PASCAR(Proliferation-resistant, Accident-tolerant, Self-supported, Capsular and Assured Reactor) has been developed with 35MWe(100MWth) operating without primary coolant pump, capitalizing on natural circulation capability of lead-bismuth eutectic(LBE) for long-life small and robust power units. To ensure the structural integrity, the large safety margin against Safe Shutdown Earthquake, 0.3g, and furthermore the cost effectiveness for PASCAR, 3-D seismic base isolation design has been developed. The analytical model has been developed and seismic time history analyses has been carried out. The advantage for using 3-D seismic base isolation for PASCAR has been discussed.
