← ScienceWhich outcome arises when induced fission achieves criticality?
A)Sustained chain reaction occurs✓
B)Neutron emission ceases entirely
C)Fuel enrichment becomes unnecessary
D)Alpha decay rates accelerate acutely
💡 Explanation
A sustained chain reaction arises from criticality, because increased neutron production causes continuous fission events. Therefore, fission self-propagates, rather than halting as criticality hasn't been achieved and controlled by neutron absorbers.
