Which process increases when heavy isotopes accumulate in uranium fuel rods?

💡 Explanation

Neutron absorption increases because specific isotopes formed during fission reactions (e.g., Xenon-135) exhibit a high neutron capture cross-section; therefore, these isotopes reduce the number of neutrons available for sustaining the chain reaction rather than accelerating it.
