Which risk increases when enriched uranium isotopes accumulate in reprocessing equipment?

💡 Explanation

An uncontrolled nuclear chain reaction becomes a risk because the increased concentration of fissile isotopes enhances the probability of neutron-induced fission events; therefore, criticality accidents occur, rather than only isotopic decay common at lower concentrations.
