Feed stock prepared from ingot, dingot, and under-saltmelted U was melted by electron bombardment. Analysis of the ingots produced revealed that some Al, Cr, Mg, Mn, and Pb were volatilized from the melt. C was reduced when Zr was present in the feed material. H/sub 2/ and N/sub 2/ also were removed, the latter oniy when there was a relatively high concentration in the feed material. The work indicated the need for very slow melting rates or the casting of large diameter ingots for successful refinement of U. (auth)
