ZPR-9 Assemblies No. 6-9 Critical Experiments

A series of fast critical assemblies was studied in the Argonne ZPR-9 facility in support of the Laboratory's design effort in the fast reactor, nuclear-propulsion program. Historically, critical experiments have been used to provide engineering design parameters for a mockup or prototype reactor. This approach was neither practical nor desirable in the rocket program since the engineering work was done essentially simultaneously with the physics effort. Rather, an attempt was made primarily to provide integral measurements as checkpoints for cross-section sets that were generated for the program and, secondarily, to provide data to test the utility of simple, one-dimensional, multigroup diffusion theory in the program. A major objective of the present report is to present the results of a series of critical experiments emphasizing the important differences between measurements made in metal- and oxide-fueled cores and between aluminum, Al2O3, and BeO as a reflector material. This is the third of four topical reports describing a two year program of study.
