Underground siting of nuclear power plant is one measures to meet the future siting which the electric utilities are currently studying. Underground caverns containing the reactor vessel are classified into tunnel type and cylindrical type by these confiquration. The carthquake resistance and the safety of caverns for each type were studied during earthquake observations and numerical analyses, and following results were obtained. (1) From the results of earthquake observations on the existing underground hydraulic power plants, it was found that the input earthquake forces were reduced, input seismic wave spectrum were simplified and earthquake responses of reactor building were controlled at the underground siting plant. (2) It was obtained that the stability of underground large caverns located at castal slope in Japans were maintained. (3) It was analysed that the earthquake responses of reacter building, equipment and piping systemes contained underground caverns were less than these of the surface ground siting plant. It was consequently found that the underground siting was advantageous in terms of earthquake resistance. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
