Carry out a rudimentary design of a small modular nuclear reactor which delivers 100 MWe (megawatt electric). The reactor is based on a Rankine cycle where the steam is expanded in a turbine from 12.5 MPa and 350o C to 5 kPA. Assuming that the electric generator is 98% efficient. The actual cycle achieves 90% of the efficiency of the corresponding ideal cycle. 90% of the fission energy goes to coolant (Gf =180 Mev/fission). Find (a) If the reactor uses the uranium as the fuel and the enrichment is 3% of U-235. What mass of fuel rod (UO2) is consumed each year ? (b) What is the flow rate of steam in kg/s required when the reactor is running at full power ? Note : Assume that the BW γ is the same for the real and ideal cycles and the pump has an efficiency of 90%.
