Which risk increases within a reactor if control rod performance degrades?

💡 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.
