In nuclear power plant, the reactor cooling system has maintained high-Reynolds-number flow above 1E+07 to cool a heat generated by the reactor. To minimize uncertainty for flow calibration, it is necessary to install a flow simulation system to maintain the high-Reynolds-number flow. Y-connection is selected to connect four (4) parallel high flow circulation pumps for minimizing system pressure loss. This paper describes the characteristics for Y-connection by computer flow simulation. It was confirmed through the results that the pressure loss of the Y-connection was lower than that of T-connection, and that the pressure loss of the connection was similar sixty degree (60°) and below of connection angle.
