5. For the following neutron life cycle, calculate the fast fission factor, fast non-leakage probability, resonance escape probability, thermal non-leakage probability, thermal utilization factor, reproduction factor, and ker. [14 pts] 1000 fast (thermal fission neutrons) 20 fast (fast fission) neutrons 40 fast neutrons lost by leakage 120 neutrons absorbed in U-238 80 thermal neutrons lost by leakage 302 thermal neutrons absorbed in points, moderator, and core materials 75 thermal neutrons undergoing nonfission capture in U-235 and U-238 1006 fast neutrons are produced by thermal fission to start the next generation
