This paper presents a method to estimate the probability of an unfiltered release to the environment due to failure of the heating, ventilation, and air-conditioning (HVAC) system in the Waste Handling Building (WHB) at the proposed waste repository at Yucca Mountain. The scope of the calculation is limited to the function of the WHB HVAC system to maintain its once-through capability, that is, the ability to draw air through the various confinement areas through the high-efficiency particulate air (HEPA) filters, before exhausting the air to the atmosphere through the exhaust air stack. The ability to draw air through the WHB also maintains negative pressure between confinement areas (causing air flow inward rather than toward the environment). Other functions of the HVAC system, e.g., room heating and cooling for comfort, were not considered in this analysis.
