Measurements made with water moderated lattices of slightly enriched uranian rods since the last Geneva conference are presented and discussed. Additional measurements on assemblies having uranium oxide as thee fuel are also presented. Improvements in technique are described and analyzed. The evolution of theoretical methods of interpreting and predicting the neutron behavior of reactor cores of this kind is recounted. The best prssent ways of analyzing the neutron economy and criticality are described and discussed, and compari-sons with the available data are given. The methods range from multigroup treatments based on homogenization to a few group treatments which may be carried out by desk calculator methods. The derivation of the few group parameters from multigroup results is described. The theoretical treatments are supplemented by comparisons with the older four-factor method. Finally, some measurements obtained with plutonium enriched rods are described, and tentative results are given. (auth)
