← ScienceWhich outcome results when a pressurized water reactor experiences coolant voiding?
A)Increased neutron moderation and thermalization
B)Positive feedback in nuclear reaction✓
C)Decreased fuel rod cladding temperature
D)Stable reactor power due to density
💡 Explanation
A loss of coolant means less neutron absorption; therefore, the neutron multiplication factor increases via positive void coefficient reactivity feedback because water, rather than another moderator, is absent, rather than power staying constant if density were uniform across phases.
