Abstract

The safety potentiality of a light water reactor (LWR), a fast breeder reactor (FBR) and a high temperature gas cooled reactor (HTGR) was compared from the aspect of the reactor-shutdown, decay heat removal and containment of radioactive material at the accident. The HTGR has the higher safety potential because it doesn't require the instant reactor shutdown, active decay heat removal with coolant and containment vessel.

The HTGR has the possibility to apply the different safety criteria. The cost reduction effect has been studied due to changes of safety grade.
