This report is a summary of the current status of the fused salt systems which have been under study in the ANP Chemistry Section during the last several vears. The inclusion of a phase equilibrium diagram in this report is not an indication that it represents a finished study. It has been necessary to minimize the emphasis on several systems as it became clear that these systems promised small returns to the ANP fuels program. Discussions regarding the extent of the study and phase characteristics of each of these systems are to be found in the references listed in the Table of Contents. A large number of people have contributed to an under- standing of these phase relationships. A partial list of major contributors to these studies includes C. J. Barton, F. ¥. Blankenship, L. M. Bratcher, V. 8. Coleman, H. A. Friedman, H. Insley, B. 8. Landau, T. N. McVay, R. E. Moore, R. F. Newton, B. J. Sturm, J. Truitt, G. D. White, and W. C. Whitley.
