Reevaluation of Core Damage Frequency in Light of the Occurrence of Complex Transients at B and W Plants

摘要

This paper presents a unified treatment of ''complex transients'' and core damage events, with the aim of relating the frequencies if the two types of events to each other and to the frequencies of their constituent events. This framework provides a basis for relating the observed frequency of certain transient types to core damage frequency, and deciding whether the occurrence of complex transients means that core damage frequency is higher than it was previously believed to be. 5 refs.
