In order to analyze the various safety features of the reactor, the quantification for the flow and pressure distributions are very important. A test facility, named “SCOP”, was designed based on the conservation of Euler number which is a ratio of pressure drop to dynamic pressure with a sufficiently high Reynolds number. In order to preserve the flow distribution characteristics, the SCOP is linearly reduced with a scaling ratio of 1/5. For the present work, a total of 9 tests were performed for a nominal SMART flow condition. By using the test results, a statistical final flow distribution for the SMART reactor were presented. The current data could be applied for the validation of a CFD analysis method as well as reactor safety and system performance analyses.6 pagesPDFenUniversity of PretoriaSMARTSystem-integrated Modular Advanced ReacTorPressurizer inside the reactor vesselPressure distributionsSCOPConservation of Euler numberFlow distributionCFD analysis methodReactor safetyPresentation
