获得不锈钢熔体和碳化硼混合合金(SUS316L+B4C合金)的粘度对于改进钠冷快堆严重事故评估方法具有重要意义。为使粘度测量装置的性能作为第一步，用摆动坩埚法测量了镍(Ni)熔体和不锈钢(SUS316L)熔体的粘度。测量了熔融Ni和SUS316L熔体在1823K以下的粘度，发现熔融Ni和SUS316L熔体的测量粘度与实验数据的偏差分别为±4%和±3%。研究还发现，熔融Ni和SUS316L与熔融Ni和类似复合不锈钢的文献值相近。此外，我们还初步测定了SUS316L-5质量分数B4C合金的熔体粘度。熔融镍和SUS316L的粘度的fi测试结果如下。
It is important to obtain the viscosity of a mixed alloy consisting of molten stainless steel and boron - carbide （ SUS316L ＋ B 4 C alloy ） for the improvement of severe accident assessment methodology for sodium - cooled fast reactors. In this study, the viscosities of the molten nickel （ Ni ） and stainless steel （ SUS316L ） were measured by the oscillating crucible method to confirm the perfor - mance of the viscosity measurement apparatus as a first step. The viscosities of molten Ni and SUS316L melts were measured up to 1823 K. It was found that the measured viscosity values of molten Ni and SUS316L were estimated from the deviation of the exper - imental data, were ± 4 ％ and ± 3 ％ , respectively. It was also found that those of molten Ni and SUS316L were close to those of the literature values of molten Ni and similar composite stainless steels. Moreover, we tentatively measured the viscosity of molten SUS316L - 5 mass ％ B 4 C alloy. The fitted results of the viscosity for molten Ni and SUS316L were represented as follows.
