Which mechanism causes increased neutron multiplication during supercritical reactor conditions?

💡 Explanation

Void formation leads to reduced moderation and absorption; increased fuel density causes more fission events. This is because decreased neutron absorption enhances the fission chain reaction, therefore neutron multiplication increases, rather than if Doppler broadening reduces reactivity.
