Development of a High Temperature Gas-Cooled Reactor TRISO-coated particle fuel chemistry model
… of the SiC layer are additionally modeled. The amoeba effect is added as a new failure mode. The palladium penetration model has the most significant result on the overall fuel performance model and increases the number of predicted particle failures. The thinning of the SiC layer due to fission …

The Effect of Coating Parameters On Advanced TRISO Fuels With Zirconium Carbide
… presence of a temperature gradient, known as the amoeba effect. To negate these problems a solution of adding a ZrC gettering layer between the kernel and PyC buffer layer has been proposed. The purpose of this study is to provide insight into the coating parameters and how they affect the coating …

The Deposition Characteristics of Zrc On Uo2 Kernels Produced For Advanced Triso Fuels In Gen-Iv Reactors
… help minimize typical TRISO fuel failures of the amoeba effect, cracking and over pressurization. The ZrC layer was initially deposited on surrogate zirconia kernels using a chemical vapor deposition (CVD) coater and the effects of varying gas flow rates were studied for optimization. The layers …

Analysis of U-Zr-C-O Quaternary System for Applications in Advanced ZRC Coated Triso Particles
<p>The implementation of ZrC for use in oxide TRISO particles for Very High Temperature Reactor (VHTR) conditions to prevent kernel overpressurization and kernel migration has been proposed by several researchers. Analysis is performed incorporating first-principles thermodynamics along with …
