An investigation is conducted regarding the equivalent-cell assumption, used in reactor calculations. We calculate the thermal utilization using the real cell shape and allowing absorption in the moderator. The results show that for heavy water and graphite lattices, the correction due to the equivalent-cylindrical-cell assumption is of the same order of magnitude as the correction due to the neglect of absorption in the moderator.
