Influence of Coolant Flow Direction on Criticality Waves

摘要

Two models for criticality wave systems are presented, distinguished by the coolant flow direction with respect to the wave propagation direction, namely, an upstream wave (UW) model and a downstream wave (DW) model. It is shown that in the DW case the reactor power and wave velocity are considerably lower than those in the UW case, but the burnup is much higher.
