Which risk increases when neutron absorbent material degrades within a nuclear reactor's control rods?

💡 Explanation

Increased likelihood of uncontrolled chain reaction results because neutron moderation decline leads to a positive feedback loop affecting the fission rate. Therefore, the reactor could become supercritical, rather than maintaining stable operation, because too many neutrons available to propagate fission.
