| 摘 要： | 安全壳是核电厂反应堆主厂房的围护结构,是防止设计事故发生时放射性物质扩散的最后一道屏障,是确保核电厂安全的关键设施.因此,必须在设计中考虑到安全壳在可能的、会引发重大核事故的意外荷载作用下的工作性能.地震是核电厂整个使用过程中有可能出现的自然灾害之一,并可能引发重大事故,所以,必须对安全壳结构进行严格的抗震性能分析,设计要保证预应力混凝土安全壳能够承受SSE作用而不被损坏.本文通过有限元模型的计算与分析,得到先进核电厂半球顶安全壳结构在SSE作用下的应力、变形、位移等地震反应,由此进行安全壳结构构件抗震分析计算.计算表明,半球顶安全壳结构在SSE作用下,安全壳结构安全可靠,结构的设计能够满足我国核电厂安全导则对抗震Ⅰ类结构的规定.

| Abstract: | Containment is the enclosure structure of reactor building for nuclear power plant(NPP),which prevents the leakage of radioactivity material out of NPP,when accidents occur.It is the key component for safety of the nuclear power plant.So it must be designed to resist the load under severe accident.Earthquake is one of potential natural disaster during the plant service life.And earthquake may result in severe accident.Seismic analysis should be performed for the containment.Prestressed concrete containment ... |
