The schematic diagrams of two suggested designs for a boiling water reactor are shown in the figures. One uses a direct cycle and the other a dual cycle. The outlet conditions for both designs are the same. In both designs, steam leaves the steam separator assembly with a quality of 95% to enter the high pressure turbine (HPT) while the saturated liquid with 95 weight percent being recirculated to the reactor. The vapor is expanded successively in the HPT, the intermediate pressure turbine (IPT), and the low pressure turbine (LPT) before entering the condenser being at a 64 mm-Hg. Moisture separators between the HPT and IPT and between the IPT and LPT reduce the steam moisture to 1%; the separated liquid is used to heat the feedwater in an open feedwater heater. The heated condensate and the recirculated water from the steam separator are pumped through the reactor. Assume 100% efficiency in all pumps, and neglect pressure losses in the moisture separators. Take all turbine efficiencies as 75%. In the dual cycle design, an additional steam generator is used. The 6.6 MPa saturated liquid from the steam separator produces saturated steam at 3.4 MPa in the secondary steam generator, its enthalpy being reduced to 1163 kJ/kg. The 3.4 MPa steam is introduced to the HPT at the appropriate stage with perfect mixing. Sketch the T-s diagram for the direct and dual cycles.
