Ames National Laboratory is a government-owned, contractor-operated national laboratory of the U.S. Department of Energy (DOE), operated by and located on the campus of Iowa State University in Ames, Iowa.

For more than 70 years, the Ames National Laboratory has successfully partnered with Iowa State University, and is unique among the 17 DOE laboratories in that it is physically located on the campus of a major research university. Many of the scientists and administrators at the Laboratory also hold faculty positions at the University and the Laboratory has access to both undergraduate and graduate student talent.

Abstract

The extraction of plutonium from molten uranium with immiscible molten metals, silver, lanthanum and cerium, has been investigated. A facility is described in which these experiments on uranium containing 0. 2% plutonium were conducted safely. The distribution coefficients and efficiency of removal from uranium were determined for silver and lanthanum at several temperatures in the range 1175-1375° C and for cerium at 1225o C.
