(b) Thermal neutrons have a fission cross-section of 583 b for 235 U. Each fission of 335 U produces, on average, 2.44 fast neutrons. The thermal cross-section of non-fissionable pro- cesses for 335 U is 99 b. What is the mean number of fast neutrons produced by 325U per incident thermal neutron? {3}
