HGTR Fuel Brick
Coupled Thermal-Irradiation-Structural Analysis of HGTR Fuel Brick Using ABAQUS
Assygen and CUBIT were used in generating the models for this structural analysis. Axial and radial mesh size APREPRO variables in the template journal file created by Assygen were modified to create the desired mesh quality. The material considered is H-451 transversely isotropic graphite. At the end of 4.6 years radiation profile and inplane stress profile are shown. This assembly is located on the x-axis at a distance of 195.67cm from the center of core.
The details about the radiation and stress plots can be found on the ICAPP’12 paper:
