| Abstract Scope |
Traditional tristructural-isotropic (TRISO) fuel particles are made of uranium oxide or uranium oxide/uranium carbide kernel coated with three layers of pyrolytic carbon (PyC) and one of silicon carbide. TRISO and other coated particle fuels have been proposed for future microreactor designs for terrestrial use and space exploration. This expanded service envelope will require in some cases the use of coated particle fuels with different kernel sizes and compositions, as well as different coating layers, thicknesses and compositions. In this work we will discuss the challenges and limitations associated with the fabrication of coated particle fuels with new configurations as well as new tools to accelerate their development. This will include the use of additives for the fabrication of kernels, the use of new gas precursors for coatings as well as the use of computational fluid dynamics, data mining and machine learning to identify new deposition conditions. |
