← ScienceWhich outcome occurs when a control rod becomes stuck *partially* withdrawn in a nuclear reactor?
A)Delayed neutron flux remains elevated✓
B)Reactor temperature fluctuates in damped oscillations
C)Fission products undergo spontaneous transmutation
D)Moderator density shifts to vapor phase
💡 Explanation
The reactor power increases steadily because the cadmium in the control rod cannot fully perform neutron absorption efficiently, causing a delayed neutron flux surge due to increased fissions; therefore power rises, rather than damping or transmutation under correctly functioning conditions.
