Note (General): Within the scope of the JAEA thermodynamic database project for performance assessment of geological disposal of high-level radioactive and TRU wastes, refinement of the thermodynamic data for the inorganic compounds and complexes of actinium, plutonium(III), americium, curium and samarium was carried out. Refinement of thermodynamic data of these elements was performed on a basis of the thermodynamic database for americium published by the Nuclear Energy Agency in the Organisation for Economic Co-operation and Development (OECD/NEA). Based on the similarity of chemical properties among trivalent actinides and samarium, complementary thermodynamic data for their species expected under the geological disposal condition were selected to complete the thermodynamic data set for the performance assessment of geological disposal of radioactive wastes.
高レベル放射性廃棄物及びTRU廃棄物の地層処分の性能評価に用いるための熱力学データベースの整備の一環として、アクチニウム,プルトニウム(III),アメリシウム,キュリウム及びサマリウムの熱力学データの再選定を実施した。熱力学データ選定は、経済協力開発機構原子力機関が公開しているアメリシウム熱力学データベースの内容をもとに行った。地層処分における地下水条件のもとで存在の可能性がある化学種でありながら、これらの調査でそのデータが欠落しているものについては、サマリウム及び3価アクチノイドの化学挙動が類似していると考えられることを利用して、推定した熱力学データを追加することでデータベースの補完を行った。
