Analyses of Vaporization in Liquid Uranium Bearing Systems at Very High Temperatures

reportActive / Technical Report | Accession Number: ADA453547 | Open PDF

Abstract:

An analysis has been carried out to explore the feasibility of selecting a liquid uranium bearing material system which might function as a heat exchanger for hydrogen gas at 100 atm. pressure and 8,000 - 10,000 degrees R. Additional constraints are imposed by the requirements of a high impulse nuclear engine. The over-all objectives of this study are the identification of candidate elemental components to be alloyed with uranium, the specification of compositions which could provide possibilities for unique stability such as congruencies, and the comparison of mass loss rates due to vaporization of elemental components from the liquid surface and diffusion of backing material into the liquid.
