← ScienceWhich outcome accelerates when neutron moderation decreases in a reactor core?
A)Chain reaction criticality increases✓
B)Xenon-135 poisoning decreases
C)Coolant boiling heat transfer improves
D)Fuel rod cladding corrosion decreases
💡 Explanation
A slowed neutron moderation decreases the probability of neutron capture by Uranium-235, initiating nuclear fission. Because the chain reaction criticality will increase, therefore, leading to a faster reaction rate and heat production, rather than poisoning reduction, heat transfer improvement or corrosion going down.
