Which mechanism dictates neutron production during Uranium-235 enrichment that induces rapid criticality?

💡 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.
