abstract = "The neutron transport code DeCART and the commercial CFD code STAR-CD are being integrated into the SHARP reactor analysis toolkit to extend its applicability to high-fidelity analysis of prismatic VHTR cores. The CFD analysis provides detailed intra-compact temperature feedback to DeCART based on the intra-compact power distribution predicted by DeCART. A demonstration calculation of the coupled DeCART/STAR-CD capability was performed for a 1/6 VHTR core model. The coupled calculation exhibited good convergence characteristics, and performed five iterations between DeCART and STAR-CD in 18 hours on twelve 8-core nodes of a high-performance Linux cluster. While the results of the analysis are preliminary and model improvements and validation exercises are ongoing, this calculation demonstrates that performing such analyses on current-generation computing platforms are now feasible. Ongoing work in this effort includes the implementation of the geometry and mesh database tools CGM and MOAB for efficient, inter-operable coupling as well as the inclusion of new meshing tools to facilitate the model development process.",
