ナトリウム冷却高速炉蒸気発生器のナトリウム-水反応現象に関して、反応領域中において、ボイド率$$alpha$$-熱伝達率h相関図を用いて熱伝達率を推定して管壁温度を解析する高温ラプチャ評価手法を構築した。本手法を多次元Na-水反応場数値解析の結果に適用して、高温ラプチャの可能性や発生時刻の評価を行った結果について報告する。

The authors have constructed a new evaluation method of overheating tube rupture of steam generator in sodium-cooled fast reactor in which heat transfer coefficients are estimated by using an correlation between void fraction and heat transfer coefficient, and tube wall temperature was calculated by estimated heat transfer coefficient. The authors report the evaluation result of the probability and occurrence time on overheating tube rupture by application of the multi-dimensional analysis result of the sodium-water reaction field.
