A two-dimensional, two-group albedo model is developed for replacement of a pressurized water reactor reflector. Spatially dependent albedos in the vicinity of an outward concaving corner of the core boundary are derived using the same formulation and technique developed by the authors for the theory of the interface flux nodal method. The model is mathematically simple and has been successfully tested for applications in both fine-mesh finite difference and coarse-mesh nodal calculations, for cases of a reflector with and without a shroud.
