We are developing technologies for "Innovative Simplified Nuclear Power Plants" in order to improve the economy and safety for the further nuclear power plants. The purpose of our developing technologies is to significantly simplify equipment and reduce physical quantities by applying "High-Efficiency Steam Injector (SI)". It is applicable to wide operational ranges beyond the performance and applicable range of existing steam injectors. We adapted the multistage SI and parallel operation to replace the low-pressure feedwater heaters with SIs. Emergency Core Cooling Systems of nuclear power plants can be replaced by SIs to achieve high inherent safety free from severe accidents by keeping the core covered with water (Severe Accident-Free Concept). This report describes the demonstration test of the visualization of water injection into the core by applying a Low-Pressure SI to validate the capability of a SI-driven Core Coolant Passive Injection System. This research project is carried out by Tokyo Electric Power Company, Toshiba Corporation, and six Universities in Japan, funded from the Institute of Applied Energy of Japan as the national public research-funded program.
