Abstract

Abstract

Prismatic dispersed microencapsulated fuel is a particle-reinforced composite fuel which is formed by TRISO fuel particles dispersed in metal or ceramic matrix. It has good structural stability, fission product inclusion capacity and irradiation stability, and it is one of the promising fuels in high temperature gas-cooled reactor. A prismatic dispersed microencapsulated fuel with TRISO particles dispersed in SiC matric was proposed in this paper. Based on the finite element analysis software COMSOL, the 3D thermal-fluid-solid coupling analysis model of the fuel element is established, and the performance analysis and optimization design of the fuel element are preliminarily realized. The results show that the maximum temperature of the prismatic dispersed microencapsulated fuel element is located on the outside of the fuel element, the peak stress is on the wall of the coolant channel, and the thermal stress of the fuel element is the lowest when the edge-distance ratio is 0.76 to 0.84 and the hole-distance ratio is 0.68 to 0.75. The performance analysis method and research conclusions of the prismatic dispersed microencapsulated fuel established in this paper can provide guidance and reference for the subsequent design of this type of gas-cooled reactor fuel element.
