Which outcome ultimately dominates after sustained Uranium-235 fission within reactor fuel rods?

💡 Explanation

Fission fragments accumulate, resulting in fission product poisoning via neutron absorption. This is because **neutron capture** reactions increase, therefore reactor criticality reduces at the atomic scale, rather than structural enhancements, neutron reflection changes, or simpler coolant boiling phenomena.
