← ScienceWhich mechanism dictates neutron production during Uranium-235 enrichment that induces rapid criticality?
A)Increased neutron flux by moderation✓
B)Augmented electron capture cross-section
C)Decreased gamma-ray absorption ratios
D)Elevated spontaneous radiative decay rates
💡 Explanation
Increased neutron flux enhances uranium criticality from nuclear fission because moderation reduces neutron speed therefore increasing fission cross-section rather than electron or gamma interaction which do not contribute to maintaining that nuclear chain.
