← ScienceWhich byproduct results when neutron moderation lags uranium-235 fission?
A)Increased delayed neutron production rate
B)Elevated undesirable xenon-135 concentration✓
C)Suppressed prompt criticality incidence
D)Enhanced fissile material breeding efficiency
💡 Explanation
Increased neutron absorption causes xenon-135 accumulation because neutron moderation lags, inhibiting further fission via neutron poisoning; therefore xenon increases, rather than neutron production if the moderation operated within design.
