• Being situated in a frequent seismic area, aseismic analysis of nuclear reactor to be constructed in this country are strictly required in its safety consideration. For the JPDR, Japan's first nuclear power station, we have analyzed, in its design stage, vibration characteristics of Reactor Enclosure Structure, for the factors such as natural period, damping accleration etc., to check the validity of static design earthquake coefficient. After completion of the plant, many seismic sensors have been mounted on various parts of the Enclosure Structure to observe its vibration characteristics during earthquake. Using the data obtained so far from actual earthquake, the natural period, location of rocking centers, etc. were calculated. The calculated values show good agreement with the above mentioned analytical results.
