← ScienceWhich outcome occurs when a nuclear reactor's moderator degrades?
A)Increased neutron absorption
B)Elevated core temperatures result✓
C)Decay heat drastically decreases
D)Control rod effectiveness dramatically amplified
💡 Explanation
Degradation reduces neutron moderation, causing fission reactions to accelerate rather than slowing down. Energy increases because the chain reaction escalates via neutron thermalization, therefore core temperatures increase rather than decreased heat or modulated neutron absorption.
