A description of ZPR-III Assembly 41 and some of the experiments performed with it, along with the primary details of the fast exponential and the fast-thermal critical system are given. Experiments with steel and aluminum reflectors in the assembly blankets are reported, and their results are compared with reflector savings measurements on the fast exponential and to theoretical calculations. Fission ratios obtained in the three 5 to1 systems are compared, as well as central reactivity coefficients from the two critical studies. Experiments concerned with the conversion of uranium-238 to plutonium in EBR-II type blankets are described.
