Abstract

Several key phenomena and alternative scenarios which may follow a loss-of-heat-sink event, with scram, in an LMFBR are discussed. An event tree procedure is used to highlight the major branching points as they relate to controlling phenomena in the accident progression. For each of these branching points, a discussion of results of analyses carried out at BNL is presented. These discussions focus on the inherent safety capability features of the LMFBR concept as well as on particular design features of the Clinch River Breeder Reactor and of the Fast Flux Test Facility.
