Which outcome dramatically lowers the necessary critical mass in reactor design employing neutron moderation?

💡 Explanation

Increased neutron flux and chain reaction lowers critical mass due to neutron moderation raising fission probability because thermal neutrons are more readily captured by uranium-235 therefore requiring less fissile material rather than fuel depletion or structural damage.
