The KNGR uses Fluidic Device to control the flow rate of safety injection coolant from SITOafety Injection Tank) during LBLOCA. This Fluidic Device is a passive safety equipment and it is installed at the bottom of the inner space of the SIT. During the past two years, a scale model test to obtain the required flow characteristics of the device under the KNGR specific conditions has been performed using the experience and existing facility of AEA Technology(UK) with appropriate modifications. The performance verification test is to be performed this year to obtain the optimum characteristics and design data of full size Fluidic Device. This report summarizes the results of the model test.

The purpose of the model test was to check the feasibility of developing the device and to produce a generic flow characteristic data. The test was performed in approximately 1/7 scale in terms of flow rate with full height and pressure. This report presents the details of system performance requirements for the device, design procedure for the Fluidic Device to be used, test facility and test method. The time dependent flow, pressure and Euler number are presented as characteristic curves and the most stable and the most effective flow control characteristic parameters were recommended through the evaluation. A method to predict the size of the Fluidic Device is presented. And a sizing algorithm, which can be used to conveniently determine the major geometric data of the device for various operating conditions, and a FORTRAN program to produce the prediction of performance curves have been developed.

The conditions of this test are very specific, that is, the fluid is high flow water with a very small pressure difference between supply and control port. Therefore, almost no empirical test data is available. Consequently, the test results will be utilized as reference for the future development of full scale of Fluidic Device.

The KNGR is to install a Fluidic Device at the bottom of the inner space of the SIT(Safety Injection Tank) to control the flow rate of safety injection coolant from SIT during LBLOCA. During the past two years, a scale model test to obtain the required flow characteristics of the device under the KNGR specific conditions has been performed using the experience and existing facility of AEA Technology(UK) with appropriate modifications. The performance verification test is to be performed this year to obtain optimum characteristics and design data of full size Fluidic Device. The purpose of the model test was to check the feasibility of developing the device and to produce a generic flow characteristic data. The test was performed in approximately 1/7 scale in terms of flow rate with full height and pressure. This report presents the details of system performance requirements for the device, design procedure for the Fluidic Device to be used, test facility and test method. The time dependent flow, pressure and Euler number are presented as characteristic curves and the most stable and the most effective flow control characteristic parameters were recommended through the evaluation. A method to predict the size of the Fluidic Device is presented. And a sizing algorithm, which can be used to conveniently determine the major geocetric data of the device for various operating conditions, and a FORTRAN program to produce the prediction of performance curves have been developed.
