Which consequence results when fuel enrichment decreases in a critical fission reactor?

💡 Explanation

Decreasing enrichment reduces the concentration of fissile isotopes; the chain reaction relies on neutron collisions, so reduced fissile material slows the rate of the **neutron transport** because fewer fissile nuclei are present to absorb energy, therefore lowering neutron flux rather than raising heat output.
