摘要
具有石墨堆芯结构的反应堆类型包括生产堆、石墨水冷反应堆、气冷堆、高温气冷堆等。具有多体结构的石墨堆芯结构在地震激励下表现出与一般土木结构、金属焊接结构或螺栓连接结构所不同的特性。本文综述了在反应堆发展的四个阶段中,不同时期不同国家对石墨堆芯结构抗震的研究方法及成果。气冷堆发展的初期,石墨结构的整体特性研究很少,尚不能满足我们国家建造示范电站的需要。本文阐述了我国在设计、建造和运行HTR-10过程中关于石墨结构抗震的研究思路,并且介绍了HTR-PM项目研究进展以及今后将开展的侧反射层相似理论模拟研究。
Background： Reactors with graphite core structure include production reactor, water-cooled graphite reactor, gas-cooled reactor, high-temperature gas-cooled reactor and so on. Multi-body graphite core structure has nonlinear response under seismic excitation, which is different from the response of general civil structure, metal connection structure or bolted structure. Purpose： In order to provide references for the designing and construction of HTR-PM. This paper reviews the history of reactor seismic research evaluation from certain countries, and summarizes the research methods and research results. Methods： By comparing the methods adopted in different gas-cooled reactor cores, inspiration for our own HTR seismic research was achieved. Results ＆ Conclusions： In this paper, the research ideas of graphite core seismic during the process of designing, constructing and operating HTR-10 are expounded. Also the project progress of HTR-PM and the research on side reflection with the theory of similarity is introduced.
