Abstract
Both inherent safety features and passive safety systems can help to achieve the safety requirements of INPRO and GenIV and may improve the public acceptance of nuclear power. Passive systems for heavy and light water reactors can help to reduce the core damage frequency, and thus, also the investment risk. Moreover, they can help to reduce the capital cost of new reactor systems through simplifications in the design. However, passive components/systems require extensive experimental and analytical investigations to ensure their reliability. Additionally, in-service inspections are needed. Ideally, the passive approach is completely independent of the active one and, thus, meets the diversity and redundancy requirements. A combination of both an active and a comprehensive passive approach appears to be optimal. As future systems are supposed to meet the sustainability criteria i.e. breeders or molten salt reactors, more inherent safety features are needed. These include e.g. a low-pressure coolant, low power densities, small control reactivities and negative feedbacks that lead to a self-shutdown in critical accident situations. Furthermore, comprehensive passive safety systems are of course also desirable for these advanced systems. These improved safety approaches appear necessary in light of a potentially rapid increase of nuclear power in the next half
