The authors would like to acknowledge the many discussions regarding the QS Process they had with Professor Paul E. Queneau of Dartmouth College during the inception of this project. This work was supported in part through research grants provided by the University of Utah Mineral Leasing Fund and the State of Utah through the State Center of Excellence for Advanced Pyrometallurgical Technology. During the course of this work, KMI was also supported in part by a University of Utah Graduate Research Committee Fellowship and a Geneva Steel Fellowship. REFERENCES 1. H.K.

Interactions between Drops of a Molten Aluminum-Lithium Alloy and Liquid Water LLOYD S. NELSON, PATRICIA M. DUDA, and DAVID A. HYNDMAN In certain hypothesized nuclear reactor accident scenarios, 1- to 10-g drops of molten aluminum-lithium alloys might contact liquid water. Because vigorous steam explosions have occurred when large amounts of molten aluminum-lithium alloys wer
