The availability of metal-fueled fast reactors can be improved by the elimination of scrams caused by a class of low-flow events by taking into account the inherent reactivity feedbacks acting during such events. With this approach, the flow signal normally used in the loss-of-flow (LOF) protection system has its trip setpoint substantially reduced, and the power-to-flow signal is used with a normal trip setpoint. This permits the safety system to more closely monitor the safety of the reactor, i.e., its temperature rise as indicated by the power-to-flow ratio, and to avoid the initiation of a scram during an event in which the flow is decreasing but the core temperatures are remaining within prescribed limits. During such events, the inherent feedbacks act to reduce power and thereby limit any temperature or power-to-flow increases despite substantial reductions in the flow. This approach was applied to such an incident in Experimental Breeder Reactor II and was shown to avoid the scram that actually occurred while providing reactor protection. Additional calculations were performed illustrating the range of applicability of this type of LOF protection.
