Abstract:	我國用過核子燃料最終處置計畫自107年起邁入「候選場址評選與核定」之第二階段，因此，處置計畫的審查、驗證及管制等長期工作，將參酌國際間高放最終處置安全論證報告技術評估要項，以及核能先進國家相關法規、導則、安全要求或高放最終處置設施安全分析報告之審查案例，以推動我國用過核子燃料最終處置設施安全分析報告導則之研擬工作，期能完備我國高放最終處置相關法規。　　本計畫擬針對用過核子燃料最終處置安全分析報告相關內容需求，彙整國際組織提出之高放射性廢棄物最終處置有關安全規範或導則，以及主要核能國家對於高放廢棄物地質處置設施設計之安全標準與技術要項、高放廢棄物地質處置安全分析報告審查案例等，研提我國用過核子燃料最終處置設施安全分析報告導則之設施設計專章，並提出未來審查要項建議。　　同時，針對用過核子燃料處置安全評估所需的重要管制資訊及技術，進行實驗與模擬成果之平行驗證，包括處置設施國際合作地下現地實驗結果與地震分析數值模擬之平行驗證、處置孔內低密度緩衝材料之行為模式及其對應之熱-水-應力耦合效應影響等重點工作，以掌握處置設施設計審查重點並提升國內相關管制技術與審查能力。 ;Starting from 2018, the geological disposal program for spent nuclear fuel has moved to the second phase of identifying potential areas for a repository site. Thus, the development of the requirements and/or guide for the safety analysis report of the geological disposal facility becomes essential. This will be set out by referencing to the main issues discussed in international geological disposal programs and reviewing comments provided to various states on their disposal project’s safety analysis report by regulating agencies. This is expected to benefit the forthcoming review of the safety assessment reports to be submitted and the control of the final disposal program administered by Taipower. 　　This project is to assimilate the safety requirements and/or guides established by international organizations for geological disposal facility of high-level radioactive wastes and the design criteria of geological disposal facility adopted by various countries. Based careful examination of the information, a draft guide for the safety analysis report on geological disposal facility will be devised. Documentation of the guide will begin with a chapter on facility design, along with suggestions on major technical review issues. 　　In addition to the preparation of design guide for geological disposal facility, a couple of verification tasks on important safety features of the disposal facility are included in the project. These tasks are intended to be conducted independently such that major findings from Taipower’s safety assessment reports and/or international collaborated researches can be compared/verified. Thus, two technical sub-studies, namely, verifications on the results from field experiments conducted through international collaboration and seismic analysis/simulation, and the behavior of low density buffer and its effects on the thermos-hydro-mechanical coupling function in the deposition hole, are included in this research project.
