Which risk increases within a PWR containment when control rods fail?

💡 Explanation

Uncontrolled fission elevates the risk of a runaway chain reaction, because neutron moderation continues unhindered; therefore, reactivity increases rather than diminishing, due to the failure of neutron absorption by control rods.
