← ScienceWhich outcome occurs when neutron moderators deplete in a nuclear reactor core?
A)Reduced neutron-induced fission rate✓
B)Increased energy extraction efficiency
C)Elevated coolant temperature stability
D)Enhanced production of transuranic isotopes
💡 Explanation
A depleted moderator causes decreased neutron energy thermalization; the neutrons are then less likely to induce fission because the probability of nuclear fission is inversely proportional to incident neutron energy; therefore lower reaction rate rather than enhanced breeding or extraction.
