A nuclear power plant is rated at 500 MW (it provides this amount of useful power). During operation, the hot core is at 577 C, and the average temperature of the cooling water is 27 °C. This plant is rated at the lower efficiency of 50%. For cooling, it takes in seawater at 17 °C and gives it back at 37 °C (so that the average is indeed 27 °C ). How many kilograms of water is needed per second?
