← ScienceWhich energy outcome occurs when the control rods fail in a nuclear reactor?
A)Uncontrolled nuclear chain reaction occurs✓
B)Gamma radiation exposure decreases sharply
C)Coolant temperature remains relatively stable
D)Radioactive waste production temporarily stabilizes
💡 Explanation
When control rods fail, neutron absorption decreases substantially. This loss accelerates nuclear fission reactions via a self-amplifying process called positive feedback; because heat production corresponds with reaction rate, reactor temperature increases uncontrollably—rather than stabilizing, neutron flux will quickly exceed design limits.
