← ScienceWhich process causes increased neutron production within a nuclear reactor core?
A)Nuclear fission chain reaction diverging✓
B)Moderator density dropping sharply
C)Accumulation of xenon-135 byproduct
D)Control rod insertion being impeded
💡 Explanation
A divergent nuclear fission chain reaction increases neutron production because the mechanism of stimulated fission overwhelms neutron absorption; therefore more neutrons bombard fissile material, rather than control rods consuming/reducing the existing neuron population.
