Heat Transfer Analysis of Microscale UO2 Particle-Graphite System in TREAT Fuel

  • 1. Argonne National Laboratory, 9700 South Cass Ave, Argonne, IL 60439 (United States)

Description

The Transient Reactor Test Facility (TREAT) at Idaho National Laboratory in the United States is now being prepared to restart its operation and perform transient testing to assist with advanced fuel development. In parallel with TREAT restart preparations, a program is underway to develop a low-enriched uranium core to replace the current highly-enriched uranium core. In this study, heat transfer simulation of UO2 particle- graphite systems in highly-enriched and low-enriched fuels for TREAT was performed using the finite element method (FEM). The irradiation degradation of both UO2 particles and graphite was taken into account in the simulation. The UO2 particle size limits for both HEU and LEU fuels were discussed based on the FEM simulation. In addition, a prototypical particle-distribution model was developed to evaluate the effect of size and spatial distribution of UO2 particles within the graphite. (author)
