In applying nodal procedures to fast reactor problems, it was found that a generalization of the modified coarse mesh diffusion method led to particularly good results for a variety of cases. That modification involved use of different interpolation parameters in different types of nodes. Empirically, it was found that best results were obtained when these parameters were negative. This paper introduces a procedure which provides a consistent theoretical basis for the types of parameters found empirically to give good results. The procedure is based on preservation of reflection by the node, and will be referred to as reflection-based coarse mesh theory (RBCMT).
