［摘要］采用安全殼內置換料水箱（IRWST）是中核集團“華龍一號”主要技術改進項之一。安全殼內置換料水箱布置在內部結構廠房基礎底板之上，引起了反應堆廠房內部結構整體穩(wěn)定、抗滑移、溫度作用、結構整體分析、流固耦合、施工階段驗算等方面的變化，針對上述問題進行研究，同時對所采取的計算分析方法進行探討，并將該成果應用到了“華龍一號”的工程實踐中，目前福清5/6號機組內置換料水箱土建施工已經完成，研究成果得到了很好的驗證，具有一定工程價值。

Abstract:The use of in-containment refueling water storage tank (IRWST) is one of the key technical improvements of “Hualong One” by China National Nuclear Corporation. It is arranged on the foundation slab of the internal structures, which changes the overall stability, anti-sliding, temperature effect, structure analysis, fluid-structure interaction and construction phase checking of the reactor buildings. The problems mentioned above were analyzed and the calculating methods were discussed, and the results was applied in the “Hualong One” project. The construction of IRWST in the Fuqing 5/6 unit has been finished. The research results have been well verified and have engineering values.
Keywords:Hualong One; in-containment refueling water storage tank(IRWST); fluid-structure interaction(FSI); temperature effect; HPR1000
