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 cooling water (MW)?
b) How fast does the cooling water need to be pumped to remove this heat (from part a) so that the temperature of the cooling water only increases by 5˚C? The density of water is 1000kg/m3

Thermal pollution in wastewater. A 1000-MW coal-fired power plant with an efficiency of 35% uses water from a neighboring stream (with flow of 75 m3/s and 20°C) to carry away waste heat. About 12% of waste heat goes up in the smokestack; the remaining 88% is taken away by cooling water. (a) Calculate the amount of waste heat (inkWorkJ/s) to be removed by cooling water (b) If the cooling water is only allowed to rise in temperature by 11°C, what...

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...

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...

A typical large coal fired electric power plant produces 1,200MW of electricity by burning fuel with energy content of 3,000 MW. Three hundred and forty (340) MW are lost as heat up the smokestack leaving the rest to drive a generator to produce electricity. However, the thermal efficiency of the turbine is only 45%. That is 45% of the remaining power goes to drive the generator, and 55% is waste heat that must be removed by cooling water. Assume that...

A typical nuclear reactor generates 1,000 MW (1,000 MJ/s) of electrical energy. In doing so, it produces 2,000 MW of “waste heat” that must be removed from the reactorto keep it from melting down. Many reactors are sited next to large bodies of water so that they can use the water for cooling. Consider a reactor where the intakewater is at 18° C. State regulations limit the temperature of the output water to 30° C so as to not harm...

A nuclear power plant produces an average of 3.2x10^3 MW of power during a year of operation. Find the corresponding change in mass of reactor fuel, assuming all of the energy released by the fuel can be converted directly to electrical energy. (In a practical reactor, only a relatively small fraction of the energy can be converted to electricity.)
