Abstract Scope |
The United States Department of Energy (DOE) has extensive research and development experience in sodium-cooled fast reactor technologies, such as the Experimental Breeder Reactor-II (EBR-II) and the Fast Flux Test Facility (FFTF). Specifically, metal fuels were used as driver fuel and tested under both steady-state and off-normal reactor conditions, which demonstrated excellent fuel performance with a large safety margin. To improve understanding of metal fuel performance under steady state and transient conditions and address the current industry needs for fuel qualification, the DOE's Office of Nuclear Energy Advanced Fuel Campaign is now carrying out post-irradiation examination (PIE) and post-testing characterization of irradiated legacy metal fuel specimens from EBR-II and FFTF. This presentation will discuss our progress in characterization of metal fuel in extreme radiation environment through a combination of post mortal and in-situ techniques. |
