    Abstract: 核能發電為生活上帶來了許多便利,但其核能發電所產生之用過核燃料卻是汙染環境之一大問題,因此對於用過核燃料之處置將成為一個重要議題。而對於用過核燃料的最終處置方式,必須足以防止核廢料汙染物擴散至生物圈,國際間對此一課題進行許多評估與研究,深地層處置(deep geologic disposal)被認為是最安全可行的處理措施。本研究將以此概念進行分析。
    研究中採用日本文獻JNC(H12)所規範的核廢料地下掩埋處置模型進行分析,以有限元素分析法。在分析過程中,本研究主要針對處置場中之包件材料之腐蝕膨脹進行分析,在研究中分為三部分,第一部分為不考慮外包件腐蝕膨脹之效應之處置場的熱-水-力學分析驗證;第二部分為外包件之腐蝕膨脹分析驗證,其分析材料僅包含外包件與緩衝材料;第三部分為整個處置場熱-水-力學分析及外包件腐蝕膨脹對其之影響,以上分析可提供未來分析處置場時,需考慮之各時期真實情形。


    關鍵字:深層地層處置、外包件腐蝕膨脹、有限元素法
    ;The nuclear power has brought a lot of convenience for the life, But its arising from used nuclear fuel is one of the big problems of environmental pollution, So for the disposal of used nuclear fuel it will be an important issue. For the final disposal of used nuclear fuel, must be sufficient to prevent the spread of pollutants to the biosphere.
    There are many country studying and evaluation about this issue, they consider that the deep geological disposal is the most safe and feasible measure. The study will analyze on this concept.
    This study will use the deep geological disposal model of Japan reference (JNC H12) and finite element method to analyze. During the analysis, the study is directed against the disposal of the overpack corrosion expansion analyzed.
    The study is divided into three parts. First, the verification of coupled thermo-hydro-mechanical without overpack corrosion expansion effect. Second, the verification of overpack corrosion expansion , and the materials included buffer and overpack. Third, the analysis of coupled thermo-hydro-mechanical and overpack corrosion expansion effect. The above analysis may provide future disposal sites when analyze of the situation needed to consideration.
