← ScienceWhich consequence results when critical-mass uranium-235 exceeds structural containment?
A)Uncontrolled nuclear chain reaction ensues✓
B)Enriched uranium reverts to ore
C)Isotopic decay accelerates exponentially
D)Binding energy reaches minimum threshold
💡 Explanation
An exceeding structural containment causes uncontrolled rapid fission because neutron multiplication exceeds control limits resulting in a runaway chain reaction; therefore, nuclear fission will occur rather than stable decay and isotope ratios remain constant.
