ナトリウム燃焼における多次元効果の検証のために、原子力機構においてSNL T3ナトリウム燃焼試験をAQUA-SFおよびSPHINCSコードを用いて検証を行った。解析において、試験中の燃焼停止期間を模擬し、ナトリウム液滴径の最適化を行うことで、試験結果の再現を行った。その際、AQUA-SFにおけるBest estimateの液滴径は2.5mmとなり、ハイスピードカメラによる測定と矛盾しない結果を得ることができた。

In order to investigate the multi-dimensional effects of sodium combustion, a benchmark analysis of the SNL Surtsey spray combustion experiment (SNL T3 experiments) using AQUA-SF and SPHINCS is conducted in JAEA. As a best estimate analysis, the spray burning duration is adjusted in the computation in order to take into account the temporary suppression of the spray combustion observed in the experiment. Furthermore, droplet size of SPHINCS and AQUA-SF are optimized to represent the T3 experimental results. The best estimate of AQUA-SF results in the droplet diameter of 2.5 mm, which agrees quite well with the spatial temperature measurements, and the sodium droplet diameter measurement with a high speed camera.
