-thirds of the energy content of fuel entering a 1,000-MW, nuclear power plant is removed by condenser cooling water that is withdrawn from a local river (there are no stack

losses, as is the case for a fossil fuel-fired plant). The river has an upstream flow of 100 m^3/s and a temperature of 20°C. (a) If the cooling water is only allowed to rise in temperature by 10°C, what flow rate from the river would be required? Compare it to the coal plant in Example 12. (b) How much would the river temperature rise as it receives the heated cooling water?Again, compare it to Example 12.
