本報告書は、2007 年に OECD/NEA 放射性廃棄物管理委員会が始めた可逆性と回収可能性(R&R)に関する 4 年間にわたる国際プロジェクトの最終的な詳細報告書である。本プロジェクトの主要なマイルストーンは、文献調査を行うこと、NEA 加盟諸国の R&R に対する考え方を調査すること、および広範な関係者グループ内で議論することであった。この議論は、フランスのランスでの国際会議・意見交換会(...

放射性廃棄物は、医療・産業・研究・発電など幅広い活動から発生する。このような廃棄物はすべて、人の健康と環境の保護を最優先して安全に管理しなくてはならない。何十年にも及ぶ研究活動を経て、国際科学界は今では、高レベル放射性廃棄物を深地層最終処分場(DGR)に定置することが安全かつ効果的であると確信するに至っている。
各国政府は、それぞれが最良であると信じるエネルギー・環境政策を実施する絶対的な権利と責...

放射性廃棄物の地下処分プログラムでは、処分場設計に用いる地層科学パラメータの不確実性や長期安全性が問題となる。誰もが受け入れられる安全な放射性廃棄物処分プログラムを構築するためには、実施主体、規制側、研究者、政治家、一般市民の間で活発な議論を行い、URL などの地下施設を建設して、岩盤の特性調査、試験、技術開発、実証活動を計画・実施していく必要がある。
このような中、本資料では 2001 年に発行...
