Which consequence results when enriched uranium isotopes accumulate in molten salt reactor coolant?

💡 Explanation

Elevated criticality risk occurs because neutron absorption increases with more fissile isotopes initiating uncontrolled chain reactions; therefore, the reactor power can surge rather than remain stable, since other factors like control rod positions become less effective.
