Which risk increases when enriched uranium isotopes encounter supercritical water?

💡 Explanation

Accelerated neutron moderation occurs because hydrogen in supercritical water readily thermalizes neutrons, increasing the fission rate in the enriched uranium via neutron capture; therefore a runaway chain reaction risk increases, rather than stable nuclear decay.
