EXTENSION OF THE SAFE GEOMETRIC PARAMETERS TO SLIGHTLY ENRICHED URANIUM
Use is made of a method of buckling comparisons to extend the safe geometric criticality parameters of the infinite cylinder, infinite slab, and the sphere, to U of enrichments between 0.72 and 5% U/sup 235/ assays. The new criteria complete the determination of the assay variation of these safe parameters and permit their tabulation for U of all enrichments. Comparison with the available experimental data which include results of the Hanford Physical Constants Testing Reactor, together with previous ORGDP studies based on the Water Boiler Theory, indicates that the new criteria may be safely applied to the U systems normally encountered in gaseous diffusion plant operations.
