← ScienceUranium enrichment increases neutron initiation probability; which event occurs?
A)Sustained nuclear chain reaction begins✓
B)Faster beta decay of isotopes
C)Increased production of alpha particles
D)Greater isotopic chemical reaction affinity
💡 Explanation
Increased U-235 concentrations undergoing induced fission raises neutron flux density initiating more fissions; because neutron multiplication exceeds losses. Therefore, a spreading chain reaction occurs, rather than simple beta/alpha decay or different chemical properties.
