← ScienceWhich outcome occurs when enriched uranium-235 accumulates in containment?
A)Neutron multiplication creates supercriticality✓
B)Moderator poisoning delays initiation
C)Cladding oxidation accelerates corrosion
D)Doppler broadening reduces absorption
💡 Explanation
Neutron multiplication leads to a supercriticality event because a runaway chain reaction accelerates due to the increasing availability of fissile isotopes. Therefore, criticality occurs, rather than delayed initiation or moderation changes.
