High temperature gas-cooled reactors (HTGR) have enhanced passive safety characteristics. Even if in the case of "station black out" where all electric power supplies are not available, HTGR can cool its decay heat from the core. In this paper, the core design and safety assessment are performed for commercial-size 600MWth prismatic type HTGR. Power density distributions in the core that are obtained with nuclear analyses are applied to temperature analyses in normal operation, and in the depressurization accident condition where no active cooling devices are assumed to work. In the results, the fuel temperature in the normal operation and the accident condition are satisfied its criteria respectively, that proves its superior safety feature without any active devices.
