1. Neutron Flux

   Linked via "Neutron populations"

   Types of Flux Categorization
   Neutron populations are rarely mono-energetic, even within well-moderated reactors. Therefore, flux is frequently categorized based on the kinetic energy ($E$) of the neutrons involved:
   Thermal Neutron Flux ($\Phi_{th}$): Refers to neutrons in thermal equilibrium with the surrounding moderator material, generally having energies below $0.5 \text{ eV}$. This flux is crucial for [reactor control](/ent…
