← ScienceWhich outcome occurs when a reactor uses unenriched uranium fuel?
A)Lower power output, shorter operational cycle✓
B)Increased probability of core meltdown
C)Higher neutron flux and fuel consumption
D)Elevated levels of radioactive waste generation
💡 Explanation
Lower power output and a shorter operational cycle occur because neutron moderation relies on isotopic abundance and the neutron absorption cross-section of U-235; therefore, the chain reaction is less efficient rather than leading to meltdown.
