← ScienceWhich outcome occurs when high neutron flux activates control rod isotopes?
A)Neutron absorption decreases chain reaction✓
B)Fuel enrichment increases localized criticality
C)Gamma radiation induces structural failure
D)Thermal expansion prevents coolant circulation
💡 Explanation
Neutron absorption in control rod poisons involves induced radioactivity, capturing neutrons, because the transmutation increases the absorption cross-section. Therefore, neutron flux drops; rather than core overheating resulting from positive reactivity, control rod isotopes mitigate runaway criticality.
