← ScienceWhich risk escalates if a nuclear fuel rod's cladding becomes porous?
A)Increased parasitic neutron absorption
B)Heightened probability of prompt criticality
C)Reduced moderator effectiveness locally
D)Elevated xenon-135 fission product poisoning✓
💡 Explanation
Fission product poisoning increases because the porous cladding allows xenon-135 to escape the fuel matrix into the coolant. This process, called neutron absorption, lowers reactivity. Therefore, fission product poisoning increases rather than the neutron's effectiveness decreasing.
