Which risk increases sharply when neutron moderators are lost in a nuclear reactor core during fission?

💡 Explanation

Fuel overheat risk increases due to decreased control of the **neutron flux**, because the rate of collisions declines drastically, driving up the number of neutrons absorbed by the uranium directly therefore escalating the production of heat, rather than a controlled fission which can continue safely in stable and cooled conditions.
