The design and performance of a core assembly orifice for gas-cooled fast-breeder reactors (GCFRs) are studied in this report. Successful reactor operation relies on adequate cooling, among other things, and orificing is important to cooling. A simple, yet effective, graphical design method for estimating the loss coefficient of an orifice and its associated opening area is presented. A numerical example is also provided for demonstration of the method. The effect of the orifice configuration on orifice hydraulic performance is discussed. The design method stated above provides a first estimate toward an orifice design. Hydraulic experiments are required for verification of the design adequacy.
