← ScienceWhich outcome occurs when compressing Uranium-235 beyond critical mass?
A)Exponentially increased efficiency of fission✓
B)Delayed neutron emission ceases entirely
C)Neutron capture cross-section decreases
D)Spontaneous fusion reaction is initiated
💡 Explanation
Supercriticality causes exponential energy increases because the uncontrolled chain reaction proceeds faster via neutron multiplication. Therefore fission yield increases dramatically, rather than controlled fusion or reduction in neutron availability via capture.
