Abstract: Chemical and physical data on twenty binary uranium compounds that may prove suitable for refractory nuclear fuels were assembled. The compounds were those with aluminum, boron, carbon, iron, nickel, nitrogen, silicon, or sulfur. Too little is known at this time about the compounds to evaluate any of them for fuel. The program is being extended in an effort to provide the needed data.

Discussing the investigation and ore reserve estimation of the Barlow Creek Roscoelite deposits with ore reserve data Grayskull and Lightner Creek areas, Colorado.

A short survey of some of the metabolic relationships of the elements, cerium, colurbium, plutonium, strontium, yttrium, and zirconium is presented. While the results of internally deposited radium have not been investigated in these experiments, they have been extensively studies by others. Because so much is known of its biological effects, it has been included in this historical survey.
