← ScienceWhich consequence results when xenon-135 builds up excessively during nuclear fission?
A)Reduced neutron flux increases positively
B)Neutron absorption reduces reactor power✓
C)Fuel rod corrosion rate decreases
D)Control rod effectiveness increases linearity
💡 Explanation
Xenon-135 is a strong neutron absorber; therefore, it poisons the reactor via a process called neutron absorption, reducing reactor power because this process decreases the number of neutrons available to sustain the fission chain reaction, rather than accelerating reactions.
