Interaction between metal fission products and TRISO coating materials: A study of chemical bonding and interdiffusion

The goal of this project is to elucidate the chemical bonding and interface formation of metal fission products with the coating materials used in state-of-the-art TRISO fuel particles. Particular emphasis is placed on an analysis of intermediate chemical phases at the interface, the intermixing/diffusion behavior, and the electronic interface structure as a function of material choice (metal a...

X-ray fluorescence microtomography on a SiC nuclear fuel shell

TRISO fuel particles, used in high-temperature gas-cooled reactors (HTGR) are composite structures with a nuclear fuel kernel surrounded by alternating layers designed to contain fission products and compensate for radiation damage. As shown in Figure 1, a typical fuel particle contains an inner kernel of nuclear fuel, a low-density buffer layer of pyrocarbon, a dense layer of pyrocarbon coatin...
