A nuclear power plant based on the Rankine cycle operates with a boiling-water reactor to develop net cycle power of 3 MW. Steam exits the reactor core at 100 bar, 52O degree C and expands through the turbine to the condenser pressure of 1 bar. Saturated liquid exits the condenser and is pumped to the reactor pressure of l00 bar. Isentropic efficiencies of the turbine and pump are 81% and 78%, respectively. Cooling water enters the condenser at 15 degree...
A power plant operates on the Rankine cycle and uses a nuclear reactor to generate the steam that enters the turbine
A power plant operates on the Rankine cycle and uses a nuclear reactor to generate the steam that enters the turbine. The condenser receives cooling water from a chiller and discharges the used water to a nearby lake. Kinetic and potential effects are negligible. Stray heat transfer from the turbine, pump, and condenser can be neglected. Data are provided in the table for the system operating at steady state.

A combined cycle power plant consists of two gas turbines; cach produces a net power of 160 MW, and a 70 MW steam power cycle. The combustion of the fuel in the combustion chamber produces hot gases at 1400°C. The hot gases leaving the gas turbines are used to generate steam through the heat recovery steam generator (Boiler). The hot gases enter the heat recovery steam generator at 880°C and leaves at 660°C. Water enters the isentropic pump as saturated...

A power plant using a Rankine power generation cycle and steam operates at a temperature of 80 oC in the condenser, a pressure of 2.5 MPa in the boiler, and a maximum boiler temperature of 700 oC. Draw the two cycles described below on a temperature-entropy diagram for steam, and answer the following questions. a) What is the efficiency of this power plant, assuming the pump and turbine operate adiabatically and reversibly? What is the temperature of the steam leaving...

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...
