The outstanding problems and work areas necessary for proper application of heterogeneous reactor calculation methods are listed. The self-consistent equations are foi mulated for a thermal reactor with significant non-thermal fissions. Equations for calculating the effects of resonances on the slowing down kernels are given. The moderator absorption is expressed in terms of the rod absorptions. This relation is used to calculate the thermal utilization and resonance escape probability for the reactor. The resulting formulas can be used to obtain these two quantities for lattices with different types of rods and this provide the necessary input for approximate homegenoeus calculation of these systems. Various methods are considered for determining values of some of the rod parameters which are needed in a heterogeneous calculation. (W.D.M.)
