| Abstract Scope |
The objective of this study is to evaluate the fission product effects and performance implications in Tistructural-isotropic (TRISO) particles. TRISO fuel particles serve as the fuel elements in the high temperature gas reactor (HTGR). At high burnup, fission products are produced and accumulate in these fuels. The carbide layers (buffer, IPyC, SiC, and OPyC), which encase the uranium-based fuel kernels in these TRISO particles, are meant to accommodate swelling, provide structural integrity, and to prevent fission product escape. Work done at the Extreme Environment Materials Laboratory is aimed at evaluating the fission product accumulation and accommodation in the TRISO fuel kernel and the buffer layer as well as fission product degradation and the performance implications of TRISO carbide layers through diffusion couple experiments and electron microscopy microstructure characterization. |
