Atomic Energy Commission Uranium Enrichment Chart

Description:

This small metal rectangle has nomographic charts engraved on both sides that relate to the process of enriching uranium for use in an atomic reactor. The chart on one side is labeled: NORMAL URANIUM FEED REQUIREMENT. It allows one to find the normal uranium feed required (assuming an assay of uranium that is .711% weight U-235) per kilogram of enriched uranium product, assuming different concentrations of uranium in the tails assay. This side of the chart also has the logo of the Atomic Energy Commission of the United States of America.

The chart on the other side is labeled: SEPARATIVE WORK REQUIREMENT. It allows one to find the amount of separative work required per kilogram of enriched uranium product, given the percentage by weight of uranium in the product and the tails.

A card with the object describes its use. This card and the object fit into a white plastic case.

On the mathematics of nomographic charts, see Lipka.
