← ScienceWhich outcome results when Xe-135 builds up reactor?
A)Reduced neutron flux amplitude✓
B)Increased fuel cladding corrosion
C)Elevated coolant boiling point
D)Enhanced energy extraction uniformity
💡 Explanation
Reactor poisoning occurs because Xe-135 strongly absorbs neutrons, reducing neutron flux amplitude and reaction rate. Therefore, power decreases rather than increasing, because neutron multiplication is essential for sustaining controlled nuclear fission.
