← ScienceWhich outcome occurs within a nuclear reactor when control rods are fully removed?
A)Neutron moderation decreases exponentially.
B)Fission reactions increase exponentially.✓
C)Gamma radiation emission decreases.
D)Coolant temperature stabilizes immediately.
💡 Explanation
Withdrawn control rods reduce neutron absorption; the increase in neutron population generates more uranium fission events because the neutron multiplication factor rises above 1, therefore self-sustaining exponential growth becomes possible, rather than controlled reaction rates.
