日本原子力研究開発機構では、水素の発生から拡散、燃焼、爆発に至る挙動を予測する水素挙動解析システムの構築を進めている。本報では、システムの概要と水素挙動解析システムの構築に向けた取り組みの一環として、OECD/NEAのISP47等のTOSQAN試験データを用いたコード検証事例を報告する。

To further improve the safety performance of the Nuclear Power Station, especially on the hydrogen safety under severe accident conditions, a simulation code system has been developed to analyze hydrogen behaviors including diffusion, combustion, explosion and structural integrity evaluation. Preliminary calculated results obtained with above mentioned tools agreed well with ISP47 TOSQAN test data of OECD/NEA project.
