Critical Parameter for Spatially Inhomogeneous Slabs

Nuclear Science and Engineering, 1982
The critical problem in a finite plane slab is studied by an appropriate extension of the integral transform method. For a given optical thickness, the value of the scattering ratio (or mean number of secondaries per collision) that makes the system critical is determined as an eigenvalue of a Fredholm integral equation, in which a continuous position ...

A fictitious slab with vanishing critical thickness

Transport Theory and Statistical Physics, 1978
Abstract In one-speed neutron transport theory, it is shown that a fictitious anisotropic fission and scattering kernel with an extreme forward bias would give a critical slab thickness varying non-monotonically with anisotropy. For this particular kernel, the critical thickness increases first with increasing forward bias but decreases later and ...

On the Critical Reactor Problem for a Reflected Slab

Nuclear Science and Engineering, 1975
AbstractThe elementary solutions of the one-speed transport equation are used, along with certain invariance principles, to establish tractable solutions to reflected reactor critical problems in plane geometry.
