A three-dimensional time-dependent multigroup SP{sub N} method for unstructured tetrahedral meshes is developed. The SP{sub N} equations are expressed in a canonical form that allows them to be solved using standard diffusion solution techniques in conjunction with source iteration, diffusion-synthetic acceleration, and fission-source acceleration. A computational comparison of this SP{sub N} method with an even-parity S{sub N} method is given.
