← ScienceWhich outcome occurs when uranium control rods fail?
A)Uncontrolled chain, energy release spikes✓
B)Moderator overheats, reactivity self-offsets
C)Delayed neutron events cease entirely
D)Fission product poisoning improves reaction
💡 Explanation
An uncontrolled chain reaction releases a rapid spike in energy because neutron absorption ceases; therefore, runaway fission results, rather than the moderator simply overheating since negative feedback relies fully upon intact neutron absorbers.
