Summary:To suppress the amount of generation of hydrogen due to reaction with a molten material, in a reactor facility.SOLUTION: A reactor facility 1 includes: a reactor vessel 2c which is formed of a material containing zirconium, and which stores a fuel assembly 4a; a reactor pit 15 including a bottom face 15b which is provided in a manner to face a lower part of the reactor vessel 2c; a heat resistant layer 21 which is laid on the bottom face 15b, and which is formed of a material containing a metal oxide; and a sacrificing layer 22 which is laid on the heat resistant layer 21, and which is formed of an iron oxide-containing material having a melting point lower than that of a material forming the fuel assembly 4a.SELECTED DRAWING: Figure 1 【課題】溶融物との反応による水素の発生量を抑える。【解決手段】原子炉設備１は、ジルコニウムを含む材料で形成された燃料集合体４ａを収容する原子炉容器２ｃと、原子炉容器２ｃの下方に対向して設けられた底面１５ｂを有する原子炉ピット１５と、底面１５ｂ上に積層されて、金属酸化物を含む材料から形成された耐熱層２１と、耐熱層２１上に積層されて、燃料集合体４ａを形成する材料よりも融点が低く、かつ、酸化鉄を含む材料から形成された犠牲層２２と、を含む。【選択図】図１
