← ScienceWhich outcome occurs from U-235 enrichment limits in fissile material?
A)Reduced neutron absorption cross-section
B)Accelerated chain reaction propagation✓
C)Increased radiative decay half-life
D)Formation of metastable isomers
💡 Explanation
Increased U-235 enrichment enhances fission probability because, above thresholds for *critical mass*, the neutron flux will achieve *supercriticality*, therefore prompt neutrons accelerate fission faster, rather than a controlled fission like standard reactors' design constraints.
