A nuclear power plant has an electrical power output of 1000 MW and operates with an efficiency of 33%. If the excess energy is carried away from the plant by a river with a flow rate of 1.4e6 kg/s, what is the rise in temperature of the flowing water? Hint: Consider the flow of energy during one second. During that second, the power plant does 1000 MJ of work ?. Knowing the work and the efficiency, you can calculate the excess heat ?? which is generated during that second. This excess heat goes into the river, heating up the water. You are given how many kg of water passes by each second. You need to calculate how much the excess heat raises the temperature of that much water, using the specific heat of water.

30% of the energy produced from a nuclear power plant is converted to 1000 MW of electrical energy. The remaining 70% of the energy from this plant is converted to heat waste. 20% of the heat waste is released out of the smokestack. 80% of the heat waste is taken away by cooling water that is drawn from a nearby river. Specific heat of water = 4.184 kJ/kgºC a) How much of the heat waste is taken away by the...

A nuclear power plant generates 3000 MW of heat energy from nuclear reactions in the reactor's core. This energy is used to boil water and produce high-pressure steam at 320 ∘C. The steam spins a turbine, which produces 1000 MW of electric power, then the steam is condensed and the water is cooled to 25∘C before starting the cycle again. Part A: What is the maximum possible thermal efficiency of the power plant? Part B: Cooling water from a river...
