Which risk increases when heavy water acts without control rods as the moderator in a nuclear fission reactor?

💡 Explanation

Uncontrolled fission without control rods will experience criticality because neutron multiplication and subsequent fission events accelerate exponentially due to uninhibited neutron moderation. This runaway chain reaction increases reaction rates, rather than ineffective moderation; thus a criticality accident results.
