Which outcome is likely, immediately after sustained nuclear fission within a reactor is halted?

💡 Explanation

Decay heat will induce coolant boiling, because energy from fission product decay continues even with neutron moderation stopped with control rods, therefore continued heat rather than reactivity or contraction occurs after chain maintenance ends.
