Consider an infinitely large homogeneous mixture of fuel (235U) and a moderating material. Determine the ratio of fuel-to-moderator density, PF/pm, that will render this system critical if the moderating material is graphite (c). = v= Given: Homogeneous mixture of 235U and graphite (C); Data that might be useful Molar weight of fuel (235U), Mp= 235.043929 g/mol; Number of fission neutrons of fuel, v= 2.43 n/fiss; Thermal fission cross-section of fuel, of = 586.7371 b; Thermal radioactive capture of fuel, on = 99.39421 b; 11 2H 12c 160 M[g/mol] 1.0078250 2.0141018 9.0121831 12.000000 15.994915 a [b] 0.3326998 0.0005059 0.0100343 0.0038620 0.0001699 = = The answer is required with 3% of accuracy. The ratio of fuel-to-moderator density is, PF/PM = Number
