| 中文摘要 | 用過核子燃料深層地下處置一般可分為「垂直向」及「水平向」兩種廢料罐放置方式,後者又稱 為「水平向備案」,其概念相對較未普及,但具有多項優點,因此確認其適用性是當前重要的階段性議題;此 外,在處置過程中,極可能在近場之母岩中形成裂縫,加速障壁系統之劣化。本研究因此針對水平向處置概 念,考慮裂縫之影響效應,進行熱-水力-力學耦合分析;分析結果期可提供相關設計參考,有效提升處置環境 之安全與穩定。 |
| 英文摘要 | Two design schemes have been proposed for deep geologic repositories of spent nuclear fuel, including the "vertical canister disposal method" and the "horizontal canister disposal method". The latter is also termed the horizontal alternative and is not as popular as the vertical one. Nevertheless, due to its several advantages, confirming whether the horizontal disposal method satisfies the same long-term safety requirements as an appropriate alternative is a very important issue at present. As an aside, during the disposal process, rock fractures may be introduced and will possibly accelerate the deterioration of the barrier system. The aim of this research is presented to analysis of the nearfield T-H-M coupling behavior in a deep geological repository with the horizontal disposal method. The finite element transient analyses will be carried out to predict the effects of the influencing factors resulting from the presence of rock fractures. Results of the presented analyses are anticipated to be applicable for future reference in practical engineering design. |
