Description

The Mizunami Underground Research Laboratory (MIU) Project is being pursued by the Japan Atomic Energy Agency (JAEA) to enhance the reliability of geological disposal technologies through investigations of the deep geological environment in the crystalline rock (granite) at Mizunami City, Gifu Prefecture, central Japan. On the occasion of JAEA reformation in FY2014, JAEA identified three remaining important issues on the geoscientific research program based on the synthesized latest results of research and development (R&D): 'Development of countermeasure technologies for reducing groundwater inflow', 'Development of modeling technologies for mass transport' and 'Development of drift backfilling technologies'. At the MIU, the R&D are being pursued with a focus on the remaining important issues from FY2015, and satisfactory results have been achieved. Based on this situation, the R&D on the MIU Project were completed at the end of FY2019. In this report, the results of R&D and construction activities of the MIU Project in FY2019 are summarized.

Abstract (Japanese)

日本原子力研究開発機構東濃地科学センターでは、高レベル放射性廃棄物の地層処分技術に関する研究開発のうち、深地層の科学的研究(地層科学研究)の一環として、結晶質岩(花崗岩)を対象とした超深地層研究所計画を進めている。本研究所計画では、2014年度に原子力機構改革の一環として抽出された三つの必須の課題(地下坑道における工学的対策技術の開発、物質移動モデル化技術の開発、坑道埋め戻し技術の開発)の調査研究を進めてきた。これらの必須の課題の調査研究については十分な成果を上げることができたことから、2019年度をもって超深地層研究所計画における調査研究を終了することとした。本報告書は、2019年度に実施した超深地層研究所計画のそれぞれの研究分野における調査研究,共同研究,施設建設等の主な結果を示したものである。(著者)
