Abstract
A three-dimensional time-dependent multigroup SPN method for unstructu red tetrahedral meshes is developed. The SPN equations are expressed i n a canonical form that allows them to be solved using standard diffus ion solution techniques in conjunction with source iteration, diffusio n-synthetic deceleration, and fission-source acceleration. A computati onal comparison of this SPN method with an even-parity S-N method is g iven.
