| Abstract Scope |
Coated particle fuels are made of a uranium-bearing kernel coated with different layers of ceramics or metals. The most known and studied coated particle fuel is the Tristructural-isotropic (TRISO) coated particle nuclear fuel, which is composed of a uranium oxide or oxycarbide (UO2/UC/UC2) kernel coated with three layers of pyrolytic carbon (PyC) and one layer of SiC. New coated particle fuels have been proposed for future microreactor designs for terrestrial use and space exploration. This expanded service envelope in many cases will require the fabrication of coated particles with new combinations of kernels (composition, shape, and size) and coatings (number, composition, and thicknesses). In this work, we discuss the challenges and limitations associated with developing new coated particle fuels and the use of new tools such as machine learning, computational fluid dynamics, particle image velocimetry, and data mining to accelerate their development. |
