What is Thermal conductivity of UO2 pellets enhanced by a semi-continuous structure of Ti3SiC2 about?

The current distribution structure of the thermal conductivity (TC) enhancements in UO 2 matrix can be divided into three categories: dispersed structure, continuous structure and oriented structure. This paper develops a new semi-continuous structure to improve the TC of UO 2 . Ti 3 SiC 2 is selected as the enhancement in this paper due to its excellent irradiation resistance and high TC at elevated temperature. The semi-continuous structure of Ti 3 SiC 2 is formed through a simple centrifugal spheroidization of UO 2 and a followed powder mixing process. Both the theoretical prediction and experimental results indicate the semi-continuous structure has a close TC enhancing efficiency to the continuous structure. Meanwhile, the semi-continuous structure has the advantages of simplifying the fabrication process and can be applied to more kinds of enhancements compared to the continuous structure. The TC of Ti 3 SiC 2 /UO 2 is remarkably improved at elevated temperature compared with pure UO 2 , which is beneficial to the fuel safety.
