| Abstract Scope |
An overview of the chemical behavior of nuclear graphite upon exposure to molten fluoride salt is provided. Graphite fluorination, the effect of salt chemistry on surface tension and wetting, and the role of pore size distribution are presented. The role of chemical and physico-chemical interactions between graphite and salt on tritium uptake into graphite and tritium release from graphite are presented. A summary of differences in chemical behavior of nuclear graphite and graphite matrix is provided. Experimental methods for the study of salt-graphite and salt-graphite-tritium interactions are described and possible sources of error and variability in experimental data are discussed. |
