深層地質處置(deep geologic disposal)為國際間經過評估與研究認為最安全可行的用過核燃料最終處置措施。 本文以有限元素軟體ABAQUS進行以深層地質處置概念為基礎的處置場母岩熱傳導分析與處置罐圍壓分析。 使用參考瑞典SKB等相關文獻所提供的模型幾何、材料參數、初始條件及邊界條件建立具同等效力模型，利用代表體積單元概念建立設計參考圖進行數值分析，求得處置孔內峰值溫度並與文獻平行驗證，進而針對母岩熱傳導參數進行分析與文獻驗證。 並利用多處置孔模型進行母岩熱傳導係數「空間異質性」之熱傳導分析，研究均質與非均質母岩熱傳導係數之影響效應。 除上述熱傳導分析，本文參考台電與瑞典相關文獻建立處置罐模型，模擬處置罐在承受回脹壓力與冰川壓力負載環境下的圍壓分析，並進行模型及材料參數分析。 ;Deep geologic disposal is the most safe of nuclear fuel final repository that have been evaluated and studied internationally. Use the finite element software ABAQUS to simulate heat transfer analysis of the repository and the confining pressure analysis of the disposal canister.
Using the model geometry, material properties, initial conditions and boundary conditions provided by the Swedish SKB to establish an equivalent model. Using the representative volume unit concept to establish a Nomographic spacing-temperature chart for numerical analysis, to obtain the peak temperature in the deposition hole, and then analysis and review literature of the thermal conductivity parameters of the rock.
The multi-disposal hole model is used to analyze the thermal conductivity of the rock thermal conductivity coefficient "spatial variabiltiy" to study the effect of heat transfer coefficient of homogeneous and heterogeneous rock.
In addition to the above heat conduction analysis, this study refers to the Taiwan Power Company and Swedish related literature to establish a disposal canister model, simulate canister in the analysis of the swelling pressure, and carry out model and material property analysis.
