Steam injector (SI) is known as a static jet pump using steam and water as working fluids and is expected to be introduced as an emergency safety system of next-generation nuclear power plants. In this study, we developed the evaluation method for thermal fluid behavior and operation characteristics inside the SI and performed comparison verification with measured value by experiment.
