A platform has been developed for automated general geometry, external coupling of MCNP6.1 and OpenFOAM/STAR-CCM+ for the purposes of corrosion modeling in reactor conditions. General geometry coupling is achieved by mapping CFD regions used in conjugate heat transfer simulations to MCNP cells rather than mapping mesh elements to cells. The utility maps the temperature field from the CFD code to the MCNP cells and updates the cell densities, surface parameters, and cross-sections to account for temperature dependence. The utility then updates the power distribution in the CFD case and obtains a corrected temperature distribution. The process is repeated until convergence of the temperature and power distributions. The Makxsf utility is used to obtain temperature-adjusted Doppler broadened cross-sections for all nuclides in the system. The flow accelerated corrosion models being developed for the Lobo lead loop can be readily integrated to model corrosion in reactor temperature distribution and fluid flow conditions.
