Measurements on an experimental fast reactor fueled by 239Pu and 238U show that, for every 100 fast neutrons emitted in fission, 5 of them are escaped from the reactor. Rest of the neutrons are absorbed in the reactor by structural, fissile and fertile materials. Of those absorbed neutrons, 90% are absorbed in fissile and fertile materials. If the conversion ratio is equal to 1.07, determine the neutron multiplication factor k. [Note: The values of 239Ca = 2.5 barn, 239of = 2.2 barn, 239v = 2.5 and 2380a = 1.9 barn, 238of = 0.4 barn, 238v = 2.52]
