Calculate the fuel utilization and infinite multiplication factor for a fast reactor consisting of a mixture of liquid sodium and plutonium, in which the plutonium is present to 3.0 w/o. The density of the mixture is approximately 1.0 g/cm3 . Assume ? =2.61, ?aF =2.11 barns for fuel (239 Pu), and ?as =0.0008 barns for sodium. Please show work!!!
