JUPITERコードの炉心溶融現象解析における溶質拡散モデルに対して、既往研究結果に対する検証解析を実施した。その結果、既往研究結果と良好な一致を示し、JUPITERコードの溶質拡散モデルの妥当性を確認することができた。

Various numerical simulations were performed by JUPITER code in order to validate the reliability of its multi-physics models, which were developed for evaluating the melting and relocation behavior of the core materials. By comparing with the previous experimental results, we could conclude that JUPITER code is a useful tool on severe accident analysis.
