高速炉冷却材であるナトリウムの漏えい燃焼を想定した場合の基本現象理解と多次元数値解析評価手法の妥当性確認に資するため、隣接する矩形の2部屋が開口部でつながる体系におけるナトリウム燃焼試験の結果を分析・評価した。ナトリウムが空気中でプール状に燃焼する際の複数点温度測定データから、体系の幾何形状条件や熱流動の多次元性に起因する雰囲気温度分布の特徴を明らかにすることができた。

A liquid metal sodium leak and pool fire experiment has provided the transient temperature data measured in more than 100 positions for atmospheric gas and structures. The experiment was performed in an air-filled 2-cell geometry that was made by partitioning the room of rectangular cell with an opening between the cells. The analyses of the measured data clarified the basic characteristics of sodium pool combustion and consequential heat and mass transfer in the cells. The data also suggested several features of multi-dimensional thermal-hydraulic behaviors that occurred in the experimental geometry during the fire. The measured data are expected to be utilized for the validation study of numerical sodium fire analysis tools.
