← ScienceWhich outcome increases when neutron multiplication reaches criticality in fissile material?
A)Delayed neutron precursor concentration decreases
B)Fission fragment kinetic energy distribution increases✓
C)Rate of spontaneous fission increases
D)Control rod neutron capture cross-section falls
💡 Explanation
Kinetic energy produced increases because criticality leads to a sustained, exponentially increasing number of fission events, quickly releasing excess kinetic energy, otherwise the reaction would dampen. Increased precursor decay does not release energy, rather than affecting kinetic energy or changing control-rod absorption, which maintains stable fission reactions.
