A multidimensional, mountain-scale, thermal-hydrologic (TH) numerical model is presented for investigating unsaturated flow behavior in response to decay heat from the proposed radioactive waste repository in the Yucca Mountain unsaturated zone (UZ), The model, consisting of both two-dimensional (2-D) and three-dimensional (3-D) representations of the UZ repository system, is based on the current repository design, drift layout, thermal loading scenario, and estimated current and future climate conditions. This mountain-scale TH model evaluates the coupled TH processes related to mountain-scale UZ flow. It also simulates the impact of radioactive waste heat release on the natural hydrogeological system, including heat-driven processes occurring near and far away from the emplacement tunnels or drifts. The model simulates predict thermally perturbed liquid saturation, gas- and liquid-phase fluxes, and water and rock temperature elevations, as well as the changes in water flux driven by evaporation/condensation processes and drainage between drifts. These simulations provide insights into mountain-scale thermally perturbed flow fields under thermal loading conditions.
提出了一个多维、山脉尺度的热-水文（TH）数值模型，用于研究内华达山脉非饱和带（UZ）中拟建放射性废物处置库衰变热引起的非饱和流行为。该模型由UZ处置库系统的二维（2-D）和三维（3-D）表示组成，基于当前的处置库设计、巷道布局、热负荷情景以及估计的当前和未来气候条件。这个山脉尺度的TH模型评估了与山脉尺度UZ流相关的耦合TH过程。它还模拟了放射性废热释放对天然水文地质系统的影响，包括在距安置巷道或硐室远近不同位置发生的热驱动过程。该模型模拟预测热扰动下的液体饱和度、气相和液相通量、水和岩石温度升高，以及由蒸发/冷凝过程和巷道间排水驱动的水流通量变化。这些模拟为热负荷条件下山脉尺度的热扰动流场提供了见解。
