The OECD Nuclear Energy Agency (NEA) Science Committee (NSC) established the Expert Group on Multi-physics Experimental Data, Benchmarks and Validation (EGMPEBV) in 2014 to bridge gap between advanced, multi-physics simulation capabilities relatively low availability of dedicated, high-fidelity experimental data benchmarks specifically for modelling tools. EGMPEBV was mandated establish mechani...

In case for nuclear power plants long-term service operation over their design life, it is necessary to calculate reactor pressure vessel (RPV) strength and durability acknowledgment (static strength, under cyclic seismic loads, brittle fracture resistance (BFR) include) the as one of most important NPP structure. Usually, according assessment, RPV resource determined, that is, time its subsequ...

The main purpose of this study is to perform numerical simulation of nanofluids as the coolant in VVER-440 fuel rod bundle. The fuel rod bundle contains 60 fuel rods with length of 960 mm and 4 spacer grids. In VVER-440 fuel rod bundle the coolant fluid (water) is in high pressure and temperature condition. In the present Thermo-hydraulic simulation, water-AL2O3 nanofluids containing various vo...

The modern direction in the study of safety nuclear power plants is to ensure maximum level detail process modeling with a satisfactory computational resources. One approaches such task solving coupled use special software required levels detail, for example, systemic thermohydraulic codes hydrodynamics codes.
