原子力施設の重大事故におけるソースターム評価の高度化に資するため、文献調査及び第一原理計算により気相中のRu-N-O-H系化学反応速度定数のデータベースを構築した。試解析により、データベースにおいて化学反応の抜けが無く、Ruの化学形態の経時変化を解析できることが確認されたことから、構築したデータベースが化学反応速度を考慮したRu化学形態評価に適用可能であることが分かった。

In order to contribute to the improvement of source term under severe accidents of nuclear facilities, a database of gaseous phase chemical reaction rate constants in the Ru-N-O-H system was developed. The data implemented in the database were prepared by either literature review or, if the literature data was not available, ab-initio based calculation. It was confirmed by preliminary analyses that there is no lack of reaction path in the database and the changes of Ru chemical forms were successfully calculated. These results indicated that the developed database would be useful to evaluate Ru chemical forms considering the chemical reaction kinetics.
