Abstract

Dynamic Safety Systems (DSSs) are reactor safety function systems that are functionally controlled using dynamic rather than static processes. All components including software, whose failure could result in a critical safety system failure, are operationally verified by hard-wired components. Dynamic Safety Systems have been developed in the United Kingdom by AEA Technology for use in gas cooled reactors. One such system, known as ISAT, will be described in this paper. Through use of scenario testing of a DSS emulator on a BWR plant training simulator, it is shown that a DSS can provide a cost effective safety system in BWR power plants
