摘要: There is provided a holding device which can hold a molten corium for a predetermined period even when the molten corium is exposed to heat or undergoes any chemical reaction and which is applicable to practical use. There is provided a holding device provided below a nuclear reactor pressure vessel for holding a molten corium, wherein the holding device includes a base material in contact with a cooling medium, and a multilayer stack structure on the base material. The multilayer stack structure has a first layer having heat-resistant property, a second layer formed on the first layer and having heat-resistant property with lower heat conductivity than that of the first layer, and a third layer formed on the second layer and having corrosion-resistant property and impact-absorbing property.
摘要翻译: 提供了一种保持装置,即使在熔融的金属暴露于热或经历任何化学反应并且适用于实际应用的情况下,其也可以将熔融的金属晶体保持预定的时间。 提供了一种保持装置,其设置在用于保持熔融的金属的核反应堆压力容器下方,其中保持装置包括与冷却介质接触的基材,以及在基材上的多层堆叠结构。 多层堆叠结构具有耐热性的第一层,形成在第一层上的具有比第一层低的导热性的耐热性的第二层,以及形成在第二层上的第三层,具有 耐腐蚀性和冲击吸收性。
