← ScienceWhich risk increases within a reactor if control rod performance degrades?
A)Runaway chain reaction occurs✓
B)Fuel cladding oxidation accelerates
C)Moderator boiling rate diminishes
D)Breeding ratio gradually decreases
💡 Explanation
If control rods fail, neutron absorption decreases; therefore criticality increases due to unchecked nuclear fission. Sustained fission chains cause overheating rather than altered cladding, boiling, or breeding ratios, because control rods regulate reaction rate through neutron flux reduction.
