A core seismic analysis method for FR has been developed to evaluate 3D core vibration behavior considering fluid structure interaction and vertical displacements (rising).
In this presentation, the analysis model to consider the influence of core element deformation due to heat and irradiation was verified by comparing the seismic test which used deformed core assembly mock-ups and analysis results.
