Space nuclear reactor power system (SNRPS), especially megawatt level, is very attractive for the future civil and military space demands. The high-temperature gas-cooled coupled with closed Brayton cycle (CBC) can achieve high-power output applications. For SNRPS CBC, dynamic models all components, including reactor, turbine, compressor, alternator, ducting, pump, recuperator, gas cooler heat pipe radiator, are developed in this article. Then, a transient analysis code (SAC-SPACE) to...
The development of deep space exploration requires nuclear reactor with higher power and better endurance. In order to meet the increasing high requirements for applications, an Open-grid MEgawatt Gas-cooled spAce (OMEGA) is proposed in paper, which featured low specific mass energy conversion coefficients. A set models, including neutron kinetics model, reactivity feedback model heat transfer are established. Besides, system analysis code (System Analysis gas-cooled Reactor [SAMER])...
Flow channel contractions and expansions often lead to flow separation accelerated fouling deposition, particularly around the tube support plate (TSP) in steam generators. This study employed large eddy simulation (LES) coupled with discrete phase model (DPM) analyze deposition mechanisms at various locations within these configurations. Simulation results were compared Reynolds-averaged Navier–Stokes (RANS) models, LES showing superior predictive accuracy, especially when sub-grid-scale...
Flow-induced vibrations pose significant risks to the long-term operation of helical coil steam generator (HCSG). Developing effective mitigating measures heavily relies on clearly understanding internal turbulent flow. This study investigates helium flow within a 30-degree central region heat transfer assemblies in HCSG high-temperature gas-cooled reactor utilizing shear stress transport based improved delayed detached eddy simulation. The complex vortex structures are effectively captured...
