Lecture
This lecture covers media containing fuel, the diffusion equation for thermal reactors, large reactors, analytical solutions for the reactor equation, and thermal non-leakage probability. It also discusses the fast and thermal neutron sources, the steady-state diffusion equation for thermal neutrons, and the Fermi age theory. The lecture delves into the criticality condition, reactor equation, and the migration area. Additionally, it explores the analytical solutions for spherical, rectangular parallelepiped, and cylindrical reactors. The concepts of non-leakage probability for thermal and fast neutrons are thoroughly explained.
