Some simple models for criticality problems are reviewed. The emphasis is on fast systems with moderating reflectors. Albedo and multigroup albedo models for fast cores with moderating reflectors are described. Comparisons with experiment are made for U/sup 235/ and Pu/sup 235/ cores with reflectors of water and graphite. A model for calculations on the interaction of mixed assemblied of fast and thermal cores is described and results are compared with experiment. An outline is then given of some unusual models under development. Preliminary results are encouraging. A generalization of diffusion theory takes into account the size of the system. Two novel models for reactor calculations are described-- the shell and the neutron traffic model. A composite model based on generalized diffusion theory and the neutron traffic model is then described. (auth)
