dc.description.abstract	深地層處置(deep geologic disposal)為國際間認為最為安全且可行之用過核子燃料最終處置方式。 本研究將以深地層處置概念為基礎以有限元素軟體ABAQUS模擬處置場內部之熱傳導分析，參考瑞典SKB報告等相關文獻以處置場母岩、緩衝材料、回填材料、間隙等參數進行分析並對照文獻之分析結果。 除上述參數分析外，本研究也將進行處置場內廢料罐之間距尺寸參數分析，本研究將使用等效模型概念建立簡化網格後仍具同等效力之模型，並探討處置孔內最高溫與廢料罐間距之關聯性。 此外本研究將延續等效模型概念建立多處置孔分析模型，其中包括單處置隧道及雙處置隧道兩種形式，探討非單一處置母岩熱傳導係數與處置孔內最高溫之關聯性。	zh_TW
dc.description.abstract	Radioactive wastes are required to be isolated from the environment to prevent possible contamination. The deep geological repository with multiple barriers is currently recognized as a feasible disposal concept. In an underground disposal site, the radioactive wastes are encapsulated in containers surrounded by a buffer material which is and the excavation backfilled with a mixture of clay and sand. To develop three dimentional geometric model for the analysis of the near field of a deep underground repository using the multi-borehole approach, and the concept equivalent model to reduce the number of grids. The present report describes a model with nine canisters and a tunnel assuming symmetric conditions. These calculations were carried out using a PC-program for three-dimensional heat transfer, and make sure the bentonite buffer temperature does not exceed 100°C for any canister deposited.	en_US
