Purpose: The goal of this paper is to present the facilities designed and built in the frame of the SUSEN program in the Centrum Výzkumu Řež, allowing research and development in the area of Generation IV and nuclear fusion reactors. Design/methodology/approach: The coolants investigated are: supercritical water, helium and lead-bismuth. The SSD team is in charge to perform in hot-cells various kinds of mechanical tests on irradiated materials in the range from room temperature to 800°C (tensile test, creep test, tension-torsion test and fatigue test in different type of loading) and microstructure investigation with SEM and TEM. Findings: SUSEN project allows at CVREZ to develop the facilities and instrumentations that institute has already had. This project allows also developing new facilities, buying new experimental machines and gives a wide range of investigation in different field in the research and development of Gen IV reactor. Research limitations/implications: The different types of loops study the impact of media on the properties of structural materials. The behavior of media and the different type of mechanical tests in static and fatigue regime at different temperatures enable to extend the limit of knowledge about mechanisms of corrosion, mechanisms of degradations and improve the design and safety in nuclear power plant. Originality/value: The SUSEN program is divided in four sub-programs and teams: Technological Experimental Circuits (TEC), Structural and System Diagnostics (SSD), Material Research (MAT) and Material Fuel Cycle (JPC). TEC team is in charge of the development large-scale experimental loops to improve the quality and quantity of data about the behavior of coolants used in the primary circuit and the corrosion of steel in contact with coolants.
