44. The schematic diagrams of two suggested designs for a boiling water reactorare shown in the figures. One uses a direct cycle and the other a dual cycle. Theoutlet conditions for both designs are the same. In both designs, steam leaves thesteam 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 thereactor. The vapor is expanded successively in the HPT, the intermediate pressureturbine (IPT), and the low pressure turbine (LPT) before entering the condenserbeing at a 64 mm-Hg. Moisture separators between the HPT and IPT and betweenthe IPT and LPT reduce the steam moisture to 1%; the separated liquid is used toheat the feedwater in an open feedwater heater. The heated condensate and the recirculatedwater from the steam separator are pumped through the reactor. Assume100% efficiency in all pumps, and neglect pressure losses in the moistureseparators. Take all turbine efficiencies as…
