A nuclear reactor power plant utilizing water as the working fluid is shown schematically below. The high-temperature compressed liquid from the reactor is throttled into the flash evaporator. That fraction of the water that flashes into vapour flows to the turbine, while that which remains liquid flows to the mixing chamber. Determine the exergy of the water (with respect to the surroundings) leaving the reactor. Use an ambient temperature of To = 290K and ambient pressure of po = 0.1MPa.
