A new design for the flow control component of an advanced accumulator (ACC) was introduced and numerically investigated in the paper. The flow control component can produce high flow rate and low flow rate at the different stages during the safety injection. The FLUENT computational fluid dynamics (CFD) was used in the simulation of the flow pattern in the flow chamber and the outlet. The flow pattern and pressure gradient in the vortex chamber were investigated. The results show the design can realize the high flow and low flow in this design.
