高階核廢料其高放射線與殘存衰變熱等有害物質，必須對生物圈與環境是無害的，國際間均認為最安全可行的處理措施為深地層處置。 本研究以有限元素軟體ABAQUS進行完全耦合熱-水-力學之分析。處置場分析研究以深地層處置之概念為基礎，參考日本H12相關文獻，考慮熱源、緩衝材料、回填材料、母岩之熱與水力特性進行分析並對照文獻之結果。 多處置孔分析，以「代表體積單元」分析，其幾何配置與材料參數係參考核能研究所(2002)之概念設計。但真實的處置場幾何配置與材料性質並不會完全相同，在此情況下，「代表體積單元」則不適合作為分析使用，因此採用的模型概念為「處置設施多孔幾何配置」，較能呈現出真實情況。 ;Spent nuclear fuel waste must be harmless to the environment and zbiological. After the international evaluation and research, deep geological disposal is considered the most safe and effective treatment measures. In this study, based upon the concept of the deep disposal method, thinking about the thermal, hydrological and mechanical properties of the paper in Japan(JNC H12). Considering the spent nuclear fuel waste, buffer materials, backfill material and rock material thermal and hydraulic characteristics of for analysis and comparison of the results of the literature countries. The distance of deposition holes and disposal field size analysis using the Taiwan Power Company′s exploration data, and considering domestic literature of the size of disposal site and material properties, In the disposal site, We use concept of “Representative volume element” to analysis, and If the shape or material properties is different ,we need use the Multi disposal hole analysis, to Presented the real situation.
