If a one cubic centimeter section of a reactor has a macroscopic fission cross section of 0.954 cm ¹1, and if the thermal neutron flux is 2x1015 n/cm² s, what is the fission rate in that cubic centimeter? A reactor operating at a flux level of 3.15 x 1012 n/cm²-sec contains 2.5x1018 atoms of U-235 per cm³. The reaction rate is 1.3 x 10¹2 fission/cm³. Calculate Σ, and of. Express the answers in cm¹ and barns. How many collisions are required to slow a neutron from an energy of 3.12 MeV to a thermal energy of 0.88 eV, using a moderator with = 0.889. If the average fractional energy loss per collision in a material is 0.82, what will be the energy of a 2.65 MeV neutron after (a) 4 collisions? (b) 10 collisions?
