| Abstract Scope |
With recent interest in commercializing fusion energy, there is renewed interest in a molten salt blanket with FLiBe to breed tritium and extract heat from the reactor. Relatively little experimental data are available for fusion relevant materials exposed to FLiBe. Prior alloy N and current type 316H steel data are less relevant to fusion. In addition to generating baseline compatibility data at 550°-750°C, the current project focuses on two fusion-specific issues. First, if a beryllide neutron multiplier like Be12Ti were used, how much dissolution would occur and would that affect the compatibility of a reduced activation ferritic martensitic (RAFM) steel like F82H (Fe-8Cr-2W) in the liquid. Current capsule testing for 500 h at 650°C is in progress with F82H and Be-Be12Ti coupons. Second, if F82H contained hydrogen (and/or tritium), would that affect FLiBe compatibility by generating HF or TF. Experiments with H2-loaded F82H also are in progress. |
