Material Selection Considerations for Fluoride Thermal Energy Storage Containment in a Sodium Heat Pipe Environment.

摘要

This contract involved a literature survey to determine the state-of-the-art of materials in a high temperature Na and vacuum environment as applied to thermal energy storage. It was found that little information exists for materials or heat pipes in the high temperature (1400 K) Na or vacuum environments. Program recommendations are to perform life tests on candidate materials and Na heat pipes with post test corrosion analyses. Na wicking parameter must be determined experimentally for accurate heat pipe design. (Author)
