← ScienceWhich outcome occurs when enriched uranium, specifically uranium-235, sustains radiative capture?
A)Increased probability of subsequent fission✓
B)Isotopic enrichment of Uranium-238 rises
C)Neutron moderation becomes less effective
D)Chain reaction self-termination accelerates
💡 Explanation
A uranium-235 nucleus absorbing a neutron initiates nuclear fission because neutron capture changes the nucleus’ properties, rendering it unstable, therefore fission probability increases rather than altering the broader isotopic composition or dynamics.
