The paper describes the results of a ventilation study involving subsurface heat and moisture flow at Yucca Mountain (YM), Nevada. MULTIFLUX (MF), a fully-coupled, hydrothermal-ventilation model and software code is used to model the flow of heat, moisture, and air in a subsurface airway within the conceptual, high-level nuclear waste repository proposed to be built at YM. The hydrothermal-ventilation/heat flow model and software MF is a universal coupler that connects the heat and moisture transport calculations in two different domains: (1) the rockmass, with a NUFT-based NTCF model, and (2) the airway with the heat-generating nuclear waste packages, using a CFD model. Temperature, relative humidity and water condensate variations are analyzed in the emplacement drift, assuming air movement, to determine the conditions of the psychometric corrosion environment in the emplacement area. The calculation results show condensate formation in the cold drift section, and are found to be sensitive to choosing from two different CFD model configurations.
