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.
