This report contains data collected during a series of experiments in the Plutonium Recycle Critical Facility (PRCF) using plutonium and uranium enriched fuel. The experiments were designed to provide a base for assessing the accuracy of calculational techniques used for designing plutonium enriched cores in Boiling Water Reactors with regard to predicting core reactivities, power distributions, and control system worths. Reactivity and power distribution measurements were made in both single region and multiregion loadings. Calorimetric techniques were used to intercalibrate the different fuel types for the multiregion loadings. The reactivity effect of various control blade materials was determined as a function of the prompt neutron decay rate (Rossi-Alpha). Theory-experimental comparisons are based primarily on CNEN developed theoretical models.
