Which risk increases when enriched uranium isotopes separate thermally?

💡 Explanation

When lighter isotopes preferentially vaporize during thermal separation, the remaining material enriches with heavier, more fissile isotopes; neutron multiplication increases because fission probability rises, therefore potentially causing accidental criticality rather than stable operation.
