ABSTRACT: An asymptotic analysis is used to derive a set of diffusion approximations to the nonclassical transport equation with isotropic scattering. These approximations are shown to reduce to the simplified PN equations under the assumption of classical transport, and therefore are labeled nonclassical SPN equations. In addition, the nonclassical SPN equations can be manipulated into a classical form with modified parameters, which can be implemented in existing SPN codes. Numerical results are presented for a one-dimensional random periodic system, validating the theoretical predictions.
