Abstract Scope |
Graphite is the most commonly proposed moderator material for thermal-spectrum molten salt reactors (MSRs). Due to the porosity of graphite, salts can infiltrate into the moderate blocks, causing structural degradation and, potentially, critically hot spots. By exposing selected graphite grades to FLiNaK salt with controlled chemistry and pressure, the effect of material and salt variables can be determined. In this study, the effects of time, temperature, pore size, and pressure on fluoride salt infiltration into graphite are analyzed. This study reports on recent experiments aimed at identifying the optimal graphite grade use in the Molten Salt Research Reactor to be built at Abilene Christian University and discusses the impact of the findings for fluoride-based MSRs in general. |
